TEN YEARS AGO TODAY: COMPLETE TEST OF THE 2013 KTM 350SXF

MXA was of the opinion that KTM had sandbagged the first 350SXF. If the 2011 KTM 350SXF had run as well as the 2013 350SXF, there would be a lot more 350cc bikes on the racetracks today

We rode the 2019 KTM 350SXF down at the private Chaney Ranch track. The 13,400 rpm engine is powerful yet, easy to ride. It is a bike that has the power of a 450, yet is nibble as a 250

WE RIDE CYLINDER WORKS’ KTM 365SXF BIG BORE

It’s no secret that we were disappointed with the 2011 KTM 350SXF. It wasn?t bad; it just wasn?t what we expected. We knew we could embrace the 350cc design philosophy if it were executed properly, because the Austrian company’s basic idea is sound: produce a mid-size, Open-class engine and tuck it into a lightweight 250cc chassis. The ideal 350cc motocross bike should produce around 50 horsepower and weigh 222 pounds. The resulting power-to-weight ratio would make it the ultimate motocross weapon. It s…

THIS MUCH WE KNOW! EXPLORING THE OPTIONS OF AFTERMARKET KTM BATTERIES

The KTM is the only motocross bike to come with a battery, because it is the only motocross bike to come with an electric starter. The upside of electric starting is that you just press the button and go. The downside is that the starter motor and battery add 5 pounds to the KTM’s overall weight. (Surprisingly, it still isn?t the heaviest bike in the class.) When you buy a new KTM, there is a 4.0-amp lead-acid battery in the bike. The stock Yuasa YTX4L-BS battery weighs 3.71 pounds (and the optional 5.0…

MXA’S 2014 KTM 350SXF MOTOCROSS TEST: THE LITTLE BIKE THAT COULD…IN THE RIGHT HANDS

FIRST AND FOREMOST, IS THE 2014 KTM 350SXF BETTER THAN THE 2011, 2012 AND 2013 350SXFs? A: Yes and no, but mostly no. That doesn?t mean that it’s a step backwards; it’s more of a step sideways. Q: HAS THE KTM 350SXF BEEN A SALES FAILURE? A: Far from it. The 350SXF has been a box-office hit from the moment it was introduced in 2011. It is KTM’s best-selling engine size, and the sales figures have been spectacular. Q: IF THE BIKE SELLS SO WELL, WHY HASN?T MXA EMBRACED IT? A: The initial 2011 KTM 350SXF wa…

2014 KTM 350SXF FIRST RIDE – MOTOCROSS ACTION’S MOST BEAUTIFUL BIKES

WE RIDE KTM FACTORY SERVICES’ 350SXF: IT IS A FACTORY BUILT ENGINE FOR NON-FACTORY RACERS

Have you ever picked up the phone and called Team Honda to see if they would hop-up your CRF450? No? Well, don?t. They won?t touch your engine?and they won?t accept any future phone calls from you. The same holds true for Team Kawasaki, Team Suzuki and, most certainly, the nonexistent Team Yamaha. But, amazingly, there is one factory team that will hop-up your engine to full-race, high-tech, factory specs. And while KTM isn?t going to pull 2012 Mechanic of the Year Carlos Rivera off Ryan Dungey’s bike t…

MXA TEAM TESTED: NIHILO CONCEPTS KTM FENDER ADAPTER

WHAT IS IT? There is nothing worse for the racer of an older model than to have the factory come out with a completely new look for the latest production bike. It was bad enough that you were racing an old bike, but now the new model makes it look even older. This happened to KTM owners when the 2013 models came with the all-new I-beam front fender. It was instantly recognizable, which made the lack of it even more obvious. The Nihilo Concepts fender kit allows the new fender to retrofit onto 2009??2012…

MXA TEAM TESTED: SHORAI KTM 250/350/450SXF LIGHTWEIGHT LITHIUM LFX BATTERY

WHAT IS IT?  The Shorai battery is 33 ounces lighter than the stock KTM Yuasa YTX battery. It uses lithium iron phosphate technology, instead of the traditional lead-acid construction. The recommended Shorai battery for a KTM motocross bi ke is the LFX14L2-BS12. It has more cranking power than the battery that MXA preferred, the LFX09L2-BS12. Why did we choose the LFX09L2-BS12. ? It was lighter and cheaper. However, even though we had no problems starting our test bikes with this battery, Shorai’s …

WE RIDE DUBACH RACING DEVELOPMENT’S KTM 350SXF

You?ve probably heard so much about the 2011-12 KTM 350SXF that your mind is on overload. By some pundits, the KTM 350SXF has been heralded as the second coming, and the ballyhoo was accompanied by a successful race debut in the hands of 450 World Champion Antonio Cairoli. Historically, aftermarket hop-up companies don?t put KTMs on their ?must-do? lists when it comes to making project bikes. Not so after 2011. Every company immediately started working on KTM 350SXF parts, pieces and paraphernalia. Why?…

MXA’S 2012 KTM 350SXF MOTOCROSS TEST: HAS THE 350 EXPERIMENT BEEN A SUCCESS? FIND OUT HERE

Q: FIRST AND FOREMOST, IS THE 2012 KTM 350SXF BETTER THAN THE 2011 350SXF? A: Yes. Most MXA test riders took a quick glance at the 2012 spec sheet and thought that it was the same-old, same-old. Not true. After their first race, every test rider felt that the 2012 KTM 350SXF was significantly better than the 2011 model. Q: IT IS CONTROVERSIAL, BUT IS THE 350SXF A SUCCESS? A: You bet. Regardless of what the keyboard commandos say, the American public has embraced KTM’s 350cc, mid-sized engine philosophy….

MOTOCROSS ACTION’S 2011 KTM 350SXF VERSUS KTM 450SXF SHOOTOUT:

There is a point in every motocross racer’s life when he believes in magic. No, not voodoo, psychic readings or David Copperfield. Motocrossers cling to the idea of the ?magic motorcycle??the machine that will change them from an also-ran into a front-runner; the bike that will make all their dreams come true; the single motorcycle that will change their lives. For obvious reasons, the idea of a ?magic motorcycle? is ludicrous, but there are plenty of stories about riders who got off a KX450F and onto a…

MXA PERFORMANCE GUIDE TO THE 2011 KTM 350SXF

WE RIDE ANDREW?SHORT’S FACTORY KTM 350SXF

Perhaps no bike in recent history has engendered as much controversy, idle chatter and uninformed speculation as the KTM 350SXF . The mid-sized Open class bike is really not a rare bird when viewed across the spectrum of motocross history. Many of the iconic Open class bikes raced over the years have been way below the maximum displacement. Included in this list of diminutive race bikes are the 360cc and 370cc machines used to great effect by Roger DeCoster during his heyday, the 360 Huskys of the Swedi…

To implement this, Don sourced a manufacturer in China to build exhaust pipes to his specifications. Even with shipping from China, Leib hoped to bring his Rocket Exhaust systems in for under $500.
