1986-2007 Honda CR125R Service & Repair Manual (OEM)

• Covers 1986–2007 Honda CR125R motorcycles, detailing engine, chassis, electrical, and fuel system configurations for the 2-stroke 125cc powerplant
• Official Honda Motor Co., Ltd. service publication (August 2002 edition)
• Features 125 exploded-view diagrams, 14 wiring-related illustrations, and 19 comprehensive torque-value specification tables
• Serves as the authoritative factory reference, including specialized tuning charts for 2000–2002 jetting requirements

Maintaining the performance of Honda's liquid-cooled 2-stroke demands precise technical data. This factory documentation breaks down the general maintenance schedules for air filters, spark plugs, and cooling system efficiency. It dives deep into the mechanical specifics, outlining what to look for during engine removal, transmission oil service, and reed valve inspections.

Beyond the powerplant, the material covers chassis specifics. You get clear visual references for front and rear suspension adjustments, hydraulic brake maintenance, and swingarm linkage service. For mechanics wrestling with electrical systems, the manual maps out exact cable and harness routing for the 2000, 2001, and 2002 model years.

Specification and Reference Values

When you are turning wrenches on the CR125R, guesswork is not an option. The technical data delivers precise tightening torques for fasteners across the entire motorcycle—from the engine case to the suspension assemblies. Diagnostic metrics are highly specific. Cylinder head warpage, for instance, has a strict 0.05 mm service limit. The transmission oil capacity calls for exactly 0.57 liters during standard drainage intervals, while magneto pick-up coil resistance for the 2000–2001 models is set at 180–280 ohms.

Need to dial in the carb? The text includes comprehensive workshop documentation covering specialized jetting adjustments based on shifts in altitude and temperature. Keep in mind that servicing high-performance dirt bikes involves mechanical hazards. The service data provided here serves as a reliable reference, but technicians should always verify baseline settings with OEM parameters before tackling complex rebuilds.
