Another great CT90 build. I have got to get me one of those. I currently have an '80 Puch Newport II with the original ZA50 2 speed engine. It tops out at 30 mph on level ground, but with the low first gear, it will climb anything while keeping the engine speed up. I have a nearly new E50 single speed motor for it if the ZA50 ever blows up. But I want something small, with better suspension, that can reach at least 55 mph on a level road, with a manual transmission so I can ride it in the mountains without lugging the engine like on a 125cc CVT scooter.
