Thoughts from the development engineer

Motorcycle Tire Development division, Development Unit 2,
Kensuke Dobashi

When we were developing the BATTLAX RACING STREET RS10, our aim was to re-establish Bridgestone's existing ideas about the right way to create a tire. We were seeking not only the existing feature of "BATTLAX = high grip" but also an enhanced "contact feel" that you notice as soon as you ride the bike. We wanted to sweep away the fixed image that high-grip tires are only for advanced riders.
Our aim was for everybody who got on the bike to straight away have this sense of surprise and delight. We developed the tire with a goal in mind of creating something that allows more people to enjoy biking life.

Also, I think that pattern design is an important factor to decide bike’s characteristics. It's a major contributor to the sense of owner’s satisfaction that a rider feels when the bike is fitted with attractive tires.
High-grip tires inevitably have fewer grooves and they tend to resemble each other, because the assumption is always that function must drive the pattern design. With the BATTLAX RACING STREET RS10 we paid a lot of attention to the visual appeal of the tire and tried to create an elegant, high-quality pattern design. We wanted the choice of tire to enable you to make your machine look even more beautiful, enhancing the joy of bike ownership.

We ran repeated tests with all levels of riders, from near-beginners to those with advanced skills. Needless to say we tested in all kinds of environments, not only in Japan but also overseas, on public roads and on race tracks. To achieve this unprecedented riding feelings, we approached the development from various angles, considering not only the rubber used in the tread, but also the internal construction of the tire, the overall balance of the tire and so on. I would really like you to try this unique new tire for yourself, to evaluate it in the context of your own riding style.

New tread pattern

The New tread pattern is adopted to the RS10. Using a "3D" groove shape we increased the rigidity of the blocks and this resulted in improved stability when braking and accelerating. We aligned the grooves with the direction of the steering inputs when cornering, which leads to more rigid blocks. Furthermore, by creating standalone grooves on the shoulder of the tire, we allowed the tread to deform more easily so that the tire can warm up more quickly.
By using this new tread pattern we improved the stiffness of the pattern by 6% at the front and 16% at the rear.

  1. We aligned the grooves with the direction of the steering inputs when cornering, leading to more rigid blocks.

    Through the use of a 3D groove shape we made the blocks more rigid and improved stability when braking and accelerating.

  2. By adding standalone grooves we allowed the tread to deform more easily, making shorter warm-up times possible.

New compound and optimized shape (rear tire)

Through the adoption of a new compound we further improved grip in the high temperature zone.
By increasing the crown radius of the shoulder area we enlarged the size of the contact area at camber and this leads to improved stability during turns.

Dry grip and handling performance suitable for a premium road tire

The new tire surpasses the BT-003 ST in all 6 areas (grip, front and rear; contact feel, front and rear; handling; overall score) and led to a 1.5 second reduction in lap times at the Autopolis circuit.*
