The little things can become very irritating. Works
Connection’s stem nut stops the vent hose from twisting.
Ride Engineering makes special KTM axle blocks that accept
a Honda CRF450 rear axle. The trick is in the axle blocks.
Pro Circuit’s 1.25mm longer pull rod not only stiffens the
initial part of the shock stroke, but lowers the seat height.
These NK SFS air triple clamps aren’t just like Ryan Dungey’s,
they are Ryan Dungey’s. They offer 10mm of handlebar travel.
( 5) Gearing. I run a 52-tooth rear sprocket, not because
I want the KTM 350SXF to hit harder, but because I want
to get to third gear sooner and stay there longer. Gearing
it down allows me to run a taller gear and take advantage
of its longer pull.
( 6) Battery. I have an aftermarket EarthX battery in
my bike—not just because it is a little lighter, but because
I carry a spare battery with me to every race; thus, I use
the stock Yuasa lead-acid battery as a backup. You may
never need it, but I have.
( 7) Fuel filters. Any time the KTM 350SXF gets hard
to start, I check the fuel filter in the gas line and either
back-flush it or replace it. The 50-psi fuel system doesn’t
like an impedance in the fuel system.
( 8) Fuel-pump relay. I zip-tie the KTM’s fuel-pump
relay to the frame. It has a habit of coming loose and
rattling around enough to short it out. Zip-tying it is a
( 9) Shift lever. KTM’s shift lever is too low, but if you
move it up one notch it is too high. To solve this problem
I place the shift lever between two blocks on a bench
press and bend the tip up 5mm. Amazingly, that little
bit of room is enough leeway to get a boot under the
( 10) 7602 brake pedal tip. The 7075 aluminum brake
pedal tip from 7602 Racing not only has more aggressive
teeth and a brake snake hole, but it has three adjustable
mounting positions. I much prefer to have a longer brake
pedal where I can have a more tactile feel from my foot.
( 11) Suspension. I have always believed that the best
suspension guru is the one whom you have a relationship
with. A guy who has done your bikes before, comes to the
racetrack occasionally, and will redo your valving if you
aren’t happy is the best suspension guy for you. I have a
30-year relationship with Pro Circuit’s Bones Bacon. I trust
him to get me where I want to be, even if it takes three
or four re-valves to make it happen. For my KTM 350SXF,
I had him duplicate my 450SXF valving but go with
lighter springs. He had to make some adjustments after
his first try, but he made me happy. I’m not saying you
need to go with Pro Circuit; I’m saying go with someone
who will help you until you are happy. I’m happy.
( 12) NK SFS air triple clamps. I love these triple
clamps, and mine came straight off Ryan Dungey’s works
bike. Equipped with two small air shocks that double as
the handlebar mounts, the French-made triple clamps offer
almost a 1/2-inch of suspension travel for the bars. I’ve
raced with them since October of 2013, and they have
been bulletproof. There is a learning curve to getting the
correct air pressure, but once you find it, all you have to
do is reset it before each race. I run 70 psi.
( 13) Works Connection stem nut. When you remove
a KTM gas cap, the vent hose gets twisted. Given how
often I fill my bike or check the gas, the twisted vent hose
is a major irritant. Works Connection makes an anodized
KTM stem nut that has a hole in the center of it so that
the vent hose can be inserted into it like on a blue, green,
yellow or red bike. It just makes day-to-day life simpler.
( 14) Think seat foam. I like KTM seat foam when
the bike is new, but with every ride the foam gets softer
and softer. I’m sure there are lots of other aftermarket
seat foams that would solve this problem, but the vast
majority of works bikes run Think seat foam. Not only
does it feel good, but it has a longer life span. Oh yeah,
it saves almost a pound over the stock seat foam, which
is why Dungey, Roczen and Musquin use the same type
of foam. My seat cover of choice was a used, 450SXF-FE
Factory Edition, textured seat cover.
( 15) Subframe. I have short legs to go along with my
