The amount of fuel consumed by a motorcycle while idling for 30 seconds can vary depending on several factors, including the specific motorcycle model, engine size, fuel efficiency, and idling speed. Additionally, different motorcycles may have different fuel injection systems or carburetors, which can affect fuel consumption.
As a rough estimate, motorcycles typically consume around 0.1 to 0.2 liters (100 to 200 milliliters) of fuel per minute while idling. Considering this, idling for 30 seconds would consume approximately 0.05 to 0.1 liters (50 to 100 milliliters) of fuel.
It's generally recommended to avoid prolonged idling and turn off the engine when the motorcycle is stationary for an extended period, such as during traffic stops or waiting times.
