JE Pistons Honda CBR 250R Piston Single

This JE Pistons 308447S is a 0.040 inch undersize forged piston, specifically made for the Honda CBR 250R. Forged pistons are a strong choice when you need more durability than a cast piston can offer, especially if you're rebuilding or modifying your engine for increased performance. JE Pistons is a well-known name in performance engine components, and this piston reflects that reputation with its solid construction.

The forged aluminum construction means this piston can handle higher compression ratios and temperatures compared to cast pistons. This is important because it helps prevent premature wear and potential failure under demanding conditions. The 0.040 inch undersize specification is critical for engine rebuilding; it means this piston is designed to fit into a cylinder bore that has been machined to be 0.040 inches larger than its original factory size. This is a common practice when reconditioning an engine to ensure a proper seal and optimal performance.

When you're working on your CBR 250R's engine, using a piston from a reputable manufacturer like JE Pistons ensures you're getting a part that's built to perform. Remember that this piston cannot be shipped to California due to CARB regulations.
