G2 Dirt Bike Cams for Yamaha

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.
