lugging the engine

[KrazyBones]

Hey guys,

My friend was riding my R1 and told me that my bike vibrates and makes a weird noise when lugging the engine (riding too low in the rpm)

I tried gis R6 and the vibration and noise is not as bad. The bike seems fine if i ride it normally. Is there anything i should be worried about?

Don't lug your motor.

Lugging the motor is very bad (especially new bikes, first 1000 kilometres).
