What is the advantage of a forged piston over a cast piston?

Forged pistons are made by heating and hammering aluminum, which creates a denser, stronger grain structure. This makes them more resistant to deformation and failure under high stress and temperature compared to cast pistons.

Does this piston come with rings, pins, and clips?

This product listing is for a single piston only. Piston rings, wrist pins, and clips are typically sold separately and should be ordered according to your engine's specifications.

Can this piston be shipped to California?

No, this piston is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

This is a JE Pistons PRO Piston Single, part number 284670S, designed for the Honda CRF450R. If you're looking to rebuild or enhance the engine in your CRF450R, a well-built piston like this is crucial for performance and reliability. It's a key component that works with the cylinder to create combustion, and its design directly impacts how your engine runs.

JE Pistons is known for making strong internal engine components. This PRO piston is forged, meaning it's made from a solid block of aluminum that's heated and hammered into shape. This process creates a much stronger and more durable piston than cast ones, which is important for handling the high pressures and temperatures inside an engine. The specific design of this piston is intended to work with the stock cylinder dimensions of the CRF450R, making it a direct replacement for a worn-out piston or an upgrade for a performance build.

When installing a new piston, it's important to ensure the cylinder bore is properly prepared and that you follow the manufacturer's recommended clearances. This piston is sold individually, so make sure you order the correct number for your engine.
