Bridgestone Battlax R10 Race Tire Review

Friday, August 2, 2013

Bridgestone outfitted each of our motorcycles with its fabulous Battlax R10 and R10 EVO racing tires. The tires performed impeccably offering great grip  handling and excellent durability  too.

Considering that Bridgestone is the sole tire supplier to the MotoGP World Championship it’s obvious that the Japanese brand manufactures some of the stickiest, lean-inducing motorcycle tires money can’t buy. But what about the ones you can buy? Does its prototype technology trickle down to riders who have cash to spend and want the best performing sportbike tires for racing and/or apex strafing at track days? To find we used Bridgestone’s Battlax R10 and R10 EVO as the spec-tire for our recently published eight-bike 2013 Middleweight Supersport Shootout X.

The R10 model is Bridgestone’s premium motorcycle tire engineered for road racing. It’s an evolution of the older style BT-003 race tire that improves on every facet of performance from handling, to grip and road feel. Available in just one compound (medium or as Bridgestone calls it Type 3) and a single size (120/70-17), the front R10 employs an updated shape for enhanced steering response and line-holding precision through turns. (Bridgestone also offers an EVO-spec front tire available in a hotter running Type 4/hard compound — however based on its recommendation we ran the standard R10 front). The tread pattern was also re-worked and said to complement handling and reducing flex slightly during hard braking. The compound is designed to work in a wide range of asphalt temperatures, from less than 68 degrees Fahrenheit to in excess of 104 degrees. During our test the temperature of the pavement was in excess of 145 degrees at the hottest part of the day (115 degree ambient air temperature).

The Bridgestone Battlax R10 EVO tire was designed to perform in a much wider range of temperatures. This is what the tire looks like after two flying laps during Superpole.

Bridgestone had mixed results with its original R10 rear tire as tested during the 2012 Suzuki GSX-R1000 First Ride report. So much so that it quickly replaced it with its EVO designated successor. Although it appears the same as a standard R10 the EVO tire uses a revised structure and new compound blend designed to offer improved grip during acceleration, especially at high lean angles. The tire’s contact patch has been increased at lean angles in excess of 40 degrees and the compound formula now provides more road adhesion and does so at a wider range of track temperatures than before. The rear EVO is available in soft and medium compounds (Type 2 and Type 3) with us using the latter selection in OE sizes (180/55-17).

Compared to other popular brands the profile of the Battlax race tires proved to be compatible with each manufacturer’s machine, requiring minimal chassis set-up to get optimum handling performance from the motorcycle. Steering response is neutral yet precise and the tires offer plenty of feedback and road feel especially toward maximum lean. Flex characteristics was also favorable with it offering a good balance between that firm rigid feel under load yet still had a small degree of sidewall movement over bumps when loaded with the throttle or brakes.

Despite our testers not being totally sold on its mid corner handling the Honda posted very high average corner speeds.
The F3 feels light in the corner and has an incredibly accurate front end. With some fine tuning this bike could be a Supersport Shootout winner.
The Bridgestone Battlax R10s worked well with each motorcycle in the test requiring very minimal chassis set-up time to get the most out of. Grip was excellent, as was durability. We wouldn’t hesitate to line up on a race grid with these tires.
For optimum grip, wear characteristics and durability, Bridgestone recommends the tires be preheated to between 170 and 212 degrees before heading out on track. When done so they provide a very high-level of immediate grip. However, analysis of the tire’s temperature after our Superpole-style lap timing session showed that it does take a few laps for the R10s to arrive at operating temperature. In fact even in 115-degree heat the Battlaxs didn’t quite get to optimum temperature even after two flying laps at Chuckwalla. This isn’t a bad thing but it demonstrates how much heat the tire needs for maximum performance. It also shows how effective it can be especially in very hot conditions.

Consistency of grip and overall durability was another strong point with both tires recording in excess of 40 laps around Chuckwalla’s 2.68-mile road course before any signs of grip degradation were seen. In fact the only bike that could get the rear tire to move while picking up the bike off corner with the throttle pegged to the stop was the 120-plus horsepower GSX-R750 and even so it was nothing more than a small wiggle rather than real tire spin.
Bridgestone Battlax EVO Tire Pressure
Front (hot – off warmers): 32 psi
Rear (hot—off warmers): 28-29 psi
Front (hot—off track): 33-35 psi
Rear(hot—off track): 29-31 psi

All said and done it’s difficult to find any real complaints with Bridgestone’s latest road racing tires. They offer a neutral exterior profile that’s compatible with each manufacturer’s chassis. Handling response, road feel, grip and durability
Bridgestone Battlax R10 Highs & Lows
  • Very compatible with each brand's chassis
  • Neutral yet precise steering and handling
  • Excellent grip and durability
  • Tires require lots of heat to get maximum performance
were also excellent. Although you can’t buy a set of MotoGP slicks the R10 and R10 EVO are the next best thing and are a set of rubber we’d love to race on.

The Bridgestone Battlax R10 and R10 EVOs racing tires are available from Cycle Mall Race Tire Services (Phone no. 714 258-7501). All other Bridgestone road tires can be found at Motorcycle-Superstore.com

MSRP: $225 (front), $338 (rear)
2013 Middleweight Supersport Shootout
Class of 2013 - Supersport Shootout X.
Twenty years ago the Supersport class spawned a revolution in the sportbike world. Racing heroes the likes of Miguel Duhamel and the Hayden brothers had replicas of their race-winning bikes rolling off showrooms as fast as dealers could uncrate ‘em. The classic ‘win on Sunday, sell on Monday’ maxim was as heavy as the trophies these athletes hoisted. It was the heyday of sportbikes. A lot has changed since then, including the engine displacement as the class evolves, and while the popularity has cooled there are still riders who value apex strafing middleweight performance. It’s for those we present the track edition of our annual Supersport Shootout...

Correction (I race on R10's) Front tire is available in Soft (Type 4) and Medium (Type 3) compounds. The Soft compound was just release recently. The rear is only available in Medium and Hard compounds.

Just thought i would clear up a mistake in this above colum The Bridgestone R10 compounds are Type 4 is a Soft Compound Type 3 is a Medium Compound Type 2 is a Hard Compound Bridgestone Japan never recommend a hot presure off the warmers, they recommend a cold starting presure of 28PSI Front and 24PSI for the standard rear with and 26PSI for the EVO, with a goal of a 4-6PSI rise from cold to hot off the track These tyres are excellent for feedback and grip

Interesting that even with these grippy tires, the CBR600RR was the only bike that Jason Pridmore dragged pegs on during his "Superpole" laps.
