top-quality beadlock wheels, and he
uses the TireBlocks run-flat system
in each of them. TireBlocks ensure
that he can finish each race to his full
potential, regardless of whether or not
he flats. TireBlocks are completely
vibration-free and even help with finding traction in slippery terrain.
GETTING A MONSTER MOTOR
Amazing holeshots are another
thing we’ve seen out of Dillon this
year. While a lot could be credited
to his tire choice and ideal traction,
we all know it takes serious motor to
holeshot the pro line. TD Powersports
builds Dillon a crazy-fast motor using
titanium valves, porting and custom
head work for higher compression.
The motor package is a complete
rebuild that upgrades or replaces/
modifies all the necessary top- and
bottom-end parts needed to reliably
race at the pro level. The engine
package is available to the public
through Goldspeed Products
EFI tuning is handled by Can-Am.
Can-Am race programs the stock ECU
for optimal fueling/power, and it is all
spent out of a titanium FMF exhaust
system. The motor is lubricated with
Motul’s top-quality race oils, and
they have come up with a custom
welded-in bypass on the stock radiator system to lower engine operating
A large-capacity desert tank is not
PROTECTION AND COMFORT
available, so they run a custom 4-gal-
lon aluminum one built especially for
WORCS. SSI Decals makes Dillon
one-off graphic designs that are sure
to stand out in any crowd, showcas-
ing all those sponsors that are helping
him get to the podium. Quad Tech
provides custom-sewn seat covers,
and the DS is further dressed up with
CV4’s brightly colored silicone radia-
Aluminum protection is handled
with Rath Racing bumpers, and Dillon
prefers the all-inclusive Rath Racing
Signature Series nerf bar. This nerf
bar/heel guard/peg setup features a
netted nerf bar, heel guard and super-gnarly stainless steel footpegs. The
stainless steel footpegs will last entire
seasons without wearing out, and
chromoly mounting ensures that the
rest will stand the test of time too.
Setup and controls are usually
determined by personal preference.
Dillon swears by Precision Racing
Products and has run Precision’s
Stabilizer for years. The stabilizer provides unmatched control and stability.
They started testing with Precision’s
Shock & Vibe handlebar clamp as
soon as it hit the market. The Shock
& Vibe clamp lets your bars free-float
slightly with adjustable tension. This
product really helps with forearm
pump and control late into the two-
hour WORCS motos.
Dillon runs a Tag handlebar with
a Works Connection perch that is
adjustable on the fly, and uses a
bearing system for the clutch lever to
pivot on. He grew up racing with twist
throttles, but made the switch to a
thumb-throttle setup a few years ago
for better control in the corners. Even
after four years, he finds his thumb
getting sore and has recently started
removing the throttle spring for an
even lighter pull.
Looking at Dillon’s bike, it is pretty
cool to see that you can actually buy
everything needed for a champi-onship-quality machine. Can-Am is
really putting a lot into the sport of
ATV racing with contingencies and
producing near-race-ready machines.
JB Racing front A-arms work with JRI ECX1 ATV shocks to deliver optimal suspension performance, as the high- and low-speed compression damping circuits
are completely independent. Dillon prefers the strength and adjustability of the
French Beringer front-brake master cylinder, and caster, camber and toe are
set with laser alignment.
Can-Am has a strong European connection from the Bombardier/Rotax
early days, and Dillon continues the trend with Motul oil and lubricants, JRI
shocks with dual-rate springs and adjustable cross-over, Beringer brakes, and
Goldspeed tires. Check out the knurled rebound-adjuster ring on the bottom
of the shock.
Pro ATV racers are particularly concerned with the handlebar setup, and Dillon uses Tag handlebars with
Precision Shock & Vibe damped-bar mounts and steering stabilizer, and a JB Racing steering stem with
special flag stop. The 4-gallon aluminum fuel cell is the only “unobtainium” on Zimmerman’s sled.
