Drivetrain Upgrade for YZ-4S

The Yokomo S4-SG80CDA 80T spur gear is a compact upgrade for owners who want consistent centre differential behaviour in their YZ-4S. The 48 pitch teeth are engineered to keep gear mesh tidy while transferring power efficiently. Suited to practice sessions and competitive outings, this spur helps preserve smooth drivetrain response.

Feature Highlights for the 80 Tooth Spur

  • Tooth Count: 80T provides a balanced approach to torque delivery and controllable speed.
  • Pitch: 48 pitch ensures compatibility with standard YZ-4S gearing arrangements.
  • Compatibility: Intended for YZ-4S variants including B-YZ4SF / B-YZ4SF2-1 / MOR-010 / MOR-020.
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 I swap this into an older YZ-4S version?

It is made for the YZ-4S family listed above; older variants that share the same center diff dimensions and 48 pitch may accept it, but check fitment first.

Does the 48 pitch require special pinions?

Use pinions and mating gears that match 48 pitch to ensure correct mesh and minimise wear on the drivetrain.

How often should I inspect the spur?

Check the spur for wear and correct mesh after several runs or if you notice vibration; keeping gears clean will extend life.
