  Q: FIRST AND FOREMOST, IS THE 2014 KTM 125SX BETTER THAN THE 2013 KTM 125SX? A: The easy answer is no. Most of the changes that KTM made to the 2014 125SX were chassis, durability or cosmetic changes. Q: WHAT DOES A 2014 KTM 125SX COST? A: The retail price of the KTM 125SX […]

MXA’S 2014 KTM 150SX MOTOCROSS TEST: THIS BIKE IS DESIGNED TO BE RIDDEN BY A SPECIAL KIND OF RIDER


Q: FIRST AND FOREMOST, IS THE 2014 KTM 150SX BETTER THAN THE 2013 KTM 150SX? A: The easy answer is no. Most of the changes that KTM made to the 2014 150SX either didn?t bring about significant improvement or were pushes at best. Q: WHAT CHANGES DID KTM MAKE TO THE 2014 150SX ENGINE? A: There were only three changes to the 150 powerplant for 2014. (1) Jetting. After years of on-the-edge jetting, KTM fiddled with the brass one more time. (2) Black box. The ignition mapping has less advance off the bottom …

MXA TWO-STROKE SHOOTOUT! THE 2013 KTM 125SX VERSUS THE 2013 KTM 150SX


Q: WHAT’S BETTER A 125SX OR A 150SX? A: The MXA wrecking crew can promise one thing with this shootout?KTM is going to win. But, we aren?t sure that there is an outright winner because each bike is designed and built for a different reason, consumer and purpose. Who you are makes a bigger difference than the performance of either bike. 2013 KTM 125SX: At 34.66 horsepower, the KTM 125S X is a classic shriek machine. Q: WHY DOES KTM MAKE BOTH A 125 AND A 150? A: That is a question that KTM asks itself fiv…

MXA MID-SIZED SHOOTOUT: WHICH IS BEST? A 125 TWO-STROKE, 250 FOUR-STROKE OR 250 TWO-STROKE


  Not every rider is alike. There are riders who like the snap of a 250cc two-stroke, those who prefer to wring the guts out of a wide-open 125cc tiddler, and a third group that craves the abundant vibes of a 250cc four-stroke. The MXA wrecking crew decided to round up all three of these bikes and compare them head to head. Now, you might be wondering why we didn?t include a 450cc four-stroke in the comparison. The answer is simple: very few riders are trying to decided between a 450cc bike and a s…

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’S 2012 KTM 125SX MOTOCROSS TEST: AN OLD FRIEND RETURNS


Q: FIRST AND FOREMOST, IS THE 2012 KTM 125SX BETTER THAN THE 2011 125SX? A: We don?t know, because KTM stopped importing the 125SX to the USA four years ago. Still, we know that KTM has made quantum leaps forward since 2008. Q: WHY IS THE KTM 125SX BACK? A: When KTM debuted the original KTM 144SX in 2008, its sales quickly eclipsed those of the 2008 125SX. KTM took one look at the sales numbers and decided to cut their expenses by only importing the more popular 144SX, which was soon to be called the 15…

TWO-STROKE TEST: 2012 KTM 150SX IS ALL ABOUT HAVING FUN ON A DIRT BIKE


Q: IS THE KTM 150SX STILL THE ONLY KTM TIDDLER SOLD IN THE USA? A: No, the KTM 125SX motocross bike is back for 2012. Three years ago, KTM made the 125SX obsolete by introducing an identical motocross bike with more power?the 144SX. After a quick glance at sales figures for the 144SX versus the 125SX, KTM decided to shelve the 125SX and only import the 144SX, which would later morph into the 150SX. For 2012, KTM decided that the market for a true 125cc two-stroke was big enough to put it back into the l…

2011 KTM 150SX MOTOCROSS TEST: PERHAPS THE BEST BIKE FOR RIDERS LOOKING TO MAXIMIZE THE FUN OF RACING


Q: FIRST AND FOREMOST, IS THE 2011 KTM 150SX BETTER THAN THE 2010 KTM 150SX? A: Yes. KTM continues to refine its two-strokes, in spite of what the other manufacturers do. The traditional KTM practice of including the 150SX in all the common changes and then throwing in a few model-specific refinements still applies?although 150-specific updates are minimal this year.   Q: WHAT WERE THE KTM 150SX UPDATES FOR 2011? A: There were eight refinements. (1) Frame. Last year, KTM made the head angle half a …

FRIDAY’S USED MOTOCROSS BIKE GUIDE: HOW TO SETUP YOUR 2010 KTM 150SX TWO-STROKE:


This is the 2010 KTM 150SX the way the MXA test crew raced it. As a rule, we don?t go for exotic or expensive mods, but if push comes to shove, we will seek competent help (no matter how much it costs). Use MXA ‘s mods as a guide.   Clutch. Take some time to look closely at your KTM 150SX clutch pack. There are four aluminum drive plates and two steel plates. Make sure that the two steel plates are in the center of the pack (not on the ends). As you would expect, the aluminum plates wear quicker th…

MXA MOTOCROSS 125 SHOOTOUT: 2011 KTM 150SX VS. 2011 YAMAHA YZ125 TWO-STROKE


2011 KTM 1250SX. Both the KTM 150SX and Yamaha YZ125 originated from the classic two-stroke gene pool, but thanks to gene splicing, borrowed technology and constant revisions, both machines have evolved into the fulfillment of the two-stroke promise. And, unlike most bikes that are compared to each other, these two bikes have grown more apart over the last few years?they are not ?clonemobiles,? and it is possible that they aren?t even justly compared. The $6299 KTM 150SX and $6250 YZ125 may owe their ge…

2012 NEW MOTOCROSS BIKE BUYERS GUIDE: THE 2012 KTM TWO-STROKES; THE 125SX, 150SX & 250SX


KTM takes two-strokes seriously and it is showing in their sales charts?KTM sells more two-strokes that some Japanese brands sell of all of their motocross bikes. So you can’t fault the Austrians for investing more money into the 2012 KTM two-strokes: (1) The KTM 125SX will return to the KTM line-up. It had been dropped several years ago when the 150SX was introduced. Now, KTM believes that the revitalized interest will fuel an increase in 125cc sales. (2) KTM’s 150SX is an iconic machine that has found…

REAL TESTS! 2010 MXA RACE TEST OF THE KTM 150SX:


Valuable lessons: It is a shame that most young riders will never experience the joy of racing a full-size two-stroke. The KTM 150SX teaches throttle control, energy management and how to race while giggling in joy. Q: FIRST AND FOREMOST, IS THE 2010 KTM 150SX BETTER THAN THE 2009 150SX? A: Yes, but not because it is a completely new machine or because the engineers found a spare five horsepower lying around. It’s better because KTM has always made yearly updates?not always big improvements, but changes…

2009 KTM 150SX AND KTM 250SX TWO STROKES:


   You might consider this a test of rare, exotic and unusual machinery. Don?t let the fact that these are production bikes fool you into thinking that they aren?t extremely unique. They are. In a world where two-strokes are now considered pass‚, the fact that KTM builds a production-line, big-bore 125 and is one of only two of the major brands still producing 250cc two-strokes makes these two machines very special.    KTM is the king of niche marketing. KTM has always taken advantag…

2009 KTMs


What’s new on the 2009 KTM 450SXF? First and foremost, the 2009 450SXF almost got a five-speed transmission, but at the last second KTM decided to stay with the four speed box. The black anodized triple clamps feature 18mm or 20mm adjustable offset to hold the 48mm WP forks. As for the forks, they offer new bottoming cones, revised valving, less unsprung weight and improvised flex characteristics. Thankfully, all full-size KTM race bikes will come with white number plate backgrounds that are large enoug…

2008 RACE TEST:KTM 125SX VS KTM 144SX


125 144 If the MXA wrecking crew ran Yamaha, the only other Big Five manufacturer to produce a 125cc two-stroke in 2008, we?d order the R&D department to turn it into a YZ150 for 2009. Face it; the classic model of the 125cc class is broken. No longer competitive on the National circuit, abandoned by consumers, and suffering a torque gap to the new breed of 250cc four-strokes, the venerable 125 will soon reach room temperature unless the manufacturers find a new business model. Thankfully, AMA amate…

2008 KTM Intro: Are You Ready For Electric Start Two-Strokes?


When KTM rider Cyril Despres recently won his third victory in the Red Bull Romaniacs Hard Enduro he became the first rider to win on the new 300 EXC-E (which is KTM’s new electric-start 300cc two-stroke). According to Despres, “As riders, we are always concerned about the bikes having any extra weight and I was a bit unsure before the race about the addition of the battery and the electronic starter for that reason. But I have to say it was very helpful in many situations and it is definitely an advant…

MXA’S SECRET JETTING SPECS, 2003 And Back


We can’t tell you how to jet your bike. It’s a big world out there (and we don’t know you all that well). However, we can tell you what jetting we run in the MXA test fleet. Take into account that we race in a Mediterranean climate, near sea level, within sight of palm trees and never far from a Double Latte. We also run fresh 92-octane gas, work on our bikes every week, clean the filters, change pistons and rings regularly, are alert to pinging and haven’t changed oil brands in over a decade. This is t…
