BMW rocked the sportbike and high-performance motorcycle world last year with the release of the 2010 BMW S1000RR. This two wheeled missile went on to win both the 2010 Superbike Smackdown VII Street and 2010 Superbike Smackdown VII Track shootouts in its rookie year. BMW’s first true Superbike had our heads spinning with the cannonball-like hit of its Inline-Four engine and advanced electronics package that made it easier to command whether you’re blasting down your favorite back road or knee down at the racetrack.
 
ENGINE
 
But being the psychotic power junkies we are, even the mighty S1000RR isn’t quite fast enough. So in our quest for more adrenaline… err, I mean power, we fitted a Yoshimura R-77 Exhaust System available at Motorcycle-Superstore.com. This is Yosh’s top-of-the-line exhaust system designed for maximum performance at the track. The head pipe features a four-into-two-into-one design that terminates in a sleek trapezoid shaped muffler on the right side. Both the header and mid-pipe are constructed from titanium while the muffler is built from a mix of carbon fiber and titanium hardware.
 
The Yoshimura R-77 full exhaust system reduced the bikes weight by 13.1 pounds down to 437 pounds with a full tank of fuel.
As always cornering stability is a strong point with the BMW.
As usual Yoshimura craftsmanship continues to blow us away.
As usual Yoshimura craftsmanship continues to blow us away.
We can’t lie; the pipe is expensive carrying a price tag of nearly $2000. But for that money you get one of the highest quality exhaust systems available. When viewed up close, the attention to detail is exquisite. Every weld is precise and the finish of each component seems to help justify its lofty price. On the scales the pipe weighed 13.1 pounds less than stock unit which in turn reduces the Beemer’s fully fueled curb weight to 437 pounds.
 
Strapping the BMW onto the dyno proved the Yosh exhaust delivers power gains throughout its 14,000 rev range. From idle to 5000 rpm the stock system actually delivers just a hair more power but as soon as the engine spins past that threshold it’s pumping out more rear tire spinning horsepower and front wheel lifting torque. The power curve features a linear progression much like stock with nearly 80 ft-lb of torque (2.38 more than stock) arriving at 11,000 rpm and a whopping 183.08 horsepower (6.39 more than stock) coming some 2300 revs later, 700 rpm shy of redline.
 
In our stationary sound tests the R-77 delivers a significantly louder exhaust note with our sound meter registering 88 decibels, six points above stock. At half of maximum rpm (7000) the difference wasn’t quite as big only cranking out two more decibels than stock (100).
 
From the factory the S1000RR already had a relatively rambunctious exhaust note but the addition of the Yosh pipe makes it even better. At idle a much deeper exhaust note garners attention from other motorists at stoplights. Swivel your head before dialing in the throttle because if the law are anywhere within a 500-foot radius they’re going to be on you quick as the pipe emits a racy roar. Restrain your throttle hand and short-shift the engine and you’ll have an easier time going unnoticed so considered yourself warned. Furthermore if you want to go ultra-stealth then the pipe has an optional muffler insert that reduces the noise to a level comparable with stock.
 
CHASSIS
 
In stock configuration the BMW offers great handling and suspension performance under the vast majority of riding conditions. However those capable of zooming around the racetrack at professional-grade speeds might notice a quirk. The problem lies in the way the rear shock moves within its stroke. In order to get adequate levels of comfort and road compliance on the street yet firm damping when loaded heavily with the throttle, engineers were forced to design the rear shock linkage with certain compromises.
 
Zooming around the streets aboard the S1000RR.
The  799 Lees Cycle LCR link for the BMW S1000RR improves rear end feel and suspenion performance.
The OE-fitted Metzler Racetech K3 tires work well on the racetrack.
The LCR shock linkage changes the attitude of the motorcycle. For optimum results an ride-height adjustable shock needs to be installed.

The solution is to fit an LCR Link. The part is a direct, bolt-on replacement for the stock linkage. It alters the speed at which the shock absorber moves which makes the rear end of the bike feel more predicable when loaded on the gas. For more information check out the Lee's Cycle BMW S1000RR LCR Shock Linkage review.
 
Around the racetrack are where the handling improvements are most notable but we also like the way the bike rode on the street. The back end of the bike felt much higher than before but within a few turns we were comfortable with its new attitude. Yank on the twist grip and the rear end squats more predictably than before. It doesn’t just squat, spin and rebound like it did when it was stock. It feels like the rear tire bites into the pavement harder. This allows the rider much greater control when modulating power slides off corners.
 
We still encountered considerable wheel spin with the stock Metzeler K3 street tire but with the fitment of full-on race tires the link would allow us to explore the outrageous performance of the S1000RR in a safer and more controlled manner. Despite the more aggressive chassis stance, steering wasn’t overly quick and straight-line stability was unaffected. On the street, ride quality was slightly harsher but it’s something we can live with considering how much more planted the back of the bike feels when loaded hard.
 
While we really like the added sound and character courtesy of the Yosh pipe if you’re looking for straight up performance gains your money might be best spent with one of Yosh’s slip-on muffler. Handling wise the LCR linkage really impressed us. When ridden hard the difference in handling was night and day which makes this component a must-have for a track enthusiast.

Would love to go for the Yoshi system over the Akra. Why is Motocycle USA only measuring at 7,000 rpm? Does anyone know if the full Ti system complies with the 104dB sound limit for track use? I contacted Yoshimura and they replied that the db levels are 99.6db with and 102.1 without (the insert) at 5,500 RPM. They didn't have any other measurement other than at 5,000 RPM.

Does anyone know if switching the exhaust voids the BMW warranty, and what affect it has on being able to satisfy Calif emissions laws etc?

JSH is right about BMW bikes holding better resale value than the Japanese. Some even better than Ducs. S1000RR is the best value in stock form in terms of engine performance, excellent brakes and versatility. Thanks to different power modes it’s like having 3 different bikes. The looks, well, some like it and some don’t, but it personal choice. $2000 big boys for a Yosh – I don’t think it’s needed for the street, get the Akrapovic slip-on if you must have an aftermarket exhaust.

You probably shouldn't brag about how fast you are on the street, because there is no way you can really even know how a bike truly performs unless you are on the track. I agree pipes are probably a waste of money for the street, but if you pay a ton of money for a bike and then ride it on the street with a lame stock pipe then, in my opinion you are an old man, and no one cares what you say. I don't give a rats a** about resale, I just want a bike that screams and I can get that for less money with a Japanese brand.
JSH   February 14, 2011 03:28 PM
I'm not delusional or a liar, just telling it like it is. I am a BMW owner (also own 2 Kawasakis, a Yamaha, and a Suzuki) I bought a BMW R1150R in 2002 for $9995 and 9 years later the KBB is $5885. So it has retained 59% of the original value. That is outstanding re-sale value. None of the Japanese brands have anywhere near that high of resale.

hilarious-- once u buy the bike why do u need a dealer-- u gotta be kidding. bmw's have fantastic re-sale value-- welp i been known for tellin it like it is -- yer either delusional or a liar--which one is it? or maybe yer a total green newbie-- it's gotta be 1 o the 3. from readin your post -- its easy to see--you aint gotta clue.....

typo? Should have read as carving! lol
I'm sure that I am not the only rider to make his/her local streets a personal track at times. Having a corner hugger like a CBR1000 with a set of good tires seems to do the trick every time a missle wants to show off on the straights.
GhostRider11   February 13, 2011 09:14 PM
After years of craving up the streets, spending that kind of money on an exhaust system is pretty silly! As previously stated, all you end up with is an eye sore/empty wallet! I ride stock... nothing is more pleasing than passing/out-riding people that spent all their money on pipes and computer chips to go faster. When the corners come up all they see is my rear wheel... and it's a wrap! Leave all the after-market upgrades for track use because on the streets you will just get tickets from cops that want to bust your chops! I'd rather spend my money on a great set of tires and some tank grip pads.

The BMW S1000RR is $151 more than a Kawasaki ZX-10. Dealerships are far rarer than for the Japanese bikes but once you buy the bike why do you need a dealer? I do my own services and buy the parts online. As far as resale, BMW's have fantastic resale prices and BMW owners aren't scared off by bikes that have more than 10,000 miles. As to the article, the authors are just throwing away money. $2000 for a exhaust that is illegal to use on the highway! I guess you forgot that California just passed a law that bans aftermarket exhausts that don't meet EPA noise and emissions regulations. Considering the Yosh pipe eliminate Besides, the stock BMW has performance so far exceeding the skill level of the average rider what is the point? Your extra dollars are far better spent on a good riding school and some track days.
wildpig   February 13, 2011 10:30 AM
yea -- but its still a bmw-- bring more wallet...............and dealerships --- few an far between an mosre costly than other brand dealerships-- then talk about re-sale value-- there aint none.
adam motousa   February 12, 2011 12:42 PM
no way guys bmw s1000rr stock is as fast if not faster than zx-10r with pipe and ecu.
screamer69   February 12, 2011 10:44 AM
Cat, u ain't lying..the new Kawi ZX-10r makes 187/188 w/just a SLIP ON and ECU...plus the BMW ain't done S#@! in any Superbike class..
Cataclysm   February 11, 2011 03:58 PM
$2000 for 7hp? The weight savings is nice, but I sure expected more power gains given the fact that the cat is removed. That's saying a lot for BMW's engineers if they can design an emissions compliant exhaust/engine calibration that hardly loses any HP over race systems. Oh yeah, and I agree with the post below. Aftermarket exhausts generally look like garbage because the fairings don't go back like they used to. Love the 05'06 GSX-R 1000's fairing, but after that the giant "hole" started showing up on every bike. Gross.

your pictures do a good job of illustrating the gaping hole left in the bike after fitting an aftermarket exhaust. this is increasingly common on current model bikes with the large underslung pre-chambers that many manufacturers are using as part of the body work. i wish there were more solutions to fixing this. i think the exhaust manufacturers should take this into account and include pieces to smooth out or cover these holes after the installation of their exhaust. some do, but as of yet, most do not.
