What is the difference between a forged and a cast piston?

Forged pistons are made by heating and hammering aluminum into shape, which aligns the grain structure and makes them stronger and more resistant to heat and pressure. Cast pistons are made by pouring molten aluminum into a mold, which is a simpler process but results in a less durable piston.

Does this piston come with rings and wrist pin?

This JE Pistons part number 247953S is for a single piston only. Rings and wrist pin are typically sold separately, so please check the product details or order them as needed for your rebuild.

Can this piston be shipped to California?

Product Details

This is a single forged piston from JE Pistons, specifically made for the Yamaha YFZ450 models from 2006 through 2008. If you're rebuilding or upgrading the engine in your YFZ450, a quality piston is key to getting reliable performance back. JE Pistons is a well-known name in performance engine components, and this piston is built to handle the demands of the YFZ450's engine.

Forged pistons are generally stronger and more durable than cast pistons, making them a popular choice for performance applications where higher compression or more aggressive riding is expected. This piston is designed as a direct replacement for the stock unit, meaning it should fit right into your existing engine assembly. JE Pistons uses advanced manufacturing techniques to ensure their pistons meet strict tolerances, which helps with proper sealing and efficient combustion.

When rebuilding an engine, it's important to ensure all components are compatible and installed correctly. This piston is sold individually, so make sure to order the correct quantity for your engine. Please note that this part is not CARB approved and cannot be shipped to California.
