Bridgestone Launches BATTLAX CLASSIC RACING CR11 Motorcycle Tires for Classic Bike Race
TOKYO (January 28, 2020) -- Bridgestone Corporation (Bridgestone) announced the launch of the BATTLAX CLASSIC RACING CR11 motorcycle tires for classic bike races. BATTLAX CLASSIC RACING CR11 tires will be available in one front tire size and one rear tire size when released in each market starting in February 2020. These tires use racing specifications and are designated NHS (Not for Highway Service)*1 and therefore cannot be used on public roads.
A form of motorcycle racing popular largely in Europe, classic bike races use older vehicles from the 1980s. BATTLAX CLASSIC RACING CR11 tires are a direct line of RACING BATTLAX tires that utilize the technologies Bridgestone has cultivated over years of developing tires for motorcycle races. These tires feature an optimized pattern design and compound based on BATTLAX RACING R11 circuit racing motorcycle tires to realize both the high grip and the superior stability required in classic bike races.
1. Pattern Design
BATTLAX CLASSIC RACING CR11 tires use a pattern design based on BATTLAX RACING R11 tires to realize improvements in cornering grip and water drainage when turning.
Both front and rear tires use a racing-purpose compound that emphasizes grip.
3. Innovative V-MS・BELT Construction
The innovative V-MS・BELT (Variable pitch-Mono Spiral Belt) construction features a circumferential-direction distribution of steel cords that differs based on the tread position. Employing this construction greatly improves the contact properties of the tire and contributes to a more even contact pressure distribution. This structure allows for more efficient contact between the tire and the road surface for increased grip. In addition, Bridgestone's ULTIMAT EYE™ technology*2 was utilized in the optimization of the V-MS・BELT construction.
