You can covert it to street use but it is sketchy getting it done. there are a coupleof shops aroundthat will help you. The r does not have any sort of warranty, so the infamous flaking rockers will be paid for by you. also, there is a lot more stuff that can go wrong on this bike, its in a high state of tune. I was looking at one and the dealer who i know said it would not be good for me on the street. If you are a rich dude, who will only do 2 or 3k miles a year go for it, but if you are an average guy who likes to ride, this may not be the best bet.
just my 2c
