SPEEDOMETER DRIVE BOX 1.25-1 (15/12) RATIO - 5/8 (.625) AXLE HOLE - LF HARRIS (150 mph gauge)_x000D_
Speedometer drive box, 1.25-1 (15/12) ratio, 5/8 in. axle hole, for use with a 150 mph gauge.
This is a speedometer drive box, the small gearbox that takes rotation off the wheel or gearbox output and sends it up the cable to the speedo head. The listing on this one calls out a 1.25-1 (15/12) drive ratio and a 5/8 in. (.625) axle hole, so it's built to suit a specific spindle size and gauge calibration rather than being a universal fit.

The box is noted for use with a 150 mph gauge, which tells you it was matched to a particular speedometer's calibration rather than being a generic drive unit. If you're replacing one of these, the ratio and axle hole size are the two things to check against what's coming off your bike before you order, since a mismatch on either will throw your speedo reading off or just not go together mechanically.
We don't have much more history on this one in our records beyond the drive specs listed. If you're not sure this is the right box for your setup, give us a call and we'll help sort it out before you buy.
