Toyota Introduces Concept Bike At 2009 SEMA Show
The Joe Gibbs Racing Motocross/Toyota (JGRMX/Toyota) Concept Bike
is a special one-of-a-kind project built specifically for the 2009
SEMA show. The JGRMX/Toyota motocross partnership, in conjunction
with the Joe Gibbs Racing Toyota NASCAR group teamed up to make the
special bike a reality. The group logged more than 100 man hours on
the project, and received modifications and accessories provided by
17 contributors to create a truly unique machine. The JGRMX/Toyota
Concept Bike illustrates how far customizing can be taken, when
combining a creative style concept with the latest in MX hardware,
and some dedicated and talented technicians.
The project started out using a 2009 Yamaha
YZ450F as the base platform to work from. The group utilized a
specially lightened and polished frame, and installed carbon fiber
body panels, and a custom fuel tank. Titanium and other exotic
metals were used, where appropriate, to further reduce weight and
provide an exotic appearance.
Cycra
Racing supplied the front and rear fenders, and the front
number plate. Lightspeed Performance
Products pitched in with a carbon fiber chain guide, rear brake
caliper cover, and fork guards to follow the carbon fiber body
design theme. N-Style contributed the seat
cover and exterior graphics.
The YZ450F
engine was treated to a reversed location valve train from
Xceldyne. Reversing the intake and exhaust valves on the cylinder
optimized the bikes balance point. Further induction modifications
included a fan-driven forced air intake system with fuel injection.
A Carillo rod coupled with a piston and rings were installed to
complement the top end work. Conventional radiators were dismissed
in favor of a custom aluminum extrusion cooling system. The use of
a special air driven starting system with an air tank integrated
into the frame was another departure from tradition.
Final engine additions included Filtron air and oil filters,
an FMF Racing exhaust system
tipped with a light-weight carbon fiber muffler, Brown & Miller
Racing Solutions brake and oil lines, a custom Toyota logo clutch
cover, and clutch internal parts (basket, plates and springs) from
Hinson Clutch
Components.
The group fabricated a specially made swing arm with the Toyota
logo machined into it. The rear shock included a custom reservoir
mount location to move it further away from the heat coming off of
the exhaust system. Clutch and front brake actuation were
accomplished using levers by ARC Levers, and Motion Pro cables.
Hammerhead Designs provided the shift lever and rear brake lever.
The brake rotors were custom pieces with the Toyota logo engraved
into them. Wheels from Spinergy Wheels utilizing Fiber Spoke
Technology completed the chassis modifications. Sprockets, bars,
and grips from Renthal finished the
operational modifications.
An on board data acquisition system from Pi Research was the final
touch to the project. This system was set up to provide real time
information on functions such as suspension travel, engine
temperature, and vehicle speed.
