When riding in a group formation on motorcycles, it is generally recommended to maintain a safe distance between bikes for safety reasons. The typical formation used is called the staggered formation, where riders are positioned in alternating positions, one to the left and the next to the right of the center line.
In this formation, a common guideline is to maintain a two-second following distance behind the bike in front of you. This means that you should choose a fixed point such as a road sign or a landmark, and when the bike in front passes that point, you should be able to count "one thousand one, one thousand two" before you reach the same point. This distance allows for an adequate reaction time and provides a buffer in case the rider in front needs to brake suddenly or take evasive action.
It's crucial to use your judgment and adjust your following distance accordingly to maintain a safe and comfortable riding experience.
Remember to always prioritize safety and adhere to local traffic laws and regulations when riding in a group formation or any other riding situation.
