These smaller dirt bikes have a number of advantages to the 4 stroke and V6 dirt bikes. The engines of the two stroke dirt bikes have: much stronger acceleration as well as fewer parts to worry about malfunctioning. The 2 stroke dirt bikes themselves are a lot easier to jump in motor cross races, they have a powerband for jumping and the powerband helps the rider do better in trail riding.
The reason the 2 stroke bikes are called ‘2 stroke’ is because of the interesting method their engines function. When this engine’s piston moves down, the mixture of the fuel is pushed under the piston. Then the fuel is compressed into the cylinder. As soon as this fuel mixture is pushed into the cylinder, the exhaust gasses are compressed outwards. The fuel mix is pushed into cylinders through passages or ports in the cylinder walls. As soon as the piston comes up, all of the ports are now covered and the mixture is squeezed. Vacuums are then made in the crank case.
The bikes were made of light weight material and they were easier to handle than the more unwieldy 4 stroke or V6 engine ‘hogs’ in the 1980’s. These 2 stroke dirt bikes could maneuver over any and all country and were popular in dirt racing and other sports loved by young people.
These motor bikes are powerful and they have the ability to move fast. They don’t cost a great deal to manufacture and are light for their size and structure. High revolutions per minute or ‘RPMs’ are a selling point for these motorbikes’ engines. Two stroke bikes were common and seen as being popular dirt bikes until 1985.
These are powerful dirt bikes with speed and power potential. They aren’t expensive to manufacture and they are light weight for their size. The engine features a capacity for high RPM (revolutions per minute). The two stroke dirt bikes were popular as sport bikes until around 1984.
In the 1990’s the four stroke motorbikes were built ‘like tanks’. They were huge and were hard to ride and manage. After the beginning of the 1990’s, the 4 stroke dirt bikes were constructed of much lighter metals and many alloys. Subsequently the 4 stroke bikes became as lightweight and manageable as the 2 stroke dirt bikes. The 4 stroke bikes also didn’t burn oil and fuel at the same, squelching concerns about pollution.
Lobbyists and government environment agencies are having their say in making 2 stroke dirt bikes obsolete. Larger motorcycle companies such as Honda and Mitsubishi are also influencing the public opinion against the 2 stroke dirt bikes. A major negative point remains the pollution issue and the two stroke engine.
Damage to the environment is cited as a major factor in the dirt bikes’ decline. Huge advances in technology could resurrect the 250cc 2 stroke dirt bikes. Methods and means already are in existence to manufacture two stroke bike engines that are even MORE environmentally friendly as those of a four stroke motorbike. Perhaps one day soon the 2 stroke dirt bikes will once again be a motorbike force to be reckoned with! This dirt bike has it all for need for speed riders. Its also a huge benefit to have such high performance with little malfunctioning.
