It's summer outside, which means it's not only the time for constantly buzzing lawnmowers and mosquitoes; this time of year is also vividly characterized by the appearance of a large amount of two-wheeled transport on the city streets, ranging from the most annoying to the slightly envy-inducing. And as you might guess, we're talking about motorcycles, which are the focus of these lively PC wallpapers. If we exclude the homegrown representatives of non-traditional orientation experimenting with the sound of the engine and the interpretation of traffic rules, then the motorcycle can be rightly called the direct descendant of cavalry, not just riding on horseback. It's the speed and power of the iron horse that provides an incomparable sensation, and such a desktop wallpaper is confirmation of that.
