Smallframe 200cc
Well this looks interesting. Quattrini have just released a 200cc cylinder kit for Vespa smallframes. 67mm bore x 56.50 stroke. The kit uses a special crank and uses a version of their crank cases. Prices don't look too bad either compared to what else is out there. The kit is £490, the crank is £325 and the crankcases are £516. It also has a matching exhaust but it is as ugly as sin.
Incase you or anyone else is intrested I know of a German lad doing bespoke cranks of upto 60mm stroke for smallframe motors.
I also know of a few German lads playing with Paraglider barrels on smallframe cases.
