PISTON KIT KTM350 EXC-F 88mm A, WOSSNER 8941DA COMP 12.5:1 79230507000

The Wossner 8941DA piston kit is a forged, high-performance component engineered for precision and durability in 4-stroke off-road motorcycles. Designed with an 88.00mm standard bore and a compression ratio of 12.5:1, it ensures efficient heat transfer and optimal combustion. Manufactured in Germany, the piston’s elliptical design supports uniform expansion under thermal stress, preventing localised pressure points and piston failure.
