When the average motohead cruises the pits at a Supercross, he or she sees a sweet works bike constrained by a so-called production rule. A mechanic might see cubic hours of labor, but an accountant would see a huge pile of money. And since there is both time and money in a works bike, you might wonder if the poorly-tuned economy has eroded the quality of these finest examples of moto machinery. We'll be honest: A few of the impressive rigs, some faces we've come to expect and long-time supporting sponsors were missing. But at the pointy end of racing, when it comes to the machinery intended for guys with an honest shot at a win, the bikes are still glorious examples of moto excess. But you can bet that performance spending is carefully scrutinized to ensure bang for the buck. Of the three podium finishers in the 450 class at Anaheim 1, the most obvious example was Kevin Windham and Factory Connection racing with "production" suspension. Trust us, when FC finishes with it, you wouldn't tell it from "works" by riding it. Ryan Dungey's Suzuki RM-Z450 looked as trick as ever, but Suzuki started with essentially the same bike as Reed's '09, and Mike Gosselaar is still working on it-talk about efficient R&D.; James Stewart's 2010 YZ450F was looking a little more stock than we expected his bikes to look, but there aren't many aftermarket parts ready for that bike, and Yamaha-whether it has an in-house factory team or not-likes its number one bikes to look pretty stock. As you might expect, we took a very close look at the bikes, and we are passing along the goods. Check out the top SX machinery in the world right here, right now.Honda reportedly had the trickest ignition in 2008. Riders pushed a button on the start line, and a specialized power setting was engaged for the start. As soon as the rider down-shifted, the map reverted to race mode. In race mode the ignition changed radically to kill engine braking and make the specific power each rider preferred. In '09 these electronics weren't ready to be combined with the EFI, but now Honda has the '08 features plus two map choices on the fly.Honda was running these wild-looking fork caps. The team has been mute about what the additional adjusters are, and claims that two are air bleed screws. The odd shape looks like a weight-reducing move to us. Notice the slot and pinch bolt in the steering stem portion of the top triple clamp? That is for Davi Millsaps only. With his size and aggressive style he twists the front end without the additional safeguards.Millsaps and Andrew Short run engines with approximately the same internal specs, but with very different exhaust pipes. Milsaps runs this short pipe with a chamber on the header for more hit. Short, ironically, runs a longer pipe for smoother, longer power delivery. Naturally they do run different ergonomic set-ups to accommodate their differing heights.New for 2010 was a hydraulic clutch system. The rules allow this on a modified stock case. You can see the welds where the slave portion was added. Having the juice clutch must be for consistent, automatic adjustment, since the pull doesn't seem a lot easier than a stock cable-operated unit.
