Now I bought an aircooled 2t 125 from Piaggio, will bring it to new (around stock) condition (and stock exhaust!!!) and will swap the 70cc Polini engine.
Next step will be respraying and some genuine Rizoma CNC parts.
Bitubo suspension will bolted on too. It's ordered and now shipping to Moscow.
Thinking about bigger front brake rotor, but not sure will it fit or not.
So here's some pix.
P.S. Thanx for your forum, it helping me in my part choice.
