A while back, I started looking into building a motorcycle. I got the information from the state on what paperwork would be needed for registration, but I get the feeling I'm missing something on what is necessary for a motorcycle to be street legal. Digging through the internet doesn't seem to help, since state laws seem to vary on motorcycles. What I've found is:
Over 125cc is a motorcycle.
125cc and under is a motor-driven cycle. Motor-driven cycles are not legal on the interstate (I would think it's crazy to even try the interstate on something that small).
An operating headlight is required and must be on at all times on the street. Taillight, brake light and turn signals are also required (is there a minimum distance between the turn signals?).
A mirror is required on the left handlebar.
There is a maximum height for the handlebar grips to be above the seat (no ape hangers).
Am I missing anything? I couldn't find any mention of a minimum seat height, which seemed a bit odd, considering the ape hanger restriction.
