Patch: The quick fix for the 4CS forks is to lower the fork oil
height in 5cc increments. It’s not so much a fix as a Band-Aid.
Part numbers: The anodized Husqvarna clutch cover is the
only engine part that is uniquely Husky’s.
( 2) Mesh screening. The MXA test riders remove
the mesh backfire screen from the airbox and the mesh
sound screen from the muffler. We suggest switching to
a fire-retardant air filter just to be safe. The reward is
improved throttle response.
( 3) Gearing. It’s not that we don’t like the gearing;
it’s just that the choked-off powerband doesn’t like it. We
have two suggestions. You can gear the Husky down
by going up one tooth on the rear, or you can gear the
FC350 up by removing one tooth from the rear sprocket.
Both of these choices come with rewards and penalties. If you gear it down, you will be able to get to third
gear sooner and the powerband will turn over quicker.
If you gear it up, you will be able to stay in second gear
longer, which will allow the engine’s 13,500 rpm rev
limiter to work to the max.
The MXA wrecking crew was evenly divided along
talent lines as far as gearing choices. The faster test
riders either stuck with the stock gearing or went one
tooth fewer on the rear. Why? They had the talent to
carry their speed and weren’t worried about bogging or
falling off the pipe on the upshifts. The Vets and Novices
preferred to gear it down to get through each gear with
more thrust, which allowed them to get to third gear
Q: WHAT IS THE REAL STORY BEHIND
MID-SIZED OPEN BIKES?
A: Before the KTM 350SXF was introduced in 2011,
a rider had to choose between a 250 and a 450. There
was no middle ground. Oh, you could send your 250F
out to have it big-bored up to 265cc, 270cc or 290cc,
but it was still a 250 four-stroke at heart. The 350 idea
germinated from the belief that 450s were too powerful;
however, the 350 movement wasn’t helped by the first
two years of KTM 350SXFs. They were slow. Then, KTM
began to kick out the jams, and the 2013 through 2015
engines became viable options for someone who wanted
Baby Bear’s porridge. Now a rider can choose a mid-sized
bike that makes competitive 450 horsepower but is still
ridden with a wide-open 250cc style.
Q: WHAT DID WE HATE?
A: The hate list:
(1) Air-filter cage. The air-filter cage does not
intuitively fit into Husqvarna’s airbox. There is a fairly
high chance of getting it misaligned.
( 2) Gearing. Most MXA test riders run 51 or 49 teeth.
Very few stick with the stock 50-toother.
( 3) Weight. The point of a mid-sized Open bike is
to complement the modestly powerful engine with a
supremely light and agile chassis. The Husqvarna FC350
may be agile, but it definitely isn’t light. It needs to lose
at least 8 more pounds to make the mid-size concept
come to fruition.
( 4) Shift lever. The shift lever is either too high or too
( 5) Airbox. An engine needs to breathe, but the
FC350 has asthma.
( 6) Rear fender. You will break the rear fender. How?
Just like us, you’ll forget to use the grab handles and
instead pick up the FC350 by the rear fender. As a
result, the plastic will snap and the fender will stand at
( 7) Subframe. The polyamide rear subframe is a
creative idea, but it bulges out in certain areas, causing
