Replacemen drive belts for Minarelli based scooters, Yamaha Zuma Bugeye and Prebug. These are for standard Minarelli and will not fit short case, or long case. Fits most Aprilia mina. motors, SR50, Scarabeo, Rally.
Choose from standard or Kevlar. Standard is good for builds in the range of 10 or so HP, Kevlar is necessary for engines pushing 15+hp. Kevlar belts will tend to slip more than standard so a stiffer contra spring is required.
