Transmission - Wide Ratio

Made in United Kingdom WARNING: This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

The long awaited Wide Ratio Transmission from Nova Racing. Now you can have your trail gearing without giving up your highway gearing.

Both sets are lower than stock in 1st and 2nd gear and taller than stock on 3rd thru 5th gears. Not only will Nova give you better gear ratios but the high quality components will shift smoother and engage more solidly. The tables below show each gear ratio and the original OEM ratios for comparison.

To help put the ratio changes into perspective switching from the OEM 15T to a 14T sprocket lowers the gearing by 7.1% in all gears. Switching from a 15T to a 16T raises the gearing by 6.6% in all gears.
