Race-Ready Sprockets for YZ-834B Chassis

The Yokomo ZB-630 Sprocket Set offers 12T and 13T gears for straightforward gear ratio tuning on the YZ-834B chassis. Select the smaller or larger sprocket to shift the balance between acceleration and top speed, taking into account motor and battery performance. Manufactured to fit YZ-834B mounting geometry, these sprockets aim to maintain consistent drivetrain engagement during active running.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will aftermarket transmissions accept these sprockets

They are designed to the YZ-834B standard. Aftermarket transmissions may fit but you should confirm shaft sizes and mounting hole layouts before assuming interchangeability.

Does changing sprocket size affect motor load and battery life

Yes, lowering the gear ratio with a smaller sprocket increases motor RPM and can raise current draw, while a larger sprocket can reduce load but may demand more from top-end performance.

How often should I check sprocket condition

Inspect sprockets after heavy sessions and at regular service intervals. Look for hooked or rounded teeth and replace parts showing visible wear to protect chain and gearbox gears.
