[QUOTE="BillyWho, post: 123863, member: 22397"] RMG explained it very well . The only difference of opinion I have is I think it is inertia of the combined weight of the rider/bike and the CG, not so much centrifugal force. The way I understand centrifugal is it has an "attached" center point of rotation that is fixed. Inertia of weight has no "guide" to where it goes other than it wants to keep going in the same direction it is already traveling. When you are coming into a corner all the "mass" is headed in one direction, then you steer/lean the bike to turn , and what makes you turn is the bite the tires have on the ground verses or overcoming the inertia of the weight wanting to continue straight. RMG explained perfectly about how shifting the CG to as low and in line with the center line of the contact point of the tires as possible is key, and the only thing to add to help understand better is when you have all your weight on the seat and the bike is leaned over, the angle from your butt (your CG) to the centerline of the tires, let's say 15 degrees, is the angle that the weight of your body is pushing on the tires, which means your helping keep an outward (straight) force on the inertia of you and the bike. When you weight the outside peg, you are putting all the force directly straight down on the center of contact ( at least as close as your going to get) of the tires which gives you as much "down force" as possible to get more traction to over come the "mass" wanting to continue straight. Kind of the same theory as Indy cars. They try and create as much straight down force as possible to keep the tires glued to the track, other wise as you know when they loose traction going into a corner at 200mph that incredible amount of inertia continues straight till they hit the wall:( ! Everything evolves around gaining traction with the contact of ground/tires to get the bike to go where YOU want it to go. Just my 2 cents:) If there is a berm or rut, it's not near as important , but it still keeps the bike more stable and controllable. stormer, the reason it feels more controllable is the increased traction your getting gives you more "control" on what happens with the rear wheel , verses a little "pebble" starting the loss of traction untill your face down in the dirt.
