This is the ORIGINAL 6-speed design that revolutionized the American V-Twin industry. Yet, it’s still the best overdrive 6-speed built to this day…hands down. Baker's OD6 is built to comfortably handle the power from today's big-inch motors. This transmission is rated for motors putting out up to 165ft/lbs of continuous use. It is available as a builder’s kit for your stock case application, which requires little to no modification. The BAKER OD6 is available with many optional gear ratios to match your engine torque and riding style. See Additional Information for fitment.
- Includes polished trap door, all gears, mainshaft, countershaft, shifter drum, detent components, bearings, snap rings, gaskets and hardware
- Significantly smoother shifting than stock due to a roller detent shift drum with reduced inertia and gear dogteeth with lead-in ramping
-
The OD6 door bearings are larger providing 25% more dynamic load capacity than stock bearings used through 1998, also uses a 1/8″ bearing retainer plate instead of stock style snap rings.
- All OD6 gearsets are made out of 8620 steel, gears are cut before heat treat then precision ground with diamond coated tooling after heat treat (58-62 Rockwell ‘C’). This extra steps ensures not only a quieter gear pair, but enables much tighter backlash control. This tighter control on the gears yield a silent operation.
- Baker's investment cast shift forks are made out of 4140 then dipped in a hard chrome plate bath for wear resistance, also designed with oil reliefs to ensure proper lubrication and wear resistance on fork blades and shift dogs.
- Gear ratio of 2.93 (Close Ratio) or 3.24 (Stock) 1st gear and .86 6th gear available
- Fits into stock and most aftermarket 5-speed transmission cases
- Made in the U.S.A.
