Putting The Super In Supermoto

DR-Z400SM supermoto bike is a no boubt adout it. Lightweight, highly maneuverable and blessed long-travel suspension, it makes the daily commute a blast. snarled up? Duck down side street, hop over the cut through the back alley and pop out a over, where traffic is

Blacktop, dirt or any surface in no problem.

The 324-pound (wet) is a great entry-level bike, especially for someone coming the dirt side of things. Its seat height sounds but the suspension sags a few inches the rider’s weight, so it’s lower. Of course, that suspension can be a handicap if you flog it at the supermoto/kart track like we

And no matter where you ride it, the single makes a paltry horsepower and 26.2 pound-feet of at the rear wheel, which is a way of saying it’s s-l-o-w. drag-strip testing for our street-legal comparison (Swinging Singles, July 2006), the DR-Z that most humbling of an na in the 0-100-mph category.

Fortunately, it take much to make the (or black) Suzuki a better-performing The SM may only have hit the market in but it’s based on the dual-sport that debuted in 2000, so a wealth of tuning knowledge. Schwantz even won national-level races on one.

Granted, his factory-backed bike was to the tune of tens of thousands of whereas we hoped to spend $1500 upgrading ours.

it comes to tapping into the conscious, there’s no better than the Internet. And when it to four-… dirtbikes, there’s no site than www.thumpertalk.com. we found near-universal approval of the Stage 2 kit ($64.89 from along with a 3×3-inch cut in the top of the airbox.

Since we planned to run an exhaust, we set up the stock Mikuni CV carb with the richer main jet, the Dynojet with the clip in the second and the fuel mixture screw 3.5 out. In this era of electronic installing the jet kit was fun-therapeutic even-or at it was once we managed to remove the Phillips-head screws securing the bowl. Do yourself a favor and them with Allen

Being street guys, was only one place to go for a pipe: RD. Aiming to keep things we opted for the RS3 Comp-Series slip-on in steel ($375 from Installation was a snap, and subsequent runs showed 2 additional and 2 more lbs.-ft. of torque.

That doesn’t sound much, but it represents gains of percent! More impressive was the with peak torque 200 rpm lower at 5900 and peak arriving 600 rpm higher at 8100. the formerly lean engine now up quicker, throttle response was and the bike didn’t feel gears as often.

The slip-on shaved off a few pounds compared to the muffler and gave the exhaust a nice-albeit too loud-bark. Should you to be neighborly, order a TEC (Tunable End kit.

With the motor now stronger, we turned our attention to the The SM is already beefed-up from with an aluminum swingarm, adjustable shock and the stiffer fork from an RM250 Yet even so, its spring rates are too for aggressive use. So we took our to Race Tech, where installed Gold Valves and rear plus a set of stiffer fork springs and a 5.7-kg-mm spring.

Total cost: The difference was remarkable, as the bike a lot less with the rider in the and snapped up into stoppies of bottoming under braking. control was also much which we appreciated while it into corners or negotiating whoops.

To keep the DR-Z’s price at an $6199, Suzuki cut a few corners and a few el cheapo parts. Most is the steel handlebar, which is to bend the first time you the bike. Surprisingly, the ’07 SM with an oversized aluminum Fatbar at no extra cost, so the handlebar is as easy as ordering from your dealer.

To the conversion, you’ll need the bar, bar ends, upper and clamps, the nuts and bolts to them together and a key switch. really only need the key mounting bracket, but it isn’t separately.) Total price for the is a whopping $430.23, but you can’t OE quality.

The other new ’07 worth retrofitting are the axle These prevent damage not to the axles and axle nuts, but to the fork legs and swingarm-not to the asphalt, which is a bone of with some kart-track Because the right rear gets in the way of the axle nut’s pin, you’ll also the ’07 locknut. Installation maybe a minute per and total is $83.50.

Alternatively, you could purchase sliders designed to retain the pin from companies such as (www.rhinomoto.com).

One other cost-saving we noted in our comparison was handguards, protect not only your but also your levers in quarters (i.e. while or riding at the supermoto track). The Rider guys had a set of yellow M2 Spine Handguards lying the office ($44.95 from so on they went. These fine for general riding, but offer the crash protection we have liked.

A better bet have been the $109.95 Billet Handguards or $129.95 Racer Kit.

The last we ordered before pausing to add up we’d spent were brake lines and pads from www.galferusa.com), which doing the aforementioned brake and stoppies that much That brought our total to $1989.85, which meant blown our budget, but it was all money spent.

If we had to do it again, we’d saved a hundred or so bucks by the Renthal Fatbar from the instead of from Suzuki, or that amount by substituting a set of new 71/48-inch aluminum bars, would have worked the stock clamps. The money we would have gone a way toward purchasing guards to the DR-Z’s fragile engine (deburring the back of the shift is a good start) and radiators.

We also might have around on eBay and bought a kit that lets the midpipe to the frame instead of the right-side bracket. A set of supermoto race also would have a natural. And if money were no a slipper clutch.

But if we were to get that serious, we’d pop for a proper super-moto racebike.

in the real world, with our picked clean, we turned our to those things we could by expending nothing more elbow grease. Unbolting the rubber inserts from the footpegs gave us better Stripping the seat of its passenger strap let us slide fore and aft

We know we wear a helmet and use unleaded so don’t need to be reminded on a basis.

Our low-buck DR-Z project out so well that after photos of Online Editor Loy riding it for this story, Wing took the bike for a and promptly worked a deal to buy it. He delivery just before and later sent us an e-mail: I hit malls for some last-minute and turned an absolute nightmare situation into a riot! I was on a high the next day and put about 120 on it in the Santa Monica Mountains.
