I have been reading these builds for about a year and like everyone else, I think: Man that is a good idea or I wouldn't do that. Let's face it, the BMW GS is a street bike and although the old Yamaha DT 250 was hell of a trailbike, it was limited on the road! As you move up in size and cc there should be a point where it all balances. The Versys and V-strom are good starting points but the KLR with the 650 twin engine offers more. My question is: If you were to build frankenstien, what would it include and why? I think we need some guide lines, it must be capable of 200+ miles on a tank of gas, comfortable enough to ride 600+ mile days strung together (ie. Touring), keep up with highway traffic, nimble enough to ride single track.
