Wiseco Piston Kit with Gasket, 3.740 in Bore for Husaberg, Husqvarna and KTM (PK1901)

The Wiseco PK1901 Piston Kit with Gasket is a complete top-end replacement solution for select Husaberg, Husqvarna and KTM engines. Designed for a straightforward rebuild, this kit includes the essential piston components and gasket materials needed to service one complete engine. The 3.740-inch bore size supports accurate fitment when matched to the correct engine application and cylinder configuration.
The kit includes a Wiseco piston, piston rings, wrist pins, circlips and a top-end gasket kit. These components are supplied together to help simplify installation and ensure the key parts required for a piston replacement are available in one package. Always verify engine specifications and application compatibility before installation, including the required Wiseco ring type and cylinder condition.
Wiseco ring types are application-specific and are not interchangeable. For example, CD rings must not be substituted for LC rings, and the piston must be fitted only with the correct Wiseco rings specified for the application. Cylinder sleeves are not included and must be purchased separately when required. Follow the manufacturer's installation procedures, confirm all clearances and use the appropriate service information for the engine being rebuilt.
