FITS THE FOLLOWING MODELS:
G2 Ergonomics manufacturers the nicest billet aluminum throttle tubes on the market. Professional racers use aluminum throttle tubes because they are unbreakable! When a plastic throttle tube breaks it causes your throttle to loose its ability to modulate the throttle effectively. Typically what happens is the tube breaks lengthwise or around its diameter causing the grip to them put pressure on the handlebar resulting in a stuck throttle. G2's billet throttles fixes this problem. Their throttle tubes take things one step further by incorporating Delrin sleeves located inside the tube which results in smoother throttle delivery.
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. For those who want something quicker, check out our Quick Turn Throttle! All G2 cams for KTM are machined in the USA from, 6061 aluminum or self-lubricating white or black Delrin.
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.
