Wossner 8608DA Piston Kit - 2005-2017 Honda CRF450X / 2005-2008 CRF450R Size A

Wossner 8608DA Premium Series Forged 4-Stroke Piston Kit - Standard Size A

Refresh the heart of your Honda 450 with the Wossner 8608DA Piston Kit. Specifically engineered for the legendary 2005-2017 Honda CRF450X and the 2005-2008 CRF450R, this Premium Series forged kit is the professional choice for restoring "Factory Quality" power and reliability. At Moto-House MX, we know these Unicam engines are the workhorses of the trail and track; Wossner’s aerospace-grade forged components provide the precision fitment needed to keep your machine performing at its peak.

Forged from aerospace-grade aluminum alloy, the 8608DA maintains a reliable 12.0:1 compression ratio, providing smooth power delivery and excellent durability for long-distance off-road riding. Wossner incorporates advanced features like radial boss machining and enhanced oiling slots for superior wrist pin lubrication—a critical upgrade for the high-temperature environments these 450cc engines often face. The permanent skirt coating minimizes internal friction and piston rock, resulting in a quieter engine and a more efficient break-in. This Standard Size A piston (95.96mm) is precision-matched for 96.00mm bores, perfect for a top-end refresh that restores your Honda to its original factory tolerances.

Top Features: Wossner 8608DA Piston Kit

• 12.0:1 Compression Ratio: Matches original specifications for reliable, consistent power and compatibility with premium pump fuel.
• Premium Series Forging: Significantly stronger and more heat-resistant than OEM cast pistons, ideal for the high-load demands of enduro and motocross.
• Enhanced Lubrication Design: Radial boss machining and annular grooves ensure the wrist pin stays lubricated during intense, high-RPM operation.

Expert Pro-Tip: The CRF450X and early CRF450R are known for their incredible longevity when properly maintained. When performing a rebuild with the 8608DA, we strongly recommend inspecting your valve train and replacing your cam chain. Size A is the ideal choice for a cylinder that is still within factory service limits. Always use a fresh top-end gasket kit and high-quality synthetic oil to ensure a professional-grade seal and protect your new forged assembly.
