Product description

The DRT Primary Gear with 65 teeth was developed to lengthen transmissions of large frame Vespas built from 1960 on up to 125/150 cc PX models. The DRT gear has a larger diameter than the PX200 primary 65, and matches the original. It's a perfect fit for all clutch gears with 20/21/22 teeth, though not with the PX200 clutch with 23 teeth.

SIP-TIP:

  • Tried and tested: the combination of longer 4th gear w/ 33 teeth and short primary (65-20) or 4th gear DRT 36 teeth with a 21 or 22 toothed clutch gear.
