Baker Direct Drive 7-Speed Gear Set - '17-'25 M8 Models

The Baker Direct Drive 7-Speed Gear Set replaces the factory Cruise Drive 6-speed in '17-'25 Milwaukee-Eight models with a seven speed that slides in without case work.

A seventh gear is not about going faster. It is about having somewhere useful to put the torque an M8 produces, and about closing the gaps between the gears you already use. Baker shortened first, tightened everything above it, and added an overdrive on top, so acceleration stays continuous from first through fourth instead of arriving in steps.

How the DD7 Gear Set Is Built

The stock mainshaft carries first through fourth gear. The DD7 mainshaft carries only the small first gear, which makes it substantially lighter and is the reason shift clunk drops noticeably. A linear roller ball detent in the supplied billet top cover handles engagement, and shift feel is where that shows up. Door bearings are 28 percent wider than stock. Everything is made in the USA.

It arrives ready to slide into the bike: no case modification, no shimming of the gear set, no adjustment. The stock shifter pawl is reused.

Before You Order the DD7

This is the Milwaukee-Eight version of the Direct Drive 7-Speed and it replaces the factory Cruise Drive 6-speed. Baker builds the DD7 for more than one Harley-Davidson motor family, so if your bike is a 2016 or earlier Twin Cam you need a different gear set. Contact us with your year and model if you want confirmation before you buy.
