Product Details

JE Pistons is well-known for making strong, reliable engine components, and this forged piston for the Honda CBR 500R is a great example of that. If you're rebuilding the top end of your CBR 500R's engine, this piston is built to handle the demands of performance riding. It features a 67mm bore and a 12.0 to 1 compression ratio, which is a notable bump over stock, giving you improved power output.

This piston is forged from high-strength aluminum, a common practice for performance pistons because it offers a good balance of strength and weight. Forging creates a denser, more uniform grain structure compared to casting, making it more resistant to deformation under high pressure and heat. This means it can handle the increased stress that comes with a higher compression ratio. It's designed as a single piston, so you'll need to order the correct quantity for your engine.

Keep in mind 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.
