Bridgestone Battlecross E50 Front Motorcycle Tire 90/90-21 54P

The Bridgestone Battlecross E50 Front Motorcycle Tire 90/90-21 54P is a bias-construction front tire built specifically for hardcore enduro riding and a broad range of off-road conditions. Bridgestone developed it with Castle Block™ technology, increased block rigidity, and what they call bunker technology to add biting edges and improve traction on dirt. The sidewall rigidity and profile have been tuned so the tire seats on the rim more easily at the track or on the trail. It is made in Japan.

The size code 90/90-21 breaks down as 90 mm section width, an aspect ratio of 90 percent of that width, and a 21-inch rim diameter. That 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 54 and a P speed rating, which covers speeds up to 93 mph; both values need to meet or exceed what your machine's specification calls for.
