Show original supplier description
The Aftermarket Assassins S2 Clutch Kit is engineered to significantly enhance the performance of your Kawasaki KRX 1000. This kit directly addresses the factory's detuned timing map and lean fuel curve, unlocking substantial horsepower gains. Users can expect quicker throttle response, improved acceleration, and a more efficient power delivery to the rear wheels, making the machine more responsive on trails, in dunes, or during mudding. The kit includes AA Recoil magnetic adjustable clutch weights, featuring a custom profile and a nitrocarburizing coating for superior wear resistance and surface lubricity. These weights are designed with more tip weight mass, leading to harder belt grip and faster acceleration while maintaining smooth low-end engagement suitable for crawling. The magnetic adjustability allows for tuning to various tire sizes, modifications, and future upgrades, with the ability to adjust from 84-100 grams and up to 120 grams for turbo applications using optional slug magnets. The kit also includes a dark green primary spring and a setup guideline. This clutch kit is specifically designed for 2020-2024 Kawasaki KRX 1000 models. It is important to note that 2025 models use a different 3-arm clutch system and require a separate listing. The product enhances performance by optimizing the primary clutch, with the stock secondary clutch generally working well. Peak RPM at 50 MPH should be checked and set to 7000-7200 RPM for optimal performance.
