What is a rim lock on a dirt bike?

A rim lock on a Dirt Bike is a device mounted on the wheel's rim to prevent the tire from spinning on the rim under heavy braking or when riding off-road. It consists of a metal clamp or ring that is positioned between the rim and the tire. The rim lock is tightened to grip the rim tightly, ensuring that the tire stays in place during aggressive acceleration or braking. This helps to improve traction and control, especially on uneven terrain or when riding in challenging off-road conditions. Rim locks are commonly used on dirt bikes to enhance performance and prevent tire slippage.
