How many pistons do I need for my Honda CBR 250R?

The Honda CBR 250R typically has a single-cylinder engine. This product is sold as a single piston, so you would need one unit for a standard rebuild. Always confirm your specific engine configuration.

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

Forged pistons are made by heating and hammering aluminum, which aligns the grain structure of the metal. This results in a stronger, more durable piston that can better withstand higher compression ratios and increased cylinder pressures compared to cast pistons.

Does this piston come with rings or a pin?

This product listing is for the single piston only. Piston rings and wrist pins are typically sold separately. Please check the product details or contact us to confirm what is included with your order.

Product Details

This is a single forged piston from JE Pistons, designed specifically for the Honda CBR 250R. If you're rebuilding or upgrading the engine in your CBR 250R, a quality piston is crucial for performance and reliability. JE Pistons are well-known in the performance engine world for their durable construction and precise manufacturing.

This particular 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 resilient piston than cast aluminum, which is important for handling the increased stresses in a performance engine. The 308450S is a single piston, so you'll need to purchase the correct quantity for your engine. It's designed to fit right into the stock cylinder bore, making installation straightforward for someone familiar with engine work.

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 details.
