What are the reasons for high fuel consumption in step-through motorcycles?

[NatalieFitz]

High fuel consumption in motorcycles may be caused by excessively high idle speed, or it could be due to low tire pressure leading to excessive friction between the tires and the ground. The following are relevant explanations: Fuel consumption: The fuel consumption of motorcycles is generally within the range specified in the manual. However, improper use, maintenance, or adjustments can often result in a significant increase in fuel consumption. Ignition timing too late or too early: If the ignition timing is too early, the air-fuel mixture burns prematurely, creating resistance to the upward movement of the piston, which consumes part of the effective thermal energy, leading to a decrease in engine power and an increase in fuel consumption. Low fuel octane rating: Using gasoline with an excessively low octane rating can easily lead to increased fuel consumption.
