PISTON KIT 90-94 KTM250 68.50, WOSSNER 8005D100 FORGED
Wossner Forged Piston Kit 68.50mm Bore – KTM GS250 / SX250 (1990–1994)
This Wossner forged piston kit is specifically engineered for KTM GS250 and SX250 models from 1990 to 1994. Featuring a 68.50 mm bore and a piston diameter of 68.44 mm (+1.00 mm oversize), it is ideal for 2-stroke engine setups requiring increased performance and structural reliability. The piston’s forged design ensures superior strength, while the elliptical geometry improves load distribution and reduces localised pressure under thermal expansion. Manufactured in Germany with precision standards.
Features
-
Forged piston construction for exceptional strength and longevity
-
Optimised design for effective heat dissipation to the cylinder walls
