Suzuki’s Single Side Function (SSF)
Showa fork has potential, though it
came valved flat weird. We know that if
you bolt on an RM-Z250 unit suddenly,
the action goes from harsh and stiff to
smooth and flowing.
Both the Honda and the Kawasaki’s KYB
air fork offer excellent action in both
arm-jarring hack and soaking up the big
hit. They do require additional setup and
constant checking during an outing.
The CRF’s dual exhaust is unique in the
field and offers a mellow exhaust note.
It’s going to take a lot to make us swap
We’re not sure how the KX450F passes
any sound-level checkpoints. It’s gnarly
In a field where there have been major
amounts of suspension evolution, the
YZ-F’s KYB fork received the best
marks in the shootout.
The KTM has a nice access air filter,
super-strong driveline (chain sprockets
guides), and hidden on the back side of
the cylinder is a very small starter motor
for the electric-ignite starting function.
