Battlax Sport Touring T30 EVO
The T30 EVO was developed in response to the growing number of motorcyclists who want a touring tire that offers them the peace of mind of consistent and comfortable performance on wet and dry surfaces – yet still gives them plenty of sporty handling and fun. The technical aim for Bridgestone was therefore to maintain T30’s superb dry performance while upgrading its wet performance.
Wet performance has been transformed by the development of new formula compounds that increase friction on wet surfaces. A new compound applied to the front tire in combination with a newly-developed compound on the center strip of the rear tire improve wet performance without sacrificing dry performance, and over a wider temperature operating range, as well as provide more stability, particularly for heavy-loaded touring bikes.
The other part of the equation is the T30 EVO tread design. The rear pattern has been re-engineered with sub-grooves extending to the center strip which increases water channeling away from the contact patch, giving riders more traction in wet conditions. At the same time, the curved grooves have been moved outward to create a rib along the center strip, adding stiffness to the tread for stability when accelerating. This change also increases the size of the contact area with the lean angle, adding more grip and enabling the rider to corner in greater safety.

Battlax Adventure A40
By fusing the MotoGP™ heritage of the Battlax brand with the proven performance of Battle Wing, Bridgestone has created an Adventure tire that delivers enhanced traction and stability, particularly on wet surfaces, and greater durability.
The goal of Bridgestone engineers was to significantly improve Battle Wing’s dry and wet handling – without sacrificing its high-level stability and durability – giving adventure bikers greater pleasure and safety on all roads and in all conditions.
This has been achieved with Battlax Adventure A40 by improving dry handling without loss of stability: a new front tire profile produces a larger contact area at high lean angles for better cornering grip; larger tread blocks add stiffness for more cornering stability; and Bridgestone’s mono-spiral belt construction on the front tire improves shock absorption, for greater rider comfort and less fatigue.
Wet performance has been improved by the revised compound incorporating Bridgestone’s proprietary NanoPro-Tech technology which helps reduce heat generation caused by tire deformation.
At the same time, Bridgestone has re-engineered the A40 tread patterns to upgrade wet performance and stability. By re-designing the groove angles and layout on the front tread pattern, cornering stability has been enhanced. Wider grooves on front and rear improve water clearance and upgrade wet performance. The layout of the grooves on the rear tire facilitates larger blocks, for added stiffness, which provides more stability during cornering.
