This is a JE Pistons forged piston designed for Yamaha YZ 250F motorcycles.

JE Pistons are well-known for their forged pistons, which are stronger and more durable than cast pistons. This makes them a solid option for high-performance applications where increased stress is placed on engine components. The 14:1 compression ratio is achieved through the piston's dome design, which helps to increase the power output of the engine when paired with appropriate tuning. This piston fits specific Yamaha YZ 250F models, ensuring a direct fit for those looking to rebuild or upgrade their engine.

When installing this piston, it's important to ensure your engine is properly tuned to take advantage of the higher compression. This often involves adjusting fuel and ignition timing. Keep in mind that this piston is not CARB approved and cannot be shipped to California.
