G2 Street Throttle Tamer Tube for Aprilia


SKU: N/A Category:


The G2 Street Throttle Tamer Tube for Aprilia 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 and “throttle snatch” is drastically reduced.

The G2 Street Throttle Tamer 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 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.  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.

G2 has offered the Street Throttle Tamer Tube for 12 years with thousands of satisfied customers.  We guarantee you will find this the best investment in control you have ever made, or you can return the throttle for a full refund!  At G2, we stand behind our products and pride ourselves on the best customer service.  If you have ANY questions about our throttle, please call or email (see contacts page).  We guarantee a human will answer the phone or respond to your voicemail within one business day!

Our applications for Aprilia are a bit out of date due to no access to microfiche nor a local dealer.  Most of what we know has been determined with the help of our customers.  If you do not see your particular year/model listed, please call or email (see contacts page).  So far, all newer Aprilia models use a Throttle Tamer Tube that we designed for an Italian-made Domino throttle controller.   Let us know what model you have and we’ll do our best to figure out which application will work!
