KTM 450 SX-F
For 2019, KTM has taken inspiration for its
standard model 450 SX-F from last year's
Factory Edition in order to boost overall
performance. The most significant changes
included an all-new frame with increased
torsional rigidity for more precise handling, a
beefed up triple clamp, a lengthened subframe
and revised internal suspension settings.
Engine work includes an updated cylinder
head, which is said to improve performance
while reducing weight. KTM's "Ready to Race"
mantra holds true more than ever.
SUZUKI RM-Z450
Suzuki's RM-Z450 has always been praised
for its stand-out handling and cornering
capabilities, which the Hamamatsu
manufacturer looks to take even further in
2019. Engineers reduced the spring rate of
the Showa Balance Free Cushion rear shock
for improved balance, as well as revising
clicker settings front and rear. Aside from
that, the Suzuki remains identical, meaning
it grows even longer in the tooth. No electric
starter, tame horsepower and a dated
coupler system. The writing is on the wall.
YAMAHA YZ450F
The 2018 model year saw a complete
overhaul for the YZ450F. Now, the boys in
blue are back with several updates in hopes
that they can reign supreme for the first
time since '16. Revisions to the YZ began
with an updated electric starter system,
which is said to reduce drag and horsepower
loss. Complementing that change are new
KYB suspension settings, redesigned fork
lugs, axle brackets and wheel collars—all in
hopes of improving chassis feel and traction
while tipped into the corner.
