Baker Drivetrain 6 Speed Overdrive Gear Set For Harley Big Twin Evo

The Baker OD6 6 Speed Gear Set will drop into your factory transmission housing providing you with a crucial 6th gear that reduces engine speed by 500 RPMs at 80MPH. Reduce vibrations, save fuel and take comfort knowing that your motor is happy to run at highway speeds. The OD6 is a perfect choice for aggressive riders on bikes with built motors. Because the OD6 utilizes a true overdriven 6th gear, any sprocket can be used allowing a wide variety of gearing options.

The OD6 provides more than just economical highway cruising. All gearsets are made out of 8620 steel that is cut before heat treating then precision ground creating a gearset rated to 165ft/lbs of continuous torque! Baker utilizes a roller detent shift drum with reduced inertia and gear dogteeth with 4 degree undercut ramps to provide solid clutch engagement, necessary for modified powerplants.

Fitment Notes & Exceptions

OD6 Notes:

Bearing door is 1/2" wider than stock which may require modification to the exhaust bracket
Speedo recalibration unit is required for electric speed sensor applications
Baker recommends a fully synthetic GL-5 rated gear weight oil of 75W-140

OD6 (Overdrive) vs DD6 (Direct Drive)

OD6 is meant for performance and race applications up to 165ft/lbs due in part to a more aggressive 4 degree undercut on the clutch dog teeth
DD6 is meant for touring bikes up to 120ft/lbs and offers smoother shifting due to a shallower 1 degree undercut on the clutch dog teeth

Both Gear Sets reduce engine speed by 500 RPM at 80MPH

OD6 has an overdrive (.86:1) 6th gear that can be used with any sprocket for increased gearing options and a more usable (higher) 1st gear
DD6 achieves an overdrive effect on the highway by overdriving the primary with a 28 tooth motor sprocket

Gear Ratios:

1st Gear 2.94
2nd Gear 2.21
3rd Gear 1.60
4th Gear 1.23
5th Gear 1.00
6th Gear .86
