the 350 sure does feel great in the woods. especially now after I put the 12/52 gearing on. the 12 sure beats out the 13 tooth.
some more vids from hancock

The 350 EXC-F is the ultimate enduro when it comes to optimum rideability and maximum enduro performance. Thanks to its compact, powerful DOHC engine, its low weight and perfectly tuned chassis, this machine overcomes all problems presented by the terrain with incredible ease. And thanks to its playful handling, it is always at an advantage when the going gets really tough. Whether professional or beginner, this benefits the rider all the more, the longer the track is. Maximum fun factor guaranteed!
Highlights
  • Engine: The 350cc 4-stroke engine with a state-of-the-art electronic fuel injection offers a very wide power band and is distinguished by a dynamic but fatigue proof power delivery. At over 45hp of maximum power, the 350 EXC-F is strong enough to beat any 450.
  • Engine Case: The engine case production process was already converted from sand casting to die casting in the previous model year in order to reduce the wall thickness and save weight. In MY 2014, the optimized gasket for the new water-pump cover guarantees absolute reliability even in the toughest of conditions.
  • Cooling System: The proven integrated KTM cooling system routes the coolant from the cylinder head through the frame triangle directly to the aluminum radiators made by WP. The EXC models are fitted with a fan system as standard, whose thermo switch has been optimized for 2014.
  • Valve Train: The crankshaft drives a laterally positioned intermediate shaft that also acts as a balancer shaft, water pump drive and timing chain drive for the two camshafts. A hydraulic chain adjuster ensures reliable chain tension and consequently extremely precise valve timing.
  • Balancer Shaft: In order to balance the mass-forces, the 350 EXC-F engine has a counter balancer shaft on the right side, doubling as a water pump drive and cam chain drive wheel. This solution is a major contribution to the extremely compact engine layout.
  • Crankshaft: Compared with the 350 SX-F, the 350 EXC-F is equipped with a heavier crankshaft to generate more gyrating mass for more uniform power development and better traction. Similarly to last season's KTM SX-F models, it is equipped with a plain bearing in the lower conrod eye. The previous needle bearing is replaced with two press-fit bearing shells that run directly on the crankshaft's crank pin. This design enhances the durability of the engine, thereby enabling an extension to the service intervals for the crankshaft.
  • Cylinder Head: 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 perfectly 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.
  • 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 addition, 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.
  • Oil Circuit: The 350 EXC-F engine is equipped with two oil pumps. A pressure pump provides reliable lubrication for the crankshaft, piston, counter balancer shaft and valve train. In addition, it ensures the cooling of the ignition and lubrication of the clutch. A scavenger pump draws oil from the crankcase to lubricate the transmission. This also creates a small vacuum inside the crankcase which increases engine performance.
  • Air Box: The redesigned airbox offers maximum protection of the air filter against soiling while ensuring maximum airflow for top performance. The new airbox covers are produced in a 2-component process and with new inmold graphics. The left cover's mount and fitment have been improved further to allow an even quicker change of the Twin Air filter which is held more securely with an optimized latch. The filter can still be changed without using tools. In addition, two extra flaps on the cover allow securing it with bolts if desired.
  • Fuel Tank: All fuel tanks are made of lightweight polythene. The 4-stroke models are fitted with fuel pumps and pressure regulators. The release mechanism of the bayonet filler cap has been optimized so the cap can be opened quicker and easier.
  • Starter: The engine is equipped with a kickstarter as well as an electric starter as standard. Well protected behind the cylinder, the electric starter is connected to the freewheel on the ignition rotor via the starter drive in the ignition cover.
  • Transmission: The 6-speed gear box is specially matched to the power delivery of the 350cc engine and any kind of enduro riding. It is distinguished by easy and precise shifting.
  • DDS Clutch: 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.
  • Frame: The modern and lightweight frame design made of high-strength chromoly steel sections combines maximum longitudinal stiffness with optimum torsional rigidity. It guarantees easy handling and precise cornering, but also outstanding stability. In 2014, the frame of the 4-stroke weighs even less thanks to thinner walled down tubes. In addition, the braces that connect the cylinder head were optimized. This means all new frames not only have a striking new color but also set the clear benchmark with respect to weight and stability.
  • Triple Clamps: The lower triple clamp has been redesigned for optimum accommodation of the new front fender. Thanks to its new contour and mounting with two front and two bottom bolts, the new fender has a lot more stability.
  • Swingarm: Designed using the latest in calculation and simulation software, the design and wall thickness of the cast aluminum swingarm have been optimized for minimum weight at optimum stiffness and precisely defined flexibility. For 2014, the engineers have revised the chain guide to increase reliability while lowering the weight.
  • Suspension/Damping: The first rate WP Suspension elements have been further improved for 2014. Specially designed for enduro riding and in some models with an optimized tuning, they ensure maximum traction and plenty of comfort. Of course, compression and rebound damping can be adjusted to the track conditions and the rider's preferences with a twist of the wrist - the rear monoshock has separate high and low speed adjustments.
  • Wheels: The wheels feature CNC-machined hubs, high-end Excel rims and black coated spokes with lightweight aluminum nipples, allowing the highest levels of stability to be achieved while keeping weight to a minimum. The fitted Maxxis enduro tires have been specially developed for KTM and excel with perfect traction and outstanding performance.
  • Bodywork: Shrouds, airbox cover, front fender, headlight fairing and the headlight have all been restyled for 2014. The KTM designer's focus was to achieve complete ergonomic harmony between rider and bike for a more stable ride and effortless movement on the bike. Adding to the improvements is a high-quality seat foam core to maximize comfort and durability. With the new front fender, the designers omitted ribbing on the inside to reduce mud and dirt buildup while increasing rigidity over the previous component by 50 percent.
  • Graphics: New, classy graphics with clear lines visually underscore the exacting standards of what KTM deems a true, cutting-edge offroad bike.
  • Seat: The seat has an improved foam core that ensures even higher stability of the padding.
  • Handlebar: All EXC models are fitted with the super strong, tapered Neken handlebar made of high tensile strength aluminum alloy. The proven standard KTM mount allows fixing the handlebar in four different positions. 2014 sees the introduction of newly-developed hand guards made of 2-component polymer for more effective hand protection.

The fan - Yes, although I still do not have one on my '12 model. The 14/52 gearing seems a bit low. My '12 came with 14/45 which was ridiculously tall. The swap to 13/48 feels just about right. 14/52 is a bit lower than that. Gearing is no big deal anyway, as most folks swap it out to suite there needs anyway.
To me, the bigger improvements are the plain bearing in the lower con rod eye, the modified compression release system, and the water pump gasket. I wonder if these upgrades will fit in my '12 model, when the time comes.
I had also read about "more powerful" starter motors, but I did not see it listed here.
My bike starts OK, but sometimes stops when it bumps up against the compression. It usually only does this once - and not every time.
The "optimized" DDS clutch statement is also intriguing. I wonder how it is different...

I think the starter motor is fine, it's the battery that needs more cranking amps.

I agree the plain bearing crank is a huge upgrade. 13/48 and 14/52 are almost the same ratio.

Anyone running a Pirelli Scorpion xcmh rear 120/100-18? I'm curious how tall that is compared to the stock Maxxis I have on there now. My Maxis appears to be 36.5 inches high at 14 psi.

Near Tahoe N.F. in N. CA.

Get the Radiator Fan!
I thought I wouldn't need one but if yer cow trailing, hill climbing or bustin' yer ass exploring/building some some new singletrack like this during the heat of the summer- you'll need the fan. I just added mine. (13/48 gearing)
It cycles off pretty quick, I added 'Ice' coolant as well.

Pirelli Rear Tire-yes a bit taller than the stock Maxis, tippy toes for me at 5'6" tall.
I've just about wore out my first Pirelli MT43 4.00x18 rear tire (+/-1500miles). Good compromise in dry conditions. Now that it's well worn, it's for shit sliding in loose stuff down hill (steep).

If you get into a loose rocky hill climb with the Pirelli, drop the pressure down to near 12 psi, or you'll be bouncing all over the place.

Balance your tires.

The stock Maxis knobbies worked great but I went through them like butter in no time at all.

Yes, there was a guy posting in KTMworld that indicated the same thing - that his 2014 model did *not* have a fan as stock equipment. Are the 2014's even out yet in the US?

Easy solution. Dirt Tricks makes several fan kits that work on these bikes. I've got the simple manual switch model.

They make thermostatically controlled models also. Their mounting kit is really cool (and KoolAid Orange to boot!)
