Stock 4-Speed N1 Shift Drum
Eliminates the possibility of catching neutral on a 1-2 upshift. A quadriplegic could find neutral on a hand shift bike with the N1 shift pattern. We start with a solid chunk of steel, machine in all the features, then remove the unnecessary material. Two teflon coated bushings are pressed into the drum axis bore for smooth rotation on shifts.
The N1 drum changes the shift pattern from the standard 1-N-2-3-4 to N-1-2-3-4.
Installs into existing 1952-79 ratchet tops with no modification.
