on a 250 2 stroke, vibration is insane, i'd ride for 2 or 3 laps and i was cramped. once i put this on my bike it doubled my endurance. must have for any 2 stroke rider. ktms also have pretty useless design for the bar mounts, my cousin twisted his and i twisted mine, i'm yet to see how this holds out, but it seems like a very tough part and i'd expect it to take a pretty good beating.
