KTM Reveals All-New 2016 SX bikes

KTM North America has revealed its 2016 lineup of SX-F motocross models, and as expected the bikes are very similar to the 2015 Factory Edition models we started to see last December. Compared to the 2015 SX-F line, the bikes offer completely new engines, chassis, and suspension, with drastic increases in power, reductions in weight, and improvements in handling. David Pingree got to ride the 2015 450 Factory Edition and 250 Factory Edition bikes recently and was impressed by both. We expect the regular 2016 SX-F models to offer similar traits.

All three four-stroke SX-F models—the 250, 350, and 450—boast new, lighter, and more compact engines wrapped in new frames. A steeper head angle and shorter wheelbase promises improved cornering, but optimized frame rigidity and geometry are supposed to keep stability in tact. The bikes also feature new lithium-ion batteries that weigh just 1.1 pounds, similar to the aftermarket units everyone would usually fit to their bikes. KTM claims a weight of 220 pounds for the 205SX-F (about five pounds less than the 2015 SX-F), 223 pounds for the 350 SX-F (about seven pounds less than the 2015 SX-F) and 224 pounds for the 450SX-F (over 10 pounds lighter than the 2015 SX-F).

KTM continues to pour big development work into its two-stroke line as well, as both the 125 SX and 150 SX feature all-new engines which are lighter and more powerful, and fit them into chassis with similar improvements to the new four-strokes. Each bike weighs just 197 pounds! The two-stroke 250 SX continues with small refinements. 

Here are official photos and information from KTM on each bike. 

450 SX-F

If asked for maximum power there is no other way but the KTM 450 SX-F. This model has proven itself in championships around the world over the years. Thanks to its compact SOHC engine that delivers explosive but controllable power, it is the weapon of choice for the US KTM Factory Team’s successful 2013 and 2014 AMA Lucas Oil Pro Motocross Championships and 2015 Monster Energy AMA Supercross, an FIM World Championship. For 2016 the 450 SX-F presents itself with an all new chassis and engine, reducing overall weight 10.7 pounds making the new model even easier to ride. All the while, setting a new benchmark of 62hp in terms of peak power. The 2016 KTM 450 SX-F is the lightest, fastest 450 MX bike on the track, consider the game changed.

350 SX-F 

With the new generation of the 350 SX-F the success story can go on. The dominance with which this machine has won one world championship title after the other is unparalleled. In his first year as KTM factory rider, Antonio “Tony” Cairoli already managed to win the 2010 MX1 World Championship with just 350cc. Ever since, the Red Bull athlete from Sicily dominated the competition in his class at will. The results are five consecutive World Championship titles, won with ease in the top tier of MXGP by Cairoli and the KTM 350 SX-F. Almost as much power as a 450, but the agility of a 250—the basic idea is easily summarized. A concept that has been successful from the start.

For 2016 everything is new: chassis, suspension, bodywork and a more powerful fuel injected engine. The all-new 350 SX-F is even faster also due to an overall weight reduction of 6.8 pounds. An essential point in the new construction was to create even more compact dimensions in order to achieve a more effective centralization of mass for improved rideability.

This combination of low weight, playful agility and a high-revving engine will be again the right machine for Cairoli to defend his title in the new season, since the 350 SX-F provides the ideal characteristics for pros and amateurs alike.
