When MXA tested Jason
Anderson’s Rockstar Energy
Racing (RER) Husqvarna FC450
Supercross bike for the April
2015 issue, we planted the bug
in crew chief Steve Westfall’s
ear about testing an RER Husky
FC250 outdoor bike. He kindly
obliged and gave us pick of the
litter. Naturally, we chose Zach
Osborne’s steed for several
reasons. (1) We have known Zach
since he was a snot-nosed brat
in the mini-cycle class. ( 2) We
have a soft spot for a guy who is
willing to represent his country
and race the MXGP circuit. ( 3)
Given that the bike would be
loaded in the semi and transport-
ed to a test track of our choosing
directly after the second moto at
Hangtown, we wanted the bike
that had the least chance of get-
ting beaten up during the race.
Two days after the opening
National of the 2015 season, we
met Steve Westfall and Osborne’s
mechanic, Dave Feeney, at
Milestone motocross park in SoCal.
Feeney had pressure-washed the
Husqvarna FC250, but aside from
that, the bike was untouched.
This was the real deal, evidenced
by the torn graphics and pockmarked front number plate. We
were immediately captivated by
the works brakes, carbon fiber
headstays, steering damper and
massive fan tucked behind the
right-side radiator. Below are
some pertinent answers to
general questions regarding Zach
Osborne’s Rockstar Energy Racing
WHAT’S THE TRICKEST
PART ON OSBORNE’S BIKE?
Beauty is in the eye of the
beholder. One MXA test rider lust-
ed after the WP 52mm Cone Valve
forks and Trax shock, yet the fac-
tory suspension barely registered
a spike in excitement for other
testers who drooled over the radi-
ator fan system that automatically
turns on when the coolant reaches
a certain temperature (more on
that below). Since our testers liked
every part on Osborne’s bike, we
asked the RER staff what they
thought was the trickest part.
Their answer? The factory brakes.
Zach relies on a works Brembo
front brake, outfitted with a 28mm
piston and 260mm Galfer rotor for
optimal modulation and maximum
stopping power when needed.
Note that the Brembo front and
rear brakes can be purchased
through the Husky Power catalog.
WHAT’S THE MOST
UNIQUE PART ON
OSBORNE’S BIKE? Again, there
are too many parts to choose from,
so we’ll provide an abridged list of
Osborne’s most unique parts.
(1) Titanium fasteners.
Met-Tek makes specialty titanium fasteners for the RER team.
Ti bolts are used to the point of
excess, but the team also uses
common sense. For example,
they don’t use titanium linkage
or shock bolts because these
bolts take a lot of abuse. Also, it’s
cheaper to throw out a $10 steel
bolt than something that saves
