DR650 '96 - '26

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.

This 3rd gear set is made for us by Nova Racing Transmissions in England to replace the fragile stock third gear set. These folks build complete transmissions for World Superbike teams among others, so we believe them to be highly qualified to build this set of replacement gears.

These gears are made from a high quality special alloy steel and then heat treated and superfinished. The mainshaft drive gear and the countershaft driven gear are sold only as a set.
