350 EXC-F 2013 - OVERVIEW
The power of a 450! The handling of a 250! With peak power of more than 45 hp, the KTM 350 EXC‑F is mixing it with the E2 class. Ultra-compact, with 57.5 mm stroke and 88 mm bore, and equipped with state-of-the-art electronic fuel injection, the engine offers a broad usable rev range. This delivers extremely efficient rideability and easily controllable traction on all terrain.
All EXC models are fitted with a PDS shock absorber and 48 mm USD front fork made by WP Suspension. New fork oil provides better sensitivity and more constant damping characteristics. The wide range of adjustability is KTM standard.
Following the proven KTM tradition, the frames are made of high-quality, lightweight chromemoly steel material in various profiles. They are specifically designed in conjunction with the PDS rear suspension system to provide precise cornering and high track stability.
SWING ARM »
All models feature a light-weight cast aluminium swing arm designed to fit the PDS shock absorber. The design guarantees high torsional rigidity and optimal flex characteristics, supporting the suspension.
The high-quality wheels with CNC machined hubs and high-strength 7050 aluminium GIANT rims are assembled in Mattighofen. The new spokes are covered with noble black coating which improves the corrosion resistance. Especially developed for KTM, are the new MAXXIS FIM tyres (80/100-21" MAXX CROSS 7311, 120/90-18" & 140/80-18" MAXX ENDURO 7314) which provide excellent traction, very precise cornering and top durability.
FUEL TANKS »
The slim 9.5 litre fuel tanks are made from lightweight translucent polyethylene. The 4-strokes are fitted with an additional micro-screen which is now located in the fuel line connector between the injector and tank for easier access. 13 litre tanks available for all models from the PowerParts collection, for the 2-strokes an additional 10 litre version.
The design of the airbox secures best protection for the TWIN AIR filter against dirt and maximum airflow for best performance. The ability to change the large filter quickly and without tools is the KTM standard.
EXHAUST SILENCER »
All bikes are fitted with lightweight aluminium silencers, which reduce the noise level to the FIM noise emission regulations (112 dB(A)).
The proven Brembo brake system is combined with lightweight wave discs for optimal brake performance. A further developed rear master cylinder features a new internal design providing less wear of the seal rubber and therefore longer durability.
To make a bodywork with super slim ergonomics and excellent contact points between rider and machine was a major development target. It provides unlimited freedom of movement. Newly designed graphics give a new appearance to the bikes.
All models are fitted with tapered high-strength aluminium handlebars made by Neken. For model year 2013 new 2-compound grips with KTM branding provide an excellent shape and improved grip.
ENGINE FEATURES »
The 350cc 4-stroke engine delivers a very broad and tractable power band and has very dynamic, but energy-saving engine characteristic. Its performance is powerful enough to beat any 450 in the E2 class. Ultra-compact and fitted with modern electronic fuel injection, the engine has a very wide usable speed range and very efficient rideability - the most user-friendly bike offering unparalleled riding fun.
CYLINDER HEAD »
The DOHC cylinder head is fitted with four ultra lightweight titanium valves (intake 36.3 mm, exhaust 29.1 mm) and lightweight finger followers with DLC coating, which allow a high rpm limit of 12,000 rpm.The cam timing is developed for smooth but powerful Enduro specific engine characteristics.
ENGINE CASES »
For MY2013 the casing is now produced in die-cast instead of sand-cast, so that the wall thickness could be reduced for weight saving (0.2 kg) without reducing strength. A special high-strength aluminium alloy guarantees high ductility for maximum safety against damage.
DDS CLUTCH »
The DDS (Damped Diaphragm Steel) one-piece clutch basket combined with the primary gear is made of high-strength steel. It guarantees unbeatable reliability and contributes to the narrow engine size due to its compact rivet-less design. Additionally, it allows the use of thin steel linings, which makes the whole clutch package compact. A diaphragm spring makes it possible to implement an additional rubber damping system, guaranteeing reliability for the transmission and good traction. The hydraulic clutch by Brembo in conjunction with the diaphragm spring guarantees a very light operation and good controllable modulation of the clutch.
BALANCER SHAFT »
For balancing the oscillating masses, the 350 EXC-F engine has a lateral balancer shaft, which also acts as a water pump and drive pinion gear for the camshaft. This solution delivers a very compact overall design of the engine.
