Service information for the 2025 UMAX 2 Rally AC, code YUM2E25_UMXS, is Yamaha part number LIT-19616-A3-90.

Four 2025 AC-drive UMAX configurations share that volume. Because they are all electric, the motor and controller chapters carry real depth: winding and insulation tests, controller fault codes, battery pack service, charger operation and harness diagnosis, each with the readings Yamaha expects.

Also covered

  • Brake and parking brake adjustment
  • Steering and suspension overhaul
  • Rear axle and wheel service
  • Body panel removal
  • Torque tables and wear limits

Confirm YUM2E25_UMXS against your vehicle identification, and keep the part number with any parts enquiry so the listing and the procedures match each other.

Yamaha built these cars so the pack and controller come out as units, and the manual gives the removal order along with the isolation steps that come first. Wiring diagrams are reproduced in full for the model year.
