Description
DR PULLEY SCOOTER SLIDING ROLLER CLUTCH CVT WEIGHT ( 21*15*17.5G APRILIA SR160 )
Unlock smoother, stronger acceleration and a higher usable top‑speed band on your Aprilia SR160 with Dr. Pulley’s patented Sliding Roller Weights (21 × 15 mm, 17.5 g). Unlike conventional round rollers, these precision‑molded sliders glide along the variator ramps, minimizing friction and keeping the belt at an optimal drive ratio for longer. The result is crisper throttle response, reduced RPM “flaring,” and improved overall CVT efficiency—ideal for spirited city rides or weekend performance tuning.
