Not exactly an enduro model and not a either, the WR250R is for riders who off-road more than on.

2013 Yamaha WR250R and Benefits

-Potent, liquid-cooled, DOHC, 4-valve, 4-… with super light intake valves and electronic injection.

-Super convenient starting means fast, starts.

-Hassle free decompression system ensures starting and reduces battery requirements.

-Lightweight magnesium head cover helps weight.

-Double overhead 4-valve combustion chamber a compact pent-roof design for breathing efficiency.

-Downdraft straight design intake provides the most efficient flow for maximum engine

-Intake side, lightweight valves and load-reduced springs weight by more than 40% (Vs valves). Titanium valves reciprocating mass for faster-revving, reduced frictional losses for power delivery across the rev Intake valves are 30mm in while the steel exhaust are 24.5mm in diameter.

-Steep angles, 11.5 degrees on the side and 12.5 degrees on the produce a more compact chamber.

-Dual electrode NGK spark plug is located in the of the combustion chamber for fast, combustion and great throttle

-Ceramic composite plated provides excellent heat for consistent power delivery, friction for increased power and weight since there is no iron sleeve or liner.

cylinder design features that allow the air trapped the piston to enter a side (or cutaway) to reduce horsepower-robbing losses.

-Special design also utilize cutaways to pumping losses. The crankcase match the cutaways in the cylinder to ‘pumping losses.

-The feature a tri-axis design for the main and drive axles. tri-axis design keeps the more compact while centralizing mass for better All of the shafts are positioned low in the cases to a low centre of gravity for great and maneuverability.

-Lightweight, high strength, forged aluminum piston great durability and its lightweight means fast engine and reduced mechanical vibration.

roller bearing style with optimized mass excellent response and strong

-Engine counter balancer vibration for improved rider and reduced rider fatigue. bike can cruise at highway comfortably.

-Special design performance camshafts (intake provide outstanding class power. The cams feature a WPC Process Craft) treatment increases surface hardness for durability and reduced sliding

-Wet sump lubrication is used. This system weight and the number of moving versus a dry sump system.

oil cooler utilizes a pinpoint that directs oil to the desired of the cylinder and underside of the piston, reduces piston, cylinder and rod for great durability.

-Oil in engine has been optimized to weight and oil drag related losses.

-Easy access oil filter is used.

-Compact hydraulic automatic cam chain reduces maintenance and mechanical noise.

-38mm, Mikuni throttle body fuel system is used. This is a return-less FI system with TPS position sensor). This provides excellent throttle great fuel economy, emissions and a choke-free design.

response and acceleration are excellent.

nozzle type 2 hole are used and provides a dual pattern for excellent fuel and best in class performance.

to service 4.1 liter air box with a control valve provides of the art intake and emission control. The air filter is a washable design.

-Maintenance-free transistor-controlled digital (TCI) ensures fast and great performance at all rpms.

16 bit ECU features 3D ignition mapping to the engine power characteristics. The ECU optimal timing at all rpms for engine response.

-Lightweight ignition coil is integrated the plug cap to reduce weight and

-Wide ratio 6-speed features gear ratios for on and off road riding. This adopts a shower type system for great reliability.

clutch matches engine and offers a light, progressive feel with less effort for smoother shifting.

lightweight aluminum outer cover allows fast, access to the clutch.

-Single, rad is used. The exhaust air (after it has through the rad) is directed from the rider for excellent comfort. An electric cooling fan consistent engine temperatures in stop and go traffic.

The single rad is on the left side of the fuel

-Lightweight, compact rare-earth-type ACM current magneto — 14V output ) is used.

-Upswept system features a stainless header pipe and a compact expansion type muffler a honeycomb catalyzer to reduce emissions. This system engine power and allows replacement of the oil filter. It features a screen-type spark arrestor.

shields protect rider and

-The exhaust system features Yamaha’s EXUP (Exhaust Ultimate Power The single butterfly valve the blow back phenomenon by valve overlap. The EXUP eliminates flat spots in the band and reduces emissions

-Solenoid activated Air Induction (AIS) reduces harmful emissions


-Lightweight, aluminum semi-double-cradle frame a variety of components. The main is cast aluminum, while aluminum is used under the frame below the steering area and separate detachable tubes are thin walled tensile steel. Yamaha has the semi double cradle to allow for controlled flex to suspension action.

This design provides a low centre of for a light feel and razor handling.

-Detachable high steel rear sub frame is of round steel pipe. The design provides easy suspension access and reduces in the event of loop out.
