NCY variator slide pieces (set of 3) for 50cc 4-stroke scooters with 139QMB-based engines — black plastic C/U-shaped sliders with notched engagement slots that replace the stock ramp plate slide pieces in the front variator pulley assembly. Sold as a set of 3. SKU: 1200-1186 | MPN: 675A17DIORLL.
Variator slides are the guides between the variator pulley and the back plate. These are commonly overlooked during service but wear gradually and can cause excess noise and a loss of CVT performance and acceleration. Inspect and replace whenever servicing roller or slider weights.
