Tune with a 91T 64-pitch spur

The 91-tooth spur provides a precision alternative for 64-pitch RC drivetrains. Its accurate tooth profile helps reduce meshing inefficiencies and promotes consistent power delivery in model car geartrains.

Use a matching 64-pitch pinion to keep correct tooth engagement. During setup, confirm the pinion-to-spur mesh, establish a proper backlash setting, and check for uniform contact across the tooth face to minimise wear.

Choosing 91T in tuning gives you finer gradations of final drive ratio than smaller spurs, allowing small steps to adjust acceleration and top speed without changing other drivetrain elements.

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 switching to 91T affect acceleration or top speed?

Yes. The 91T count allows finer ratio steps so you can make small changes that influence acceleration versus top-end performance without altering other drivetrain parts.

How can I verify alignment and mesh under load?

Run the drivetrain slowly under load, observe contact across the tooth face, confirm parallel shafts, and adjust backlash until contact is even during rotation.
