Tune Your YZ-834B Drivetrain

The Yokomo ZB-630 Sprocket Set gives YZ-834B operators two tooth-count options, 12T and 13T, so you can tailor the drivetrain response to track conditions. Swapping sprockets alters the gear ratio and helps you prioritise either quicker roll-out or improved top-end speed. The parts are produced to match YZ-834B mounting points and provide reliable mesh under race loads.
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.

Can older YZ-834B variants use these sprockets

They are intended for YZ-834B specification. If you run an older or modified variant, verify sprocket spacing and shaft dimensions before fitting.

Which sprocket suits tight technical layouts

The 12T option favours quicker acceleration out of tight bends, making it a common choice for technical, stop start tracks where initial roll is key.

Do I need a different chain or belt when changing sprockets

Most standard YZ-834B chains match the ZB-630 sprockets, but check pitch and wear. Replace any stretched or worn chain to maintain proper engagement and prevent skipping.
