No Tim, haven't been down that route (yet!) although my first thumper apart from a Honda C70 was an '87 Yamaha XT350. It went well as I recall although not the most comfortable for the longer trips. One two-up trip to the Waterford Custom bike bike show still brings back painful memories! And my SR500 is a very different beast as well - I haven't used it much over the last couple of years though so have decided to sell it after many years. Will post details soon.
Regards
Tony
