According to Pro Circuit mechanic Wayne Lumgair, the average guy can buy most of the items found on Tyla Rattray’s KX450F. Whether you buy into that or not, chances are you would have to take out a second mortgage on your house to build an exact replica of the Rattray’s Kawi.
For sure, Rattray’s bike is trick, and complete with the coolest things Pro Circuit has to offer; as well as a few “factory” items that are unobtainable for the average guy, like the factory hubs, for instance.
Of course, the usual PC fare can be found all over, including PC triple clamps, a full titanium exhaust system, PC pistons, rod, titanium valves, valve springs, and cams. All of the clutch components except for the springs are Hinson, including the hub, basket and pressure plates. Meanwhile, the clutch springs are PC.
The forks are the new Showa triple air, which the team switched to just before the outdoor series started. Kawasaki and Yoshimura Suzuki are the other two teams running these.
The wheels are special factory items from Kawasaki Japan, as are the hubs and spokes. The brakes are factory as well, and include a magnesium Nissin front brake caliper with high-friction brake pads.
Even the clutch arm is special. It’s hand-made in Japan for the team. Villopoto runs a similar one.
Rattray (and the rest of the Pro Circui team) also runs a GET ignition, which enables the team to gather data after each race or practice session.
Like most of the teams in the paddocks, PC runs a Moto Tassinari Air4orce intake system. Other aftermarket items include a Twin Air filter, DP rear brake pads, a LightSpeed skid plate, ARC composite levers, and an RK chain.
