2004–2010 Honda CBR125R Owner's Manual (P/N 61CM000C)

• A 426-page PDF set pairs a 33-page CBR125R Owner’s Manual with a 393-page Honda Common Service Manual: model-specific owner maintenance alongside general Honda repair procedures.
• CBR125R maintenance covers oil changes, spark-plug service, clutch-cable adjustment, throttle and idle checks, and drive-chain inspection and adjustment.
• General Honda engine procedures cover compression and leak-down testing, valve-guide and valve-seat work, and cylinder, piston, and ring inspection.
• The general cooling chapter explains radiator-cap and system pressure testing, thermostat checks, coolant replacement and air bleeding, and water-pump mechanical-seal inspection.
• Chassis repair in the Common Service Manual extends to hydraulic brake bleeding, caliper and master-cylinder service, fork disassembly, and steering-bearing work.
• General electrical troubleshooting charts address charging faults and no-spark conditions, supported by ignition-coil tests, starter-motor inspection, and starter-clutch checks.

CBR125R Coverage and Manual Scope

The model-specific material covers the carbureted, 124.7 cc four-stroke CBR125R. An archived MHT Workshop SpecSheet identifies the 2004 CBR125R4, VK6AB carburetor, and frame reference MLHJC34A*45~. The owner’s manual uses E, F, and ED designations for the UK, France, and European direct-sales markets.

The Honda Common Service Manual, P/N 61CM000C, September 1988, explains service methods used across Honda motorcycles, scooters, and ATVs. This set is not a dedicated CBR125R workshop manual. The general repair chapters call for model-specific specifications and procedures where the design requires them.

Component and Systems Documentation

The owner’s manual provides a maintenance schedule and crankcase-breather service information. CBR125R coverage also reaches front and rear wheel removal and installation, brake-pad wear checks, and the side-stand ignition cutoff check. Seat and middle-cowl removal instructions support access for routine maintenance. Electrical maintenance covers sealed-battery removal, fuse replacement, and bulb changes.

The general manual goes further into carburetor disassembly and float-level inspection, wet-clutch inspection, and transmission disassembly and reassembly. Gear, shift-fork, and shift-drum checks are covered separately, rather than stopping at external adjustment.

Coolant-mixture guidance and reserve-tank level checks address routine cooling-system maintenance. Component-specific cautions explain how silicate-containing coolant can prematurely wear water-pump seals or block radiator passages. Chain-care guidance warns that steam cleaning, high-pressure washing, and certain solvents can damage the final-drive chain’s O-rings.

Technical Specification Highlights

The CBR125R reference data cover lubrication requirements, oil capacities, and drain-plug torque. Cold valve-clearance information and six-speed transmission ratios accompany the fuel-capacity, cooling-system, and tire-pressure specifications. Spark-plug selection, battery specifications, and ignition data are included as well.

The separate data sheet adds carburetor jetting and float-level data, fork-oil quantity and level, and steering-bearing preload. Its electrical entries include stator resistance and pulse-generator and ignition-coil peak-voltage test values.

For bearing service, the general manual’s Tool Compatibility Chart for Standard Bearings identifies wheel-bearing remover kit 07746-0050001 and size-specific remover heads. These are general Honda tool references, not a CBR125R-only tool list.

Parts Illustrations and Wiring Reference

The package also contains 52 separate JPEG parts illustrations. Examples include Crankshaft and Piston (E-15), Clutch (E-9), Front Fork (F-8), and Radiator (F-31). Numbered callouts show assembly relationships; the images are not a complete parts catalog with matching part-number lists.

A separate wiring-diagram photograph, labeled page 20-3, shows the rear/right-hand portion of the circuit drawing, including charging, ignition, cooling-fan, and rear-light connections. It is a partial wiring reference, not a full set of CBR125R wiring diagrams.

Working on motorcycle electrical and mechanical systems involves inherent safety risks. Consult a certified motorcycle technician before engine teardown, brake repair, or complex structural work.
