Bridgestone Battlecross X31 Front Motorcycle Tire 80/100-21 51M

The Bridgestone Battlecross X31 Front Motorcycle Tire 80/100-21 51M is a bias-construction off-road front tire made in Japan and built around Bridgestone's Bunker Groove technology, which increases casing flex in the tread area for better lug contact on rough and soft terrain. Bridgestone designed it to maintain grip across changing weather conditions. It is not certified for use on public roads.

The size code 80/100-21 tells you the tire has an 80 mm section width, an aspect ratio of 100 percent of that width, and fits a 21-inch rim. The rim diameter must match your wheel exactly, and the full size code should match what is printed on the sidewall of the tire you are replacing. This tire carries a load index of 51 and a speed rating of M, which covers speeds up to 81 mph (130 km/h). Your machine's specification determines which load index and speed rating are required.
