Pro Circuit handles most of the engine work. Notice the
factory Honda shifter, which is made out of forged steel.
A well-performing Supercross bike needs a powerful front
brake. Windham’s oversize works Honda caliper does the trick.
racing setup that doesn’t take a Greek god to ride, but every year since 1995 he has been on factory equipment. His bikes are trick. And, as Kevin’s career has aged like fine wine, his bike setup has become more sophisticated and refined as well. The MXA wrecking crew has tested every conceivable type of motocross bike. From ragtag jalopies to pristine iron, we’ve seen it all. Kevin Windham’s Geico/Honda CRF450 might be defined by its rare and unobtainable works parts, but we see his steed in a different light from most. Kevin’s bike is the byproduct of hard work and dedication—the result of a real-world racer coming to terms with a machine that, for all its peccadilloes, has the potential to be the ultimate Supercross weapon. The Geico/Honda team is a very cool team. We enjoy chewing the fat with team manager Mike LaRocco and Geico/Honda’s technical director, Kristian Kibby. Which is why, when asked to give us Kevin Windham’s race bike, they readily acquiesced. SHOP TALK: BREAKING IT DOWN The MXA wrecking crew isn’t shy about expressing our disappointment in the 2011 Honda CRF450. In stock trim, the bike is unbalanced, the forks are soft, the handling is weird, and the power is decidedly mellow. For all our whining, though, the CRF450 does have a bright spot. With enough patience and money, the 2011 Honda CRF450 can be transformed into a serious racing machine. The Geico/Honda team has the experience, time and money to boost the CRF450’s performance enough to meet Windham’s expectations. The team focused on the key problem areas. Many of these changes were mandatory, as Supercross is extremely demanding on equipment. Transmission: The Honda factory supplies a works transmission for Windham. How does a works transmission differ from a stock tranny? For starters, the gear ratios are different. The gears are tightened up between ratios to avoid any unwanted gaps. The gears are polished for more accurate shifting, and the transmission is made of a higher grade of metal for greater durability. Kristian Kibby stated that the works transmission probably wouldn’t be necessary if the bike didn’t have to endure constant heavy loads while pounding through Supercross whoops. As for the drivetrain, K-Dub usually runs a 13/51 combination (stock is a 48-tooth rear sprocket). Engine: Every aspect of Windham’s Geico/Honda CRF450 engine is massaged in order to punch up the powerband. The Geico team relies heavily on Pro Circuit for their power equation. Need proof? Pro Circuit supplies the cylinder head, camshafts, valves, valve springs, valve seats, retainers, high-compression piston, radiator hoses and exhaust system. It’s only natural that a Pro Circuit Ti-4R titanium exhaust is paired with the engine (the muffler has been shortened for improved bottom-end power). Athena supplies the gaskets, while Renegade Racing SX4+ high-grade, AMA-legal racing fuel powers Windham’s bike. A Hinson clutch basket, inner hub, pressure plate and clutch springs are used (Kevin runs a six-spring clutch to prevent slipping). Honda provides Kevin with an unobtainium hydraulic clutch system. And, while the Geico/Honda team is sponsored by Moto Tassinari, at the time of this test, Windham’s bike didn’t
