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
Nice throttle tube. Painful install if using Oxford heated grips.
The standard throttle tube on my VStrom had several ribs running the length of it, which I would have needed to shave off in order to install the Oxford Heated Grips I had also purchased, so I decided to just buy this and do a swap instead. I also wanted a metal throttle tube under my new heated grips, since on my previous bike the throttle tube side never seemed as warm as the other, so thought having both grips installed over metal might help).
Install of the this throttle tube was simple. Loosen the cable adjustment barrels, take out a couple screws from the handlebar clam shell unit (containing the kill switch, etc.), pop the cables out, slide the old throttle tube off. Install this tube in reverse order - fairly easy.
I was finally ready to install my Oxford grips, only to find during my test fit, that the raised knurls on this throttle tube prevented the new grip from sliding on. 3 hours of hand filing later (didn't want to file through this new tube, as the walls are quite thin) I was finally able to get the grip on.
Once installed, the tube performed beautifully - very smooth. Seems to help with the low-end 'jumpiness' of the VStrom, when riding in low gears and/or at low RPMs (I completed the install over the winter, so unfortunately didn't have the 'before' fresh in my mind to compare to the 'after').
Overall I would recommend the unit. A bit on the pricey side, and final install was painful, but that was mostly due to my grip choice. That said, if I find myself installing heated grips on another bike, this will be step one.

William K asked:Since my bike is so new I don't expect it to be listed on many fitment guides. Is there another way I can figure out if this will work? I have a 2014 Honda CBR650FA. Thanks in advance.Jul 15, 2014
Jay A asked:I am interested in a G2 Tamer for my 2008 H-D VRSCDX (Night Rod Special) - will this or another product fit? Or another throttle tube that is 1/4 turn 0 throttle to WOT with a gradual cam for the throttle onset so it is more controllable on the street. I do have a 1" O.D. handlebar and dual cable pulls for the throttle. No mention of handlebar size for this product and though it comes up as something that "fits" re: my Garage I can't tell for sure that it does,Dec 13, 2014
