Refine OPTIMA Mid drivetrain with Kyosho OT257

Serious modelers seeking a tighter drivetrain will appreciate the OT257 counter gear set by Kyosho, engineered to suit the OPTIMA Mid platform. It helps deliver predictable torque transfer and reduces drivetrain lash under load.

Precision engineering for consistent performance

The Kyosho OT257 is manufactured to close tolerances to minimise slop between mating gears. That accurate fit lowers vibration and supports consistent throttle response during competitive running.

Designed for regular track use

This counter gear set is aimed at drivers who log many practice laps and need components that resist the usual wear points. Routine checks after running will keep the gearbox in top shape.
Remark :
Due to limited stock availability, please notice that some Kyosho 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 the OT257 compatible with modified OPTIMA Mid setups?

The OT257 is compatible with many OPTIMA Mid configurations, but if you run nonstandard spurs or altered gear spacing you should verify clearance and mesh before prolonged use.

What materials are used in this gear set?

Kyosho produces these components from hardened materials suited to gearbox duty. The result is improved wear resistance compared with lower grade alternatives.

Will fitment change my gear ratio?

The OT257 is a like-for-like counter gear set so it should not alter overall gear ratio when fitted as intended. Always confirm final gear ratio after installation.

How do I check gear mesh correctly?

Set a small amount of backlash by moving the pinion slightly, then run the drivetrain by hand to feel for smooth engagement. Fine tune with thin shims if needed.
