Besides, do I need to let my motorcycle warm up?
Yes, but it also depends on how old the engine is. If it's a new bike, it will require a few seconds – not minutes – to warm up. This is not only so the oils warm, but so the gaskets and valve seat properly in the new engine. After the first 1000km, you won't need to warm it up for near as long, if at all.
Additionally, does stalling a motorcycle damage it? Nope, nothing that causes a serious or any long term damage, so chill. There is one thing that happens, but in the rarest of rare cases. There is a gear nut that has the primary function of letting the rider shift the gears smoothly. In old motorcycles (sometimes) the gear nut gets jammed due to frequent stalling.
Keeping this in view, is it bad to let motorcycle idle?
Myth busted; idling your motorcycle does not prolong the life of your engine; rather it shortens it. Your motorcycle doesn't run rich the entire winter. It only happens when the gasoline is cold. Once your engine warms up to about 40 degrees Fahrenheit, the car transfers to normal fuel-consumption rates.
What temperature should you not ride a motorcycle?
It is not recommended to ride a motorcycle when the temperature is below freezing (32°F or 0°C). Ice will form at these temperatures and motorcycles are more susceptible to ice since they are smaller vehicles.
