The G2 Dirt Tamer Throttle Tube for Yamaha incorporates 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 most models the Throttle Tamer includes a 400 style cam profile, but some will have alternative cam profiles. The cam proven to be the best all-round solution for each model is used.
The G2 Dirt Tamer Throttle Tube has a cam with a reduced radius initially, which requires a slightly farther rotation to achieve the same carburetor or throttle body opening position as a stock throttle. This slightly longer pull makes a HUGE difference in control as the power is rolled on and the rider searches for traction. The radius increases or ramps up after ½ throttle to keep overall rotation requires to reach full throttle at or near stock rotation.
G2 cams are interchangeable! You are never stuck with a ratio that is not correct for your skill or track condition! You can always go back to the stock ratio, quicker, or for most models several different progressive control ratios! Cams may be ordered separately, or consider the G2 Throttle Cam System that includes a tube and three cams – 100 (stock), 200 (10% smaller & progressive) and 400 (20% smaller & progressive).
