G2 Throttle Tamer Triumph

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

hesitant to buy, but glad I did. happier with the throttle feel on the tiger, now It's a little easier to be smooth on the throttle now. Shifts are a little more consistent for me, especially when short shifting. Install was a little disappointing. the bars on the tiger are a little too short to fit the delrin bushing on the end of the tamer tube. I machined a custom piece to make it fit tighter. without it the tube was pretty sloppy. also, the stock grip fits loose; requiring it to be safety wired. August 10, 2016
A significant improvement in throttle response This unit goes a long way toward moderating the abrupt on/off throttle response of the Street Triple. The G2 throttle seems to be well-made and it's a breeze to install. It takes more time to remove the stock grip than it does to install the G2 throttle tamer. The stock Triumph grip was a loose fit on the G2 tube - easily fixed with some grip glue. Great bang for the buck. March 11, 2016
This product works ok but...... The G2 throttle tamer did possibly tame the the abruptness of the throttle on my 2014 street triple R a minimal amount, but the fit was not very fitting on my model. It is made of steel and has nice delron bushings on the inside of the tube for smoothness, but the placement of the bushing is wrong for my model and leaves it sloppy out on the end of the handle bar. For the price it should be better quality and come with glue or tape to attach the grip. All though I do like the idea of this product, I was not impressd April 6, 2015
Easy install, worked on my triumph Tamed my triumph tiger 800 throttle, allowing me to ease on the throttle in off road applications, giving me a more controlled ride. March 2, 2015
Works exactly as advertised My 2012 Tiger 800XC is a great bike but the throttle is touchy, especially off road. This product, which was super easy to install, took out the "twichiness" but still left the throttle very responsive. Bike should come this way out of the box. I just did about 100 miles of dirt roads last week and this product made it much more enjoyable. March 25, 2014
Smooths out the throttle as advertised The Tiger 1050, running a stock can/tune, is notoriously snatchy at low-speed, partial throttle - hunting and surging is a common malady and there are a lot of ways to treat it. I went with this option because it seemed both the cheapest and simplest method without messing with the ECU or anything else on the bike. Since I was replacing grips anyway, I decided to try it out. It definitely smooths out the throttle response, though I'm slightly baffled as to how it works. I'm going to have to tighten up a bit of slack in my throttle cable, but it has definitely civilized the manners of the bike in partial-throttle, stop-n-go traffic without requiring clutch feathering. Nice product, simple design. Wish it was a BIT cheaper, but I've learned to just stop looking at the credit card statements. November 18, 2013
