SYM, short for Sanyang Motor, was founded in Taipei, Taiwan, in 1954 by Chang Kuo-an and Huang Chi-chun. The company grew into one of Taiwan's largest vehicle manufacturers, producing scooters, motorcycles and other vehicles, and today it operates major production facilities in Taiwan, mainland China and Vietnam while selling its products in markets across Europe, Asia and beyond.

SYM scooters are respected for practical, reliable design and strong value, and the range includes popular city models such as the Mio and Symphony, sportier machines in the Jet line, and larger touring scooters such as the Maxsym. Decades of experience in demanding Asian markets have made SYM a genuine specialist in small-displacement engineering, and its scooters are common sights on European streets.

The workshop manuals in this section cover complete engine service and overhaul, transmission and variator work, brakes, suspension, fuel and ignition systems, electrical and wiring diagrams, torque specifications, diagnostic procedures and the scheduled maintenance SYM specifies for each model. Procedures follow factory practice step by step, and every section gives the measurements, clearances and settings needed for the exact model and engine fitted.

They are useful for DIY owners who maintain their own scooters, independent garages that see growing numbers of SYM machines, and anyone who wants factory-level documentation rather than generic advice when repairing these popular Taiwanese scooters correctly. Owners who have the right manual can tackle jobs with confidence, and workshops can quote and complete repairs accurately the first time.
