New 2017 KTM 250SX $7,198
The new KTM 250 SX with its all-new engine has one of the best power-to-weight ratios in the world of dirt, forming the ultimate weapon against more complex 4-stroke rivals. With the grunt to devour all sorts of tracks and terrains, and a lightweight chassis keen to skim the surface, this masterpiece of KTM’s R&D and Motorsport departments is born to lead the next pack of winners that prefer premix.Features may include:
The engine of the 250 SX has been known and respected for being the most powerful 2-stroke engine in its class. But we thought the segment could use an extra push and a solid statement: 2-strokes have a future at KTM. Their outstanding power-to-weight ratio, low cost and simplicity see to that. Putting our money where our mouth is, we gave the 250 SX engine an all new architecture with a new shaft arrangement for better mass centralization, a new cylinder with a twin-valve controlled power valve, a new counter balancer for less engine vibrations, a 5-speed transmission and a hydraulically operated DDS clutch. This compact fireball truly outshines the competition with absolutely ripping performance and is the right choice for lovers of premix.
The newly developed cylinder of the 250 SX - with a bore of 66.4mm - has all-new ports and is fitted with an overhauled power valve system. This system features a sophisticated mechanism for the lateral support exhaust ports, providing smooth and controllable power on tap. Furthermore, it’s possible to change the bike’s mood in seconds thanks to two supplied powervalve springs. Limitless settings for different tracks and preferences are up for grabs. Throw everything you have at it; new water jackets in the cylinder and head will take care of excess heat and reworked lateral cylinder head brackets allow a more efficient fixation of the engine to the frame via lightweight head stays. Yes, this is a serious piece of kit.
- ENGINE CASES
These all-new die-cast engine cases feature a 8mm higher clutch shaft and a 27mm higher crankshaft, resulting in better mass centralization. Which is nice if you care about sweet rideability. In addition, it allows the implementation of a counter balance shaft. So your ride will be as relaxed as it is rapid. Plus, your new favorite engine will keep looking as fresh as the day you bought it: redesigned engine covers feature a smart surface structure in order to reduce the wear caused by the rider’s boots.
The 250 SX employs the KTM-developed DDS clutch (damped diaphragm steel) with a wear-free steel basket and extremely heat resistant clutch plates. This clever design employs a diaphragm spring instead of the usual coil springs, which makes for a considerably easier clutch action. A diaphragm spring also leaves sufficient space for a damping system to be integrated into the clutch hub. The goal was traction, yes, but durability as well. On top of that, it is fitted with a lighter basket, a reworked inner hub and a pressure plate providing better oil supply and unsurpassed cooling. Of course, light operation and telepathic amounts of control are what make this particular clutch, a hydraulic Brembo clutch.
- COUNTER BALANCE SHAFT
Say goodbye to numb feet and hands. The new engine design allows the implementation of a lateral counter balance shaft in order to reduce the vibration level drastically (50% lower level on handlebar and foot pegs). You know what that means: less fatigue at the end of the moto so you can push when it really counts.
