THE FASTEST KTM WE EVER TESTED & ONLY $105,000 – KTM X-BOW RACE CAR By Daryl Ecklund Does the old saying, “With age comes a cage” hold true? I have contemplated this wisdom ever since my knees started to give me trouble. With each knee surgery (I’m currently at nine) I have thought more about diversifying my adrenaline input. Just like it’s good practice to spread your financial investments around so your exposure to any one asset class is limited, I felt that doing the same to my adrenaline account would be a sensible decision. What about switching sports completely? I couldn’t do that. After riding speedway, shifter karts, snow bikes, dirt trackers, downhill mountain bikes, ice racers, road bikes, supermoto and sport bikes, I know I could never find the same rush I get on a motocross track. But, I also know that if my fragile knees don’t last the test of time, getting into car racing will be my go-to sport—that is until my back lets go. Ever since the KTM X-Bow (pronounced Crossbow) came out in 2008, MXA wanted to get our hands on one. Why? For four reasons: (1) We wanted to explore the link between KTM’s car and motorcycle division. (2) It would make a really good story for a motorcycle magazine. We could title it, “The Fastest KTM We Ever Tested” or something equally mundane. (3) How hard could it be to get a test drive in a KTM X-Bow? After all, MXA has a good relationship with KTM America, and we have been to KTM’s headquarters in Mattighofen, Austria, many times, dating as far back as 1982. We figured they’d just hand one over. (4) Since the X-Bow was such a small but expensive project, we assumed that KTM would want more consumers, especially consumers who already owned a KTM product, to see what the X-Bow was all about. WE WERE ALWAYS SURPRISED WHEN WE WOULD ASK THE KTM MOTORCYCLE GUYS ABOUT THE X-BOW, AND THEY WOULD SAY THEY DIDN’T KNOW ANYTHING ABOUT IT. The X-Bow is assembled in Graz,, Austria, to city with a po[CENSORED]tion of 400,000 people, located 170 miles southwest of Mattighofen, which only has 6000 residents. We were always surprised when we would ask the KTM motorcycle guys about the X-Bow, and they would say they didn’t know anything about it. It turns out that they didn’t. The KTM motorcycle division and the KTM X-Bow division are completely separate of each other. No information or people are shared between the two KTM branches. The only traits they have in common are the KTM name and owner Stefan Pierer. Why? For starters, it is a car that has four wheels, not a motorcycle that has two. Everything is different. The physics, structure, aerodynamics, weight, powerplant, suspension, contact patch; the list goes on. Also, unlike Pierer’s motorcycle branch that relies on parts built in-house or from companies that are under the Stefan Pierer umbrella like WP, which builds Husky and KTM motorcycle frames and suspension, the KTM X-Bow is based on many outside companies working together. Once we found out about the KTM X-bow (pronounced Crossbow) we knew we had to get our hands on one. We found a bunch of them at the perfect place and we were off to put MXA’s orange helmet inside a race car. In building the X-Bow, KTM was like a conductor of a symphony. KTM brought together some of the most highly respected companies in the car racing industry to work together in unison to create the unique car. The Kiska design team was in charge of giving the X-Bow its KTM DNA, as the team has had their hands in designing many KTM models in the past. KTM Technologies and Dallara came together to develop the X-Bow as the world’s first production car with a full-carbon composite monocoque chassis. Dallara has had a near monopoly in the Formula 3 series for the last 25 years. The X-Bow’s carbon chassis was then outsourced to Wethje Carbon Composites in Austria. And last on the list is Audi, who brought to the table their 1984cc, turbocharged, inline, four-cylinder 2.0-liter engine. This is the same engine that is used on many of Audi’s production cars all the way up to the Audi S3—and the Volkswagen Golf. However, the Audi engine arrives in parts at the Graz production plant as many alterations are made to the engine to get it to produce 300 horsepower and 300 pound-feet of torque for the X-Bow R model. KTM offers other X-Bow models that pump out significantly more power. That is a powerful punch of power for a 1700-pound car. That may sound like a lot of weight in comparison to motorcycles, but to put it into perspective, the petite Mazda Miata MX-5 weighs 700 pounds more than the X-Bow and produces about half the pony power. WE WANTED TO TEST AN X-BOW, AND WE COULD SEE THAT GOING THROUGH OUR KTM MOTORCYCLE CONTACTS WASN’T GOING TO MAKE THAT HAPPEN. BUT, WE HAD AN ACE UP OUR SLEEVES. We love the technical aspects, but every conversation that we had with KTM about the X-Bow since 2008 always ended in a dead-end street. We wanted to test an X-Bow, and we could see that going through our KTM motorcycle contacts wasn’t going to make that happen. But, we had an ace up our sleeves. We turned inward to MXA endurance test rider Ernie Becker. Once a Pro Circuit Husqvarna rider, he became a successful sports car racer and now travels the world as a driving instructor for companies like Mercedes AMG and Lexus. He teaches Mercedes and Lexus owners how to drive their high-performance cars to their full potential. Ernie knows everyone in the American race car business through his racing, instructor gigs and is the rep for Metalor, an exclusive supplier of axles and hubs to Formula 1 and Indycar teams—and a competitor for Stefan Pierer’s Pankl company. One day at Glen Helen we told Ernie of our desire to drive a KTM X-Bow. He said that there was a fleet of KTM X-Bows that were used for a performance driving school, as well as a race series (organized by Simraceway), at the famous Sonoma Raceway (35 miles north of San Francisco). Ernie said that he knew the Simraceway people and he would try to make it happen. The rest is history.v Where you feet went to work, but only if your mind was engaged. Simraceway is a breeding ground for race car drivers. They offer many performance driving programs, including high-performance go-karts, racing schools, safe-driver training, LMP3 test days, as well as track days to take your own car around the 2.52-mile racetrack. Professional driver Matt Bell is the guy that runs the KTM X-Bow program, and he would be my instructor for a crash course on driving a race car. Ernie Becker took the time out of his busy schedule to come with Josh Mosiman and me to help guide us through our car indoctrination. The KTM X-Bow program at Sonoma Raceway has only been there for about a year. Before the X-Bows were used, Simraceway used Formula 3 cars. I asked Matt, “Why switch from an F3 race car to the KTM X-Bow?” Matt said, “The X-Bow is a much better starting point for learning how to drive a race car.” Simraceway is a breeding ground for race car drivers.

I asked Matt, “Why switch from an F3 race car to the KTM X-Bow?” Matt said, “The X-Bow is a much better starting point for learning how to drive a race car.” To make the driving experience even easier, an Audi DSG (direct shift gearbox), dual-clutch, 6-speed transmission is used in the KTM instead of a straight-forward manual transmission. Matt pointed out that most Americans don’t know how to drive a stick. America is not alone, KTM is having trouble with manual transmissions in China as well. The X-Bow does have paddle shifters, so you aren’t exactly driving a slush-box Hydramatic Oldsmobile around the track.The Simraceway KTM X-Bow Experience has a bevy of X-Bows ready to go out for for a real world experience on what can go wrong. The wheels were really turning after our crash classroom course on driving a race car. I learned that many aspects of racing motocross actually cross over to racing cars, but I wasn’t going to get ahead of myself. First, I had to actually get some real driving experience before I started acting like Lewis Hamilton. Matt started us out on learning the most important part of a racetrack—the corners. He set up one long, smooth, 180-degree corner on Sonoma’s skid pad. A skid pad is an area of flat pavement with nothing around it to hit. Matt didn’t exactly encourage me to spin out and make mistakes, but when I pushed it, at least I was in a safe place to learn what’s so bad about cross controlling in a turn.One of the key aspects of turning a race car is called trail braking. Braking hard initially before the corner creates the grip you need on the front tires to get you through the corner without over- or under-steering. When the cornering starts, the brakes slowly need to be released up to the apex of the corner. Trail braking creates the traction needed to turn at faster speeds. If you let off the brake too quick, or get on the throttle too early, the front tires could push or the rear end could swing around. What fascinated me was how late the apex was in the corners for race cars. I wanted to turn in too early and make the apex in the middle of the corner like I did on a dirt bike. But, those physics don’t work on the racetrack. Luckily, I was in radio contact with Matt, and he could tell me what I did wrong and how to improve it with each take. The car was all over the place, and I would often spin out fighting it. By getting the hard braking done early and trail braking through the corner, I eventually developed a smooth transition from brake to throttle. The straighter the car got, the more throttle you could give it. It was a constant balancing act between steering input, throttle and brakes. This single-corner exercise set me up for success throughout the entire day.
