I have RC Components on my Raider, they are 8.5" There is no problem with clearance on the brake side and I run a Avon 240. I can't tell you if there is an additional spacer or shim, the wheel was put on at the dealers when my bike was being built. At one point the dealer had put a 250 on by mistake and it still cleared but just barely according to them. bhodge, a member here and the General Manager at Tejas Motorsports could tell you if a spacer or shim is needed. Send him a PM.
