8)three reasons, one is that the stock rev limiter on an 883 is 500 rpm higher than on a stock 1200, i thought the 1200 and 883 had the same cams but 883 must have a different cam that gives it more low end power. The main reason is that the insurance company sees the bike as an 883:snakeman: and will charge me insurance for an 883 not a 1200. Im 18 and they think they need to get a small fortune off me for insurance if have a 1200. Plus when I put a 1200 kit in i want to do some head port work anyway
