JE Pistons Honda CRF250 PRO Piston Kit

As the leader in forged racing pistons, JE Pistons has applied over 75 years of experience to its range of Pro Series pistons. Pro Series® Piston kits feature purpose-built forging designs that reduce overall piston weight without sacrificing strength or durability. Internal and external strut braces significantly reduce stress on critical areas while ultra-flat ring grooves improve ring seal for better, sustained performance.

Note for Pistons, Rings, Rotors, Rods and engine internals

Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately. In some cases, titles may indicate plural, or 'set' - eg the term “ring set” often refers to the rings for a single piston only. If you’re unsure about what’s included with this product, please contact our team for clarification.
