Upgrade YZ-834B Rear Drive with the Yokomo ZB-503I20

The Yokomo ZB-503I20 is a 20-tooth idler gear intended for the YZ-834B Dog Fighter rear drivetrain. It supports steady power transfer by preserving correct gear engagement and reducing drivetrain slop. Built for repeated setup adjustments, it suits drivers who regularly check gear mesh and drivetrain behaviour.
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.

What role does this idler play in handling?

By keeping the gear mesh consistent, the idler helps the drivetrain react predictably under load, which can make throttle response smoother on acceleration and deceleration.

Can I use aftermarket bearings with this gear?

If the chassis location accepts different bearings, upgrades can reduce friction; verify fitment and clearances before swapping components.

Does the ZB-503I20 need a break-in period?

A short period of light running and checking mesh is sensible after installation to confirm smooth operation and to spot any early wear or alignment issues.
