The wheels use works aluminum hubs with standard spokes and a finer thread into the nipples. Dunlop rubber wraps the wheels and to avoid getting a rear flat a mousse replaces the inner tube. The rear wheel sports a 230mm works rotor, a standard caliper with different pads, a different piston and all titanium hardware. The rear axle is made from special steel with stronger coatings. The front brake rotor is 280mm with a works caliper and works brake pads. The brake pedal is a one-off item with a titanium tip and the master cylinder is works from Japan. The footpegs are titanium as are the brackets that hold them. All the bolts on the bike are titanium except the top shock bolt, which is steel, and the bolts that hold the shrouds and seat (they are aluminum). The radiators on the #7 bike are wider than stock, pulling in more air and causing the shrouds to stick out a little more. The engine of a factory bike is top secret but we can tell you that the internals, like the crank, transmission, valves, cam and piston are all works, producing the big power Stewart demands. His mechanic told us Stewart runs a gear higher than other pros. The works oil pump covers hold more capacity and flows more oil to keep the temps down. To ensure the bike makes it through a moto without running out gas, a larger, custom carbon fiber tank replaces the stock aluminum unit. Works triple clamps hold the finest 49mm forks Showa has to offer and the works Showa shock operates through linkage that may look stock but it is altered from the factory. The Yoshimura exhaust system is specially built for the team and Stewart’s bike. The seat is also lower than stock, giving more room when standing.
