PISTON KIT 01-08 KTM50 SX, WOSSNER 8225DC FORGED MX

Wossner Forged Piston Kit 39.52mm Oversize for KTM 50cc

Upgrade your KTM 50cc engine with this high-performance Wossner forged piston kit. Engineered for durability and optimal power delivery, this kit is designed for a 39.52mm bore, representing a +0.02mm oversize from the standard size. It is meticulously crafted in Germany to meet the demanding requirements of high-revving two-stroke motocross engines.

This Wossner piston features a precision-machined elliptical profile. This advanced design ensures even load distribution across the piston's surface, significantly reducing stress concentrations and preventing piston collapse under extreme operating conditions. The forged construction provides superior strength and resilience compared to cast pistons, leading to enhanced longevity and consistent performance, especially during demanding rebuilds where minimal oversizing is required.

Key Features:

• Forged Construction: Provides exceptional strength, durability, and resistance to wear for extended engine life.
• Elliptical Piston Profile: Designed for optimised load distribution, stress reduction, and prevention of piston collapse.
• Efficient Heat Transfer: Engineered to effectively dissipate heat from the combustion chamber to the cylinder walls, maintaining optimal operating temperatures.
• Precision Manufacturing: Made in Germany to exacting standards for superior quality and reliability.
• Oversize Application: Specifically sized at 39.52mm (+0.02mm) for engines requiring a slight bore increase during rebuilds.
