there are no bolt-on points. You'd have to create places to bolt to - and by then why not just weld on? Triumphs HAVE places already there to bolt a tail section/rear-frame onto. Plus, if you went to the trouble of creating places to bolt to, what would go there if is not a hardtail? it's not like you could bolt a stock tail section back on. XS650 simply isn't made that way. Triumph is.
