How do you know where to shift your gear while riding?

To know when to shift gears while riding, pay attention to the engine's RPM (revolutions per minute) and the bike's speed. Shift up when the engine reaches a higher RPM, typically around 2,500 to 3,000 RPM for most motorcycles, to maintain optimal power without straining the engine. Conversely, shift down when the RPM drops too low, usually around 1,500 RPM, to avoid stalling. Additionally, listen to the engine's sound and feel the bike's response to help determine the right moments to shift.
