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

A study on the stability of a motorcycle wheel–swingarm suspension with chain transmission
ABSTRACT The present study describes a possible driving mechanism for a self-excited oscillation observed in motorcycle dynamics, often referred to as chatter. This phenomenon, affecting theExpand
Development and validation of an advanced motorcycle riding simulator
This paper illustrates and discusses the main features of the motorcycle riding simulator designed and built at the University of Padua over recent years. The simulator has been developed for aExpand
Investigation of Motorcycle Steering Torque Components
When driving along a circular path, the rider controls a motorcycle mainly by the steering torque. This work addresses an in‐depth analysis of the steady state cornering and in particular theExpand
A virtual motorcycle driver to simulate real manoeuvres from experimental data
The control of single-track vehicles represents a challenging task. The stability is characterized by vibration modes which change with the vehicle speed and acceleration and may possibly becomeExpand

The work illustrates the main features of the motorcycle riding simulator developed at the Dept. of Innovation in Mechanics and Management (DIMEG) of the University of Padova. The simulator consistsExpand
Motorcycle Steering Torque Decomposition
This work addresses the decomposition of the motorcycle steering torque in its main components. Indeed the steering torque applied by the rider on the handlebar is the reaction to many contributesExpand


Motorcycle Steering Oscillations due to Road Profiling
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.
