PIC: The Ultimate Motocross bike?

Automotive giant Toyota teamed up with Joe Gibbs Racing to create this stunning one-off concept motocross bike for the 2009 SEMA Show in Las Vegas (see below for more pictures, click on them to enlarge).

The partnership, in conjunction with the Joe Gibbs Toyota NASCAR group, saw more than 100 man hours invested into the project, with modifications and accessories provided by 17 contributors.

The project started out using a 2009 Yamaha YZ450F as the base platform to work from.

The group utilised a specially lightened and polished frame, and installed carbon fibre 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 fibre 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 optimised the bike's balance point.

Further induction modifications included a fan-driven forced air intake system with fuel injection. A Carillo rod coupled with a JE 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 fibre 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 utilising 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.

A speedometer? You can tell you don't know anything about racing. It's a Pi System data system which will do everything including telling you the exhaust temp at the pipe, the head temp, lap times, rpm's, etc etc. Try educating yourself before making such a foolish statement.
