Product Details

This is a single forged piston from JE Pistons, specifically made for the Yamaha SIDWINDER R-TX TURBO. It features an 8.5 to 1 compression ratio, which is a notable change from stock and is designed for boosted applications where you need to manage cylinder pressures. JE Pistons is a well-known name in high-performance engine components, and these pistons are built for demanding use.

Forged pistons like these are stronger and more durable than cast pistons, making them a solid choice when you're rebuilding or modifying an engine for increased power. The 8.5:1 compression ratio is ideal for forced induction setups, allowing you to run more boost without risking detonation. This piston is sold individually, so you can replace exactly what you need or build a custom set for your engine.

Keep in mind that this piston is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's specifications and recommended installation procedures when working on your engine.
