G2 Throttle Tamer Yamaha

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

Allows easier precise throttle control in lower gears. It is as easy to install as any throttle and made better than the stock unit. Once installed it rotates very smoothly, probably better than stock. It really makes precise throttle control noticeable easier in 1st gear on a powerful bike. Definitely a good mod for bikes that get used every day, in the rain, etc. May 25, 2016
Best Upgrade Ever As a new rider I hated the jerky experience of the stock throttle tube. 80$ seems like allot, but it really makes riding so much better. The low end throttle control is like night and day. Don't worry, you can still do 0-100 in 3 seconds if you want to, just crank her back and you'll be flying in no time. August 31, 2015
Don't expect a whole lot I didn't know what to expect when I ordered it. When I installed it and first tried the bike out, I didn't feel any difference. During the next week of daily commutes to work and stores, I did notice a very slight difference from shifting from first to second. I feel that the price is a bit steep for what you get. I think that if the price was $30-40, it would be a good addition to a bike. June 20, 2015
Tames the snatch ;) If your bike has that snatchy throttle, like my 2005 FZ6, this is your solution. The shape of the "cam" smooths out the initial delivery but does not at all diminish the amount of throttle you can give with a full twist. It's well-made, with good edges that look cleaned up. No burrs or overly sharp aluminum knives waiting to cut you or your grip. It installed in minutes. I could stand it to be slightly less expensive for what it actually is (just a dollar or two of aluminum and a few cents of plastic), but then again, I'd probably pay twice as much to take the snatchy throttle! So maybe the price is fine, based on how much design had to go into this thing to get it right. Highly recommend for my bike. If they make one for yours, you will love it. May 19, 2015
