The biggest difference is that adventure bikes don’t crash like dirt bikes, and the risk of injury and damage from crashing on an adventure bike is far greater due to reduced personal protective gear and the presence of hard luggage, extra weight, windshields and other things not designed to be crashed on a regular basis.
There are many elements needed to ride well off pavement, so for the first part of this traction management series we’ll focus on the concept of “becoming weightless” when riding on rough surfaces, dirt or gravel.
Becoming weightless improves traction, decreases falls, and reduces the risk of injury by reducing or eliminating the number of times you would otherwise fall. We’ve all seen riders standing on their footpegs, and may emulate this style of riding—often not fully understanding how or why we should stand in the first place. Even worse than standing without purpose is failing to stand at those times when it is most critical— such as in deep sand, mud, ruts, water crossings, etc.; times when untrained riders normally sit. Anyone can stand on a smooth gravel road.
The primary reason for standing on the footpegs while riding off pavement is to become weightless by removing your mass (weight) as the rider from the suspension equation. The concept is fairly simple: By standing on the footpegs, the combined center of mass of rider/motorcycle moves closer to the ground, making the bike less top-heavy and quicker to respond to surface change and directional input.
You may ask, “If I stand up aren’t I raising my center of mass, making the bike more top-heavy?” Without getting too carried away, let’s just say “no”… if done properly you are lowering your combined center of mass even though you have raised your personal mass farther from the ground. If riding technique was just about the rider, you would be correct, but since you and the motorcycle are a unit this line of logic is incomplete.
When you stand up, you move the point at which you, as the rider, support your mass, moving it from the seat to the footpegs. The motorcycle’s center of mass is normally near the carburetor/EFI, so by shifting the rider’s weight (supported mass) onto the footpegs the combined rider/motorcycle mass lowers to a point somewhere between the rider’s feet and the motorcycle’s center of mass.
