2022 Yamaha TRANSPORTER LITE 2-UP Service and Repair Manual

The two-up version for 2022 wears the code TRT4NNB, and the manual written for it is LIT-12618-03-89.

Yamaha covered four machines from that season in one book: the 2-UP, the standard TRANSPORTER LITE, the SXVENOM and the SXVENOM MOUNTAIN. Most of the service work is shared, so it appears once, and the codes mark the procedures that belong to a particular model.

For the 2-UP specifically, the code is worth confirming before you order parts, because the machines look and number similarly enough to cause mistakes at a parts counter. Once you have matched TRT4NNB to LIT-12618-03-89, the rest is ordinary dealer-level material: specification tables, torque figures, service limits, assembly sequences, wiring diagrams and the factory's structured approach to diagnosing a fault.
