The 350 XCF-W is the ultimate machine when optimum rideability and maximum enduro performance are called for. Thanks to its compact, powerful DOHC engine, its low weight and its perfectly tuned suspension, this machine masters each and every tough spot in cross-country riding with ease and poise. And thanks to its playful handling, it always holds the advantage when the going gets tough. The longer the distance, the more the rider benefits from this, pros and beginners alike. Maximum fun factor guaranteed.
Features May Include:
The 350 XCF-W engine is equipped with a 196 W generator with integrated starter freewheel. The generator provides sufficient energy for fuel injection, lighting and other electrical loads. Compared to the 350 SX-F, the oil-cooled rotor has a larger diameter with a large flywheel mass and requires a larger ignition cover.
Compared with the 350 SX-F, the 350 XCF-W has a a heavier crankshaft in order to achieve a more even power delivery and better traction through the greater gyrating mass. Like last season's KTM SX-F models, it now has a plain big end bearing.The previous needle bearing is replaced by two force-fitted bearing shells that run directly on the crank pin. The necessary oil feed for this bearing is ensured by the engine's pressure lubrication. This design increases the engine's long-term durability, allowing to lengthen the crankshaft service interval - a customer benefit with respect to time, effort and cost.
ENGINE MANAGEMENT SYSTEM (EMS)
The Engine Management System (EMS) by Keihin with electronic fuel injection and 42mm throttle body ensures a spontaneous response and maximum engine performance. With an optional map-select switch from the KTM PowerParts program, EMS allows selecting different engine characteristics. In additon, the optional User-Setting Tool allows to readout engine data with a laptop and change the ignition and injection mappings with a few mouse clicks.
The DOHC cylinder head contains four ultra-lightweight titanium valves (intake 36.3mm, exhaust 29.1mm), which allow extremely high engine speed levels of up to 12,000 rpm in combination with very small, DLC-coated followers that weigh only 8g. The camshaft timings are pefectly tuned for performance in the enduro specific low rev range. In 2014, new valve spring retainers provide even more durability under the most extreme conditions, while a revised auto-decompression mechanism optimizes starting performance.
Optimized for 2014, the single-piece basket of the DDS (Damped Diaphragm Steel) clutch is machined from solid high-tensile steel in one piece together with the primary drive gear. This process guarantees unbeatable reliability and contributes to the narrow engine width due to its compact rivet-less design. Additionally, this construction allows the use of thin steel linings which also contribute to the compact clutch dimensions. The diaphragm spring makes it possible to implement an additional rubber damping system inside the clutch hub, guaranteeing reliability for the transmission and good traction. In addition, a stronger inner hub further increases stability. Finally, the hydraulic clutch mechanism by Brembo in conjunction with the diaphragm spring guarantees a very light operation and good controllable modulation of the clutch.
