Description
The wrist pin is a critical connecting component that transfers combustion forces from the piston to the connecting rod—when it fails, your engine fails. The Wiseco S477 is engineered to handle the extreme pressures and temperatures of high-revving two-stroke engines, delivering the precision fit and material integrity that separates reliable power from catastrophic failure. If you're rebuilding a KTM 300 EXC or pushing its limits on the trail, this is the part that keeps your engine together.
Wiseco's manufacturing process minimizes tolerance stack-up and thermal expansion, which means consistent piston-to-rod geometry under load. You get a wrist pin that won't develop play, won't seize, and won't surprise you mid-ride.
