So I have just gotten into the world of moped after owning a '59 Lambretta Series 2, '65 Vespa Super (with a P200 motor w/ racing exhaust), and a '65 Honda CB160. I know with Lambs and Vespas when all kitted and tuned up you can damn near top out at 100mph (and cruise at 60-70mph)
I have been researching motors and kits and it seems like the biggest kit you can get is a 77 or 80cc kit. How fast can a kitted/tuned moped go?
P.S. what I really loving about custom mopeds are that you can build them into hard core vintage cafe racers which is 100x cooler than a Vespa. I just wished I knew about this 5 years ago..HAHA
