This is how we set up our 2016 Yamaha YZ250X
for the motocross track, since the stock settings were
close to perfect for offroad conditions. We offer these
setting to help steer you in the right direction.
KAYABA SSS FORK SETTINGS
Most MXA test riders stayed close to the stock
clicker settings (after we added 10cc of oil to each
fork leg), with the faster riders going in two to five
clicks. For hard-core racing, we recommended this
setup for the 2016 Yamaha YZ250X (stock specs are in
Spring rate: 4. 3 N/m
Compression: 9 clicks out ( 13)
Rebound: 10 clicks out
Fork-leg height: 5mm
Notes: The SSS components feel as if they do not
bottom out. It was a huge confidence booster for all
conditions. For motocross we added 10cc of oil to each
fork leg, which is exactly what we did on our Yamaha
KAYABA SSS SHOCK SETTINGS
Our testers liked the movement on the shock but
felt that it was a bit under-damped. They went in a
few clicks with the rebound and compression to slow
it down and keep it up in the stroke. For hard-core
racing, we recommend this shock setup for the 2016
Yamaha YZ250X (stock specs are in parentheses):
Spring rate: 48 N/m
Race sag: 100mm
Hi-compression: 1-5/8 turns
Lo-compression: 9 clicks out ( 12)
Rebound: 9 clicks out ( 11)
Notes: The shock is the same as the YZ250’s,
including the spring rate. The only thing different is
the shim stack, which can be firmed up with
compression and rebound clicks. ❏
four-strokes—only that when unreliability rears its ugly
head, a two-stroke owner spends less dough on pistons,
rings and gaskets—and can put them in himself.

Japanese manufacture has made an offroad two-stroke
Q: WHAT DO WE REALLY THINK?
A: This is a jack-of-all-trades bike. You could race a
three-hour GNCC race, take a leisurely trail ride through
the woods, and when you got to your local motocross
track, you could bust some moves. The 2016 Yamaha
YZ250X is a very versatile machine. Maybe it’s not as
well-spec’ed for offroad riding as its orange competition
or as good at motocross as it blue brother, but Yamaha’s
YZ250X two-stroke and YZ250FX/YZ450FX four-strokes
are watermark machines. They signal that Yamaha is
serious about dirt bikes again.
Fuel miser: Although Yamaha didn’t put a larger gas tank on
the YZ250X, they did add a reserve valve to get you home.
Stepchild: The YZ250X forks are not junk forks from the
left-over parts bin. They are true-to-life Kayaba SSS forks.
Skinny Minnie: Yamaha redesigned the YZ250 expansion
chamber so that it would tuck in tighter on the YZ250X.
