2007 Suzuki RM125 Service Manual OEM (P/N 99011-36F56-03A)

Whether you are rebuilding the top end or dialing in the chassis for race day, this official factory documentation delivers the precise Mikuni TMX38SS factory jetting parameters needed to properly compensate for altitude and temperature changes. Designed strictly for the 2007 Suzuki RM125 2-stroke competition dirt bike, it provides the structural blueprints required for professional-level service.

Core Manual Details:

• Official Suzuki Publication: P/N 99011-36F56-03A (First edition, 2007)
• Comprehensive Coverage: 252 pages detailing the 125cc powertrain, 6-speed transmission, and chassis geometry.
• Format: High-resolution digital PDF.
• Targeted component focus: Mikuni TMX38SS carburetor, exhaust valve governor, throttle position sensor, magneto rotor, water pump, and reed valve.
• Crucial workshop procedures: Crankcase separation, front fork tuning, rear shock absorber oil replacement, kick starter inspection, and swingarm linkage maintenance.

Daily Workshop Value & Maintenance

This manual is built for the reality of high-stress race conditions. It outlines rigorous break-in procedures for new parts and specifies highly detailed service intervals for the 2-stroke exhaust valve, piston, and cylinder bore. You will also find comprehensive troubleshooting schematics that map out the ignition system, fuel delivery, and clutch assembly.

Instead of paying a dealership for specialized labor, this documentation walks you through high-level repair operations. It includes detailed step-by-step instructions for overhauling the front fork damper rod assemblies, rebuilding the nitrogen-charged rear shock absorber, splitting the crankcase for bottom-end rebuilds, and performing complete engine top-end jobs. To further support these intricate tasks, the manual incorporates the official wiring diagram, periodic maintenance charts, an engine coolant density-freezing point curve, suspension setting data charts, carburetor exploded views, and highly detailed wire, cable, and hose routing views.

Engine and Chassis Specifications

The documentation delivers precise technical data required for suspension tuning, including exact compression and rebound damping settings.

When executing a repair on the 2007 RM125, technicians must be aware that the water pump impeller features left-hand threads; applying standard loosening torque will quickly snap the shaft. Additionally, during front fork teardowns, pushing the inner rod thread into the damper rod after removing the lock-nut will immediately destroy the delicate inner rod oil seal.

Essential workshop data includes:

• Assembly Torque Values: Clear specs, such as the 100 Nm rear axle nut and the 17.5 Nm spark plug requirement.
• Fluid Capacities: Detailed mixing ratios for 50:50 antifreeze/water coolant mixtures.
• Suspension Tuning: Variable fork oil quantities ranging between 314–408 ml, depending on your specific spring rate setup.

Working on competition-grade motorcycles requires absolute precision. The specifications within this OEM documentation are designed to guide qualified technicians and experienced builders in executing safe, reliable maintenance. Always ensure you have the correct tools and foundational mechanical knowledge before tearing into the engine block or altering factory chassis geometry. Handling toxic materials like DOT 4 brake fluid or servicing the 139.5 psi nitrogen-charged shock demands a properly ventilated, professional environment to prevent severe injury.
