Bridgestone just presented the new street legal race tyre Bridgestone R11 designed to give supersport and hypersport riders the confidence on track to slash their lap times.
With an awesome mix of Bridgestone technology cultivated at the highest level of motorcycle racing, combined with advanced new compound and construction features, R11 delivers the highest performance in the grooved racing tyre segment. And all this without compromising Bridgestone’s racing DNA on consistency.
Nico Thuy, Head of Europe - Motorcycle, Bridgestone Europe sums up: “Racing is all about confidence. With the new Battlax Racing R11, Bridgestone gives competitors that extra grip and contact feel on the track, particularly going into corners where confidence is so important. R11 riders will see their lap times improve from the start!”
Feel the performance
To develop R11, Bridgestone took the current Battlax Racing R10 as the benchmark and set sights on enhancing the contact feel of the track as the tyre performs, allowing the rider to attack lap time records during the race, lap after lap, in a large operating range.
Grip on braking and acceleration
The R11 package is based on a new variable mono-spiral belt (V-MSB) construction in the front tyre, which produces higher pressure on the contact patch and more cornering force. This gives the rider better grip and faster corner entry, with more contact feel, and therefore more confidence.
The rear tyre construction uses an additional GP belt (proven in the Bridgestone V02 racing slick) on top of the V-MSB which is tuned for optimal deformation. The result is a rear tyre with higher traction power, consistent performance over the tyre life and more grip in all phases.
Moving to the tread design, Bridgestone engineers first analysed the abrasion angle under acceleration and deformation in the braking and cornering phases. This enabled them to develop innovative groove positioning for R11 which provides maximum rigidity in cornering and maximum contact in the acceleration phase, while ensuring optimal deformation for improved warm up times.
Faster lap times
Track testing2 shows marked improvement versus predecessor in all areas, especially in the main target area of corner entry, for extra confidence. This impacted on lap times, giving R11 consistently faster laps with a 1.3% improvement on fastest lap.
The new Battlax Racing R11 is recommended for all motorcycle racing categories including SSP 300, SSP 600 and SST 1000 championship series, as well as all manufacturers’ cup events.
Bridgestone will introduce a full line-up of 2 front sizes and 6 rear sizes from January to March 2018. All R11 sizes will be available in medium compound with a soft option available in certain sizes.
Bridgestone went to Spain between 3 and 7 October 2017 to launch Battlax Racing R11, its newest race tyre. Key dealers and media from all over Europe gathered to put Battlax Racing R11 to the test on the famous Monteblanco race track and celebrate its performances
