Why does your bike bog at low RPMs?

A bike may bog at low RPMs due to several factors, including fuel delivery issues, such as a clogged fuel filter or dirty carburetors/injectors, which restrict proper fuel flow. Additionally, an air intake problem, like a dirty air filter, can prevent the engine from getting the required air-fuel mixture. Ignition system issues, such as worn spark plugs or faulty ignition coils, can also lead to poor performance at low RPMs. Lastly, incorrect tuning or a malfunctioning sensor in modern bikes can contribute to this issue.
