• Covers 2008–2013 Yamaha WR250R and WR250X dual-sport motorcycles, documenting engine, chassis, and electrical specifications for the 250cc liquid-cooled 4-stroke models
• Official Yamaha publication P/N LIT-11616-21-66, first edition December 2007
• Serves as the primary reference document for the entire initial production cycle
• Features 12 detailed wiring diagrams and 59 torque tables for engine and chassis fasteners

Core Content Breakdown

The publication spans nine core chapters outlining everything from fuel injection operation to cable routing. You will find detailed cooling system diagrams, general vehicle identification data, and complete electrical system architecture. It also catalogs chassis maintenance requirements covering the suspension, braking, and drive chain systems. Working on modern fuel-injected motorcycles carries inherent risks, so reviewing factory-approved safety precautions before servicing high-pressure fuel lines or electrical components is highly recommended.

Specification and Reference Data

High-depth technical data is critical for accurate bench work. This document provides precise tightening torque values for every major assembly. For instance, the main M10 cylinder head bolts require a 40 Nm torque. The engine specification tables list intake valve clearance at 0.13–0.20 mm, while radiator cap opening pressure is documented strictly at 108.0–137.4 kPa. Having this exact factory data on hand ensures you meet all required mechanical, electrical, and suspension tolerances during a rebuild or routine service.
