Yamaha SRX 400 - a lightweight motorcycle designed for dynamic city driving, agile and torquey - appeared in 1985. His lifestyle is "enduro" style, which means "hardy" in Spanish. The car goes in a given mode for an infinitely long time, until the last drop of gasoline in the tank. Any city traffic jams and traffic jams are nothing for the Yamaha SRX 400 motorcycle, it starts spinning like a snake and squeezes into the narrowest cracks. Cross-country ability is practically unlimited and depends only on the physical training and skill of the motorcyclist.

There are some very successful motorcycles in the Japanese motorcycle industry, which is called "from God". SRX 400 is one of them. Quality factor combined with utility, unpretentiousness and reliability. However, there are also disadvantages. One of them is a high center of gravity. A tall driver must be prepared for unstable corner entry, and cornering is generally contraindicated. Another disadvantage is the frequent oil change, the interval between this rather troublesome operation is 1000 kilometers if the car is operated in the city. Well, the last notableThe disadvantage of the Yamaha SRX 400 (owner reviews confirm this) is expensive spare parts. Any damage will cost a pretty penny. Although as a consolation - the relatively low cost of consumables.

Engine

The Yamaha SRX 400 motor is structurally simple, one might even say unassuming. The XT-400 Artesia was inherited 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 are kind of "dormant", it elastically increases traction, the character is far from explosive, like, for example, a racing Honda or Kawasaki, but at the same time, Artesia XT is capable of "jerk" if necessary. Disappointing difficult access to the engine due to the wide volume frame of the motorcycle. It is impossible to get close to individual areas, and you have to completely remove the power unit if repairs are needed.

Transmission

The Yamaha SRX 400's transmission is practical and reliable, with five speeds close enough in their gear ratios to give the bike a smooth ride. The character of the CP is also "enduro", the main advantage is endurance.

Structure frame

Motorcycle frame of strictly functional design,no protective protrusions or hints of driver safety. Tubular spars ensure the safety of the engine and all related units. In the event of a fall, only the headlight and devices will suffer, which will inevitably break, and even the driver, who is absolutely not protected either by overhangs, which simply do not exist, or by safety arcs, which have nothing to attach to. 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 cannot accelerate properly due to the specifics of street traffic, and on the highway its speed is also low - a maximum of 115-120 km / h. So the car is not in danger of an accident with serious consequences.

Suspensions and brakes

SRX 400 suspension is as simple and reliable as the bike itself. The front telescopic fork with oil shock absorbers is quite energy intensive. The rear suspension is a pendulum linkage with a monoshock absorber and automatic positional preload. In contrast to the simplicity of the suspension, the Yamaha SRX 400 brake system is a complex of not cheap components and assemblies. The front brake disc with a diameter of 320 mm is clearly taken from the arsenal of racing cars, and a four-piston caliper to match it. A light motorcycle sags so sharply when braking that the rider has to be careful when depressing the brake pedal. The rear brake is not as "cool" as the front, but still effective.

Ride and comfort

Yamaha SRX 400 is a motorcycle of such a class that there is no need to talk about comfort. The owner is thinking more and more about how to quickly get through the traffic jam. And outside the city on the highway, the motorcycle has other problems: head or side wind and engine vibrations at a speed of about 120 km / h. These factors make you think not about comfort, but about how not to go into a ditch. The short wheelbase also adds to the problem. The car bounces off any unevenness in the roadway, and a side gust of wind can exacerbate the instability.
