Product Details

This is a JE Pistons forged piston designed for the KTM 250SXF. It features a 13.5 to 1 compression ratio, which is an increase over stock, giving your engine more power. JE Pistons are well-known for their durable construction and precision manufacturing, making them a solid choice for rebuilding or upgrading your KTM's engine.

Forged pistons like this one are made from a solid block of aluminum that is heated and hammered into shape. This process creates a stronger, more resilient piston than cast pistons, which are poured into a mold. This improved strength means the piston can handle higher compression ratios and more stress, which is important for performance applications. This specific piston is designed as a single unit, meaning it's sold individually, so you can replace exactly what you need.

Keep in mind that this piston is not CARB approved and cannot be shipped to California. Always refer to your service manual for proper installation procedures and torque specifications when working on your engine.
