Description

Keep your automatic scooter shifting smoothly and efficiently with the premium Bando 669×18×30 CVT Drive Belt (106-111). Manufactured in Japan to meet demanding OEM standards, this belt is engineered specifically for 49cc/50cc 4-stroke QMB139 short-case engines with a 10-inch rear wheel. Constructed with high-modulus synthetic rubber compounds and high-tensile cords, this belt resists heat stretching and structural deformation under continuous high-RPM loads.

Short-Case Fitment Note: This belt measures 669mm and fits short-case 50cc GY6 configurations with a 10-inch rear wheel only. If your scooter uses a 12-inch or 13-inch rear wheel, it has a long-case engine and requires a 729mm or 788mm belt instead. Always verify your stock belt size marking before ordering.

Key Features

  • Premium Japanese Manufacturing: Engineered by Bando to exact factory replacement standards for consistent geometry and long-term durability.
  • High-Tensile Cord Reinforcement: Minimizes longitudinal stretching and decay under high thermal loads within the CVT case.
  • Short-Case 50cc Direct Fit: Sized for 139QMB / GY6 50cc 4-stroke engines with 10-inch rear wheel layout.
