Baker Drivetrain

Baker Sportster 6-speed conversion

The new
Baker Drivetrain XL6 is a six-speed overdrive ‘cartridge style’ gearset that converts any existing 5-speed 1991-2003 Sportster or Buell to a Baker six-speed, with 2nd through 5th gear ratios remaining effectively the same as stock, and a 6th gear that is a true overdrive for a 511 rpm drop at 75 mph.

Featuring a 6061-T6 billet aluminum trap door, the complete gearset includes shafts and gears, less the 5th (main drive) gear pair - the 5th gear pair from the existing 5-speed is re-used.
The gearset is pre-assembled to the trap door including bearings, thrust washers and retaining rings; the shift drum and detent plate have “optimized geometry” with “no flimsy retaining clip to hold the detent plate to the drum – ours is bolted on with a machine screw.
“We use a low effort detent spring, three billet steel shift forks with roller pins and cotter pins and a steel template for accurate case modification.”
Available for stock Sportster applications (1991 – 2003) and for S&S cases with their special bearing door configuration.
