JE Pistons 3.425 Honda XR400R Piston Single

JE Pistons is well-known for making strong internal engine components, and this forged piston for the Honda XR400R is a prime example. If you're rebuilding the top end of your XR400R, this piston is built to handle the demands of the engine. It's a single piston, meaning it's sold individually, so you can replace exactly what you need.

This piston is forged from aluminum, a process that creates a very strong and durable part. Forged pistons are generally more resistant to detonation and can withstand higher compression ratios and more aggressive tuning compared to cast pistons. The 3.425-inch bore size is specific to the Honda XR400R, ensuring it fits correctly within the cylinder. This part is not CARB approved and cannot be shipped to California.
