I need more DS bike under me (6' 5" 250lbs) than my KLR can provide. So I am gonna gift it over to my son--and was thinking to go up to a F800GS. But in scanning Atlanta craigslist ( I live in SW GA) I see what appears to be a fairly rare R850GS for sale. Any input from the collective wisdom on this bike--other than don't dick me over an buy it out from underneath me if I've stumbled on a good deal! /r
