There’s no better stock front brake setup than what’s found
on the KTM and Husqvarna motocross line-up.
The 4CS forks have some setup issues, but they are a big
improvement over the last decade’s WP bladder forks.

Q: WHAT CHANGES DID THE MXA
WRECKING CREW MAKE TO THE 2015
A: Here is a list of things that we changed.
Airbox cover. We Swiss-cheesed it.
Preload ring. When we eventually have the shock oil
changed, we will install a metal preload ring.
Shift lever. We placed the Husqvarna shift lever in a
bench press and bowed the middle of the shift lever to
raise the tip.
Air-filter cage. Never install the air filter without
double-checking to make sure that the back side is
Radiator cap. We run the radiator cap from the
Husqvarna two-stroke (you can recognize it from its
brass center). It is bulletproof; the four-stroke cap not so
Steering-stem nut. We run a Works Connection
nut because it has a hole in the center that allows the
gas-cap vent hose to spin freely.
Rear sprocket bolts. Never ride your Husqvarna or
KTM without checking the rear sprocket bolts.
Spokes. Always check the spoke next to the rear rim
lock; there is a 50/50 chance that it will be loose.
Q: WHAT DID WE HATE?
A: The hate list:
(1) All the things above. We don’t hate them with
a passion, but we hate them enough to change them.
( 2) Seat cover. It looks grippy, but it’s really slippy.
( 3) Fork guards. We loved the old wraparound fork
guards. They were a hassle to remove, but they
protected the back of the fork legs from rock dings.
The new fork guards look cool but aren’t as functional.
( 4) Rear fender. Do not, under any circumstances,
pick the Husqvarna FC450 up by its rear fender. It will
break if you do. Use the built-in handholds.
Q: WHAT DID WE LIKE?
A: The like list:
(1) Tires. The FC450 is spec’ed with Dunlop’s new
MX52 tire combo. Even though MXA typically runs
Dunlop MX32s on intermediate terrain, the hard-pack
MX52 is a good OEM tire choice.
( 2) 4CS forks. Okay, they aren’t the greatest forks
on the track in 2015, but we admire KTM for upping its
( 3) Fork adjusters. No need for a screwdriver or to
kneel in the dirt to adjust the damping. The clickers are
right in front of you.
( 4) Electric starting. Kick no more.
( 5) Hydraulic clutch. This is the longest-lasting
clutch in motocross.
( 6) Brakes. Honda and Kawasaki tried to close the
gap by going bigger in 2015, but the KTM/Husky
Brembo combination is still the best.
( 7) Shifting. The best-shifting transmission in
motocross. No missed shifts. No false neutrals. No
mystery shifts, and no refusing to budge at high rpm.
( 8) Cosmetics. Thanks to in-mold graphics and a
Swedish color scheme (even though this bike hasn’t been
