Mechanical and System Coverage
This factory manual serves as the primary technical reference for the 2007 YZ250F.

Working on high-performance competition machines carries inherent risks, so always verify your equipment and shop safety protocols before tearing down a bike. This publication catalogs original factory repair specifications and maintenance intervals purely as a professional reference standard.
Technical Data and Specifications
Fast access to accurate numbers keeps your service bay moving. The text provides highly specific technical data for the high-performance 249cc engine. This includes strict cylinder head warp limits (0.05 mm) and exact valve clearances (intake: 0.10–0.15 mm). Tightening torque values are clearly documented for all primary fasteners throughout the chassis and powertrain. The primary drive gear, for instance, requires a 75 Nm torque rating. You will also find critical fluid metrics like the 0.99-liter coolant system capacity and ignition data specifying a 0.7–0.8 mm spark plug gap. Spanning the 5XCG, 5XCH, and 5XCK production series, this OEM resource delivers the exact baseline numbers needed to evaluate components before committing to a repair job.
