Jims 6-speed overdrive transmission super kits:
Reduce vibration that creates wear, and enjoy a relaxing cruise with Jims overdrive 6-speed transmission super kits. Jims’ overdrive 6th gear (0.86:1 ratio) lowers engine RPM by almost 475 at 75 mph. In addition, 1st gear is a 2.94:1 close ratio that widens your bikes speed range in 1st gear and lessens the rpm drop when shifting into second. You can enjoy having a gear for every situation, from putting in traffic to open road cruising. Combined with the convenience of well-spaced gearing is the renowned strength and reliability of Jims race-proven, American-made gears and shafts.
All gears are standard width for performance and strength, with first gear being close ratio 2.94, and the last four being the same ratio as a stock 5-speed. 6th gear goes to 0.86:1 overdrive. These kits are ready to slip into your transmission case without removing it from your motorcycle. Detailed instructions and a Jims gasket set are included.
