Motorcycle Turning

"Question: If you are on a motorcycle going down the highway, and you press on the inside of the left handle grip, why do the wheels turn to the right, but you turn to the left?" Answer here


Speed 101: Motorcycle Racing as Real-World Physics Lab

Sarah Carter Shares Her Thoughts

Despite what some people may think, motorcycle roadracing is not only a highly strenuous sport, but there is MUCH more involved than just twisting the throttle and turning the handlebars.

This page contains a limited bibliography of technical papers related to the modling [sic] and simulation of motorcycle dynamics. Much of the work has been done in the UK, where Prof. Robin Sharp works with the same symbolic code generator (VehicleSim Lisp, formally known as AutoSim) used by Mechanical Simulation.

Stable bicycle without gyroscopic forces or trail

To find the essence of bicycle self balance we looked at simpler and simpler dynamical models until we found a minimal two-mass-skate (TMS) bicycle that theory told us should be self-stable. This bicycle has no gyroscopic effect and no trail. We built a bicycle (of sorts) based on the theory to prove the point.

This bicycle proves that self-stability cannot be explained in any simple words. Bicycles are not stable because of gyros, because you can make a self stable bicycle without gyros. We did that. And they are not stable because of trail, you can take that away too. And we did that. More positively, we have shown that the distribution of mass, especially the location of the center of mass of the front assembly, has as strong an influence on bicycle stability as do gyros and trail.

Why can a bicycle balance itself? One necessary condition for bicycle self stability is (once we define the words carefully) that such a bicycle turns into a fall.

A Point of Physics (PDF) discusses gyroscopic forces, angular momentum, and includes a few interesting sketches. Short and to the point, discusses steering by moving the rider's body... but... according to Keith Code's No B.S. test bike it's not the body lean. Very interesting... (Popular Mechanics)
