Product Details
The Bridgestone Motocross M403 (front) and M404 (rear) are purpose-built youth motocross tires for 50cc, 65cc, and 85cc minicross bikes, rated by Bridgestone for hard-to-medium terrain. They replaced Bridgestone's earlier M401/M402 minicross line, carrying over tread design and rubber compound development from Bridgestone's SX/MX and off-road factory racing program. The M403 front is tuned for bite, cornering control, and steering feedback at full lean angle, while the M404 rear is built for traction and slide control under hard corner-exit acceleration. Both are bias-ply, tube-type competition tires intended for closed-course/off-road motocross use only, not for public roads.
