The chatter of motorcycles appears during braking and consists of a vibration of the rear and front unsprung masses at a frequency in the range of 17–22 Hz depending on the motorcycle. This vibration could be very strong and acceleration of the unsprung masses can reach 5–10 g. The chatter is an auto-excited vibration and this fact explains why it appears suddenly when the mechanism of auto-excitation is generated. This paper presents the chatter phenomenon both from an experimental and a… Expand
The significance of powertrain characteristics on the chatter of racing motorcycles
The chatter of motorcycles is a self-excited vibration that may appear during braking. This vibration can be very strong and the accelerations of both the rear and front unsprung masses can reachExpand
Chatter vibrations of high-performance motorcycles
Motorcycle racing teams occasionally experience speed-limiting vibrations of around 25 Hz frequency in mid-corner. The nature of the vibrations has not been closely defined yet and the mechanics areExpand

Motorcycle Steering Oscillations due to Road Profiling
TLDR
The results show that at various critical cornering conditions, regular road undulations of a particular wavelength can cause severe steering oscillations and explain many of the stability related road accidents that have been reported in the popular literature and are therefore of practical import.
