PISTON KIT 04-07 KTM300 72.00, WOSSNER 8219DB FORGED
This Wossner 8219DB piston kit features a 72.01mm bore, which is a +0.01mm oversize from standard. It is designed for KTM 300cc two-stroke engines and has a forged construction for enhanced durability and optimal thermal performance in off-road applications. The +0.01mm oversize forged piston provides an improved fit in slightly worn cylinders and is engineered for efficient heat transfer from the combustion chamber to cylinder walls. It has an elliptical design for uniform bearing surface under thermal expansion, preventing localized pressure points and piston collapse. This piston kit is manufactured in Germany. Specifications include a bore diameter of 72.01 mm, display displacement of 293 cm³, stroke of 72.00 mm, clearance of 0.06 mm, and a 2-stroke compression ratio (Wossner and OEM specification). The compression height is 38.00 mm. Included components are piston kit part number 56-W858.B.WO, two rings (RSB7200), one circlip (CW18), one wrist pin (WP033), one gasket (D2024-EST), and one connecting rod (P2023).
