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…

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…

MXA’S 2013 KTM 350SXF MOTOCROSS TEST: THE LITTLE BIKE THAT COULDN’T, BUT NOW IT CAN

FIRST AND FOREMOST, IS THE 2013 KTM 350SXF BETTER THAN THE 2011 AND 2012 350SXF? A: Awesomely so! Q: HOW DOES THE 2013 KTM 350SXF COMPARE TO THE PREVIOUS TWO KTM 350SXF EDITIONS? A: We have always been of the opinion that KTM had been sandbagging on the first generation of the 350SXF. The first edition in 2011 was overly rich and not especially fast. Making matters worse was a top-end-only powerband that pumped out a meager 46.94 horsepower at a skyscraper 12,200 rpm. Consumers expected a mid-size 450, …
