• Covers 2002–2006 Honda CG 125 Titan, Cargo, and Fan variants (including KS, ES, KSE, and regional models)
• Official 100-page Honda factory publication (P/N C4085-91017, dated November 2005)
• Features 12 wiring schematics, 27 detailed torque tables, and full exploded-view illustrations for engine and chassis systems

Having exact factory specifications on the bench cuts down diagnostic time significantly. This reference manual maps out the mechanical baselines, maintenance procedures, and system-level diagnostics for the 2002–2006 Honda CG 125 series. The material covers routine upkeep, lubrication protocols, and fuel system operations. It also includes specific technical data for valve clearances, air filters, and engine oil across all variants.

You get direct access to the exact clutch, transmission, and crankshaft assembly sequences. Factory routing diagrams for cables and electrical harnesses simplify complex electrical troubleshooting and reassembly jobs. The manual also outlines emission control system configurations specific to the Latin American and Brazilian markets.

Specification and Reference Data

Critical values for chassis maintenance and engine assembly are laid out clearly for quick workshop reference. Standard engine oil capacity is 0.8 liters for routine changes, increasing to 1.0 liters after a complete teardown. Normal engine compression testing should yield 1,324 kPa.

Intake and exhaust valve clearances are both specified at a tight 0.08 ± 0.02 mm. During reassembly, getting the torque right is critical. Cylinder head nuts require 32 Nm, while the flywheel bolt takes 74 Nm. Skipping or guessing these factory tolerances can lead to mechanical failure and compromise rider safety. Always follow the manufacturer's exact torque sequences and procedures when turning wrenches on these bikes.
