If you need further information the J-Rod doesn't have try hitting up 400greybike.com or customfighters.com. The customfighters has a lot of the SSSA dimension, I also have an NT650 currently in my possesion if you need dimensions off of it. Be prepared to do some custom shock linkages/mounts, brace the swingarm pivot area and add plates for the new swingarm pivot bolt and so on. It's alot of fun and looks cool when done, especially with the single nut wheel, might even be able to get the older RVF/VFR 18" rear to fit that axle with minor work to keep a stock wheel size looking appearance! Hope this helps and good luck with the sale J-Rod!
