Yamaha catalogued the service information for the 2018 Sidewinder line under a single part number, LIT-12618-03-50, and that is the book covered here. The machine it is bought for carries model code SW1NML53JL, stamped where the chassis identification appears, so fitment can be confirmed before any work starts.
Because the factory wrote one volume for the whole 2018 Sidewinder range, the same procedures serve the M-TX LE 153 alongside the L-TX DX, L-TX LE, L-TX SE, M-TX 153, M-TX 162, M-TX SE 153, M-TX SE 162, R-TX SE, R-TX LE 50th, S-TX DX 137 and 146, B-TX variants and the X-TX SE 137 and 141. Where a specification differs between those models, the text calls out the code it applies to.
Inside are the disassembly and reassembly sequences, torque values, clearance and adjustment figures, wiring diagrams and the diagnostic charts the factory technicians worked from.
