This is how we set up our 2016 Suzuki RM-Z250
for racing. We offer it as a guide to help you get your
own bike dialed in.
KAYABA PSF- 2 FORK SETTINGS
Suzuki ran Showa SFF single-spring forks in 2013–
’ 15, but for 2016 they have switched to Kayaba PSF- 2
air forks. Suzuki’s version of PSF- 2 forks differs from
Honda’s in that the high-and low-speed rebound
damping clickers are on the top of both fork caps,
while the compression damping is on the bottom.
Honda has its high- and low-speed compression
clickers on one fork cap and its high- and low-speed
rebound clickers on the other. For hard-core racing,
these are MXA’s recommended 2016 Suzuki RM-Z250
Spring rate: 34 psi ( 35 psi)
Compression (bottom of fork): 7 clicks out
Hi-rebound (silver): 15 clicks out
Lo-rebound (red): 16 clicks out
Fork-leg height: Flush
Notes: Once you find the correct air pressure
setting for your weight, speed and track, focus on
making all the adjustments with the compression
clickers first, the low-speed rebound clickers second
and high-speed rebound last. Given our druthers,
we would prefer to have high- and low-speed
compression damping instead of Suzuki’s focus on
incremental rebound damping.
KAYABA SHOCK SETTINGS
For hardcore racing, these are MXA’s recommended
2016 Suzuki RM-Z250 fork settings (stock settings are
Spring rate: 5. 5 kg/mm
Race sag: 105mm
Hi-compression (blue): 9 clicks out
Lo-compression (silver): 10 clicks out
Hi-rebound (bottom of shock): 17 clicks out
Lo-rebound (red): 11 clicks out
Notes: The 5. 5 kg/mm spring might be a little stiff
for minicycle transplants, but use free sag as your
gauge. Check the race sag at regular intervals throughout the life of the machine. Don’t discount the shock
when it comes to handling. If it is too stiff or the
race sag too little, the RM-Z250 can go from a
sweet-handling machine to a yellow ogre. Balance the
front and rear with careful setup.
A: The like list:
(1) Cornering. There’s no bike in the 250 class that
can hit corners with more precision than the RM-Z250.
It’s confidence inspiring.
( 2) Couplers. We love plug-ins and prefer the white
plug-in. Enough said.
( 3) Suspension. We like the idea of low-pressure air
forks like the RM-Z250’s Kayaba PSF- 2 forks. Low-pressure
forks have a single air chamber that only requires 35 psi
instead of the TAC forks’ 170 psi. Kayaba PSF- 2 air forks
also come on the 2016 Honda CRF450. There is one major
caveat: On the Suzuki RM-Z250, the clickers on both fork
Mix-up: Most MXA test riders would prefer high- and low-speed compression clickers over rebound.
Kaleidoscope: The color-coded shock clickers make life easier once you commit them to memory.
caps are for rebound damping only (both high- and low-speed). The compression clickers are on the bottom.
Q: WHAT DO WE REALLY THINK?
A: It wasn’t that long ago that the Suzuki RM-Z250
won the “MXA 250 Shootout”—2011 to be exact. If the
2016 RM-Z250 engine is Suzuki’s engine of the future, it
will be a long time before Suzuki wins again. ❏
