Hey all, I'm on the road to converting my old 1975 Honda PC50 into a cafe racer.
This is what I've drawn up to far, give me some ideas on what I should customize and ideas on the colour scheme!
It depends on your fabrication skills tbh and whether you're doing it for the right reasons I guess. Yer you could do it, sure, but the question is should you. You certainly won't make any money off it, but if you've always wanted a sporty moped... go for it
Can you build a street racer moped? I suppose it is possible. People raced mineralli's, Garelli's, Derbi's, Kriedlers, honda mb5s, kawasaki Ar50s, et al. However, just like real bikes it pays to start with the right platform. Ig you are doing this to a Honda Hobbit or a vespa ciao, then the best way to convert to a racer is to sell it and use the money to buy the right platform.
Larrybones used to have some really neat hot rod puchs, but again he had aftermarket support for those bikes and knew what and where to source good parts (like campagnolo light weight wheels from other models and stuff).
building a racer is more than just bolting on a seat and top tank and some bars. Like anything worth doing it requires research and planning your modifications. Making poorly done pen and ink renderings to figure out "colour" scheme at this stage is just stupid. If you look at the mopeds people are racing today in vintage classes, a lot of them have mods that are more in line with real GP racing motorcycles of the era, this isn't just add a top tank and low bars proposition.
I had a hard time keeping up with this in brooklyn traffic on a real motorcycle. For the first 50 feet of any stop light he would obliterate anything in his path. If you are seriously considering a moped, sell whatever you have now and buy a puch magnum with a top tank. The other one I would look for is an FS1E "Fizzie". Tons of aftermarket and hop up tricks and again another top tank bike from the factory.
