yes but unlike two strokes they do not jump when coming off and on the powerband
All fuel powered engines have a power band. The power band simply refers to the rpm range that the engine makes the most power. Four strokes usually have a wider power band than two strokes.
Motorcycles typically have internal combustion engines, which can be classified into two main types: two-stroke and four-stroke engines. Two-stroke engines are lighter and simpler but generally less fuel-efficient and produce more emissions. Four-stroke engines are more common in modern motorcycles, offering better fuel efficiency, lower emissions, and greater durability. Additionally, some motorcycles use electric motors, particularly in electric models, providing an alternative to traditional combustion engines.

Two stroke engines will create a lot of visible smoke pollution and also more noise than four stroke engines. For these reason, many countries have required that all new motorcycles should be four-stroke.
two stroke engines have a power stroke every second revolution of the crank shaft. four strokes have a power stroke every fourth revolution of the crank shaft. that is why a 125cc two stroke has about the same power as a 250cc four stroke.
The Suzuki DR series consists primarily of four-stroke motorcycles. Models like the DR-Z400 and DR650 are well-known examples that feature four-stroke engines, which are favored for their reliability and fuel efficiency. In contrast, Suzuki's two-stroke models, such as the RM series, are designed for different riding applications.
The four strokes of a four-stroke engine are the intake, compression, power, and exhaust strokes. During the intake stroke, the engine draws in air and fuel. The compression stroke then compresses this mixture, followed by the power stroke, where the spark plug ignites the mixture, generating power. Finally, in the exhaust stroke, the engine expels the burnt gases from the combustion process.
Four stroke engines are quieter than two strokes, but have less power.
compare the two stroke and four stroke engine in power output and thermal efficiency?
The four-stroke engine produces 1 power stroke for every 720 degrees of crankshaft rotation.
The four strokes of an internal combustion engine are intake, compression, power, and exhaust. During the intake stroke, air and fuel are drawn into the combustion chamber. In the compression stroke, the mixture is compressed. The power stroke is when the compressed mixture is ignited to create power, while the exhaust stroke expels the burned gases from the chamber.
