Bridgestone classifies the A41 as a 90:10 for
more road-focused riding but still with the
ability to traverse most of the dirt roads you'll
encounter on your next adventure.
The biggest visual difference between the
A40 and the A41 is the vastly different tread
pattern, with the A41 sporting a much more
aggressive design. The aim here was to
disperse more water via an increased sea/
land ratio in the shoulder, while spacing out
the grooves in the center of the tire and al-
lowing for the use of the dual compound front
for longer mileage, which is a first for any
Bridgestone adventure tire.
"For Bridgestone, this Adventure A41 was a
complicated development," said Fabian Fran-
cois, Field and Product Planning Engineering
for Bridgestone Motorcycle tires. "What is
difficult in this segment is, most of the time,
the maxi trail bikes the have fully loaded lug-
gage and a high front end, with 19- or 21-inch
wheels, and this makes it quite complex in
terms of tire setup."
One of the biggest development goals with
the new Adventure A41 tire was to increase the
high-speed stability, an area the old tire was
not exactly lacking but needed a little boost.
These kinds
of dirt roads
are about the
maximum you'll
want to push
an A41—and
it will perform
brilliantly
when you do.
The rear compound here
shows the three-compound
Cap and Base design. The
harder center compound
(yellow) forms the
foundation for the softer sides
to be layered over the top,
increasing carcass stability
and stiffness when cornering.
