Overview

Yamaha XT 250

The  XT250 may look the same on the outside, but there are a significant number of changes on the inside. A new fuel injection system leads the list. Whether commuting to work or hitting the back country for some exploring, the ultra-reliable XT250 is a fun loving dual sport that is easy to ride. Your adventure starts here.

Power Revised, 249cc, air-cooled, fuel injected, single overhead cam (SOHC), 2-valve, 4-stroke single produces easy to use power for daily commuting or exploring our back country.

Performance 4-stroke engine produces strong, predictable torque across the entire RPM range for great on- and off-road fun. It is very fuel efficient and environmentally friendly too.

ENGINE

• 249cc, air-cooled, fuel injected, single overhead cam (SOHC), 2-valve, 4-stroke single produces easy to use power for daily commuting or exploring the back country. • 4-stroke engine produces strong, predictable torque across the entire RPM range for great on- and off-road fun. It is very fuel efficient and environmentally friendly too. • Convenient, no hassle push-button electric starting. • 2-valve cylinder head. Straight design intake and exhaust tracts provide excellent cylinder filling efficiency for strong low and mid-range power. • Single overhead camshaft is designed to provide good low and mid rpm torque. The conventional rocker arm design means fast, easy valve clearance adjustments. • Automatic cam chain tensioner reduces mechanical engine noise and maintenance. • Ceramic composite cylinder "bore" is a "liner less" design with the ceramic coating sprayed directly on the aluminum block. Benefits include; excellent heat dissipation for consistent power delivery, reduced weight and reduced friction. • 74mm lightweight forged piston provides fast throttle response, excellent durability and less mechanical vibration. • Lightweight ball bearing mounted crankshaft for excellent durability and fast engine response. • Internal engine counter balancer reduces engine vibration to maximize rider comfort. • Multi plate wet type clutch is utilized. Clutch lever pull is light and easy. • Easy access element type oil filter. Oil filter housing is located on the right hand side of the engine for easy servicing. • Maintenance-free TCI (transistor controlled) ignition controls the ignition mapping and produces a hot spark for fast, sure starts. • 16 bit ECU (electronic control unit) controls the fuel injection process. • 33mm, Mikuni throttle body fuel injection system. This system is a return-less FI system with TPS (throttle position sensor). It provides excellent throttle response, great fuel economy, reduced emissions and a choke-free design. • A 10-hole fuel injector is used and provides a 22 degree spray pattern for excellent fuel atomization and strong performance. • 235 watt ACM (alternating current magneto) is used to power the fuel injection system plus the reminder of the electrical components. • 2.8 litre air box is located under the seat and utilizes an easy to access viscous (paper type) air filter. • Wide-ratio, 5-speed transmission and manual clutch are well suited to the engine's power output for easy, relaxed riding. • Steel exhaust system with heat shields on both the header pipe and muffler protect rider and passenger from accidental contact. Exhaust note is quiet and environmentally friendly. A US Forestry Approved spark arrestor protects Mother Nature. • Air Induction System (AIS) injects fresh oxygen into the exhaust to insure complete combustion thereby reducing harmful hydro carbon and carbon monoxide (HC & CO) exhaust emissions.

Chassis/Suspension • Semi-double cradle steel frame and an overall "wet" weight of only 132kg (291 lbs.), make the XT250 one of the lightest, most compact dual purpose machines on the market. • Rugged, box section steel swing arm is fitted with easy-to-use eccentric chain adjusters • 35mm KYB fork with 225mm (8.9") of wheel travel soaks up the rough stuff, both on-road and off. Rubber boots protect fork seals and tubes from dirt and grit damage. • Lightweight aluminum lower triple clamp reduces weight. • Link Monocross rear suspension features a spring preload adjustable shock. The adjustment range is 20mm (0.8"). Rear wheel travel is 180mm (7.1") • Low seat height of 810mm (31.9") creates a low centre of gravity for added manoeuvrability and inspires confidence by allowing most riders to put both feet firmly on the ground. • 285mm (11.2") of Ground Clearance enhances off road use. • 245mm front disc brake with twin piston Nissin caliper provides plenty of stopping power. • 203mm rear disc brake is squeezed by a single piston Nissin caliper with rugged plastic caliper protector and an integrated (or 1 piece) rear master cylinder. • 9.6 litre fuel tank features an in tank electric fuel pump. The low fuel warning light will come on with 2 liters of fuel remaining. • 21" front and 18" rear lightweight DID alloy wheels are extremely durable and reduce unsprung weight for enhanced suspension performance. • Long, YZ-inspired seat creates a balanced riding position and provides roomy comfort for both rider and passenger. The seat features a "pebble style" seat cover. • Frame-mounted passenger footpegs provide two-up riding capability. • Powerful, 60/55-watt, enduro-style, halogen headlight • Small fairing reduces wind buffeting at highway speeds • Compact digital instrumentation includes: speedometer, odometer, dual tripmeters and a clock. Other features include low fuel warning light, engine warning light and self-diagnosis function.

Features • Serrated, folding steel footpegs • Folding gear shift and rear brake lever tip • Steering and helmet locks • Locking fuel cap • Convenient passenger hand rails • Durable "O" ring chain • Dependable, low-maintenance, sealed battery • Flexible turn signals • Easy-to-use, push-to-cancel turn signals • Rubber "boots" on brake and clutch levers help reduce mud and dirt damage.
