For the 2025 L-TX SE, coded SW1NLSSB, Yamaha's service manual is LIT-12618-04-03. It covers eight sleds in total, adding the M-TX LE 153 to the L-TX GT EPS, L-TX LE EPS, S-TX GT EPS, SRX LE EPS, X-TX LE EPS and X-TX SE.
Since the SE does not have power steering, some of the electrical material in the book belongs to the EPS models rather than to your machine. Model codes appear with those sections so there is no ambiguity about which sled a procedure addresses.
What applies to the L-TX SE is comprehensive: maintenance schedules, engine and turbocharger overhaul with torque values and clearances, fuel-injection and electrical testing, clutch and drive-belt specifications, suspension and track adjustment, brakes, steering and complete wiring diagrams.
