I have seen a few of these small engined choppers going around, maybe 100-200cc engines, but with substantial rake. Any idea where I can find these bikes, I presume they are from a specialist as I've never seen such dramatic small bikes before. They look like a great project to play with, pimp out.
There are a bazillion out there. Google "mini chopper" or "pocket chopper." Most are 50cc.
They are toys, really, with little practical transportation value in the DR.
Learn some good welding skills, because you'll be needing them. Rake may look cool, but it weakens the front end, the yoke bearings and the forward part of the frame ahead of the CG. Choppers, especially mini ones, aren't built for strength...
Used to own one. Sold it and I think it is still on the road in Cabarete. 50CC motor.
Generally speaking it is CCC (no not Chris Colon) but Cheap Chinese Cr@p..
I have been riding a china knock off of a yamaha virago 250 for the last 3 years,about 20,000 miles so far. Not had much trouble with it, if I do all yamaha parts from ebay fit. Great little bike imo. Look around as they are imported under various names.
