From: Doug Gwyn (VLD/VMB) <gwyn@brl-vld> Please do not attempt to steer a motorcycle at high speed by turning the handlebars in either direction! Instead, lean your weight in the direction you want to turn (knee pressure on the fuel tank).

From: Charles M. Spitzer <Spitzer%pco @ CISL-SERVICE-MULTICS> This is not the appropriate forum for this, but you have presented a popular misconception. The easiest, fastest and safest way to turn a motorcycle at speed is to turn the handlebars. It is called counter-steering, and is taught as a high-speed emergency maneuver to aviod obstacles in your path. On the subject of why a cycle turns the opposite way from a turn of the handlebars, there was a long write-up on this subject in the magazine Road Rider about 2 years ago by some physics professor. The conclusion he came up with was: A front motorcycle wheel is not flat on the bottom. Therefore when the handlebars are turned, it presents the side of the wheel opposite to the turn to the pavement. This causes the front wheel to slightly tilt. The side of the wheel forms a conic shaped form, with the apex of the cone at the center of the circle formed by the rolling cone. This causes the cycle to turn on the perimeter of the circle Charlie Spitzer Spitzer%pco-multics@cisl
