The purpose of the exercise bike was
to replicate the physiological workload
of riding a motorcycle in an urban
environment. The actual workload was

experienced motorcyclists at the Honda
rider training centre at Kilsyth, Victoria.
Workload was determined by measuring
the riders’ oxygen consumption with
gas analysis masks (Metamax) to
establish the metabolic heat produced
while riding. Compared to their pre-

percent more oxygen while riding, and
used more in urban than rural riding.
In the climate chamber trials, this was
replicated by the rider cycling very
slowly, (60 rev per minute), in order
to produce the equivalent level of
metabolic heat as riding in an
urban environment.
The results from this series of
studies have established that thermal

suit in hot conditions (35°C) could

We also found this to be associated
with increased fatigue, mood change
and impaired cognitive performance,
each of which has implications for
rider safety.
In relation to the question of standards,
there is no intention or hidden agenda
to introduce mandatory standards
for motorcycle clothing in Australia.
A rating system on the relative injury
protection and thermal management
of motorcycle protective clothing is
currently being developed for Australia
and New Zealand. This is because
evidence suggests that rating schemes
are more effective than standards for
dynamically improving product quality.
Who buys a one star car
these days?Finally, on a different point mentioned
by your reader, Australia is not ‘in the
process of accepting the European
standard for helmets’, UNECE 22-05
is a global regulation for motorcycle
helmets, not “a European Standard”.
Liz de Rome
Deakin UniversityThank you for correcting the comment about
the helmet standard, Liz, but I’m afraid the
experiment still isn’t convincing for me as it
clearly wasn’t for our reader. Caesar’s wife
must be seen to be virtuous; experimental
results must be seen to be... what, common
sense? Always assuming they’re not about

Hey, Bear
Motorbikes come in much more
interesting and varied and bright
colours than cars. Why?
