KTM DUKE
CYCLE WORLD TEST
RUDE, CRUDE AND SOCIALLY UNACCEPTABLE...IN OTHER WORDS, WAY DAMN COOL
DO NOT BUY THIS MOTORCYCLE. DON'T EVEN THINK ABOUT IT. Steer clear. Move on before it's too late. Turn the page. Nothing good can come of it. KTM's Duke, the first pure streetbike the tiny Austrian firm has sold in the U.S., is a diabolic device that will land you in hot water quicker than Senator Bob Packwood at a panty raid. This bike is 609cc worth of stonkin' Single that lives for three things and three things only: 1) wheelies, 2) stoppies and 3) rorty romps through the gearbox. The meek may inherit the Earth, but they won’t be riding around on KTM Dukes.
You can thank ABC Sports for the Duke. It’s a direct descendent of the hybrid racebikes used in the early-’80s made-for-TV “Superbikers” shows. Run on a half-dirt, half-asphalt course, these were mainly bigbore two-stroke motocrossers with shortened suspensions, roadracing front brakes and flat-track tires. Several years after the show went off the air. Superbikers racing was rediscovered by the Europeans-in particular the French, apparently unsatiated by old Jerry Lewis movies and “Baywatch” reruns, and casting about for another American art form to adopt. “Supermotard” was born, soon to grow into a series with a season-ending finale that now attracts big-name racers from all over the world (see Race Watch, CW, February, 1994).
All of this did not go unnoticed by KTM back home in Mattighofen at the foot of the Bavarian Alps. When the European show circuit rolled around in 1993, there on the KTM Sportmotorcycle AG stand, among the MXers and the enduros, w'as a curious-looking concept bike w'ith supermotard styling. Reaction from the press and public was so strong that KTM put the bike on the books for 1994; now a limited number of Dukes have been brought to the U.S.
Not much has changed from that 1993 concept bike. The Duke’s chassis is based heavily on the company’s off-road frame, gussied up with a polished aluminum swingarm. The fuel tank is the same 3-gallon vessel used on the dirtbikes, molded in black plastic this time. Sheathing the sides of the tank and sweeping forward around the twin radiators are plastic shrouds finished in a very tasty gray-on-black checkerboard pattern meant to resemble carbon-fiber. Sidepanels and rear fender were also pulled from the dirtbike molds, set off by dark metallic-gray paint and more faux-fiber. A graceful pair of passenger grabrails bolts to the rear fender, and a nicely done subfender/chainguard mates to the swingarm.
Leading this assemblage down the road is the Duke’s most radical derivation from its dirtbike roots. The Dutch-made 40mm WP Roma fork is roadrace-quality stuff, mated to a similarly serious Brembo four-piston caliper. The latter, plumbed with a plastic-wrapped steel line, is capable of brutally severe stoppage-witness coverboy D. Canet standing the Duke on its nose like a trained circus seal.
Topping the whole affair is an organically styled fairing that incorporates twin headlights, tachometer, speedometer, ignition switeh/fork lock and a small cluster of warning lights. The speedo and tach faces are particularly touchyfeely, with numbers done in a lilting, script type-style. Also, the tach doesn't read in anything as clinical as rpm; it records “beats per minute.” Disregard the bold “620cc” emblazoned on the fairing’s sides, by the way, truth-in-labeling being a somewhat loose concept in Austria—the Duke’s 101 x 76mm bore and stroke works out to an actual 609cc.
Akront supplies the Duke’s jaunty wire-spoked rims, 17inchers, wide enough-at 3.5 inches front, 4.5 rear-to qualify for sportbike duty. Spooned onto these are limited-production Pirelli MT60 radiais that, true to the supermotard theme, resemble dirt-track tires. These proved surprisingly grippy, the downside being accelerated wear, especially at the rear, and the fact that the MTs will most likely need to be special-ordered come replacement time.
The end result of all this cross-bred styling is a motorcycle with an undeniable flair-part dirt-slinger, part roadster, with a touch of Bat-bike thrown in for good measure, all put together with a level of fit-and-finish that rivals anything being built today.
That degree of refinement does not, however, extend to the Duke’s engine. It was built for enduro and motocross competition, so it’s fairly uncivilized for a street motor, which gives the bike a certain hooligan charm, but doesn’t make it very suitable for around-town plonking or steady-state highway cruising. The Duke is happiest when it’s pulling hard through its slick-shifting five-speed gearbox, revs zinging between 5000 and 8000 rpm ( red 1 i ne is 8500), cutting loose with the splendid sound that only a lightly muffled, high-revving Single can gcnerate-think of a BSA Gold Star on crystal-meth.
Fair enough; KTM makes no pretense that the Duke is anything other than “an unashamed street fighter...not for sissies...designed for the experienced enthusiast...built with true connoisseurs in mind,” to quote the company literature.
In KTM's view, electric start has no place on such a he-man's machine, so the Duke has to be kicked to life. The good news is that the LC4 motor is one of the easiest-starting big-bore Singles ever. Retract the sidestand, making sure the double-spring-loaded apparatus-mandated by some well-meaning Euro-crat, no doubt-doesn't thwack you in the shin and draw blood. Swing the left-side kick lever out. Then, standing off to the side of the bike, kick with your right boot. Aided by an automatic compression release, the engine will almost always light off on the first or second kick-unless, of course, friends and family have gathered `round to admire your vaunted kickstarting prowess, in which case all hope is lost....
CWs test Duke, the first California-spec model, had its 49-state Dell Orto carb yanked in favor of a cleaner-running 38mm Edelbrock Qwik Silver II mixer. A derivative of the old Leetron carb, this uses a flat slide and a single needle—no jets. Officials of both companies admit that the Qwik Silver underwent-let’s be kind here-an accelerated development program for use on the KTM. As such, the Duke’s carburetion was less than ideal, with a hiccup or two in the powerband and the occasional dreaded flame-out at stoplights. Apparently, the hot tip is to fit a 40mm Qwik Silver, but don’t let the California Air Resources Board know where y a heard that.
Other than the carb niggles, the Duke worked as anticipated, sling-shotting around corners and annihilating apexes the way any all-up fully gassed 340-pound street-tracker with near-limitless ground clearance should. If the KTM pays any penalties for its dirtbike upbringing, it’s in a relatively high center of gravity; two byproducts of this being a seat height of 35 inches and a slight reluctance to be slammed hard-left, hard-right (or vice versa) during on-the1 imit cornering.
KÍM will import 80 Duke 620s this year, priced at a super-stiff $7900. It’s a motorcycle for people who understand the allure of a performance Single, who like to be different, who want a bike with balls. And if you hurry, there might just be a few left that are unspoken for.
But, remember, we warned you. E2
EDITORS' NOTES
NICE TO SEE A LITTLE COMPANY LIKE KTM trying something new in the Singles class, even if the end result ain't for everybody.
Heck, even I'm a little confused by the Duke. What is it, what's it made for? Its mission statement may be ambiguous, but 1 confess that every time I get on this bike, it talks to me-in bad ways. The throttle says, "Twist me, go on!" The front-brake lever shouts, "Grab me and pucker, now!" At least that's my excuse when I take off with a spinning rear wheel, ride it into a wheelie then bring things to an immediate halt with a stoppie of epic propor tions. Not exactly the kind of behavior one expects from a responsible editor at America's Leading Motorcycle Magazine, I admit-but, hey, a lot of fun.
Look, the Duke is about as practical as a screen door in a submarine. No worries, though; I'm sure there will be plen tyof Thumper fans, more fond of slicks than knobs, visiting KTM dealers this year.

You REMEMBER THE PRODUCED-FOR television "Superbikers" shows of the mid-1980s. Played out on a mix of pavement and dirt, they were hyped as a showdown between the top roadracers, dirt-trackers and motocrossers.
GP-star Eddie Lawson won the `84 event on a Yamaha YZ490-based hybrid, besting MXers Danny "Magoo" Chandler and Broc Glover. Lawsons YZ sported numerous changes, including an oversize 031 front disc, an RD350 caliper and 19-inch wheels, among other things. Editor-in-Chief Edwards road the bike at the Austin Aquafest roadraces four years later and says it was one of the most thrilling motorcycles he's thrown a leg over.
Fashioned from the same mold, KTM's Duke is a Superbiker for the `90s. Beautiflilly finished, it's light and narrow with a front brake that's strong enough to stop a bull elephant. Given the choice, I'd opt for the Dell'Orto equipped 49-state model, however.

LORD, GET THIS THING AWAY FROM ME! If you're one of the few, the brave, the 80 that will take possession of a Duke this year, good luck. All I'm doing is putting my license in jeopardy and pissing off the neighbors.
The phrase "Ride hard or stay home" was coined for this KTM. It's amazing how much entertainment 42 horsepow er can provide when it's hooked up to a motorcycle that weighs 323 pounds dry, has gumball tires and an absolute anchor for a front brake. No, the Duke won't be running down any ZX-lls in a straight line-wasn't meant to. Besides, 176 mph may be a nice place to visit, but I wouldn't want live there. In the real world of sub-80-mph speeds that most of us inhabit, especially if twists and turns are thrown into the equation, the Duke is damn-near untouchable.
I could never own the Duke as an only bike, but as Sunday-morning shot in the arm, it's just about dead-on perfect.
