Naraku Racing Crankshaft for HPC-CPI/Keeway/China 2T E2

The Naraku Racing HPC crankshaft represents an ideal choice for those looking to enhance the performance of their motorcycle. Specifically designed for CPI models, Keeway, and other 2-stroke Chinese vehicles, this HPC crankshaft is manufactured following the strict OEM guidelines of Japanese manufacturers, ensuring optimal compatibility and reliability.

Its full cheek structure allows for an increase in pre-compression in the crankcase, significantly improving cylinder filling and shifting the power band towards the upper range. This means that even on 50cc cylinders, the crankshaft delivers high performance without compromising stability. The plastic counterweights used in this model help keep the overall weight down, allowing for agile and responsive handling of the motorcycle.

With a piston pin diameter of 12 mm and an original stroke, the Naraku crankshaft is designed to integrate perfectly with your vehicle's existing system. The connecting rod length is also original, ensuring simple installation without the need for modifications. Whether you are a racing enthusiast or simply want to improve your motorcycle's performance, the Naraku Racing HPC crankshaft is the perfect choice for an exciting and high-performing riding experience.
