I don't know if you found one yet.
I found two.
Earlier a bought a clone of a honda Trail CT70.
Mine is a 90cc 4speed, but you can get as high as 160cc.
The kind with the folding handlebars. It fits in the VX

Yesterday, I came home with a Suzuki Intruder.
11k miles on a 1997 with 1400cc (70hp)
It's a beautiful beast
