Description

Dr. Pulley 19x15.5mm sliding roller weights for Vespa, Piaggio, and Aprilia 4-stroke 50cc scooters. The patented sliding shape allows the variator to open wider and close further than standard round rollers — delivering faster acceleration off the line and a higher top-end speed. Available in 5g through 9.5g to match your riding style and modifications. Sold as a set of 6.

Features

  • Broader gear ratio: Belt sits lower at start-up and higher at top speed than OEM rollers allow
  • SL-9 self-lubricating nylon composite: Heat-resistant, low-friction, eliminates flat-spotting — no grease required
  • Wide weight range: Available in 5g–9.5g (0.5g increments) to tune acceleration vs. top speed
  • ISO 9001 certified | Made in Taiwan
