JE Pistons Yamaha YZ450F 14 to 1 Piston Single

This listing is for a single JE Pistons forged piston designed for Yamaha YZ450F models. It features a 14 to 1 compression ratio, which is a notable increase over stock, intended to boost performance for riders looking for more power. The piston is constructed from forged aluminum, a strong material that holds up well under the stresses of high-performance engines.

Forged pistons are known for their durability and resistance to deformation, making them a solid choice for demanding applications where stock cast pistons might not be sufficient. This piston is a direct replacement for your original, though it's important to note that due to its higher compression, it may require adjustments to your fuel and ignition tuning to perform optimally and prevent detonation. This part is not CARB approved and cannot be shipped to California.
