from the educator,
The following is an excerp from an
article by Freddie Spencer, who has a performance riding school, and was a
championship racer, taken from Honda RedRider Magazine:
The
year I won both the 250cc and 500cc championships, I had to find ways to
conserve my energy and strength when running two 50-minute GP's back-to-back,
and in doing so discovered that there were multiple ways to affect how the
motorcycle steered and transitioned. It was during that time that I began to
exploit the same techniques that I now introduce on the first day of every
school: the four ways to steer your motorcycle using countersteering, peg
weighting, outside knee pressure against the fuel tank and brake/throttle
application. These techniques work no matter what kind of riding you enjoy.
What
we teach our students is that these are not four independent methods to pick
and choose from; each method should be used in conjunction with the other.
COUNTERSTEERING:
is the act of pushing on the inside bar (or pulling on the outside) in order to
make the motorcycle initiate the corner. Push left, lean left…push right, lean
right. The motorcycle's front tire actually turns in the opposite direction of
the corner momentarily before the bike leans in and arches in the direction of
the corner. However, a rider that relies solely on the countersteering will be
at a disadvantage when compared to a rider that uses the four ways we teach.
If
a rider relies entirely on the movement of the handlebar/clip-ons to turn the
bike, he or she must use muscle at a place where you need maximum feel for what
the bike is doing. Let's use a tight left/right s-turn as an example. In order
for the motorcycle to transition through the corner using only countersteering,
the rider must use a firm grip, forcing the bars the then relaxing. This not
only becomes physically tiring when done repeatedly, but also works to upset
the chassis if done abruptly. We teach our students to get away from muscling
the handlebar.
PEG
WEIGHTING: think of a motorcycle as a big gyroscope, and at speed that gyro
wants to continue moving in a straight line. You've got gears turning, pistons,
wheels and brakes… multiple moving parts that make turning the motorcycle all
the more difficult. However, the footpegs are set low and act as an inside axle
of the gyro, where a rider can maneuver his or her weight and use considerable
leverage and pressure to affect how that gyro reacts. But peg weighting is not
just about placing the weight there, but when the rider places the
weight there.
OUTSIDE
KNEE AGAINST THE FUEL TANK: Using the outside knee against the fuel tank
leads to tightening of the torso muscles, which in turn allows the rider to
take the weight off the arms. Why is this important? Because anything that
helps alleviate a tense grip at the handlebar will help the rider receive
better feedback from the chassis and tires. And relaxed arms and hands are the
instruments of smooth throttle, brakd and clutch control.
BRAKE/THROTTLE:
The final part of the steering equation we teach at the Riding School involves
application of the brake and throttle. We teach that the most important aspect
of each corner is the entrance, dubbed Zone 1 in the school. Brake and throttle
usage in Zone 1 are essential to successfully navigating the rest of the
corner. Both brake and throttle input have a tremendous affect on how the
motorcycle steers when used in conjunction with the other methods.
Braking
for a corner loads the front tire, compresses the front suspension and tightens
rake and trail, allowing the motorcycle to steer more quickly. Trail braking
well past the turn-in point allows the rider to continue slowing the bike and
help it steer, adjusting the line if need be while maintaining the load factor
on the front tire. The throttle is used in much the same way; rolling it off
and squeezing the brake will cause the motorcycle's line to tighten, cracking
the throttle off idle after the brakes are released arrests the bike's lean
angle and helps hold the desired line.
One
of the reasons we use such a diverse methodology when teaching students how to
most efficiently steer their motorcycles is because a rider will use different
techniques depending on the situation. ON the race-track, a rider can hang off
the bike and use body and peg weighting more than on the street. During street
riding, more importance may be placed on countersteering and brake/throttle
application. But the important thing is to understand how all of these inputs
can be best utilized to help maneuver your motorcycle.
