Frame-wise, you're thinking same as me Curt. Reckon that's a nicely modded Cantilever frame. Interesting to see the makers of the Fuki Planning also sell the gas tank separately. Two tank capacity options (2L & 1.5L) available.
Yeah the 125s, a friend has a Chinese one we can mess around with. Manual clutch, might be a 4 speed. I have ridden one of those 125cc choppers as a semiauto with optional suicide shift.. they are comfy and ride OK. So many potential projects, so little time.Pete I'm currently parked on several projects , but still investigating others out of curiosity that may never see light of day. I feel you do the same this being an example. That said the insights gained may influence a future build.
Norm is absolutely correct 33cc won't get it done in the U.S. on gas I like the 99cc to 212 Predators or Honda clones or originals. With 12 to 15 hp my 5 speed 125cc Honda clones have speed enough for highway use if mounted on DOT rated tires and wheels. Quite a few 2 strokes CG 66cc bikes making 5hp and some closer to 10hp so yeah right or wrong that's where I'm at.
On electrics 5 to 10hp is common and my current build (pun is obvious) a lightweight aluminum Schwinn straight bar frame and 48v. 5 hp mid motor and V twin case will weigh about 60 lbs.
Power is a big deal with a lot of us though I admit it leans more to moped or cycle than bicycle, yet still looks a bicycle.
