Yamaha XT250 XT250D OWNER'S MANUAL

Yamaha XT250D dual-sport machines utilize a semi double cradle frame designed to balance rigidity and weight for diverse terrain logic. Engineering leads integrated a constant mesh 5-speed transmission to ensure precise power delivery through a wet multiple-disc clutch and chain final drive framework. This model, the XT250D, along with its XT250DC counterpart, represents a sophisticated synthesis of sporting and touring heritage from a global leader in racing reliability. Propulsion is handled by a 249 cm³ SOHC core featuring a 9.50:1 compression ratio and electric start parameters.

Chassis Architecture & Logic

Advanced link suspension logic defines the rear handling characteristics of the XT250D series, providing 180.0 mm of travel through a coil spring and gas-oil damper assembly. Forward motion is stabilized by a telescopic front fork framework delivering 225.0 mm of travel to manage aggressive surface transitions. Spoke wheel construction remains the standard for durability, utilizing a 21-inch front and 18-inch rear rim configuration to maximize ground clearance.

Operational Framework

Multi-function display logic provides the operator with critical telemetry, including a speedometer, odometer, and dual tripmeters for distance tracking. Safety-critical ignition circuit cut-off parameters integrate the sidestand, clutch, and neutral switches to prevent unauthorized or hazardous engine starts. Halogen bulb lighting provides 60.0 W of high-beam luminosity while maintaining a compact electrical footprint.

Engineering Intelligence & Logic

XT250 Calibration Matrix

Internal engine lubrication logic relies on a wet sump configuration requiring YAMALUBE oils with an API service SG rating or higher for optimal clutch engagement. Friction zone management is critical, as the wet multiple-disc clutch requires precise lever free play of 10.0–15.0 mm to prevent premature slippage or engagement failure. Brake logic utilizes a single disc framework at both terminals, governed by DOT 4 fluid parameters to maintain hydraulic integrity under thermal stress. Periodic maintenance of the air induction and emission control logic ensures compliance with clean air standards without compromising the 249 cm³ displacement efficiency.

FAQ

Workshop compatibility for YAMAHA XT250 XT250D print-outs? 100 pages constitute this comprehensive digital volume, which facilitates high-resolution printing for shop-floor utility. Using the same factory documentation that authorized dealer technicians utilize, owners can perform preventive maintenance or minor repairs using the integrated 10-section layout. The material is specifically formatted to maintain clarity during physical use, ensuring that intricate diagrams of the 249 cm³ engine and semi double cradle frame remain legible in professional environments.

Engine and drivetrain repair coverage for YAMAHA XT250D? 74.0 x 58.0 mm bore and stroke dimensions define the air-cooled 4-stroke SOHC powerplant that requires NGK/DR7EA spark plug parameters. Detailed specifications for the 5-speed constant-mesh transmission include primary reduction ratios of 3.083 and final drive chain ratios of 3.200 for precise logic-framework adjustments. Maintenance protocols ensure long-term durability by specifying 1300–1600 r/min idling speed and exact valve clearance checks while the core is cold.

Relationship between LIT-11626-26-08 and other YAMAHA service volumes? Parameters within the Foreword and Consumer Information sections explicitly link this Owner's Manual to the broader technical suite, including the specialized Service Manual and the "YOU AND YOUR MOTORCYCLE: RIDING TIPS" booklet. While this volume covers essential operation and periodic logic, the professional Service Manual available via yamahapubs.com provides the deeper data required for complex architectural overhauls.
