Why should you park your motorcycle in 1st gear?

Parking your motorcycle in 1st gear is primarily a safety measure to prevent it from rolling. When the gear is engaged, it helps to lock the rear wheel in place, which is particularly important on inclines or uneven surfaces. This action minimizes the risk of the motorcycle moving unintentionally, which can lead to accidents or damage to the motorcycle.

While engaging 1st gear might indirectly contribute to theft prevention by adding an extra step for a thief to take, the main intent behind this practice is the stability it provides. Additionally, starting a motorcycle in gear is not typically easier—most bikes require the clutch to be pulled in if it's in gear when starting, making it potentially more complicated. Thus, the focus on preventing rolling makes this answer the most accurate regarding safe parking practices.
