2010 Roehr 1250sc First Ride
Roehr wanted his superbike to be 100-percent American made so what other options would he really have for the engine other than the H-D V-Rod? Well, nothing really as the well of American-made motorcycles is pretty dry these days.
One man, a shed and a dream. This sums up the Roehr 1250SC pretty well. But where most would think this implies shoddy engineering and seat-of-the-pants design, take a quick look at the quality and fit and finish of the American-made V-Twin Superbike and one can’t help but be impressed. It really is quite staggering. Keeping this in mind as you ride the supercharged Harley-Davidson V-Rod-powered sportbike and the level of performance is just plain awesome. But the key is to do exactly that and not try and compare it to the million-dollar-plus engineered Japanese or Italian sportbikes, because, well, that’s just not fair to the one man, his shed or his dream.

American-Made Muscle
The Roehr is kind of like a supped-up Mustang or Ford GT. It’s 100-percent American made and beating at the heart of the beast is a liquid-cooled, big-bore V-Rod engine with a supercharger on it, much like those fast-Fords. Why a V-Rod you might ask? Well, despite the fact it’s made for a cruiser and quite heavy, according to Roehr it’s engineered to be durable and for the most part it’s about the only decent American-made engine capable of making the kind of power they wanted for this bike.

“It’s basically the VR1000 Superbike engine of old but reengineered for the cruiser,” explains company founder Walter Roehr. “The engine is great and well-made, and can handle loads of horsepower being pumped through it. The only downfall is the weight. The engine itself weights almost 100 pounds and in a 400-pound bike that’s a lot. This is why having it make good, useable power was a key. As well as trying to make the rest as light as possible.”

2010 Roehr 1250sc Dyno Chart
167.5 hp and 99.5 lbs-ft of torque at the rear wheel! That's impressive by any standards.
In fact, the V-Rod engine was actually developed in conjunction with Porsche AG originally. Bet you didn’t know that, did ya? The result was an 1130cc (now available in 1250cc) liquid cooled, DOHC, eight-valve, 60-degree V-Twin engine, named the "Revolution" by H-D, with performance characteristics only a large-bore short-stroke architecture can provide. But Roehr needed even more for his motorcycle so he fitted a supercharger to his beast, but we will go into that in a minute. The internal configuration of the Roehr superbike engine has a relatively stock 1250cc V-Rod engine with a 105mm x 72mm bore and stroke, 11.3:1 compression ratio and 5-speed transmission. Handling the exhaust duties are a set of custom-fitted R1-spec Akrapovic carbon mufflers mated to hand-fabricated headers.

As revolutionary as the V-Rod engine is, it’s still a cruiser engine so the power is nowhere near what Mr. Roehr needed for his big-buck modern sportbike. And while it is possible to make the engine quite fast in naturally-aspirated from, the more logical and cost-effective way to reach this goal was to think outside the box. Forced-induction was the logical choice for this application so the RSS (Roehr Supercharger System) was born.

2010 Roehr 1250sc First Ride
The Roehr-designed Bi-Metal frame features both Chrome-Moly and T6 Aluminum in the same unit.
Inside the RSS sits a Rotrex C 15-60 centrifugal unit that weights only 6.4-lb and is no bigger in size than a typical small car alternator. Inside is a patented roller-drive mechanism that provides an “extremely high step-up ratio.” The ratio is 12.7:1, which means maximum air from the slimmest possible size. Other tidbits inside include a special bypass valve that is designed to re-circulate unneeded air back into the compressor during certain operation, such as idle, cruise and deceleration, which effectively unloads the unit and reduces drag on the engine. This basically then negates the supercharger and lets the engine function as if it were stock in those less-demanding situations.

The bypass valve shuts under acceleration and allows the compressed air to pressurize the intake system. The Rotrex is also designed to deliver air in proportion to the motorcycle’s driven speed, by virtue of a system that increases the speed of the SC-unit to match the bike’s engine speed. The idea is that as a result power delivery will be as smooth as possible and it seems to eliminate that aggressive “hit” usually associated with forced-induction. This works from just above idle all the way to the rev-limiter. The small size and relatively low boost of the system also eliminates the intercooler typically needed with a supercharger, which aids in keeping weight down. And as for actual engine cooling, that comes in the form of twin side-mounted radiators, intended to keep the bike as slim as possible.

Housing this very untraditional engine is an equally unique frame. Featuring a Bi-Metal beam design, the unit is constructed as a blend of 4130 Chrome-Moly steel and T6 Aluminum. By blending the two his aim was to tune the proper flex characteristics into the bike, as a motorcycle frame needs to be much more than strong and stiff – it needs designed-in flexibility, mostly laterally, to allow it to function properly at both low and high speeds as well as while it’s leaned over. This is known as controlled-flex and is what provides the rider feedback and offers some level of dampening when the bike is carving through a turn.

2010 Roehr 1250sc First Ride
Top-shelf components such as Ohlins suspension and Brembo brakes grace the Roehr 1250SC.
The chassis as a whole is designed with computer-assisted finite element analysis and the main beams are produced using large-section, thin-walled 4130 steel. This is bonded and bolted to “extremely strong, stiff, yet lightweight” billet aluminum swingarm pivot plates. This combination is where the ‘Bi-Metal’ name comes from. Mated to this is a single-sided swingarm to round out the basic chassis.

As for the suspension, they spared no expense and went straight for the top – Ohlins. Up front are the Swedish suspension expert’s Road & Track fork and out back their fully-adjustable (compression, rebound, spring preload and ride-height) rear shock. Equally as top-spec are the Brembo brakes: Monobloc 4-piston calipers gripping a pair of 320mm rotors up front and a 2-piston lightweight caliper gripping a single 245mm rotor on the back. Mated to those are big-buck Marchesini wheels shod with Pirelli Diablo Corsa 3 rubber (120/70-17 front and 190/55-17 rear).

And while some of the components are sourced out, the design of the bodywork and its composite construction are done by Mr. Roehr himself – although they do take some direct design cues from Ducati’s of yesteryear up front and Yamaha’s of recent-year out back. But a lot of this is a matter of form following function, you see, as the chassis has a very Ducati-like layout to fit the large V-Twin engine and the tail section uses R1-sourced exhaust, thus these design elements are more than pure copies. As a result, I must say, I do like how it looks.
2010 Roehr 1250sc First Ride
Power from the supercharged V-Twin is extremely useable. 

Feeling the Power
We were able to sample the machine both on the track briefly and more extensively on the roads. And first things first, this is a machine designed for the street. So, to be fair this is where we based most of our evaluation. Good thing, too, because in the world of B-roads and canyon passes the Roehr is right at home. It works reasonably well at the track but without a doubt, the power and the unorthodox way in which it’s produced, is more suited for street riding. Very few production motorcycles utilize forced-induction so this wasn’t something I was used to. In fact, it was the first sportbike of this kind I’ve ever ridden.

Thankfully, it’s well engineered and the ‘scary hit of power’ commonly associated with other forced-induction-powered bikes just doesn’t exist on the Roehr. But, that’s not to say it isn’t fast. In fact, it’s quite the contrary. Power comes on from low rpm smoothly and gets the American-made 1250 moving with some serious steam. As one can see from the dyno chart it makes 167.5-hp at the rear wheel, which is nothing to scoff at on any level.

This type of power delivery is exactly what is needed to make it a fun and entertaining sportbike on the street. And while Walter himself can tell me how great that engine is and the potential it has until he’s blue in the face, it’s hard to get your head around it until you actually ride the thing. And after riding it on the roads, there’s no question the supercharged V-Twin philosophy works very well.
2010 Roehr 1250sc First Ride
Hey, is this thing legal for the Daytona Sportbike class?

On the track, not everything is quite as glowing though. It certainly feels like a racebike but it is on the heavy side to be considered a pure track weapon and since we were riding it at the same time as our open-class bikes at Infineon Raceway during our 2009 Superbike Smackdown we were able to feel how it stacked up against the 1198 and the latest from the Big Four. Starting with the positives it certainly hustles around the track good enough that I wouldn’t hesitate to use it at a track day. Although it needs some higher-spec tires if you plan to push it hard. The Brembo brakes are very good and the suspension components have the potential to handle anything the average Joe can throw at it. We found it was a little soft for our preference but we didn’t get much opportunity to make adjustments since we were at a Pacific track Time track day.

Seating position and ergonomics feel very much like a Tamburini-era Ducati. The reach to the bars is a bit stretched out, the tank is long and skinny, the riding position is aggressive and the cockpit itself is reminiscent of the Italian Twins. It’s no surprise that the bike behaves in a similar manner as well. Both geometry and layout are similar since there are not too many ways of fitting the long motor into such a compact frame. As a result steering is a bit heavy initially, but once set in the corner and on its side is very stable and solid, offering ample feel to the rider through the bars.

2010 Roehr 1250sc First Ride
Considering sitting between those Roehr-engineered frame spars is a massive V-twin engine from a cruiser, the performance is pretty amazing.
The Roehr superbike bike feels good once we get it up to speed on the track. It handles very similar to the 1198 though it simply doesn’t have the gearing to keep pace with its Italian counterpart. Initial power is on par but it runs-out quickly as we were often hitting the rev-limiter while finding that happy medium between getting a good drive and battling to keep traction from the stock Diablo Corsa tires. The trick is to run it a gear higher than you think and carry a bit more speed in order to keep the engine in the meat of the power. The linear power delivery comes on down low and in the middle of the rev range but don’t let it dip below 4000 rpm because there isn’t much usable power available down low when you’re trying to go fast around a race track. It has a lot of torque, 99.5 lb-ft to be exact, which is awesome on the street or the track. The torque curve reveals a linear spread across the range, similar to the horsepower curve which climbs smoothly from 4000 rpm on up to the 9250 rpm peak. The problem is that the engine hits redline before ten-grand so there’s not much margin for error when connecting corners on the track because it builds quickly. But, like we said earlier, this motorcycle was not intended to be a race bike. It’s a hand-crafted American-made superbike for people who are tired of following the crowd. It’s unique and it’s pretty fast, plus it gets around the track fine if you aren’t hoping to qualify for an AMA National.

2010 Roehr 1250sc First Ride
The single-sided swingarm is very Ducati-looking. In other words, it looks good...
Much of the reason the Roehr can hold its own on the track is due to its well-engineered frame, swingarm and the top-level suspension components. Sure, it’s on the heavy side, tipping the scales at 490-lbs full of all fluids, but it carries the weight pretty well. This may sound high at first, but it actually is only 14-lbs heavier than the 476-lb wet weight of our 2009 Yamaha R1, and I would venture to guess the H-D engine weights double that of the light inline-four in the Yamaha.

So everything sounds amazing, right? For the most part, keeping everything in context, the Roehr is an amazing machine. But that context involves riding it mostly on the roads. The track isn’t where it’s designed to be and while it can hold its own, it’s definitely not where it’s most at home. It would be okay for the occasionally track day to mix in with the weekly canyon runs, though it’s not going to be the basis for a race bike. So, where does it belong in the grand scheme of things? It is the culmination of one man’s vision, his dream of making a motorcycle from scratch that incorporates his design and his goals. It may not be the bike to lure Gixxer punks away from Suzuki but it will appeal to a more affluent club. The rider who wants to be different, who wants to stand out from the crowd and be able to boast of a supercharged V-Twin and a list of top-shelf components that will keep any bench racer happy for quite some time. The only real hurdles for Roehr are going to be price and timing. The demand for a $42,500 sportbike can’t be huge right now, but we will be pulling for the official launch of the Roehr 1250SC Superbike to be a successful one.

Kevin -Amazing quality, and tons of torque  May 6, 2010 12:24 PM
I must say it is VERY beautiful I saw it in person at the Rock Store in Malibu. The marketing director rolled up on it. It is a wonderfully made bike. It is a rival for MV Agusta. As far as the engine: It makes a little more power than the rest of the superbikes, it weighs more, but it makes about 20lb-ft of torque more. Maybe one day he will be able to make his own engine that is lighter and doesn't need the supercharger. But keep the SC engine too, it is just cool. As for price. It is hard to make a first bike that will be cheap. You need a reputation to sell a lot of them and a new company does not have that. It is much easier to start off with an exotic and work your way down.
Terry P -Roehr 1250 supercharger  January 8, 2010 05:30 PM
I do not mean to throw rocks at another mans dream, but last time I looked, Denmark (the country that the Rotrex supercharger is made in) was not part of my fine country, the USA. Still a fantasic motorcycle though.
Einstein -Congratulations  January 7, 2010 12:13 PM
Obviously the Roehr isn't perfect, it isn't even a realistic alternative to what comes out of Italy, Japan, and yes now Germany. But you have to love an American who is willing to stick their neck out and make a pretty good first attempt at actually building a REAL sport motorcycle, built in the US, that is performance based and will honestly out accelerate a golf cart. The Porsche/HD motor is great alternative when you need to develop a chassis but what we really need is a developed and built in the US Superbike engine, ala Michael Czysz, that can be race developed for street reliability. C'mon Roehr, don't stop now we are looking for that American entrepreneurship and ingenuity to develop a motorcycle engine everyone in the world knows we can build. If Gm and Ford could go F1 racing I know there is someone like you who can build a motorcycle engine for Superbike. I'd love to see it in my lifetime, PLEASE!
Bimota Rich -like it dont love it  January 7, 2010 04:37 AM
I agree with his decision on an American engine (though I am not sure how American the Rods engine really is... but it is too much of a porker for sport bike duty I am afraid... and the rest of the design looks decent but it is nothing special nor particularly beautiful... And for that price it better be either particularly beuatiful or particularly good performance... it is neither so I do not see it making it... to bad cause the frame looks great and seems to have potential. If it all looked less tacked together from other bikes and had more of an original look and beauty then it would more likely have an audience.
Rick S -$$$$$$$  November 17, 2009 11:11 AM
It looks nice, has very nice components, decent performance but $$$$$$. I would purchase an MV or a Bimota for this price before the Roehr. Drop the engine and put in something else with less weight and it would be sweet!!!
Fred -roehr  November 1, 2009 02:38 AM
looks cool but its too expensive and not enough performance.

Oh Boy I can't wait to get one of these and put some Screaming Eagle pipes on it. Maybe I would qualify to wear all the cool HD clothes and stuff to.
John -Uncle B - Detriot: Johannesburg of America needs Honda "50"'s Urgently  October 10, 2009 05:22 PM
Uncle B clearly has issues, a bit paranoid maybe...but his comments were very limited regarding motorcycles.

Bottom line, criticisms can be levied against anything that is manufactured; i.e. cars, bikes, planes; it doesn't matter. If someone purchases a Roehr, and is happy with that purchase, that's all that matters.
Deep707 -american sportbikes--  October 6, 2009 04:14 PM
well not bad on the design. Not super exotic but sweet looking. Nice components but there not all american. A company called fischer also made a superbike with components from european company. I have a honda rc51 tricked out and it would most likely spank this bike. It has less hp but it has all ohlins and racetech components. Why make a bike thats overpriced and can't compete with the japs and euros, I mean seriously that is a such a unlogical project. My point of view on this prototype is keep it a prototype. Im 24 and have had already 4 tricked out sportbikes. Ducati, triumph and this is my 2nd honda. Goodluck towards the manufacture/ sorry engineers who designed a ripoff. LOL PEACE.
Uncle B -Detriot: Johannesburg of America needs Honda "50"'s Urgently  September 25, 2009 01:22 PM
The social holocaust about to befall an unsuspecting American population over the next few decades, will revise the history books, and change life here forever! The anachronistic "Harley" engines, and V-8 gasoline burners, will be displaced by battery cars, bikes, built to ballast Wind and Solar installations, save for a few gas museum pieces, run on very expensive, super taxed ethanol. The glory days of internal combustion engines are over! We will by-pass the more efficient Euro-diesel and go directly to the battery car and Depleted Uranium Super-Batteries, now held in military secrecy, but leaked to the web from time to time by Patriots! China is about to rear its ugly head in the Iran conflict, and effectively 'Smack Down" American overtures for world domination, and may even give Iran full access to its nuclear knowledge - a considerable known resource, with huge advances unknown and undecipherable by our under-educated scientists. It was developed while we were asleep at the wheel, on pot and booze and monumental ego tripping adventures with militarism, greed, sloth, gluttony, lust and pride! The V-rod engine, an out of balance anachronism from the radial aircraft engines of the 1920's is historically lost in time! Try a flat 6 Honda engine on for size and cut the romantic, little boy, vroom-vroom, one potato,two potato, nonsense! I call Bull crap on the V-twin, and back multi cylinder flat engines as the peak for development of the now defunct gasoline engine era biking craze, and look to new and exciting, and silent electric bikes. please kick me for saying this but reality knocks on Americas door as we speak and we must move on! Last Call America! Last Call!

hey scooterstock the ford gt ain't 100% American made. lol go look it up almost all the parts are from out of America that's why that car isn't half bad lol. don't get me wrong i got nothing but love for the States, but they cant make cars or bikes if they had to.

I'm American and I'm embarrassed by American designers who stand on the soap box spouting out the made in American mantra and produce expensive stuff like this that just doesn't compete. Especially since a lot of it isn't made in America. We're the laughing stock of world. And no I’m not a designer or engineer and I don’t try to be. But at least I didn’t build an inferior bike and then use the ‘Made in America’ marketing line to sell it. Look at their ads in magazines – that’s the only thing use to sell it because that’s all they got. Sad.
Charlie -American sport bike  August 26, 2009 08:50 AM
I don't know about everyone else but the sound that comes out of that thing is horrible its sounds like a cruiser :( Why? Because its a Harley motor which sounds so wrong in a sport bike. I like my sport bike to scream when it goes down the road screeeeeeeeeeeeeeeaaaaaaaaam!!!!!! I'll pass on this bike even if it was cheaper. I as an American would love to see a true American made sport bike designed and built from the ground up. I know we Americans can do it but the Japanese are going to be hard to beat.

It shows when American spend 3 times $$ and using 80% import components to build a bike, it can almost compete with a Japanese or Italian. Well done….
Les -Roehr 1250SC  August 25, 2009 11:30 AM
Incredible job using the VROD engine. Now everyone can understand why Buell used a Rotax motor. It's great Harley powered bike but it's not a great bike. It's not a race bike but it can almost compete(almost). Roehr and Buell are both genius' for using what they have to work with.
I sincerely hope that Roehr succeeds with his designs.
JIM -AMERICAN MADE SPORT BIKES  August 24, 2009 07:10 PM
IT'S A SHAME THAT THE COUNTRY THAT BUILDS THE BEST FIGHTER PLANES IN THE WORLD CAN'T PRODUCE A SPORT BIKE THAT CAN COMPETE HEAD TO HEAD WITH THE JAPANESE AND ITALIANS! ALSO, IS THERE SOME SORT OF LAW THAT SAYS AMERICAN MOTORCYCLES HAVE TO BE V-TWINS? I CAN PROUDLY BY A AMERICAN MADE CAR, BUT NOT A MOTORCYCLE. I WOULD IF THERE WAS ONE TO BUY!
That's -the point  August 24, 2009 10:11 AM
Mcguire, if you have to outsource the brakes and suspension to get the best - why not the engine? I think everyone agrees that the engine is ill suited for a sportbike and was only selected so that the bike could have an 'American' engine - even Buell has moved to other engine sources.
Mcguire -Roehr  August 24, 2009 02:55 AM
It is a outstanding engineering job just to get that big motor into a sportbike frame much less make it fast. Outsourcing brakes and supension is necessary if you want your bike to have the best components and all the manufactures do it. If every bike manufacture had to build 100% of the parts in house there would be about 1 still in business (even Ural and Enfield outsource parts). Congratulations for getting the prototype built and it shows the dedication Mr.Roehr for spending the fortune it cost to build such a machine.
x2468 -globalization  August 23, 2009 10:50 PM
I don't think there is a single bike out there that has EVERY single piece made in one country. So it's stupid to expect that. KTMs use Brembro brakes and Magura clutches. No one says they aren't Austrian because of it. And their of examples like that with virtually every motorcycle company. It's the nature of the times.
Tom Brooks - Roehr 1250SC - nice KIA bike - NOT!!!  August 23, 2009 02:43 PM
It’s more like US assembled … engine-german, suspension-swedish, breaks & wheels-italian, exhaust-slovenian … maybe mirrors are US made??? … saunds like an old KIA bike …. but then we all know US can’t make but crap!
Common sense -Where are the custom parts?  August 23, 2009 09:18 AM
For that kind of coin I want to see custom billet parts everywhere, e.g. brake and clutch levers. Triple clamp and Swingarm don't look like high dollar items either. Mirrors don't look like they belong on that bike and they don't match the signal markers at the back. Bottom line this bike is missing a lot of the special details that the asking price requires of it. Kudos for taking on such an effort but Roehr really needs to consult a designer. As it is I don't seen how anyone would take this over a 1098R, Bimota DB7, F4 RR 1078, etc. not to mention they cost less.
Speedjunkie -Too much for too little  August 22, 2009 08:37 PM
Why buy a jigzaw puzzle when you can have a masterpiece for much less !!! My money goes for the Ducati blindfolded !!!: )
Jordan -Roehr  August 22, 2009 05:00 PM
If you don't want to be compared to all the japanese and italian bikes out there don't make your bike look like the love child of a MV F4 and a Yamaha R1. Also for $42K I think an all digital race dash/gauge like in the $13K Ducati 848 could be thrown in.

I hope the final bikes have better build quality. Bimota does it better and for less money and they don't make a zillion bikes.
Nathan -Terrible!!!  August 22, 2009 10:33 AM
Zoom in on the picture of the frame ( it's the one below the dyno graph). The upper portion of the frame looks terrible! There appears to be some incredible bad welds just above the screw for the fairing mount, and the surface is very wavy and blotchy. Not only would I not pay for this bike, I wouldn't ride it for free. If they care so little about quality and craftsmanship that they would leave such atrocious welds exposed just imaging what they have done where you cant see! As far as I'm concerned, that bike potentially poses a extreme risk to it's rider.
How do you define -an American Sportbike?  August 21, 2009 08:44 PM
Is the the powerplant? The Buell 1125R sportbike uses an Austrian made Rotax engine, so by this definition the Buell is not American? I think the bi-metal frame design is kinda cool, but everything else seems kind of derivative...
how much performance -would be gained  August 21, 2009 07:18 PM
if they simply swapped out the heavy HD engine for a lighter one?
Art -Roehr  August 21, 2009 06:50 PM
Bottom line is he put a HD motor in a not so new frame design. Slapped japanese suspension on it, with italian brakes. So what did he design? Nothing special. The Britten from New Zealand is the only bike that was built from scratch in a garage. So the Roehr was made in the USA, big deal, so is my Honda.

"The price tag is not important, the accomplishment of building this bike is outstanding"!

So how many are you going to buy Steve? Heck, if the price tag of an item wasn't important we would all have our own private jet. Besides, people would pay and do pay 42K for motorcycles, if the bike is worth it, this bike is not. Other than being different what does this bike offer?

socalmoe -Nothing Special  August 21, 2009 03:50 PM
I saw this bike at Glendale HD; there is nothing special about it. For that kind of $$$$ I would buy a high end Ducati fully race ready. Get back to us in 12 months and let us know how many were sold; my bet is that no more than 3.
Steve -Stuck on price  August 21, 2009 11:20 AM
Too many guys are stuck on the price tag. The reason a Japanese liter bike is so inexpensive is because they make a zillion of them. This is a custom bike, and a pretty cool one at that. What do you think people would pay for a custom chopper? Or better yet, a chopper with a fuel injected and supercharged engine, top shelf suspension and brakes, and custom bodywork?

The price tag is not important, the accomplishment of building this bike is outstanding!
Tim B -Let's Be Real  August 21, 2009 09:25 AM
American bike? Come on. Please let me know what percentage of parts on that bike, especially the engine, are designed, manufactured and/or built in the USA! Go ahead...I dare ya!

Why do you think Buell went to Rotax for the 1125R's engine instead of using the Harley V-Road engine? Because it's a tank. Only the supercharger could save it. But $42,000 for performance you can match for less than half of that price with a Japanese or Italian bike? No thanks. For that price, give me a Ducati 1098R or 1198R instead.
dgover -Wrong Engine  August 21, 2009 09:07 AM
I like the style and look of this bike. But he sourced the wrong engine. Designers need to stop making decision from the top of the 'Made In America' soap box. Brembo and Ohlins aren't american made so why would he care that the engine is (which technically I challenge because it was engineered elsewhere). He should have sourced Ducati's 1098 or 1198 engine or better yet Aprilia's new v4. So he sourced the wrong engine and then needed to add complexity in the way of super charger to it to get into the same performance league as his competitors. Just stupid.
Fred M. -Uh, Buell?  August 21, 2009 08:09 AM
Let's not forget the Erik Buell has made successful, innovative street bikes and, while Harley now owns a controlling interest in Buell, Erik Buell was one guy working in a barn making motorcycles. In a 2006 interview, Erik Buell had this to say about the V-Rod engine: “It’s too big! It actually was our engine. We started the project and then Harley got engaged and said that we’d like to use it too. And then they said, well actually we’ll probably gonna use it first. And then they thought about it and what bike they could build around this engine. They came up with this big touring cruiser. The engine as we had conceived it was too small. It was wrong. And they said that we want, like in all our bikes, the engine to be a showcase in the middle. In a 66inch wheel-based bike this little engine would just look stupid, so they made it bigger. I said, you know, it’s no longer a sporting engine. It’s a big twin, and a beautiful engine for that kind of bike. But, for me again, sport means nimble, athletic, light and it just became a big beautiful touring cruising engine. I just had to go; you know my customers won’t be satisfied with it. And it’s heavier than the air-cooled, significantly heavier without the water and radiator. I had a target of 140 pounds and it’s (V-rod engine) 210. Nothing wrong with it, it’s just not for our bike.” All that said, I hope that Roehr succeeds and that the bike makes people happy. The vast majority of riders on Japanese liter bikes, Ducati 1198s, etc. would be faster, smoother, better street riders with engines that were less peaky, in frames with ergonomics designed for 70mph average speeds instead of 130mph average speeds, and with suspension tuned for the street rather than for ultra-smooth race tracks. So the fact that the Roehr is not a joy on the race track does not necessarily mean that it's a bad choice on the street.
Nick -Roehr  August 21, 2009 07:00 AM
I also say he deserves a round of applause. Bikes like this are bought by rich dudes to show off, and if I were a rich dude looking for something American and unique, I'd definitely buy one of these over a Confederate.
Jake -Roehr 1250  August 21, 2009 05:02 AM
While I can appreciate the effort of Mr Roehr, I would have more appreciation from it if he had used more original imagination and creativity when designing the bike. If he wanted to use the V-rod motor that's fine and he's not the first to source a motor. But when looking at the bike the fact that it looks like he left parts off everything from a Yamaha R1 to a MV Agusta to a Ducati why would I be interested in this bike? Just because he is American? Why spend $42k on this when for lots less I could buy any one of the bikes that he borrowed from and have the real (and better) thing? Yes as an american it bums me out that with all the resources this country has no one can seem to offer a decent american made sportbike. Again much respect to Motoczysz but he was to me always more hype and self promotion than reality. Even without the rule change does anything really think his bike would have done anything other than run at the back of the MotoGP grid if it had actually raced? But my question if Roehr could get backing to build a production bike why has Czysz had so many problems getting his bike into production
Tessier -The one that made it  August 21, 2009 04:36 AM
If we look back a few years there where 3 american motorcycle manufactures all looking to be the first to bring there dreams to production bikes. There was Fischer Motorcycles, Motoczysz, and Roehr. Fischer was sourcing a Korean Hyosung motor to put in his frame and bodywork much like the Roehr story. They had some prototypes that where ridden by the press but alas it never amount to much more then that. Then we have Motoczysz which always have the intent of going racing and unfortunately had the rules changed right out from under them. They looked to be the most well funded and professional of all three of these outfits and hopefully there new direction of electric motorcycles will someday bare fruit but as of now it's just a beautiful design in someones shop. Hey at least we got a great documentary out of them in the form of "birth of a racer". Lastly there is Roehr based and built in some guy's garage this hodgepodge of parts become a road worthy motorcycle certainly not prom queen but somehow it is the only one of the bunch to make it to production and onto the streets of america. Congratulations!!!!! Lets hope that this economy doesn't kill Roehr and best of luck selling your baby. I speak for all the motorcycle community one this one and we look forward to seeing whats next from Roehr (maybe a naked version).

I think a round of applause for Mr. Roehr is in order. What an astonishing achievement! Lovely to see the mish-mash of (properly integrated) design elements - the Honda / Ducati cues... Clearly a person who has spent many an hour conceptualizing a "If i could, what would I do..."... and has done it! Leaves me with a warm feeling!
