MC Project: Buell Tribute Bike

Mad Props!

With great torque comes great back-torque, so Bilansky also installed an STM slipper clutch from Erik Buell Racing. On the stocker, heavy engine braking complicates aggressive corner entries with unwanted rear-wheel chatter. The Italian-made STM kit replaces the original pressure plate with a progressive-engagement, forced-lubrication slipper mechanism that absorbs this back-torque and eliminates wheel hop. The effect is dramatic, allowing you to drop multiple gears at a time and step the back end out as smoothly as Chris Carr on a mile dirt-track. The slipper mechanism also protects from unintentional overrevving that can result in bent valves-a not-uncommon danger for these low-revving pushrod twins.

With the powertrain wrapped up, we turned our attention to chassis upgrades. Dumpster diving in the defunct Buell race department netted some unobtanium exotica in the form of a fully adjustable Öhlins fork originally intended for the ultra-rare XBRR Formula Xtreme racer. A one-off billet bracket holds a single race-spec, eight-piston Nissin brake caliper biting on Buell's patented Zero-Torsion-Loading (ZTL) front rotor, attached with Erik Buell Racing's new rotor-mounting kit for improved heat dissipation. It's worth noting that, even after two track days, this is the only ZTL-equipped Buell we've tested that hasn't hot-spotted or warped its rotor. An adjustable LSL steering damper from Buell specialists American Sport Bike tucks under the lower triple to keep the front end calm when the inevitable wheelies arise.

The stock swingarm and belt final drive were likewise replaced with Erik Buell Racing's chain-drive swingarm conversion, shedding pounds and enabling easy gear changes. Covered with machining marks and capped with hard-anodized, endurance racing-style, quick-change axle adjusters, the EBR race-kit swingarm is pure hardware porn, and it simplifies tire changes, too. A Vortex Racing aluminum sprocket and gold-anodized RK #520 X-ring chain complete the final drive.

Connecting the race swingarm to the stock XB frame proved challenging. Our donor bike was a Lightning Long extended-wheelbase version, and there were no aftermarket shocks available. Our best (and possibly only) option was a custom unit from David Behrend at Fast Bike Industries. A former Erion Racing crew member and Öhlins USA technical support manager, Behrend hand-built an Öhlins shock from parts and tuned it specifically for our intended use. FBI's typical custom shock pricing is around $125 more than an off-the-shelf unit, making this service a great value for anyone needing a shock for a custom or vintage bike.

After the chassis was dialed-in, styling was all that remained. The upright, high-bar Buell already felt like a dirtbike from the saddle, so we decided to give it a flat-track/supermoto look. Simplifying matters was the fact that Buell's Super TT bodywork-complete with number plates, fork guards, hand guards and front fender beak-bolt right onto the existing Lightning frame. Custom, XB12-themed vinyl graphics from motocross/supermoto masters DeCal Works, sub-surface printed on durable, 19-mil high-gloss vinyl, complete the competition-inspired look.

A taller, flatter Super TT saddle capped off the supermoto look and feel, along with a cross-braced Renthal Streetfighter handlebar that's slightly lower and wider than the stock bar for a more aggressive riding stance. A license plate relocator from American Sport Bike, perfectly matched in Hammertone silver, deletes the original cheese grater extended fender for a tighter look. Dunlop's D616 sport radials-designed to resemble racing rain tires and offered as original equipment on first-year Buell XB12X Ulysses-look exactly right on our sumo-styled ride, and the thick, cool-running tread delivers long wear and good grip in all conditions, even at the racetrack.

The racetrack was where we debuted our Buell tribute bike, in front of Erik himself and a few hundred fans attending last summer's Buell Homecoming at Blackhawk Farms. Though he declined a ride, Buell spent some time inspecting the bike in every detail before giving it his ultimate endorsement: "Out on the back roads," he said, "that thing is just going to be a blast!"

He was absolutely right. In the twisty alphabet-soup of letter-named highways criss-crossing southern Wisconsin, our big-bore supermoto has no equal. It feels like a 92-horse BMX bike, and encourages the same sort of jackassery you practiced on your bicycle as a kid. It's ridiculously easy to wheelie-the short wheelbase and high bar make it feel like you could just yank the front wheel up manual-style. And with so much torque so low down in the rev range, this Super TT stands right up on the gas. That smooth slipper clutch and mega-strong front stopper make it just as easy to get the rear Dunlop hacked out and howling whenever the throttle is closed, and it's all you can do not to jump every neighborhood curb-though the upgraded suspension could easily handle the hit. Like any Öhlins-equipped bike, this one feels unflappable and ultra-responsive over even the roughest pavement. Even better, the excessive fore-and-aft pitching that plagued the high-riding, short-wheelbase stock Lightning has been completely eradicated.

Buell was onto something with his original sportfighter XBs, and our hot-rodded Super TT is the best example we've ridden yet. Improved with suspension that's somehow firmer yet more compliant, and outfitted with technological assists like the slipper clutch, steering damper and flawless fuel injection that smooth over any rough edges, it's hard to put a wheel wrong. Our tribute bike gives new meaning to Buell's old "own the corners" tagline, and is endlessly entertaining in the ever-changing backroad milieu. The unique blend of power and simplicity makes it a supremely engaging bike to ride, guaranteed to spot-weld a smile to your face. We can't think of a better tribute to the man behind the Buell brand.
