Andrea Pinasco was one of the first mechanics who successfully tried to improve the performance of classic Vespa scooters, and his company Pinasco consequently became one of the household names for Vespa tuning. Carburetors, cylinders, exhausts, crankshafts - everything to make your vintage Vespa run better and faster.

Pinasco Cylinder Kit 85cc cast iron (d=50mm / 43mm stroke) Vespa V50 / PK50, classic 75cc cylinder. It is a cast iron 'Big Bore' (50mm) cylinder that will increase displacement up to 85cc while allowing to retain the original crankshaft. The cylinder is extremely dependable, with a long service life. Performance is not over the top, but reliable with a noticeable increase in top speed, and there is always the option of modifying the ports to get more out of it.

The robust cast iron cylinder with 2-ring piston is an excellent choice for original or close to original setups. Easy to mount. We recommend checking the condition of your crankshaft and bearings before mounting.
