GEAR ST DD7 M8 POL

Direct replacement of the Cruise Drive Harley-Davidson factory 6-speed

The 7th gear enables the motorcycle to make full use, by the way of gear ratio management, of the torque and power put out by the 96 ci, 103 ci and 110 ci motors

Unlike the stock mainshaft which includes 1st through 4th gears, the DD7 is lightweight and only includes the small 1st gear, minimizing the shift clunk

Shift smoothness is achieved by use of a new linear roller ball detent which is part of the supplied billet top cover
