Cool, I've often thought that if my GS ever got relegated to purely offroad duties, I'd do something similar. Thing is, it'd have to be really high miles/scraped up and massively devalued that it WOULDN'T make more sense to sell the GS in road trim and buy something dedicated to offroading, even something comparatively pricey like a KTM 690 or Husky.
Don't get me wrong, I love the GS and know they are great offroad (for the type of bike they are), but if I was going to sacrifice range and slab comfort, I'd probably go for something that was already offroad dedicated.
Oh and not having hand guards on a bike like that is mental, IMO.
I like my bike because I can overtake 4x4s down farm tracks with a week's worth of shopping on the back.
