For the 2016-2017 models, Cat did a nice job of upgrading to the Team clutches. However, BMP was still able to make drastic improvements to get your sled running harder than ever before. BMP Stage 2 clutch kits consist of magnetic adjustable primary weights, primary spring, secondary spring, and a custom cut helix. With BMP expert clutch tuning knowledge, and the right components at hand huge gains in  acceleration and backshift are seen with this kit. For mountain riders, you ll see BMP clutching hold RPM much better and track speed will increase because of this.
The primary clutch utilizes the BMP Goldstar magnetic adjustable weights. These weights hit hard on the bottom end, yet are very smooth for cruising, and provide quick throttle response. The weights are adjustable with a unique magnet design allowing adjustment per arm. BMP provides specifications of how to set up the clutch arm weight with each kit. The adjustable weights allow you to precisely fine tune your sled, or adjust for modifications and different altitudes. For example if you added a performance pipe, big bore, or turbo, you can simply add more weight to the Goldstar clutch arms. The 4 positions per side allow you to put more weight towards the heal or tip if you want a change your shift pattern for a harder hit out of the gate, or more top end pull. Lastly, the kit includes the primary clutch spring to increase the engagement slightly, and help for quicker back shifting.
