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 177cc cast iron 57mm stroke Vespa PX 125cc, relaunch of Pinasco's classic 177cc racing cylinder. It is a cast iron 'Big Bore' (63mm) cylinder that will increase displacement up to 177cc while allowing to retain the original crankshaft. Port timings are designed for racing, with excellent power and impressive torque throughout the entire rpm range; with great torque already available at low rpm.

The cylinder is made of hard-wearing cast iron and comes with a 2-ring piston and a special cylinder head with central spark plug. The cylinder is basically plug and play, with a sufficient increase in power for those who do not want to invest money, time and effort into tuning projects. There are, however, options for modifications and upgrades.

We recommend using a reinforced Pinasco crankshaft with 57mm stroke.

  • cast iron cylinder
  • 2-ring piston
  • HC cylinder head
  • gaskets
