Ask an Explainer

Q:

Is it possible to use motorcycle engine to power an aircraft?

A:

Yes, it is possible to use a motorcycle engine as part of a prop engine for an airplane; however, lighter engines should be used to minimize weight. A typical motorcycle engine is 55kg, or 121 lbs with a 50cc output.  This means that an aircraft built with this engine would likely fall under the "light sport aircraft" category, since "ultralight aircraft" cannot be more than 254 lbs. Maximum power to weight ratio is essential for a successful airplane with adequate control and safety mechanisms.
