The
pavement ends
Sooner
or later you are going to find yourself riding on a road where the
pavement has ended and stretched before you is crushed rock. You
tighten those pucker muscles and slow down, and you decide to keep
going.
Last
week a small group of us were confronted with just such a
challenge. The group consisted of a Magna in the lead, followed by
a Valkyrie, followed finally by my GoldWing. The lead bike,
Elaine, had asked if we all wanted to try it and she heard us all
agree to do so. She asked again about 1/4 miles into the stretch
because it was far more difficult than it had looked like it would
be. This, because some of those rocks turned out to be the size of
a small clenched fist. Again, we all agreed to keep going - but,
honestly, by then it would have been more dangerous to try to stop
and turn around.
I
was carrying a passenger on my GoldWing. Fortunately he has
accumulated about 3,000 miles on the back of my Wing and was game
for the effort. Had my passenger been inexperienced I would not
have attempted that road. Even a little squirming would have
resulted in loss of control of the bike.
There
were a pair of tire tracks where the rocks were more densely
packed and more uniform than the rest of the roadway. Each driver
elected to try to ride along one of those tracks. Since I had been
riding in the left track before the pavement ended I chose to stay
there. That decision, I now believe, was a mistake. More about
that in a minute, however so there is no suspense in the matter,
all three of us managed the problem without incident.
God
bless gyroscopic force! Though we would constantly find our tires
riding up and over large rocks, most of the time they tried
glancing blows with the rocks and found that the rocks would
squirt out to one side while the tire shifted laterally to the
other. We found that so long as our speed remained above about 20
MPH we could keep going but if we went any slower the bikes were
so unstable that it would be only a matter of time before dumping
them. Clearly gyroscopic forces made the difference.
On
the other hand, going too much faster than that was unthinkable.
This, because the bikes could not be kept on a straight line no
matter how much effort was used, and there was two-way traffic on
that road. In the event that one of the bikes found itself in the
path of an oncoming car there was nothing for it but to stop - and
the odds were high that the bike would fall down if we used ANY
front brake to try to slow down. So, we drove at a speed where
front brake was NEVER NEEDED.
I
have heard, as I'm sure you have, that if you drive a bike with
integrated braking (like the GoldWing) you cannot apply the rear
brake without applying the front one. Nonsense!
As
I already pointed out, trying to slow down by using the front
brake on such treacherous footing would probably have resulted in
a dumped bike. How do you use the rear brake without using the
front one? By using the engine for most of your braking. You drive
in a low enough gear so that you can roll off the throttle to slow
down and you can use your clutch friction-zone to moderate speed
precisely.
As
to picking which tire track to ride on if you have a choice, I
suggest that you select the right one. Despite trying to stay in
those tracks there were times when large loose rocks forced our
front tires out of them. You will recall that when riding into a
pool of standing water your motorcycle or other vehicle will feel
substantial drag and it slows down. Similarly, when your tire is
forced out of a relatively well packed tire track and onto the
more loosely packed roadbed nearby you will feel greater drag and
your bike will slow down.
That
happened more than a couple of times during the ride, but one of
those times was a white knuckler. My front tire was forced to the
left out of the track and the bike slowed down. Giving it a little
gas made the front-end a little lighter and just then it received
a series of glancing blows that pushed it farther and farther to
the left. Indeed, in a matter of 2 seconds I had moved FOUR FEET
to the left - directly into the path of an approaching truck! I
managed to SMOOTHLY force the bike over to the right and back into
the tire track I had left before that truck got too close to me.
In fact, I kept going and got into the right track. [I'm told by
my passenger that his eyes could not have opened more widely than
during those two seconds as he kept telling himself not to move.
He REALLY wanted to shift his weight away from that oncoming
truck, but wisely just held on. (See what experience and practice
can do for you?)]
After
returning to paved road the tension snapped back to normal levels
and riding once again was fun. At our first stop thereafter we
compared notes. Following is what we agreed to:
If you have a passenger who is either inexperienced or who has
not developed a profound trust in your abilities, do not
voluntarily attempt to ride on unpaved roads.
Drive in either 1st or 2nd gear so that you can use engine
braking as necessary and so that you can use your clutch
friction-zone to precisely control speed.
Do not drive slower than about 20 MPH in order to allow your
wheel gyroscopics to help you.
Do not drive much faster than 20 MPH so that you can totally
avoid using your front brake to slow down.
Do not 'white knuckle' your grips - you need to ride with a firm
grip on the bars, but you must be loose enough to prevent
transmitting all the instability of the front-end to the rest of
the bike.
EVERYTHING you do must be done SMOOTHLY.
Given a choice, ride in the right-most tire track to keep you
away from any oncoming traffic.
