The 2009 season will go down as being one of the most exciting championship battles of the last decade. Chad Reed and James Stewart went toe-to-toe all the way to Las Vegas for the Supercross crown, while more riders won AMA 450 Nationals in a single season than in recent memory. Chad Reed came up a few points short in Supercross, but he outlasted all-comers in the AMA 450 National Championship. It was a great year of racing; made all the more interesting by Chad’s last-second decision to race the outdoor Nationals.

It is surprising in many ways that Chad even found a ride for the 2009 season. How so? When last year’s 450 National series was finishing up in August of 2008, Chad Reed was still searching for a ride. He didn’t think it would be a problem?since he was the reigning 2008 Supercross champion. He was wrong! After he turned down L&M Yamaha’s reported $2 mil offer, he discovered that no one else wanted to play (or pay). It wasn’t until rather late in the game that Makita/Suzuki, with the help of Rockstar Energy drink, signed Reed to a one-year deal (at a considerable pay cut). Chad became the biggest high-profile name since Ricky Carmichael to ride under the Suzuki banner, and he also became the points leader in the young Supercross series after a run-in with James Stewart at Round 1. Throughout the season, the two swapped paint and the points lead several times before James Stewart finally sealed the deal in Las Vegas.

No one likes to finish second in the Supercross championship (unless it’s 1995 and your name happens to be privateer Larry Ward). But instead of brooding about the loss for the next seven months, Chad Reed moved on to greener pastures by agreeing to race the AMA 450 Nationals. Reed turned the lemons of Superceross into the lemonaide of motocross.

The ever inquisitive MXA wrecking crew called Roger DeCoster and inquired about the possibility of testing Chad’s RM-Z450. It didn’t take long to hear a positive response, and in short order we found ourselves on Chad’s bike at Suzuki’s private test track.

SHOP TALK: DISCUSSING THE COMPONENTS
 

There’s an involved process in testing any motocross bike, but it becomes especially difficult when analyzing a factory bike. From the outside looking in, most people would jump at the opportunity to ride a works bike. After all, you are given intimate time with a one-of-a-kind machine and the opportunity to ride it for as long as you please. However, there is an exorbitant amount of information that needs to be covered in order to fully understand the bike.

The MXA wrecking crew had to play a cat-and-mouse game with the Makita/Suzuki mechanics when dissecting Chad Reed’s RM-Z450. We searched for every kernel of information that we could gleen, while the Suzuki mechanics did their best to give no quarter. Why? Loose lips sink ships, and the last people factory teams want to tell their million-dollar secrets to are MXA’s test riders. Roger DeCoster couldn’t make it to our test, which was unfortunate, because Roger is very honest and forthcoming. He knows what’s secret and what’s not. The mechanics were unsure of what was verboten to talk about and what wasn’t, so in an effort to keep their jobs, they were very vague. It wasn’t MXA’s first rodeo, though, and it didn’t take us long to start getting real answers to our questions. Case in point, when we mentioned the engine modifications, we received a sarcastic answer stating that Reed’s powerplant was stock. Even those members of the MXA wrecking crew who are still wet behind the ears saw through that cloud of donkey dung.

Most of the specifications on Chad Reed’s factory RM-Z450 were easy to spot. The frame, swingarm and engine cases were stock, because the AMA rule book states that these parts must remain production. Also on the stock list were the aluminum gas tank (at least in terms of the minimum fuel capacity), radiators, radiator cap, engine cylinder and plastic. With the help of a few key aftermarket companies, the stock 2009 RM-Z450 was transformed from an also-ran into the perfect weapon for Reed to win on. Pro Circuit not only handled the exhaust duties (Ti-4R full race system), but also reinforced the rear brake (brake snake) and helped the Suzuki keep the front end down on starts (holeshot device). Pro Taper provided full-waffle, hard-density grips and low-bend handlebars. Tag Metals took care of the gearing (13/51 for Supercross tracks and 13/49 for outdoor tracks). D.I.D. put power to the ground with the chain. Twin Air handled the air filter, while NGK spark plugs, CP Pistons, Hinson clutches, Excel rims, Bridgestone tires, One Industries graphics and Maxima oil handled the rest. Thanks to the wildly popular Maxima SC-1 spray, Reed’s bike looked sharp and shiny.
 

A factory bike is supposed to have all the expensive bells and whistles that aren’t for sale, and Reed’s RM-Z450 didn’t disappoint. Every square inch of the Suzuki was studied, massaged and made better. No stone was left unturned, evidenced by the extensive list of works parts.            

Suspension: At the top of the list was the Showa works suspension. With superior parts to the stock offerings, larger components and better actuation and flow, the Showa units were the bread and butter of Reed’s RM-Z450 package. Not even Ryan Dungey or Nico Izzi were allowed to use the full-works forks that Chad had for Supercross, because AMA rules don’t allow 250 Supercross riders to use suspension that’s not available to the public. Ryan Dungey and Nico Izzi raced with Showa A Kit suspension, while Chad and Mike Alessi had the good stuff.

Components: Also on the works parts list was the integrated hot-start lever/choke, titanium footpegs (although they were the same width as stock), brake rotors, front brake caliper, 20mm offset triple clamps, bar mounts, transmission, carbon fiber engine spacers, titanium pivot bolt, engine head, valves, camshaft, crank, ignition, hubs, axles, linkage, levers, skid plate, shifter, and titanium nuts and bolts (the heads on the bolts were drilled out for even greater weight savings).

What wasn’t on Chad Reed’s bike that we expected to see? The parts are few and far between, but mostly we were surprised to discover that in its Supercross mode, Reed’s RM-Z450 lacked a radiator catch tank or external shock reservoir. These two parts aren’t imperative for improved performance, especially in Supercross, but we were surprised that Suzuki didn’t have any interest in utilizing these (sometimes) advantageous parts.

TEST RIDE: HOLD ON AND PRAY

Chad Reed isn’t normal in any sense of the word. He is lightning fast, adapts quickly to track changes, never gives up and isn’t from this continent. Chad is, however, normal in stature and weight. The 27-year-old stands at 5’11” and tips the scale at 160 pounds. His average stature excited every single MXA test rider. Why? The average test rider on the MXA wrecking crew stands about 5’11” and weighs about 180 pounds. You’re probably wondering why we would be so elated that Reed weighs 20 pounds less than most MXA test riders, but if you have ever ridden with works bike suspension, then you know that it doesn’t move without considerable effort. The only way an average motocross racer can get the forks and shock to budge is by being extremely fast or having a bulbaceous body profile. We figured that our heavier weight would force the suspension to move. We were right.

Reed’s Showa works suspension was nice, which is shocking to say. It is rare that the suspension of a top pro is actually usable. In fact, when we tested James Stewart’s L&M YZ450F (available on this web site) we could barely get an inch of travel out of his forks. Reed’s works units were remarkably manageable?especially compared to Stewart’s. On a motocross track, it was very stiff, but for Supercross the suspension felt metered and balanced. Lighter riders found that the front end was slightly stiffer than the rear, which caused riders to jump nose high. After one MXA test rider nearly looped out over a double, a quick shift in body positioning towards the front of the cockpit remedied the problem.

EVERY TEST RIDER RAVED ABOUT THE DYNAMIC ENGINE PERFORMANCE. AT LOW SPEED, THE RM-Z450 WAS MANAGEABLE, BUT AS THE RIDER TWISTED THE THROTTLE, HE WAS REWARDED WITH A POWERBAND THAT BEGGED TO BE PUSHED TO THE LIMITS.

When asked to describe Reed’s engine profile, words like “powerful,” “smooth” and “aggressive” were commonplace. Typically, when discerning the characteristics of an engine, it’s rare to hear words like smooth and aggressive in the same sentence. Then we learned that Chad Reed’s RM-Z450 engine had two distinct personalities. Off the bottom, the engine was smooth and powerful, but once in the midrange, the bipolar powerplant became very responsive and aggressive. Every test rider raved about the dynamic engine performance. At low speed, the RM-Z450 was manageable, but as the rider twisted the throttle, he was rewarded with a powerband that begged to be pushed to the limits.

The MXA wrecking crew has learned quite a few things about Chad Reed simply by riding his bike. For example, we know that Reed isn’t very kind to his clutch. The clue? His overly stiff clutch springs are built to take abuse. He also has a slightly schizophrenic personality. How so? His clutch and brake lever aren’t even. The cast clutch lever is higher than the billet front brake lever. At first, the dissimilar levers felt awkward, but they weren’t even noticeable after a few laps of riding. Chad is also very set in his ways. We figured this out the first time we applied his brakes. They are very powerful, which was made readily apparent by his trash-can-lid sized front brake rotor. The 280mm works rotor looked like it belonged on a GSX-R750.    

CONCLUSION: WHAT DO WE REALLY THINK?

Of all the factory bikes that we have tested in the last few years, Chad Reed’s RM-Z450 stands out. This isn’t a surprise to us, because we have tested a lot of Suzuki works bikes in the past?and we have always been impressed by them (and to this day, Travis Pastrana’s works Suzuki RM250 ranks as one of the greatest bikes we have ever thrown a leg over). Reed’s engine was powerful, yet manageable. The suspension actually compressed under a heavy load, and the overall bike setup was comfortable. Chad Reed didn’t win the Supercross championship, but he did win the Lucas Oil 450 National Championship.

As for that pay cut he took at the start of the season, he more made up for it with $3,000,000 in win bonuses from Suzuki and a creative insurance policy of his own.
