Throttle Cam System -
The G2 Throttle Cam System can make your bike easier to
ride in rough, technical conditions. By utilizing
different cams on the throttle tube for different track
or trail conditions, you will have increased control of
the power delivery, resulting in better control of your
motorcycle and less wasted energy due to unwanted wheel
spin or abrupt power delivery.
The G2 Throttle Cam
System kit comes with Cams 100, 200, and 400. The 200
and 400 cams allow a more precise control of throttle
opening during the 1/3 of throttle opening, but retain
the same overall rotation to full throttle.
Cams 050 and 300 are
available separately. Cam 050 also comes in the

CAM 200 - use for
intermediate conditions or moderately technical trails. 8-10%

The Throttle Cam System.
The Throttle Cam System incorporates 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
The Throttle Cam System has cam options with reduced radius for
the first ˝ 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 ˝ throttle to keep
overall rotation required to reach full throttle at or near

|We recommend that you
ride and evaluate the TCS before competition to try the three
cams and feel how each effects your control. For best results,
try on a track as similar as possible to your normal racing
Your Throttle Cam System includes three cams (CAM 100/200/400).
The CAM 100 is similar to your stock cam. The CAM200 has a
“cammed” shape with a slightly smaller radius in the first 1/4
turn of the throttle. The CAM 400 has a more pronounced “cam”
shape with an even smaller radius for the first 1/4 turn of the
For best results, start with the CAM 400. This will show the
maximum amount of control with the system. After a few laps,
change to the CAM 100 (stock). Going back to the stock feel will
provide a point of reference and demonstrate the advantage of
this system. Now try the CAM 200. For the remainder of your test
session, switch cams several times to feel which cam works best
in different conditions. This is crucial to teach yourself which
cam to Select for different conditions.
1. Attach cam to tube with grip securely installed. It is
recommended that grip glue is used and safety wire installed.
Allow time for glue to properly set per manufacturers
CAM 100 - installation is same as stock.
2. With engine turned off, slide tube/cam onto handlebar and
attach throttle housing. Tighten bolts on housing to
3. Insert throttle cable into throttle housing and attach
barrel of inner throttle cable to cable "keyhole" on CAM 100 with
the small top throttle housing cover removed. Next, install
cable pulley and top throttle housing cover per manufacturers
4. Adjust throttle cable free play per manufacturers
recommendation before operation.
