What is one of the four necessary preparations before riding a motorcycle?

A crucial preparation before riding a motorcycle is ensuring that the motorcycle is a good fit for the rider. This means that the rider should be able to reach the controls comfortably, have proper foot placement on the ground while seated, and maintain overall control of the bike. A good fit enhances confidence and agility, allowing the rider to handle the motorcycle effectively and safely. This consideration significantly impacts the rider's ability to maneuver and react to various situations on the road, contributing to overall safety.

In contrast to this, simply decorating the motorcycle does not affect its safety or the rider's ability to control it. Having the latest riding gear, while important for protection, is not sufficient if the motorcycle itself is ill-suited to the rider. Similarly, having a ride plan is beneficial for organizing a journey, but it cannot substitute for the foundational necessity of the motorcycle being a proper fit for the rider.
