Product Description

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 your a beginner, an expert, riding a 250 2 stroke or a 450, most throttle ratios are basically 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 something quicker, check out our Quick Turn Throttle!

The Throttle Cam System 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.

    I have a CM GP450 which has low speed shunt issues. The throttle tamer has made this problem more manageable and the bike is easier to use on technical stuff. I used one previously on my WR250R and it made the bike much more manageable in the Colorado Rockies on the high passes especially sand and rocks. Well worth the money, easy to fit and excellent quality. Attension to the cable adjustment fine tunes it.

    This is definitely a MUST for all expert and pro riders who want that instant boost of power at the control of your wrist. Made a huge difference in my aggressiveness when it comes to passing people!

    Installed on 2010 Yz 450 and it made the bike much more predictable with the 400 cam installed. The low end punch was reduced and throttle overall control increased. I would buy again/recommend to a friend.

    Gets rid of that unpredictable burp of the YZ250FX and smooths out power when you need to be more deliberate.

    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!!!
