The G2 Throttle Cam System allows you to fine tune hand movement/rotation to what happens at the carburetor/throttle body. How can one throttle ratio be expected to work for every rider! Beginner? Expert? YZ125? KTM450? Sand track? Tight woods? The Throttle Cam System allows the rider to adjust throttle cam despite these variables. 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 as we call it, “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. Want something quicker, check out our 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.
Machined from 6061 aluminum in the USA.
Self-lubricating Delrin bushings at each end of tube provide an ultra-smooth feel that won't rust like bearing throttles.
