So I know there are many of you out there that are very interested in the little bit of info I recently got my paws on.

1st Gear -37.5%
2nd Gear - -25%
3rd Gear - Direct Drive
Gear step gear 1 to gear 2: 20%
Gear step gear two to gear 3: 33%
Shifters are still up in the air but we have had many requests for a bar end style shifter. Also we are still planning on the possibility of doing some anodized colors with laser etching instead of screen printed graphics. Please comment on what you would like to see in the way of shifters or color choices.
