The Yokomo B10-630OA aluminium outer drive pulley is machined to support BD10 chassis builds. With a 20-tooth profile it spreads belt load more evenly and the treated surface reduces friction for steadier running and better durability.
Compact and resilient, this pulley is compatible with Yokomo models such as MRTC-BD10FF, MSR-BDFWD and MSR-010 series. It is a practical part for racers and tuners seeking a reliable drivetrain improvement.
