The Wiseco K1747 is a forged piston kit with a 10.5:1 compression ratio, built from high-silicon aluminum for riders who want a more responsive and durable V-twin engine. Wiseco pistons are made to a precision diamond-turned finish, and the kit is designed to work with all common cylinder bore types.
Forged high-silicon, low-expansion aluminum gives these pistons greater strength than cast pistons while keeping the weight down. The reduced weight improves engine response, and the alloy offers improved heat dissipation for longer engine life. The 10.5:1 compression ratio is intended to deliver a noticeable increase in throttle response and overall engine output.
These Wiseco pistons suit riders who expect more from their engine and are a practical choice for performance builds. Because the increased compression changes how the engine runs, the product information recommends consulting a professional tuner after installation to optimize performance and longevity.
For off-road / closed-course race use only.
