Bidalot Racing Factory Transmission Kit Derbi Euro 3 (D50B0), complete high-end primary transmission by tuning specialist Bidalot.

This complete transmission with clutch and primary gears by Bidalot Racing Factory will reduce clutch slipping, especially in larger displacement engines with lots of power. Gear ratio of this transmission differs from the original - taller gears reduce the overall gear ratio, smaller gears increase it. Maximum input shaft rotation will kick in more quickly so pressure on the clutch is reduced to improve clutch grip and avoid slipping. In addition, the clutch basket is made of solid aluminium which allows for mounting 6 discs instead of only 4. Clutch slipping is avoided and all available power is transmitted to the wheel.

The kit includes:

  • primary gear 21 teeth
  • primary gear 64 teeth
  • water pump gear
  • pinion for counterbalance shaft
  • 2x needle bearings
  • clutch basket CNC-cut
  • clutch bell CNC-cut
  • pressure plate
  • 6x friction plates + 5 steel discs
  • 5x racing clutch springs
  • screws
