Based on what I observed during my trip by car
and my experience with motorized two-wheeled vehicle travel elsewhere, I think this would
be a challenge indeed! There are long stretches of soft gravel that are tricky
even in a car. I saw a guy on a Harley leaving Churchill Falls, struggling very
hard to remain upright as he tried to ride through the soft gravel. He was obviously
very nervous, and wasn't going faster than walking speed. There was no choice,
though -- there were no bare patches to ride along.
If you do go on a motorbike, please ride very
carefully, and be very alert for "surprise" soft gravel patches.
Also, be very visible, since the dust clouds raised by passing vehicles can
you until they settle, which is sometimes quite awhile.
Gas up whenever possible, even though the longest
distance between gas stations is 290km, just in case.
Remember that this is a remote area.
This could be a challenging trip to do by bicycle due
to the remoteness of the area. Other vehicles would be a hazard as well, as they
spew out gravel as they pass. The long stretches of unpaved road would be a
challenge as well. Be careful and be visible.
Water: You will need to either drink
the water from the streams and rivers as is (not recommended) or carry some sort
of water purification device.
