G2 Throttle Tamer Aprilia Tuono

G2's challenge was to improve control of over-responsive power characteristics of most fuel injected motorcycles. Their solution is the throttle tamer.

The Throttle Tamer incorporates a non-linear ratio between hand throttle rotation and carburetor or throttle body opening.  The “pulley”, or as they 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 Throttle Tamer 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 virtually eliminates the jerky “throttle snatch” especially evident in modern fuel injected street bikes.  The radius increases or “ramps up” after ½ throttle to keep overall rotation requires 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
  • Included cam is removable and can be replaced with alternate cams (sold separately) to fine tune control
  • Fits inside the stock throttle housing to stock cables
  • Works with all known aftermarket cruise controls
  • Slide your grip unto the Throttle Tamer

Note: Image for reference only. Actual G2 Throttle Tamer may vary depending on your bike's make and model.
