hello lapman here,
When I did the mag swingarm fitted, I also had the mag triple clamps fitted as well, and a new rear spring better suited to my weight. a nimble 13st 7lb....
Both bikes had the corse floating rear disc with the corse rear brake and axle, looked flash but was ****, barely passed the MOT.
As with all things Ducati, you have to use racing lightweight wheels as the standard 5-spokes hit the rear brake!
Never had a problem slow steering on the 853 or the 998R.
I've found a picture of the 853sp i'll try and post it later.
Must be time for a "where are you now" type thing.
