What Happened
Bridgestone Corporation announced the BATTLAX ADVENTURE A42, an adventure-category motorcycle tire launching on January 1, 2027, in an announcement dated October 22, 2026 in Tokyo. The tire is built under the concept "The answer to the road going Adventurers" and targets adventure riders who primarily ride on-road. Bridgestone says it delivers the best balance of safety, peace of mind, economy and comfort from city streets to expressways and winding roads. It aims to combine wet performance and wear life at a high level while reducing tire noise when riding, supporting comfortable long-distance touring.
- 14% lower than the previous model
- 18% improvement
- 25% improvement
- New compound: the front tire uses a flexible polymer to enhance road-surface tracking, while the rear tire uses a polymer that improves wear resistance.
- Silica and carbon content are optimized separately for the front and rear to balance wet performance and wear life.
- New pattern design inherits the design lineage of the latest BATTLAX lineup, described as aggressive yet refined and suited to adventure motorcycles.
- Pulse Groove technology enhances water drainage, and a revised groove layout optimizes pattern stiffness to improve the balance of wet performance, wear life and quietness.

Bridgestone cites aggregated TYRES EUROPE data; on-road riders make up the majority of this market, with strong demand for wet performance, wear resistance and comfort.
Bridgestone announces the BATTLAX ADVENTURE A42 from Tokyo.
Sequential launch in countries worldwide, starting with 6 sizes: 3 front and 3 rear.
Japan domestic launch is planned.
The lineup expands to 9 sizes: 4 front and 5 rear.
Bridgestone says the tire addresses European demand for peace of mind in sudden rain, economy through longer wear life and comfort on long tours. Beyond the 14% lower slip ratio and the 18% front and 25% rear wear-life gains, it reduces tire noise by 15% compared with the previous model. The predecessor A41 was well received as an adventure tire designed primarily for on-road riding, and Bridgestone says the A42 retains those strengths while improving wet performance, wear life and noise reduction. Bridgestone adds that the results are based on test data and may vary depending on riding style.
Previously from Bridgestone Corporation
Bridgestone's BATTLAX name is already established in motorcycle racing and as factory equipment. In September 2026, the BMW MOTORRAD WORLD ENDURANCE TEAM won the 2026 FIM Endurance World Championship on Bridgestone's BATTLAX tires, the first time a European manufacturer has taken the title. Earlier that month, Kawasaki's new flagship Ninja ZX-10R was announced as coming from the factory with Bridgestone's BATTLAX RACING STREET RS12 tire.

Why this matters
Adventure motorcycles are sold as do-everything bikes, and in Europe — the market Bridgestone cites — tire demand in the category has grown 45% over the past decade. Most of those riders stay on-road, so grip in sudden rain, longer wear and lower noise directly affect buyers' cost and comfort. The launch extends Bridgestone's premium BATTLAX lineup into that growing segment.
Terms in This Story
- Pulse Groove
- A tread groove design that uses a pulsating pattern and deflectors to even out water flow and speed it through the grooves, improving drainage; it is used in passenger car and motorcycle tires.
- Compound
- The rubber mixture a tire is made from; changing the polymers used and the silica and carbon content alters properties such as grip and wear resistance.
