Although naturally aspirating units are slowly becoming a thing of the past, they are still worth being interested in, especially when you buy a used car. Motorcycles of this type are usually less emergency and more vital, so choosing a second-hand vehicle that does not have a recharge system is a move with a lower risk of occurrence of later, costly failures.
The naturally aspirated engines are characterized by high work culture, and in the case of newer units also moderate demand for fuel. They will work above all in urban conditions, where there will not be so much less torque. Naturally-aspirated engines are better able to withstand heavy exploitation on short journeys. Looking at the offer of new cars, you can still find brands that develop engines without recharging system. An example would be Mazda and its Skyactive -G technology based on its effectiveness on a significant increase in the compression ratio.

In drive units equipped with a turbine, the oil that lubricates its bearings also has more difficult operating conditions. The hot exhaust gases that drive the turbocharger rotor to affect the temperature of the lubricating liquid. This increases the number of incineration deposits and other combustion-related by-products that are hazardous to the engine. Drivers should, therefore, take particular care of the quality of oil and intervals of its exchanges, choosing more expensive but better products. Among the top brands, you can distinguish such companies as Motul or Millers.
