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.

Is special preparation required before fitting?

No special preparation beyond cleaning the mating surfaces and checking the ring gear is needed. Ensure correct mesh and secure mounting hardware during installation.

Will this gear affect motor load?

When correctly meshed with the matching ring gear, the drive gear should not add significant extra load. Proper setup keeps motor load within expected ranges for your existing gearing.

What signs indicate gear wear?

Look for rounded or chipped teeth, increased noise, or slipping under throttle. Any of these signs mean the gear should be replaced to avoid further drivetrain damage.
