The swing arms should be the same even on the 848. The 848 has a smaller hub but that's all I think. To answer your question, it should fit both.
. Thinking about it, I think that the street fighter and super bike arms are different. Maybe that's where the possible problem is...
early 848 and 1098 art teh same and silver, 1198 same but in black. Streetfighter slight differences as they are about 10mm longer.
I find they need a bit of pressure in certain areas whilst curing the silicon adhesive. Useful to have some of those plastic g-clamp things.
