G2 Throttle Cam System for Yamaha
The G2 Throttle Cam System for Yamaha allows you to fine tune hand movement/rotation to what happens at the carburetor/throttle body. Why would you want to change this ratio? Imagine the pointer on your computer had only one speed with no adjustment. Chances are it would be annoyingly slow or so fast you would over shoot everything you want to click! At G2 Ergonomics, we wondered why one throttle ratio is expected to work for every rider! Whether you’re a beginner, an expert, riding a 250 2 stroke or a 450, most throttle ratios are basically the same! It’s really pretty crazy when you think about it! In fact, eight time National Enduro Champ Mike Lafferty constantly changed his G2 cams depending on terrain and average speeds!
The system includes a stock ratio cam and two progressive cams that incorporate 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. For those who want their Yamaha more responsive, check out our Quick Turn Throttle!
The Throttle Cam System for Yamaha has cam options with reduced radius for the first ½ of throttle rotation, which requires a slightly farther turn to achieve the same carburetor or throttle body opening position as a stock throttle. This slightly longer pull makes a HUGE difference in rider control as the power is rolled on. The system comes with a “100CAM” – same as stock, “200CAM” – starts out 10% smaller than stock and “400CAM” – starts out 20% smaller than stock. The radius of the 200CAM and 400CAM increases or “ramps up” to stock size at ½ throttle to keep overall rotation required to reach full throttle at or near stock rotation. The 200CAM is the cam of choice by the AmPro Yamaha GNCC Team!

I’m no stranger to big bores racing CR500’s in moto for years and qualifying for loretta’s in 2 classes. my 21 yz450fx had such a snap off bottom clutch work was crucial in slick Indiana trails. team yamaha sent me an awesome map that really helped but not completely. they suggested the G2 throttle that they use and the bike is spectacular. thanks to Randy and Lucas and G2!!!
Rikard Marchall –
An amazing product. Finally, I can control even slow cornering.
PAUL DUNNE –
Made riding much more controllable
Alexander Sari –
Works as advertised. Going to be on every bike I ride from here on forward.
Scott –
Throttle is very smooth and a lot easier to control the bike in slower situations
Wade Gunoff –
Cant give full 5 cause havent tested yet but like looks
Jon Angus –
Definitely a quality throttle. Smooth action, havent had a chance to play with all the cams yet, but i doubt ill be disappointed in the performance.
Charles J. –
Easy installation, smooth operation.
andrew c. –
Gets rid of that unpredictable burp of the YZ250FX and smooths out power when you need to be more deliberate.
Anonymous (Verified Purchase) –
Great quality cured my throttle control problems when tired
Mike (Verified Purchase) –
What a difference between stock and G2! Widen your throttle range for dirt trails, I’m spending more time in 3rd & riding faster! Went from stock to 20%, but still have options to tighten up.
Jason Williams (Verified Purchase) –
21 WR450 uncorked, tuned with fmf. I love the power, but the initial torque can be exhausting to handle. The throttle tamer makes it much more enjoyable to ride. As my skills progress I can tune it progressively more aggressive as I wish.
Kevin S. (Verified Purchase) –
The single best purchase for making my YZ450FX easier to ride in tight woods.. would for sure recommend for this purpose..
Marlen (Verified Purchase) –
Nice quality machine parts…can’t wait to get installed and test for next season riding!
richard s. (Verified Purchase) –
I really like having the various throttle cams. I’m using the 20% now and it’s a huge improvement on my off road-low speed control, definatly worth it. But, the stock cam/cable housing is a bit too small so I leave the the bottom open a bit and tighten down on the top. I don’t know of a remedy or replacment for that. xt250-09
