The G2 Dirt Tamer Throttle Tube (p/n 30-4K-K) 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. 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 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 eliminate aluminum-to-aluminum contact and provide an ultra-smooth feel.
Fits inside the stock throttle housing to stock cables.
Removable end cap for easy enduro handguard installation.
Grips not included.
