I do not think the Turbo S has engine braking, but on my first ride in mine (used to ride a 900 S), it sure felt like it coming down steep muddy hills. The back end kept wanting to slide out front. I tried going down one steep hill in neutral and found that was not a very good idea. The 900 S, I could get the engine/clutch to engage going down hills by tapping the gas a little bit. This one seems like it never lets go. Belt is new and all seems just fine otherwise with the clutch. Is this just how the Turbo S does hills?
