1. The first motorcycle ran on steam! In 1867, an American inventor named Sylvester Howard Roper attached a small twin-cylinder steam engine to a wooden bicycle frame, creating the very first steam-driven motorcycle.

2. They balance using physics spinning magic. Ever wonder why motorcycles stay upright when moving? It’s partly thanks to the gyroscopic effect! Spinning wheels act like spinning tops, naturally resisting falling over as long as the bike is rolling forward.

3. The world's fastest motorcycle went over 370 mph. In 2010, rider Rocky Robinson set the world land speed record in a specially designed streamliner motorcycle named the Ack Attack, reaching a blistering 376.36 mph (605.69 km/h) across a flat salt desert!

4. They use your hands and feet to drive. Driving a manual motorcycle is a full-body workout! You control the throttle and front brake with your hands, while your left foot clicks through gears and your right foot operates the rear brake.

5. A motorcycle was built out of wood. In 1885, German inventors Gottlieb Daimler and Wilhelm Maybach built the Reitwagen ("riding car"), which is considered the first gasoline-powered motorcycle—and its entire frame and wheels were made of carved wood!

6. The longest motorcycle ever built fits 25 people. In 2015, a plumber named Bharat Sinh Parmar constructed a functional motorcycle in India that measured a massive 86 feet and 3 inches (26.29 meters) long!

7. Riding gear acts like armor. Motorcycle helmets, leather jackets, and gloves aren't just for style—they are high-tech safety gear! Modern race suits even have miniature built-in airbags that inflate in a fraction of a second if the sensors detect a fall.
