Unlock elite-level power and throttle response with the Wossner 4092DA Piston Kit. Specifically engineered for the latest generation of Yamaha's flagship motocrosser, this gas-ported, two-ring design is built for racers who demand maximum ring seal and reduced internal friction. At Moto-House MX, we provide the high-performance engine components necessary to keep your YZ450F at the front of the pack.

This "Standard Size A" piston is forged from aerospace-grade aluminum alloy, utilizing a double-bridge forging and 3D crown for incredible structural integrity. The gas-ported design uses combustion pressure to push the rings against the cylinder wall, ensuring a superior seal compared to standard pistons. Combined with a permanent anti-friction skirt coating, this kit delivers quiet, smooth performance and optimized lightness without sacrificing strength in the crown or skirt wall cross-sections.
