What should riders do before starting their motorcycle?

Riders should always check tire pressure and fluid levels before starting their motorcycle as part of a pre-ride inspection. This practice is crucial for ensuring the safety and performance of the motorcycle. Proper tire pressure is essential for optimal handling and stability, while sufficient fluid levels—such as engine oil, coolant, and brake fluid—are vital for the safe operation of the motorcycle. Conducting these checks can help prevent mechanical failures that could lead to accidents or breakdowns while riding.

The other options do not contribute to the motorcycle's safety or readiness for riding. Setting the radio station can distract a rider, adjusting the seat height is only one aspect of personal comfort, and wearing sunglasses should be based on specific environmental conditions rather than a blanket requirement. Hence, performing a thorough inspection focusing on the bike's mechanical condition is the most responsible action before starting a ride.
