Product Details

If you're rebuilding the top end of your Honda CRF 450 and looking for a performance boost, this JE Pistons forged piston is a solid option. It's designed to replace the stock piston and offers a higher compression ratio for increased power output. This piston is built for riders who want more out of their engine.

This piston features a 12.5 to 1 compression ratio, which is a notable increase over stock. Higher compression generally means more power, especially when paired with proper tuning. JE Pistons are well-known for their forged construction, which makes them strong and durable enough to handle the increased pressures and heat associated with higher compression. This particular piston is sold individually, so you'll need to order the correct quantity for your engine.

When installing this piston, remember that higher compression often requires careful attention to fuel octane and engine tuning to prevent detonation. Always refer to the manufacturer's installation instructions for specific details and recommendations.
