Tune the OPTIMA Mid with Kyosho OT257 counter gears

For builders who refine drivetrains, the OT257 counter gear set from Kyosho is made to pair with the OPTIMA Mid chassis and reduce sloppy gear meshing. Its careful engineering helps keep power transfer smooth while extending service intervals for regular club racers.

Built for steady power transfer

The Kyosho OT257 uses durable materials and tight tolerances to reduce play and cut down on wear in the gearbox. It installs cleanly into the OPTIMA Mid layout and is a practical choice for hobbyists chasing consistent lap times.

Durability that handles frequent running

Whether you are running practice sessions or weekend races, this counter gear set gives extra resilience where drivetrains see the most stress. That means fewer gearbox rebuilds and more track time between maintenance.
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.

Will OT257 fit without modding the OPTIMA Mid gearbox?

The OT257 is produced to match OPTIMA Mid specifications so it should install without major modifications. Check clearances and mesh during fitting to ensure proper engagement.

What maintenance should I plan after installing this gear set?

Inspect gear mesh and bearings after the first few runs, retighten fasteners, and recheck lubrication points. Regular checks will catch wear before it affects performance.

Can I use stock pinion and spur with this gear set?

In most cases the stock pinion and spur mesh fine with the OT257, but confirm the pinion alignment and backlash to avoid premature wear.
