A low-friction replacement front drive belt for Yokomo BD7 and BD5 series chassis. The BD-516L uses a softer compound than standard belts to cut drag in the front drivetrain. It is supplied as a single unit for 1/10 on-road cars where drivetrain efficiency affects setup decisions and front-end behaviour.
Compatibility and fitting: the belt installs along the factory belt route on supported BD7/BD5 variants. Follow your chassis disassembly routine to fit, then verify tracking and tension before running. The compliant material will respond differently from stock belts, so adjust tension to prevent slip while keeping minimal preload.
