Description
If you’re running a stock 125cc two-stroke, you’re leaving performance on the table. A Wiseco piston kit opens the door to measurable gains in power and throttle response while maintaining the reliability your bike demands. Whether you’re rebuilding after wear or chasing an edge on the track, this oversize piston delivers the precision and durability that serious riders depend on.
The 56.00mm oversize bore increases displacement by 2.00mm, translating to improved combustion efficiency and more usable power throughout the RPM range. Wiseco’s engineering ensures a tight tolerance fit that minimizes blowby and maximizes heat transfer away from the ring lands. The lightweight construction keeps rotational mass in check, allowing your engine to rev more freely and respond crisper to throttle input.
Note: This kit does not include a gasket set. Source your gaskets separately to complete the job properly.
