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. Features include forged piston construction for enhanced strength, optimised combustion heat transfer to cylinder walls, and an elliptical shape for even pressure distribution and thrust load balance, designed to prevent piston collapse. This kit includes piston, rings (880XSY), pin (WP054), and circlips (CW18). Specifications: Bore: 88.00mm (STD), Diameter: 87.95mm, Compression Ratio: 12.5:1, Wossner Part Number: 8941DA, Kit Part Number: 56-W9950.A.WO. Made in Germany. Cross-reference OEM Part Numbers: 79230507000, 40166M08800.
