Abstract
This paper presents the results of a program investigating the potential of unconventional motorcycle configurations for improved accident avoidance performance. Stability and obstacle avoidance characteristics were investigated analytically using mathematical models of both the uncontrolled and rider-controlled motorcycle. The results indicate that a low center of gravity, long wheelbase configuration has advantages in the moderate-to-high speed regime in terms of the margin of safety in performing an obstacle avoidance manoeuvre, and rider skill level required in braking.
