Bridgestone Battlax Adventure Trail AT41 Front Motorcycle Tire 90/90-21 54V

The Bridgestone Battlax Adventure Trail AT41 Front Motorcycle Tire 90/90-21 54V is a bias-construction front tire built in Japan for adventure riders who spend most of their time on pavement but still want to handle the occasional dirt detour. Bridgestone rates it at an 80 percent on-road and 20 percent off-road split, so it leans toward touring comfort and wet-weather grip while keeping enough tread aggression for light off-road use. The groove layout is optimized for water drainage, wet braking, and traction on pavement, and Bridgestone's MS Belt technology works alongside the block pattern to promote stability.

This is a front tire in size 90/90-21, where 90 is the section width in millimetres, 90 is the aspect ratio as a percentage of that width, and 21 is the rim diameter in inches. The rim diameter must match your wheel, and the full size code should match what is printed on the sidewall of the tire you are replacing. It carries a load index of 54 and a V speed rating, which covers speeds up to 149 mph (240 km/h). Your machine's own specification determines the correct size, load index, and speed rating.
