The 848 nose dosn't lend it's self to fit as the 748/9** dose it relies on the side panels & 2 fixings near the screen the 748 one has 4 fittings to the nose cone, but anything can be made fit.
I had full 848 fairing, but the bracket would have allowed me to run just the nose on it's own. It mounted to the sides of the screen, with a third arm down to allow a fixing to the bottom centre of the nose (there is a flat section there). Mine was fabricated by Dave Wood at DWR in Aylesbury... He can make up whatever you want.
