i seem to remember an 848 track body kit on a monster (for a DD track bike) that looked great think it was done by dave woods DWR in aylesbury you would need to work out how to make the lights etc fit etc for the road tho i dont know if radical ducati nose units are still available mad by someone else under license but these could be an option if you want some extra wind protection
FE is mostly right, in that the later water-cooled frame is the same as the ST4, but... There are no fairing tabs welded on. So, I think the answer must be 'no, not without a welding torch'.
