Electronic or mechanical speedo?
Anyone know if the 87 Formula has an electronic or mechanical speedo? I have the 80 mph, and am looking for a 140 mph, but I think most, if not all of the 140's are electronic.

Yeah, it is an 85, I just said 80 because that's the last numerals on it. Thanks for the reply.
