The ABC's of Traction - Cornering (Page 5 of 7)

As we look through the curve, we also lean our motorcycle to begin negotiating the turn. Pressing on the inside handgrip causes our bike to lean in the direction of the curve. "Press right - go right" and "Press left - go left" are the axioms of counter steering. (See Counter Steering) To make our motorcycle lean more we simply need to press more on the inside handgrip. The more firmly we press, the more our bike leans into the turn.

Finally we gently roll on the throttle as we smoothly glide through the curve. This gradual acceleration helps to stabilize our motorcycle's suspension ensuring our traction balance between front and rear tires remains constant. The action of rolling off the throttle has the same effect as rear wheel braking so we are now using some of our rear wheel's traction for braking force as well as cornering force.

As we know, braking causes a weight transfer forward, reducing the weight- and hence the traction - on the rear wheel at the same time we are trying to use traction for both cornering and braking. A sudden roll on of the throttle causes a similar effect on the front wheel, lightening it and reducing its traction, at the same time we are increasing the cornering force needed to accommodate the increased lean caused by the increase in speed.

Path of Travel

The path we choose to ride through the curve impacts the amount of traction we need for cornering. By making our path of travel as wide as possible, we reduce the amount of traction we need to hold us in the curve. For a constant radius curve, one that is the same radius throughout, an outside - inside - outside path works best and is the preferred line through the curve.
