As the k6 is my first sv and first real bike (I had a MZ hair-dryer before, but i was mostly trying to get that to move, rather than to slow down) I couldn't really tell you, I've been told it has great engine breaking, but its all ive seen, so can't really tell. you never know, your bike may have just been delivered with the correct TSP level
see here, apparently that reduces the engine breaking, but makes up for it with tht extra kick at low revs.
