Precision-machined to restore smooth power transfer, this aftermarket Variator weight set SYM (20,1×14,8) 11,5g (6x) is specifically developed for the SYM Jet 14 125I 125cc scooter, covering model years 2017 through 2019. Cross-reference OEM number: 22121-MA1-000-A.
These variator rollers (weights) are the centrifugal actuators within the CVT system. As engine speed rises, they move outward in the variator ramps, pushing the movable drive face inward and changing the effective drive ratio for optimal acceleration and top speed.
Technical specifications: Dimensions: 20.1 x 14.8mm | Weight per roller: 11.5g (set of 6: 69g total) | Material: PA66 polyamide with 30% glass fiber | Hardness: 82 Shore D | Operating temperature: -30°C to 150°C
Installation guidance: Install all six rollers simultaneously, never mix weights of different specifications. Ensure each roller sits freely in its ramp without binding. Verify equal spacing and free movement by rotating the variator by hand.
Replace every 15,000-20,000 km as routine maintenance, or when flat spots, cracking, or uneven wear is visible. Heavier rollers improve top speed but reduce acceleration; lighter rollers do the opposite.
This is an aftermarket replacement part, not an OEM genuine component. SKU: SYM-001107.
