Retrofit variator springs are an important and intelligent purchase when tuning your automatic scooter. Why? Horsepower hefty motors tend to outrun their belts. In order to keep the herd from stampeding, a reinforced vario spring exerts pressure on the rear fan belt half; belt is held tighter - making it harder to slip and slide. Motor tuning without reinforced vario springs is about as successful as snowboarding in Miami.
