Polini is one of the big names in 50cc scooter tuning, and is also one of the leading manufacturers of tuning parts for Vespa, modern and vintage. Cylinders, intake manifolds, exhausts, air filters, carburetors, crankshafts and more - everything you need to boost the performance of your Classic Vespa.

Polini Cylinder Kit 135cc (d=57mm) with Intake Kit for Vespa 125cc Primavera, HQ racing cylinder by Polini.

This extremely powerful Evolution cylinder is a direct intake cylinder, mounted directly to the carburetor; the kit includes a reed valve. Performance is convincing in every way - powerful, efficient, reliable, stable.

This cylinder kit is compatible with all 125cc Vespa models; it has to be combined with a long stroke crankshaft (Polini, art. no. P210.0034). 57mm diameter and 52.8mm stroke will add up to a total displacement of 135cc.

Port timings are designed for racing, with 6 Nikasil-plated transfer ports. Exhaust port and cylinder head design improve the quality and quantity of air flow leading to optimum performance. Extra cooling fins provide appropriate cooling for a powerful engine like this. The single-ring piston has a low-friction coating.

The cylinder kit comes with cylinder + cylinder head, reed valve with 6 carbon fibre petals (0.4mm thick) and an intake manifold with large diameter for PWK 24 - 28mm carburetor. For optimum internal cooling, we recommend using it with a 24mm, 26mm or 28mm carb; a special exhaust is also recommended if you want to exploit the full potential of this fantastic cylinder (Polini P200.0291).

  • cylinder, cylinder head, piston, gaskets, reed valve, intake manifold
  • Nikasil-plated aluminium cylinder + high-compression head
  • 130cc displacement
  • long thread spark plug
