Road
racing is probably
the most adrenaline pumping form of road-based racing.
It demands concentration, skilled machine control, bravery,
and fitness. Riding fast on a motorcycle is a tremendously
exhilarating and challenging game. In this game of rules
and barriers -- theres something to win, something
to lose and a purpose for each individual who plays
the game.
The
life span of most racers in this sport is 3 to 5 years
before they retire, due to injuries, lack of money,
etc. There is a danger however, that you may become
addicted to the sport and all your waking and sleeping
hours will be taken up with racing and how to stretch
your resources to go racing.
Going
fast on the street can be dangerous. Oncoming traffic,
blind motorists, radar guns, and blond-SUV-driving-soccer
moms on cell phones all pose threats...The track posts
its own set of challenges. Imagine yourself as a jet
fighter pilot
Now imagine doing it six inches off
the ground. At 150mph, it is just you, your rocket ship
and 30 other guys who want your position. No matter
how many riders are on the track, you must still rely
on your own ability -- Your ability as a racer to interpret
the specific unique track
a track in which the
designers have purposely constructed the course to create
changing situations at every turn.
An
abundance of racing theory has been developed in the
last 70 years. What was true then is not necessarily
true today. Physics and natural laws have not changed
tires and suspensions have. In the 50s
and earlier, riders were limited by the lack of sophisticated
technology. With the introduction of new materials,
products and application methods, riding styles have
changed dramatically; yet, outdated rider information
still confuses us. A riders style includes how
well he accomplishes each of the parts of riding. It
is all of what he understands and all of what he doesnt
feel good about rolled into his own package. People
are not born good or bad riders, riding skill is learned.
You must make hundreds of decisions while riding just
one lap of a racetrack or stretch of road especially
when riding fast. What you do is what happens, what
you dont do doesnt happen. Motorcycles
dont do anything by themselves. They dont
win races or lose them; they dont make mistakes
or do anything right. Everything that happens during
a ride depends solely on the rider. There is an actual
technology to riding.
Created
in 1974, Texas
Central Motorcycle Racing Association (CMRA)
sanctions, organizes and hosts area race events. CMRA
offers a riders school teaching riding technique
in the classroom and hands-on practice skills on the
track. Rider's Schools are available on the Saturday
of most event weekends. Successful completion of a Rider's
School course is mandatory for all would-be racers and
suggested for anyone wanting to become a better rider.
Everyone
knows that racing is a dangerous sport. Racers accept
and manage that risk. A critical part of risk management
is proper bike maintenance. Don't add to your risk by
riding a motorcycle in poor condition, or your bike
could wind up hurting you or someone else.
Proper
preparation and maintenance are the keys to getting
the most enjoyment from your investment of time and
money. A poorly prepared machine is unsafe. You can
expect the tech inspector to be very unsympathetic when
examining a dirty or neglected motorcycle. Any vehicle
that is raced undergoes serious stress. When you race
a motorcycle, you will punish your machine. Being competitive
in a race means that you push your machine to its absolute
limits. This applies equally to the motor and the chassis.
Because of this, you need to make sure that your bike
is in the best condition that it can be.
Before
the race, race prep will take up all those off-work
hours between practice sessions, (and football widows
thought they had a complaint!) The conventional wisdom
is that you should start on small bikes, and learn to
ride before you get enough horsepower to really hurt
yourself. In the US, the most popular starter racing
bikes are the Suzuki SV650, Kawasaki EX-500, the Yamaha
FZR 400, the Honda Hawk GT-650, and Your Current Street
Bike.
Then
comes the stripping off all the street stuff (lights,
signals, kickstands, etc), replacing the radiator coolant
with water, safety-wiring anything you wouldn't want
to come loose at speed, putting on number plates, adding
a steering damper, etc. The MARRC
Roadracing School Bike Prep Guide offers a good
bike prep guide.
Weight
is directly related to horsepower. It is estimated that
every seven pounds you eliminate, gains one horsepower.
Try to get rid of any extra metal on your bike that
you don't need, like passenger seat supports, chain
guards and lighting fixtures. Unsprung weight is any
weight that is not supported by the suspension -- typically
the swing arm, wheels & wheel components, chain
& sprocket and brake calipers. There are many benefits
to reducing unsprung weight. One of the most noted is
that, 1 kg of reduction in unsprung weight is approximately
equal to 6kg reduction in sprung weight.
One
easy way to reduce unsprung weight is the use of lighter
weight wheels. By reducing the weight of the wheels,
you also reduce the gyroscopic effect. The gyroscopic
effect is the force that is generated from a spinning
object. To get an idea of what this is, hold a bicycle
tire in your hands and spin it. Now try and change the
direction of the wheel. You will notice it is hard to
do especially if the wheel is heavy. By reducing weight
in the wheels you will reduce this effect resulting
in better handling during cornering and improved acceleration.
Magnesium wheels are the choice for most Superbike racers,
and some are even going to carbon fiber but these are
very expensive and typically not as durable as cast
aluminum.

Of
course, it's simpler if you buy a bike that's already
being raced in the class you're going to join--that
way all the grunt work of race prepping has been done.
Equally
important to a race-prepped bike and license -- protective
gear is vital. The old adage about two kinds of motorcycle
riders, those that have been down and those that have
yet to go down, probably originated on the track. Chances
are good you are going to crash and going to break bones
collarbones,
fingers, hand-bones, wrist-bones, foot and anklebones
theyre all susceptible in when you separate
from your ride. Serious weight leathers with foam padding
and hard plastic body armor, boots, race gloves and
a good helmet are essential. Buy quality or youll
pay the difference in medical bills. For quality on
a budget, check out www.newenough.com
offering brand-name closeouts and used gear.
Your
fitness level determines how long you can go, before
your awareness levels are lowered to the point that
you only react after the fact and not as a problem starts.
The longer the races, the more demand there is on your
mind and body to stay at its highest potential. Perhaps
the best reason to get into shape comes from some research
into obesity. This showed that on average, for every
12 pounds a man is over-weight his penis is effectively
shortened by half an inch due to the hanging mass of
fat. (Im not exactly sure what that reference
specifically has to do with road racing
)
Basically
we believe that its perfectly okay to find your own
lifestyle / fitness balance. On one hand we have our
desired lifestyle (which for us includes drinking vast
amounts of beer) and on the other hand we need to get
ourselves in a good enough state of tune to perform
acceptably well in our chosen sport(s). Lets be
honest, if you are out of shape you are much more likely
to become fatigued, and if you become tired whilst in
a dangerous sports environment, you'll be much more
susceptible to injury, hmmm... make that serious injury!
Taking it a step further there also the argument that
the more fit you are, the quicker you will be able to
return to your chosen sport after an injury. Fundamentally,
the more fit you are, the better equipped you'll be
for participating and competing in dangerous sports
and activities.
When
your job description on race day entails flirting with
the limits of tire adhesion
accidents are bound
to happen. The money you saved by not insuring the track
bike would be wisely spent on a medical policy that
covers you in case of track injury. American Motorcycle
Association offers a policy, appropriately named ARMOR
that covers you during participation in AMA sanctioned
events. A race weekend may run you $500 for entry fees,
food, fuel and tires, but a race injury can bankrupt
you.

As
a spectator, the lean provides the ooh and ahh responses.
For the racer, the lean is determined by turning geometry,
t= arctan [ v^2/(g*R) ] v is your velocity, R is the
radius of your turn, g is the gravitational constant,
t is the "lean angle." It's the angle between
the horizontal, and a line from the contact patch of
your tires through the center of gravity of the bike-rider
system. By sliding off the inside of the seat, the riders
body weight is moved towards the inside of the corner.
This means the bike needs less lean for a given speed
and turn radius. As ground clearance is often the limiting
factor in cornering (particularly at higher speeds)
this allows the rider to corner at higher speeds.
At
lean angles below 45 degrees from the horizontal, tires
no longer purely roll and are rotating more about a
vertical axis rather than a horizontal one. This makes
them act more like a rotary brush of a street sweeper
than a rolling wheel. With steep lean, the contact patch
twists in place scrubbing away traction and power so
that leaning farther reduces cornering ability and ultimately
causes a washout in the turn.
Racing
motorcycles takes a special type of rider, a special
type of machine, large amounts of practice and even
larger amounts of skill. Purebred race machines compete
on closed, paved road courses, piloted by races intent
on one thing, getting to the checkered-flag first. Take
a Saturday or Sunday, venture out to Oak Hill
(Henderson) Texas World Speedway (College Station),
MotorSport Ranch (Cresson) or Hallett Raceway
in Oklahoma and experience the thrill of high-speed,
two-wheel pavement action. From local clubs to world
championships, motorcycle road racing is the best time
you can have with your leathers on.
