KYMCO Variator Rollers: Roller Weight Sets by Model

KYMCO variator roller weight sets by model: OEM part numbers with set counts and gram weights, plus how rollers change acceleration and top speed.

KYMCO People S 200 (2008) E05 Driven Pulley parts diagram

KYMCO variator rollers (the factory calls them roller weight sets) are what turn engine speed into forward motion on every belt-driven KYMCO. As the rollers wear flat, the variator stops shifting cleanly: take-off gets jerky, cruising RPM creeps up, and top speed drops even with a fresh belt. This guide lists every OEM roller weight set in our catalog; the set size and gram weight are part of the factory name (for example “1SET:6PCS 6.5G”).

Stock weight or tuned weight?

The factory gram weight is chosen for the whole package: belt, clutch spring, and engine torque curve. Lighter rollers give snappier acceleration but raise cruising RPM and fuel use; heavier ones do the opposite. Fit the OEM weight first: if a worn set was your problem, stock rollers restore the machine to how it left the factory.

How to confirm fitment for your exact model

Model names repeat across years and regions, so the safest way to order the right roller weight set is to confirm it on your model's own diagram:

  1. Find your machine. Pick it on the All Models page, or decode your VIN with the VIN lookup to land on the exact model year and colour.
  2. Open the diagram. The exploded views mirror KYMCO's factory fiche; the diagram cards on this page show which drawing the roller weight set sits on.
  3. Match the number, then order. Check that the number on the diagram matches the row in the chart, then follow it to the product page on kymcopartsstore.com, where the part is ordered.

If a part number has been superseded, the product page shows the replacement, so you always receive the current factory part.

Find your KYMCO and see every part on its drawingType your VIN or pick the model, year and colour, then click the part on the factory diagram.

Replace rollers and belt together

Rollers and the drive belt live in the same case and wear on the same schedule. If one is due, the other usually is too. While the variator is apart, check the slide pieces (the plastic guides that rattle when worn); they cost little and cure most variator clatter.

Service specs by model

For one machine's battery, plug, oil, belt, torque figures and service intervals on a single page, open its service sheet:
