Riding
your Motorcycle in the Wet
"For
many riding their motorbike in the wet for even a short distance
is intimidating. It is in fact merely a decision"
|
I
pulled up at the robot this morning. The rain continued to
fall as it had done for three days previously. I heard a ’thump’
and the noise of plastic on asphalt as a biker sprawled across
the intersection in front of us all.
Within minutes we had him and his motorbike parked at a local
garage where he could wait for his wife to come and collect
him. Besides his one shoulder he was unhurt - possibility
he would be in worse shape once his wife got hold of him!

For
the purposes of discussion (and not for blame) there are a
good number of things about this accident that deserve to
be mentioned.
The first and most obvious, was the huge oil (or diesal) spill
on the road at the intersection. The shape and distribution
of the spill screamed one thing - the spill was not accident!
It had been planted earlier that morning by the vulture who
mysteriously appeared out of nowhere seconds after the bike
came to an untimely halt (vulture - an independently owned
tow truck driver). Any leaking truck using the intersection
would have deposited the oil in a logical way as it passed
through. This spill was random and illogical throughout an
large area around the entire intersection. There was nothing
to be gained in accusing the dog and he disappeared as quickly
as he arrived once he realised that no business would come
his way.
Secondly, the biker was onboard a light off road bike with
enduro tyres. This is not the ideal commuter as these tyres
offer no traction in wet weather on a hard surface. Deflating
them by 25% does help however when faced with no other alternatives

The biker rode downhill into the intersection. Braking on the downhill
is always a problem even in dry weather. With poor training the
rider can pitch more weight onto the front wheel than is needed
thereby stressing the already limited traction. When braking under
these conditions it is important to brake early, sit upright, grip
the bike with your inner thighs and relax your arms - this keeps
your body weight off the handlebars while braking.
For the biker, snapping the brakes on (whether the front or the
rear) was a survival instinct when the robot suddenly changed to
red. This is difficult to fight in practice. Linked brakes and ABS
systems go a long way in cancelling out this problem. In a perfect
world, bike brakes are always applied progressively. This way the
tyre traction increases throughout the braking process (especially
true of the front wheel)
|

The
rear brake should be applied first in the wet. The back
brake must work harder. Sitting upright as possible and
an under inflated rear wheel does increase its traction
under braking. If the back wheel locks up and the bike begins
to fish-tail, no problem - LOOK UP, LOOK AHEAD, RIDE STRAIGHT.
’Forget’ about the rear wheel and start progressively applying
the front brake - even in the wet it offers more stopping
power than the rear if applied progressively.
The bike in this incident bore all the typical signs of
a crash - broken controls. The controls i.e. handlebar levers
and foot levers always take a pounding during an accident.
This is why during long distance, rural touring always take
a spare clutch lever mechanism and gear lever. If you cannot
operate your gears you will be looking for a ride to the
nearest town for both you and your bike with a possible
long wait for spares. Things like damaged turn indicators
can be repaired by duct tape (repair tape) and should be
an essential part of a touring bikes essential equipment.
The rider mentioned walked away with only an injured shoulder
and dented pride. This is where his protective clothing
came into its own and saved his bacon.

Fact is, all bikers will find themselves separated from their pride
and joy and dumped on the asphalt at one time or another. For some
however it happens less frequently than for others
