Product Description

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 tried flywheel weights, pipes, was even considering an auto clutch to try to even out the power on my YZ250. These work. The #400 was nice but I like the #500. It puts a real sweet spot in the mid range, works great on technical hill climbs. No flywheel weight, using a Gnarly pipe.

    I use the 10% slower throttle cam on my WR250R, the 20% slower that came with the tube was a bit too slow and I was tired of twisting the throttle so much. I’m impressed with G2 products.

    Haven’t used it yet as the 400 cam has been amazing but good to have the versatility
