JE Pistons Yamaha YFZ 450 Piston Single

This is a JE Pistons forged single piston for your Yamaha YFZ 450. JE Pistons is a well-known name in high-performance engine components, and this piston is built to handle the demands of a performance ATV engine. If you're rebuilding the top end of your YFZ 450 or looking to upgrade for more power, a strong piston is a critical piece of the puzzle.

Forged pistons, like this one from JE Pistons, start as a solid block of aluminum that's heated and hammered into shape under immense pressure. This process creates a much denser, stronger, and more durable piston than cast pistons, which are made by pouring molten aluminum into a mold. This improved strength means the piston can better withstand the higher compression ratios and increased combustion pressures often found in modified or performance-tuned engines. The 221795S is designed as a direct replacement for the stock piston, making installation straightforward if you're already familiar with engine assembly.

It's important to note that this piston is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures when working on your engine.
