There are several reasons why most motorcycles use gasoline internal combustion engines. Here are some key factors:
Power-to-Weight Ratio: Gasoline engines have a high power-to-weight ratio, meaning they can generate significant power relative to their weight. This is important for motorcycles, as they need to be lightweight for maneuverability, yet still provide sufficient power for acceleration and speed. Gasoline engines are known for their ability to deliver a good balance of power and weight, making them a popular choice for motorcycles.
Availability and Infrastructure: Gasoline is widely available globally and has an extensive refueling infrastructure in place. This makes it convenient for motorcycle riders to find fuel almost anywhere, whether it's at gas stations or other fueling points. The well-established network of gasoline distribution and refueling stations supports the practicality and usability of motorcycles with gasoline engines.
Performance Characteristics: Gasoline engines can offer a wide range of performance characteristics, allowing manufacturers to design motorcycles for different purposes and riding styles. Gasoline engines can be tuned for high torque at low RPMs or high power at higher RPMs, depending on the intended use of the motorcycle. This versatility in performance characteristics contributes to the popularity of gasoline engines in motorcycles.
Cost and Affordability: Gasoline engines are generally more affordable to manufacture and maintain compared to alternative powertrain technologies, such as electric or hybrid systems. This affordability makes gasoline-powered motorcycles more accessible to a wider range of riders, as they tend to have lower initial purchase costs and maintenance expenses.
Maturity of Technology: Gasoline engine technology has been developed and refined over many years, resulting in a mature and well-understood technology. This leads to reliable performance, ease of maintenance, and a wide range of aftermarket support for gasoline-powered motorcycles. The extensive knowledge and infrastructure surrounding gasoline engines contribute to their dominance in the motorcycle industry.
While alternative powertrain technologies, such as electric motorcycles, are gaining traction and becoming more popular, gasoline engines continue to be the prevailing choice due to their established performance, availability, affordability, and practicality for a majority of riders.
