The Suzuki's weight was another
factor that held it back against its
classmates, and while the FMF ex-
haust might have moved the needle
in the right direction, it obviously
doesn't render the entire difference.
That being said, a quicker-revving
engine can notably affect how heavy
a bike feels. Mellow power can
make it seem heavier whereas
crisp, responsive power can make
it feel much lighter on its feet. The
brighter power gives the RM-Z a
lot more pep, and any extra weight
is suddenly less of a factor.
More power on tap adds quite

but is it enough to boost it to
a more competitive level in its
class? On its own, not quite.
There still stands the greater chal-

It was time to take a look at
the Kayaba PSF2 air fork. This
is where task got a little more

unlocking power on
the RM-Z.

There's no miracle fix
for the KYB PSF2 fork,
but Precision Concepts
made some good
performance gains that
make it much more
manageable.
