bearings and speedo drive

Dave, we actually use a double row bearing on both sides of the front wheels. This type of bearing will handle the angular loading that a sidecar rig wheel gets. The left side bearing on the 1100/1150 wheels and both bearings on the 1200 model is the same special item that BWM uses for the upper fork bearing on Oilheads.
To recalibrate the speedometer while using these front wheels, a R1100RT speedo drive must be used. This is a direct replacement on both 1100 and 1150 models. Obviously the speedo drive is not an issue on the 1200 model as the drive is not on the front wheel.
