Yamaha's 2019 Sidewinder service manual is part number LIT-12618-03-55, and it was written to cover the whole model-year lineup in one volume. The B-TX LE 153 is coded SW1NBLKY.
The other 2019 Sidewinders documented in the same book are the L-TX DX, L-TX LE, L-TX SE, M-TX LE 162, SRX LE, X-TX LE 141 and X-TX SE 141. Chassis, engine and electrical work is largely common across them, while track length, suspension calibration and equipment differ, and those differences are called out by model code.
Content is the dealer material: periodic maintenance, engine overhaul with torque and clearance specifications, turbocharger and fuel-system procedures, electrical testing with expected values, clutch and driveline, suspension and track setup, brakes, steering, wiring diagrams and troubleshooting. Confirm the code above against your sled before ordering.
