Yamaha XT250 Features and Benefits

?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.

?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 design features the cam chain on the right side. Straight design intake and exhaust tracts provide excellent cylinder filling efficiency for strong low and mid-range power.

?For 2013, the cylinder head features an intake port shape change and new engine temperature sensor to accommodate the new fuel injection system.

?Single overhead camshaft is designed to provide good low and mid rpm torque. The conventional rocker arm design means fast, easy valve clearance adjustments.

?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 (no heavy iron liner) and reduced friction.

?New 74mm lightweight forged piston features a reduced "skirt" length (aka piston side wall) and new underside ribs for additional strength. The piston pin diameter has been increased by 1mm to 17mm. The lightweight piston design provides fast throttle response, excellent durability and less mechanical vibration.

?Lightweight ball bearing mounted crankshaft utilizes a revised connecting rod with larger big end bearing (32mm) for excellent durability.

?Internal engine counter balancer reduces engine vibration to maximize rider comfort.

?New high capacity engine oil pump

?Multi plate wet type clutch is utilized. Clutch lever pull is light and easy to use.

?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.

?All new, 33mm, Mikuni throttle body fuel injection system is used. This system is a return-less FI system with TPS (throttle position sensor). This system 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.

?New higher output 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.), makes 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 seals and tubes from dirt and grit damage.

?Lightweight aluminium 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.

?Revised 9.6 litre fuel tank features an in tank electric fuel pump. The low fuel warning light will come on with 2 litres of fuel remaining.

?21" front and 18" rear lightweight DID alloy wheels are extremely durable and reduce unsprung weight for enhanced suspension performance.
