There are 3 different frames for the VRSC family. First were the narrow frames for the 180 tire years ('02 to '06). The "R" models had their own frame. Those also had the 180 rear tire but were higher in the rear for the shocks. They were made for only 2 years. Then you have the wide frames for the 240 rear tire ('07 to '17). There have been some very minor changes in the frames year to year but those are the 3 major types.
