Hmm... not sure. My dad has a 90 SC and I am pretty sure it does not have one since I've seen it at around 240km and that was only when I was in it. He already broke the speedometer on it. It tried going all the way around and it got stuck on the distance reset and broke the spring on it. =) Now that is fast. lol But I am not sure about yours or the newer ones.
Go to
