I have a 2012 xciting 500Ri and ordered the SR91, On the paper diagrams it shows "Kymco Xciting R 2009 300i-500i". I also had the SR92 sent to me when I ordered for the 300 i had and it listed on the diagrams "2009 125-300 cc". I found that the (2) spacers included in the SR91 were too long for the mounting to my 500. So, fortunately, I still had all the hardware from the 300 (SR92 kit) and the shorter spacers were just right for the mounting. The spacers for the (SR91 kit) shown on the diagram are "016x50mm--Foro 08,5mm, V502. The spacers in the (SR92 kit) list 020x35mm, V250. These figures are taken right from the diagrams from both mounts. If I may add a WORD OF CAUTION. When you are taking out the long mounting bolts to replace them with the kit bolts, loosen both but only take one at a time out, being you will get a shift of the holes if you take both out at once and will have a problem lining up for the new bolts to secure with. I did everything with mine other than connecting the holding brackets to the upper shock mounts being I didn't have the correct tools or the know how to do that. If the new spacers are too lond as were for me and you can't get 2 spacers as I had from another kit, you may have to cut them down to fit. FURTHER: if you can order the (2) spacers from the (SR92 kit), they are listed as part #7, Q.TYn.2).
