This relates to an 07 FE550E. Upon initial fitment it looked good, but I noticed the axle now projected farther into the axle nut. Careful measuring showed a difference in the axle boss thickness. The Husaberg caliper mount measures 20mm wide. The Scotts/KTM caliper mount/sharkfin measures 18mm wide. Thus the swingarm is pulled in by 2mm when the axle nut is tightened.
This difference is on the outboard side of the caliper axle boss. It is apparent when looking at the space between the inside of the left swingarm and the caliper mount. Stock there is 1mm between the mount and the plastic swingarm hole plug. With the Scotts unit in place, the caliper mount presses against the the plastic plug.
I machined up an aluminum washer 20mm ID x 38mm OD x 2mm thick. With this between the Scotts caliper mount/sharkfin and the left swingarm, everything lines up properly.
