I'll offer a differing opinion. Fitted a HT to the rear of the 690 before last years KTM Tas rally. Day 1, ok. Day 2 onwwards, ie once it had lost its edges, it was just plain horrible on anything other than dry bitumen. No grip, no traction. Sand, maybe due to the paddle shape of the centre lugs. Gravel or rock, crap. Hardpack, garbage. Anything damp, forget it. Pure shite IMHO. Each to their own though I guess.
