Direct-Fit Pin for KE25SP Units

The Kyosho 74032-06 piston pin is produced to match KE25SP internal geometry, giving a reliable connection between piston and conrod. Its role is to keep the piston centered and moving smoothly during engine cycles.

Precision Machining for Stable Travel

With close machining tolerances, this pin reduces unwanted play and helps preserve piston and bore condition. Regular inspection during tune-ups will reveal any early wear before it affects performance.

Easy Replacement for Hobby Tuners

As a part tailored for KE25SP engines, the pin installs without modification and suits model builders who prefer keeping original engine specifications intact.
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 the 74032-06 affect piston clearance?

If fitted correctly, the pin maintains designed piston clearance. Always verify ring and piston fit after installation to confirm clearances are within spec.

Can I reuse a pin when rebuilding an engine?

Reusing is possible if the pin shows no scoring or deformation, but best practice is to replace it during a rebuild to ensure long term reliability.

What lubricant should I use on assembly?

Use a light assembly oil or recommended engine lubricant on the pin and small end bore to aid initial break-in and prevent dry starts.

Are aftermarket upgrades needed with this pin?

For standard KE25SP rebuilds the OEM-style Kyosho 74032-06 is sufficient; performance upgrades focus more on ports, carburetion and exhaust rather than the wrist pin itself.
