One of the most revered enduro motorcycles among connoisseurs of two-wheeled "iron horses" is the two-stroke model KTM-250. In 2012, this unit has undergone a number of dramatic transformations. Despite all its "ideality", the designers found what else could be strengthened and improved. Consider the features of this car and its behavior on the track.

Description and equipment

The KTM-250 motorcycle has the characteristics of a variety of sports disciplines, including cross-country, rally, trade and trophy. The equipment is equipped with a suspension with a long stroke, excellent protection of all units and assemblies from mechanical influences and dirt. Riders will be pleased with the smooth operation of the motor, the gaining dynamics and sufficient clearance.

The standard equipment of the motorcycle in question includes basic equipment designed for operation in the city. The machines are provided with light elements, a sound signal and other details that ensure traffic safety in populated areas. The power rating of the updated version is only 17 horsepower. This is due to the carburetor limiters and the reduced size of the resonator outlet. With such characteristics, even a beginner can control the bike.motorcyclist. But the additional equipment of the KTM-250 transforms it dramatically. It includes a second pipe of a sports type, devices for adjusting the carburetor. After installing these “gadgets”, the power of the motorcycle increases to 50 “horses”, while the net weight of the bike is only 103 kilograms.

Design features

Another innovation in the design of this motorcycle is a new frame, thanks to which the weight configuration and handling have changed. The elongated swingarm of the rear suspension assembly felt better, the front 48-mm fork remained practically unchanged. Installed wheels are made of anti-corrosion lightweight alloy.

The rest of the KTM-250 structure remained intact. This primarily concerns the power unit, which, even before restyling, was considered the standard of efficiency and reliability in its class. The only requirement for it is timely and proper maintenance, with regular topping up of special oil for two-stroke engines. The air filter housing has undergone minor changes, which received improved protection against dirt and the ability to pass more air through the filter element in a certain unit of time.

KTM-250: specifications

Below are the specifications of the motorcycle in question, 2010:

• Main gear - chain.
• Engine size - 248, 6 cu. see
• Frame type - half duplex steel modification.
• Height over saddle - 97 cm.
• Wheel base – 1, 48m.
• Clearance - 34.5 cm.
• Weight - 105 kg.
• The power unit is an injection motor.
• Cylinder bore - 76mm with piston stroke 54.8mm.
• Clutch assembly - multi-disc block in an oil bath.
• Gearbox - mechanics for 6 ranges.
• Cooling - liquid type.
• Fuel tank capacity - 9 l.
• Starting - electric starter plus kickstarter.
• Brake system: 4-piston hydraulic disc front, 2-piston rear.
• Suspension (Front/Rear) - Swingarm Single Shock/Inverted Telescopic Fork.
• Wheels (front/rear) - 90/90-21 and 140/80-18.

KTM-250 EXC test drive

Tests of the considered "enduro" made it possible to identify its strengths and weaknesses. To begin with, it should be noted that it is necessary to regularly monitor the oil level in gasoline, otherwise you will have to sort out half of the engine. Other highlights include:

• Special attention must be paid to the serviceability of the engine mute button and the gas cable. The last element has a single structure, which is fraught with its bite in the maximum position. In this case, only a working button will allow you to get out of the situation. Setting up the power unit in terms of jets and needles is available in the manual.
• One of the weaknesses of the engine is the resonator tube. It serves to ensure the nature of traction. In case of its deformation on the elements of the road, there isloss of traction at low rpm.
• The brakes on the KTM-250 motorcycles are beyond praise. They provide reliable stopping of the car. Of the unpleasant moments, air can be trapped in the system when the bike is turned over, however, this happens extremely rarely.
• Discs and basket with adequate control are practical and hardy, despite the fact that you often have to poison the clutch.

Notes

Another problematic place of the motorcycles in question is the electrics. There are practically no complaints about the operation of the main blocks and relays, but the wiring itself in terms of laying and insulation leaves much to be desired, especially given the decent vibration effects. It is worth noting another element - knitting needles. They need regular tightening. Otherwise, you will have to completely change the hub. The bearings of these elements are very durable and effective when used correctly.
