Yamaha SRX 400 is a lightweight motorcycle designed fordynamic driving in the city, maneuverable and lively - 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 Yamaha SRX 400 motorcycle at all, he begins 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 motorcyclist.
There are a few particularly successful in the Japanese motor industrymotorcycles, which is called "from God." SRX 400 is one of them. Goodness in combination with utilitarianism, unpretentiousness and reliability. However, there are drawbacks. 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 conducting 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 (reviews of the owners 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,it can be said, unpretentious. XT-400 Artesia got a motorcycle from its predecessor without any changes in characteristics. However, in the new version, the kick starter was eliminated, 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 traction, 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
Коробка передач модели Yamaha SRX 400 практичная 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,no protective protrusions or hints on the safety of the driver. Tubular spars ensure the safety of the engine and all associated units. When falling, only the headlight and devices will be damaged, which will inevitably crash, 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 blatant lack 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.
Suspension and brakes
SRX 400 pendants are as simple and reliable asand the bike itself. Front telescopic fork with oil shock absorbers is quite energy-intensive. Rear suspension - swing arm with mono-shock absorber and automatic positional preload. In contrast to the simplicity of the suspensions, the Yamaha SRX 400 brake system is a complex of completely cheap assemblies and units. The front brake disc with a diameter of 320 mm is clearly taken from the arsenal of racing cars, and a four-piston caliper is suitable for him. A lightweight motorcycle is so sharply upset when braking that the driver has to be careful when pressing the brake pedal. The rear brake is not as “cool” as the front brake, but also effective.
Driving performance and comfort
Yamaha SRX 400 - a motorcycle of this class, what aboutcomfort to say no. The owner is increasingly thinking about how to quickly slip through the traffic jam. And outside the city on the highway, the motorcycle has other problems: headwind or side wind and motor vibrations at a speed of about 120 km / hour. These factors make you think not of comfort, but of how not to move into a ditch. The short wheelbase also adds problems. The car bounces off any unevenness of the roadway, and a side gust of wind can aggravate instability.
