FC350 SETUP SPECS
This is how we set up our 2017 Husqvarna FC350
for racing. We offer it as a guide to help you find your
own sweet spot.
WP AER FORK SETTINGS
The air pressure on every AER fork varies from
Husqvarna model to Husqvarna model. The TC125
uses 125 psi. The TC250 has 148 psi. The FC250 and
FC350 come with 154 psi, and the FC450 is set at 156
psi. But, don’t think that you are locked into those recommended numbers. MXA test riders’ air-pressure settings vary from 135 psi to 160 psi—and slower riders
have lowered the oil height by 10cc to get the forks to
feel even plusher. These are incredibly tunable forks,
so don’t be afraid to play with them. For hardcore
racing, we recommend this fork setup on the 2017
Husqvarna FC350 (stock specs are in parentheses).
Spring rate: 140 psi ( 154 psi)
Compression: 20 clicks out
Rebound: 15 clicks out
Fork-leg height: Third line
Notes: Slower or lighter riders might have to lower
the oil height in the damping leg by 10mm or more to
get full travel. Additionally, we check the air pressure
between motos to ensure that the ambient temperature hasn’t raised our favorite settings. It is important to bleed the outer chamber constantly, which is
accessed via a 10mm hex head or #20 Torx. Even
if you own a #20 Torx, don’t use it on the air side,
because it strips out easily.
WP SHOCK SETTINGS
Last year we swapped all of our 48 N/m springs for
the lighter 45 N/m springs from the FC250. For 2017
Husqvarna is lowering all of its motocross bike spring
rates, which means that the 2017 FC350 will have a 42
N/m spring stock. If you are around 180 pounds, you
might want to go to a 45 N/m spring. If you are over
200 pounds, you will probably want to return to the
48 N/m spring. For hardcore racing, we recommend
this shock setup for the 2017 Husqvarna FC350 (stock
specs are in parentheses).
Spring rate: 42 N/m
Race sag: 105mm (110mm)
Hi-compression: 1-3/4 turns out ( 2 turns out)
Lo-compression: 15 clicks out
Rebound: 10 clicks out ( 15 clicks out)
Notes: We turned the high-speed compression
damping in a little to lessen G-outs and ran a touch
more rebound than the recommended setting.
Additionally, we set the sag at 105mm instead of the
WP-recommended 110mm. ;

loves the MX3S (previously called MX32) tires that come
stock on the 2017 Husqvarnas, especially the front in comparison to the MX52 that was OEM equipment in 2016.
But, be forewarned, if you push the MX3S front out of its
intermediate terrain, you will begin to lose side knobs on
the front tire. Oh, don’t get us wrong; it works well on hard
terrain, but not for long.
Q: WHAT DID WE LIKE?
A: The like list:
(1) Handling. This is the bike that all other bikes need
to be compared to. It’s a dream to ride.
( 2) Hydraulic clutch. If you’re a clutch abuser, this
clutch can take a beating without whimpering.
( 3) Weight. You have to be impressed by the 221-pound
weight. This is an impossible dream achieved with a battery and electric starter.
( 4) Powerband. Even though the MXA wrecking crew
thinks that a 375cc, 380cc or 400cc displacement would
come closer to fulfilling the dream of a mid-size Open-class
bike, the FC350 is the ultimate expression of a 250 on

hour meter on its bikes at the factory—and saving us the
Q: WHAT DO WE REALLY THINK?
A: If you are thinking of moving up from a 250 or
down from a 450, there are only two 350cc choices—the
KTM 350SXF or Husqvarna FC350. First introduced by
KTM in 2011, the 350 concept has taken seven years to
come to fruition. Once a novelty bike, the 350 is now the
ultimate Vet bike, and it’s rapidly becoming the first choice
for professional practice riders. What makes the 2017 350
such a good bike is the addition of WP AER air forks.
When you combine these forks with the amazing electric
starter, bulletproof hydraulic clutch, creative air filter, awesome brakes, superb handling, 54 horsepower and value
in every part, this bike should be on the wish list of every
racer over the age of 30.
