This new engine kit from Italian manufacturer DR takes small frame Vespa models from 90 or 125cc up to a mighty 135cc for a kick of extra torque and power. It has a 57mm bore with seven transfer ports, and the kit includes the cylinder, head, piston (including rings and pin) and gaskets. It will fit motors with a 51mm stroke crank that use a 15mm gudgeon pin, and if you are transforming a 90cc motor you also need some longer studs and a revised cowling. SRP is £152.
