Bridgestone Corporation (Bridgestone) has announced the launch of BATTLAX ADVENTURE A42, an adventure motorcycle tire that will become available sequentially in countries worldwide starting Jan. 1, 2027¹. Under the concept of “the answer to the road-going adventurers”, the BATTLAX ADVENTURE A42 is designed to deliver an excellent balance of peace of mind, economy and comfort for adventure riders who primarily ride on-road. From city streets to expressways and winding roads, the tire achieves an optimal balance of wet performance and wear life while helping reduce tire noise while riding, supporting comfortable long-distance touring.

Improving a Proven Foundation

Adventure motorcycles are recognized for their versatility, ranging from urban riding to long-distance travel. In the European market, demand for tires in this category has increased by 45% over the past decade².

Bridgestone launched the BATTLAX ADVENTURE A41 in December 2017 to address the primary needs of riders in this growing segment, including strong wet performance during sudden rainfall, improved wear resistance and comfort on long-distance journeys. Building on its predecessor’s proven foundation, the BATTLAX ADVENTURE A42 further supports these essential riding needs by delivering improvements in each area:

Enhanced Wet Performance: The BATTLAX A42 reduces tire slip ratio under straight-line acceleration by 14% compared to the previous model3, contributing to stable riding even in rain.
Extended Wear Life: The new BATTLAX A42 delivers longer wear life than its predecessor at both tire positions, with 18% longer life at the front and 25% longer life at the rear³.
Reduced Tire Noise: With a larger contact patch, the new BATTLAX A42 tire is designed to deliver greater riding stability and comfort. In internal testing, it reduced tire noise by 15% compared to the previous model³.

Engineering and Technological Advancements

The new Bridgestone BATTLAX ADVENTURE A42 road adventure tire achieved improved performance over its predecessor thanks to new tread compounds, an adventure-inspired tread pattern, and optimized construction. The upgraded tire construction leverages the core details of the BATTLAX lineup while incorporating new materials and design choices tailored for road-oriented adventure bikes.

Optimized Compound Formula: The front tire compound of the BATTLAX A42 uses a flexible polymer to improve road-surface grip, while the rear compound uses a polymer that enhances wear resistance and mileage. Both compounds include optimized silica and carbon content that achieves a high level of balance between wet performance and tire life.
New Pattern Design: Inheriting the design lineage of the latest BATTLAX lineup⁴, the tire features an aggressive yet refined new tread pattern suited to adventure motorcycles. In addition to incorporating Pulse Groove water drainage technology⁵, the tire boosts pattern stiffness through a revised groove layout to improve the overall balance of wet performance, wear life and quietness.
