Variator rollers 16x13 mm

Has your scooter lost acceleration, does it struggle up hills, or does the engine scream without the speed increasing? Or have you tuned it and want to match the transmission perfectly? These high-quality 16x13 mm variator rollers are an essential component responsible for the smooth and efficient operation of your scooter's automatic transmission (CVT).

Rollers are the key element that regulates centrifugal force in the variator. This 16x13 mm format is one of the most popular in the world – it is used as standard on many Chinese 50cc scooters, as well as in sport Malossi Multivar or Polini Hi-Speed variators.

Key advantages of these variator rollers

• Very precise weight calibration: Each roller is made to a very precise weight (in grams), which ensures perfect transmission balance, prevents unwanted vibration and guarantees an even rise in engine revs.

• Low-friction, heat-resistant coating: The outer shell of the rollers is made from a special self-lubricating nylon or polymer blend. This drastically reduces friction in the variator ramps, prevents early roller wear (flat-spotting) and extends their service life.

• Resistance to flat-spotting : A quality internal metal core and a tough outer plastic stop the rollers developing flat edges. The rounded edges let them roll smoothly along the ramps, keeping the scooter's acceleration steady.

• Universal compatibility: These rollers are great for both standard factory and sport (tuning) variators.
