Product Code: G2-40-215
The G2 Throttle Cam System allows you to fine tune hand movement/rotation to what happens at the carburetor/throttle body. Why would you want to change this ratio? Imagine the cursor on your computer had only one speed with no adjustment. Chances are it would be annoyingly slow or so fast you would shoot past everything you wanted to click!
The system includes a "stock" ratio cam and two progressive cams that incorporate a non-linear ratio between hand throttle rotation and carburetor or throttle body opening. The "pulley" or "cam" pulls the throttle cable as the rider rotates the grip/tube. By altering the conventional, circular shaped cam, a vast improvement in control is achieved. For those who want something quicker, check out this Quick Turn Throttle!
The Throttle Cam System has cam options with reduced radius for the first ½ of throttle rotation, which requires a slightly farther turn to achieve the same carburetor or throttle body opening position as a stock throttle. This slightly longer pull makes a HUGE difference in rider control as the power is rolled on. The system comes with a “100CAM” – same as stock, “200CAM” – starts out 10% smaller than stock and “400CAM” – starts out 20% smaller than stock. The radius of the 200CAM and 400CAM increases or “ramps up” to stock size at ½ throttle to keep overall rotation required to reach full throttle at or near stock rotation.
