The machine that allows us to move around without hindrance, the one that can serve us during all our movements in all types of terrain is none other than the motorcycle. engine. To this end, this element is one of the centerpieces of your two-wheeled vehicle. It comes in two operating modes, 2-stroke and 4-stroke. For an average person, it can seem difficult to know all the information and retain all of it. However, it deserves to detail a few in this article. This will help you to better deal with a case of malfunction, internal failure or just to better maintain your motorcycle.
The choice of engine should be based on a few configurations, the motorcycle model and the number of cylinder which can range from a single cylinder to 6 cylinders. In connection with this, it is also necessary to take into consideration the type of architecture that is to say, the positioning of an engine varies from one motorcycle to another. Before buying, you should know that each type of engine has its own configuration and performance.
It is logical that we are looking for a powerful or less powerful engine, the first thing that interests us is the good quality / price ratio. This does not only concern motorcycles but can affect different product categories. In order to better you help in choosing the type of engine to install on your motorcycle, we will give you the different characteristics of it and the different types.
The different types of motorcycle engine
The single cylinder engine
This type of engine is a fairly old design, it is mounted in a vertical position turning slightly towards the road. The crankshaft thereof is generally transverse. For the cooling system, you have two possible options either it is done by air or with a liquid. It is ideal for off-road, sporty type motorcycles or for novice motorcycles. Technology has evolved and now we can see them in displacement from 125 to 690 cm3. We can sometimes even find it in the form of a 4 stroke.
The advantages with this type of engine are that it is easy to maintain, quite light thanks to its components and the type of material with which it was made. Add to all this the cost which is really cheaper compared to other type of engine. However, this one exhibits vibrations, has less mileage and is less powerful. Which means it's not made for competition.

The 2-cylinder engine in transverse position
This type of motor is V-shaped. It is also a fairly old design. We easily recognize this type of engine by its operating system, two connecting rods will turn on a single crank. On the other hand, on a false V-shaped engine, the cranks are distinctly separated. The 2-cylinder V-engine is one of the most versatile. It is made for almost all roadster type motorcycles, cruisers, sportsmen or super sportsmen etc. Apart from that, the technical installation is also versatile, the cooling can be air or liquid. The camshaft can be positioned up or down, the number of valves can vary from 2 to 4.
The main advantages of the latter are found in the torque mode which is high even in the case of a slight displacement. The overall width is quite low, as for the overall length, it is short. Notwithstanding, you should know that this engine is subject to strong vibrations, it requires much more part than a single cylinder model and it emits a fairly large thermal load.

4 cylinder engine in transverse position
Once again this type of engine installation is rare these days. However, that does not mean that it is non-existent. The cylinder is also positioned on it at an angle of 90 ° or 65 ° depending on the motorcycle model. The cooling system is essentially liquid. We can see two camshafts which is in each row of cylinder. It should be noted that there can be up to 4 valves per cylinder.
One can cite as an advantage the small overall width, the presence of bearings which optimizes the ease of driving in when turning. However, the parts of it are quite expensive and the guidance system is relatively complex at the level of the manifold.

The 2 or 4 cylinder engine in longitudinal position
We can say that this kind of engine model is rare nowadays. For those which are 2 cylinders having an air or oil cooling system for certain models of motorcycles. On the other hand for the models with 4 cylinders, the cooling system is done only by liquid. The arrangement of the connecting rods are roughly the same as that of a single cylinder. When the cylinders are positioned at an angle of 90 °. This means that they will be directly fixed in a crank.
The advantage with this type of engine is that its center of gravity is low, it ensures good overall balance and does not require deflection. However, the construction of this kind of model is a bit too high. The overall length is also too great, especially for 4-stroke models.

The 2- to 6-cylinder engine in parallel position
This type of engine is a more common version. The positioning of the cylinders is done linearly. That is, they are arranged in parallel ways. The cooling is done by liquid and it has two overhead camshafts. This kind of engine is made for all types of motorcycles that exist, whether sports, roadsters, all-terrain or even motorcycles for novices. The advantage with the latter is that its mass is very stable which reduces vibrations. Other than that, almost all of its parts are stationary. However, there is too much overall width for models with more than 4 cylinders.

The characteristics of a good motorcycle engine
The power
The choice of a motorcycle must first relate to the power of its engine. For this purpose, the power which is measured in KW translates into the minimum number of times by which it reaches will reach its peak. generally we compare the power with the speed at which a motorcycle rolls or in hp. This is not wrong, however, other configurations must be taken into account. The power of your engine can be increased by trying some modifications to the displacement level or by improving the injection system. Another option is to solidify the engine so that it can gain tone.
Le couple
Before starting it is useful to specify that the torque is measured either in m.kg or in Nm. In terms of two-wheeled vehicle this term means the capacity of your engine to climb slopes and accelerate. All this with a load above. Loads can be human or any type of cargo possible. Technically, this is how it works, the piston will exert a force on the crankshaft which will then actuate the rear wheels of your motorcycle. For motorcycle fanatics, they are looking for the maximum power for the torque. As a result, they want to go up to high revs as quickly as possible and they do not take into account the correct configurations of a linear torque. You have to choose an engine that provides maximum comfort and maximum fluidity.
Cubic capacity
The displacement is none other than the size of the engine of your motorcycle. You have probably already noticed that people speak in cm3 or in cc. This allows you to reference the volume of your engine. The size can range from 50 to over 1000 cc. We will not go into details because you could risk losing the thread quickly. What should be noted before out is the type of displacement you have. Is it a single cylinder or a twin.
Motorcycle engine maintenance
To maintain your motorcycle and to ensure a good longevity, it is necessary to replace the coolant on a regular basis. Apart from that, do not hesitate to change the various filters which are worn or defective, to carry out a regular drain. To finish, it is necessary to check in a punctual manner the presence of any clearances at the level of the valves.
