Types of dirt bikes

Two stroke dirt bikes

A two stroke dirt bike consists of a two stroke engine in which the whole combustion cycle is complete with just a single piston stroke. This single piston stroke includes a compression stroke that is followed by an explosion of the compression fuel. The fresh fuel goes to the cylinder when the exhaust is let out during the return stroke. The power in this type of engine is produced in every two stroke and that’s why it is known as two stroke engine. The engine fires and ignites the spark plug for each cycle of the crankshaft. In two-stroke dirt bikes, you have to use only those types of oil that comes pre-mixed with fuel. Venom motorsports sell some of the most affordable 2 stroke mini dirt bike.
