45 W 4-Speed Transmission Gear Assembly Unit
Before you order — V-Twin tech note
Description
100% brand new components assembled in our New York V-Twin Motor Shop. Assembly includes replica cast transmission with left side race installed. To view the full assembly see our entire production video on YouTube! Assembly also includes clutch hub nut, clutch throw out bearing and 17 tooth transmission sprocket. The case is a natural finish, top cover is parkerized, and the right side door is black. Assembled with the sprocket cover, clutch arm and shift linkage. This 4-speed transmission comes completely assembled with all gears, shaft and covers intalled for a quick straight-forward installation. It accepts original primary drive with clutch and the chain sprocket cover. Looks the same as a 3-speed unit, the only extra part required is a 4-speed shifter gate. The original 3-speed transmission has a large gear ratio difference between 1st and 2nd, (2.47 to 1.57:1) with a consequent big rpm drop. The 4-speed version with its extra gear allows you to stay in the power band, which is much better for performance. The shift pattern is: 1st gear is forward, neutral, 3rd and 4th gear are back towards driver as seated on motorcycle.
