Looking to improve throttle control when riding off-road, or reduce that snatchy on/off throttle on modern fuel injected bikes? Look no further than G2 Ergo's Tamer Throttle Tube for the Yamaha WR250R and WR250X!

G2 Dirt Tamer Throttle Tubes incorporate a non-linear ratio between hand throttle rotation and 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 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. This also helps eliminate or reduce that snatchy on/off throttle you find on some fuel injected bikes. After 1/2 throttle, the radius increases or “ramps up” to keep overall rotation required 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!
