Description

Polini Primary Gearbox 24/72 Evolution – longer translation for your Vespa Smallframe engine

With the Polini primary gearbox 24/72 Evolution, you get a proven primary ratio for Smallframe setups where you want to run a longer translation and thus more top speed with matching engine power. The 24/72 setup is a true classic in Vespa tuning – particularly popular on Vespa PK as well as classic 50cc/125cc Smallframes.

The Evolution version is designed for precise operation and reliable power transmission – ideal if you are building your engine more sportily and the standard ratio no longer fits your setup.

Features & Benefits

  • Primary ratio: 24/72 (Evolution)
  • For tuning setups: longer translation for more speed potential
  • Clean power transmission: precisely fitting gearbox/primary upgrade
  • Top combination for many Smallframe engines (coordinate sensibly depending on cylinder/power)
  • Brand quality: Polini – known from the Vespa performance sector

Technical Details

  • Manufacturer: Polini
  • Type: Primary gearbox / primary ratio
  • Version: Evolution
  • Number of teeth: 24/72
  • Item number: P202.1221

Compatibility

  • Examples: Vespa PK XL 50 2-stroke (1986), Vespa PK 50 2-stroke (1982), Vespa Special 50 2-stroke (1969)
  • Examples: Vespa Primavera 125 2-stroke (1967), Vespa Primavera ET3 125 2-stroke (1976)
