the 150/70 TKC will fit, but Pirelli MT60R's ought to be enough for simple muck. Mine has lowered pegs and an Ohlins shock. In my opinion, the front suspension needs help even more than the rear. I went with Race Tech cartrigde emulators and new springs. It is limited on ground clearance and the exhaust header is vunerable until someone builds a bash plate for it. The low CG makes it feel much lighter than it is.
