As a general rule, the lower the number on your G2 Cam – the quicker your throttle opens to full power. The higher the cam number – the more control you’ll feel. The stock cam size is 100 for most models. G2 cams are interchangeable, so you can always make a ratio change! These cams fit all G2 and Moose Racing aluminum throttle tubes.
Cam Size Information (may vary for certain models):
- 00k CAM – Approximately 30% larger than stock*
- 025 CAM – Approximately 20% larger than stock*
- 050 CAM – Approximately 10% larger than stock
- 100 CAM – Approximately same size as stock.
- 200 CAM – Approximately 10% smaller for first 1/2 of throttle rotation, then ramps to stock size.
- 300 CAM – Approximately 15% smaller for first 1/2 of throttle rotation, then ramps to stock size.
- 400 CAM – Approximately 20% smaller for first 1/2 of throttle rotation, then ramps to stock size.*
Not all G2 Cams sizes are available for all models.
*00K cam and some 025 cams require small modification of inner throttle housing with file or dremmel tool. Instructions provided with cam. DO NOT ASSEMBLE WITHOUT PROPER MODIFICATION!

I bought the K300 cam for the KTM 990. I felt that the K400 had a bit too much of an abrupt transition from its low-throttle ramp to mid/high throttle ramp. The K300 seems just right and has made the bike a lot less jerky. Now the engine doesn’t lurch every time I go over a bump. Throttling on in corners is much smoother and not so unpredictable any more. The only reason I don’t give 5 stars is that I wish the kit G2 sells with the various cams came with the K300 to begin with. It came with every cam but so it was an expensive trial-and-error.
This is my second time using this product and it is easy to install, well made, and cured the lurching that was present in both my KTM 990 and KTM 690. I used the #200 in the 990 with a set of C/F slip ons, and it made a world of difference, especially off road. The 690 had come with the system installed, but had a #400. I switched it out easily, and put another #200 in and it works great for me…5 stars all around !!!!
I have multiple G2 products. First, this is a must for any fuel injected twin. We all tend to be less talented than we think and this product will make up for a huge gap in throttle manipulation. I have been riding and racing twins for years and this product on my Monster 1100 was quite humbling. I was able to learn much more in a turn and through turbulence laid over with the throttle tamer cam system. I am slowly progressing back through the cams to stock ratio as I continue to develop and build better throttle control. This product is awesome.
Second, I also have this system on my KTM 300 XC-W. I am new to dirt and more of a YouTube video waiting to happen. Once again, G2 helped me save my own life when things got and get squirrley in the woods. I am not a MX racer and do not ever leave the ground intentionally while on my dirt bike. I can definately see, even with a dual ignition pattern switch, how this product pays huge dividends on the MX/SX track.
The 200 didn’t do much for me and I had to do some shaving on my ktm to fit it. I don’t think a 300 would fit but I might try it.

Great- I ordered two of them and have no way to tell them apart. How about better labeling?
