You will need a fair amount to convert, New Pipe, Silencer you can always build some brackets for relocation. Tank, and the conversion kit as a whole. I know they stopped making the conversion kits, so if you can find one that will be your best bet.
Sorry for the slow response... "Race" bike lol, well I have raced it maybe 6 times since I owned it. There are dents in the pipe, the prior owner didn't like Black Rims, because they show scuffs. The newer 2012+ bikes are much larger than the 2011 models.
