Yamaha SRX 400 - the popular light motorcycle

Yamaha SRX 400 - lightweight motorcycle, designed for dynamic driving in the city, maneuverable and pryemisty - appeared in 1985. His way of life is "enduro" style, which in Spanish means "hardy". The car goes in the given mode indefinitely, to the last drop of gasoline in the tank. Any city traffic jams and jams of the Yamaha SRX 400 motorcycle at all , it starts to spin with a snake and squeezes into the narrowest cracks. Passage is practically unlimited and depends only on the physical training and skill of the rider.

There are a few particularly successful motorcycles in the Japanese motor industry, which is called "from God." SRX 400 is one of them. Goodness in combination with utilitarianism, unpretentiousness and reliability. However, there are disadvantages. One of them is a highly located center of gravity. The rosy driver should be ready for an unstable entry into the turn, and bends are generally contraindicated. Another disadvantage is the frequent oil change, the interval between carrying out this rather troublesome operation is 1000 kilometers if the machine is operated in the city. Well, the last noticeable drawback of the Yamaha SRX 400 (the owners' reviews confirm this) are expensive spare parts. Any breakage will fly in a pretty penny. Although as a consolation - a relatively low cost of consumables.

Engine

The Yamaha SRX 400 motor is structurally simple, even, one might say, unpretentious. XT-400 Artesia got a motorcycle from its predecessor without any performance changes. However, in the new version, the kick starter was abolished, and the engine was equipped with an electric starter. In fact, this addition was not entirely appropriate, since most Yamaha SRX 400 owners are young mobile people who are not interested in starting the engine from the key, but what's done is done. The dynamics of the engine is "dormant", it flexibly increases the thrust, the character is far from explosive, as, for example, in racing "Honda" or "Kawasaki", but at the same Artesia XT is capable and "jerk", if necessary. Affects difficult access to the engine due to the wide volumetric frame of the motorcycle. It is impossible to get to individual sections, and you have to completely remove the power unit if repair is necessary.

Transmission

The Yamaha SRX 400 gearbox is practical and reliable, five speeds are sufficiently close in their gear ratios, and this gives the motorcycle a smooth ride. The nature of the CP is also "enduro", the main advantage is endurance.

Support frame construction

The frame of the motorcycle is strictly functional design, no protective protrusions or hints on the safety of the driver. Tubular spars provide safety of the engine and all accompanying units. When falling, only the headlight and devices will be damaged, which will inevitably break, and even the driver, absolutely not protected by overhangs, which simply do not exist, or with security arcs that have nothing to attach. Such a glaring absence of any means of ensuring security, however, does not bother anyone. The fact is that the Yamaha SRX 400 is not a high-speed motorcycle, in the city it can not be properly accelerated due to the specificity of traffic, and on the highway its speed is also low - a maximum of 115-120 km / h. So the accident with serious consequences of the machine is not threatened.

Pendants and brakes

Suspension brackets SRX 400 are as simple and reliable as the motorcycle itself. The front telescopic fork with oil shock absorbers is quite energy-intensive. Rear suspension - pendular lever with a mono-shock and automatic positional preload. In contrast to the simplicity of the suspension, the Yamaha SRX 400 braking system is a complex of completely inexpensive units and assemblies. The front brake disk with a diameter of 320 mm is taken obviously from the arsenal of racing cars, and a support with four pistons is right for him. The light bike is so strongly upset when braking that the driver has to be careful when pressing the brake pedal. The rear brake is not as steep as the front brake, but also effective.

Running qualities and comfort

Yamaha SRX 400 is a motorcycle of such a class that you can not talk about comfort. The owner is increasingly thinking about how quickly to slip the car plug. And outside the city on the track near the motorcycle are other problems: head-on or side wind and motor vibrations at a speed of about 120 km / h. These factors make us think not about comfort, but about how not to move into the ditch. The short wheelbase also adds challenges. The machine bounces off any roughness of the roadway, and a lateral gust of wind can aggravate the instability.
