2012 KTM Motorcycle

When introduced in 2011, the KTM 350 EXC-F Factory was an immediate hit with the enduro crowd.

The bike was built upon the same principals of the 350 SX-F motocross bike – provide riders with the nimble handing of a 250 but with the power of a 450.

And for 2012, KTM returns with the 350 ECX-F, but with some major upgrades.

The new 350 EXC-F’s compact, state-of-the-art four-stroke engine excels with an extremely wide usable rev range and the performance of an engine with much greater displacement. A laterally positioned balancer shaft, which acts as the drive for both timing chain and water pump, eliminates the vibration typical of this model type.

In the cylinder head with two overhead camshafts, four titanium valves are actuated by extremely lightweight, carbon-coated cam levers. This sophisticated valve train, the ultra-light pistons and the new 350 EXC-F’s extremely short-stroke engine facilitate engine speeds of up to 13,000 rpm.

When designing the crankshaft on the new 350 EXC-F, KTM engineers focused on a reduction in the reciprocating weight and fine adjustment of the rotating masses. In this way, they managed to combine minimum vibration with an outstanding free-revving nature and optimum traction.

The new 350 EXC-F’s engine is equipped with two oil pumps. A pressure pump lubricates the engine, clutch as well as cools the ignition, while a suction pump draws oil from the crankcase, using it to lubricate the transmission. At the same time, this creates negative crankcase pressure, which provides an additional boost to engine performance.

The Keihin engine management system with electronic fuel injection ensures spontaneous responsiveness and maximum performance from the engine. Various engine characteristics can be activated with an optional map select switch.

The 350 EXC-F’s newly developed clutch, with a robust steel cage and transmission-friendly back-damping, makes use of a spring washer for the first time instead of the customary conical springs, hence substantially reducing the operating force. The hydraulic actuation mechanism from Brembo facilitates sensitive modulation of the clutch.

The six-gear transmission on the new 350 EXC-F has been designed especially to match the characteristics of the 350cc engine and meet the demands of enduro sport, excelling with its precise and easy shifting.

The new 350 EXC-F’s silencer with its large volume reduces noise levels to the stricter standards of the future.

The new 350 EXC-F is equipped with both a kickstarter and an electric starter. The drive for the electric starter is integrated into the generator cover instead of the engine case, so the bike can be converted into a pure kickstarter simply by replacing the generator cover.

The new 350 EXC-F’s lightweight frame made from high-quality chrome-molybdenum steel is distinguished by an extremely high level of lateral stiffness. It is also excellent at absorbing jolts introduced by the suspension system, whereby the playful handling and comfort of the 350 EXC-F have been further optimized.
TELESCOPIC FORK

The new 350 EXC-F is equipped with the latest WP upside-down fork which offers a wide range of both compression and rebound adjustment. The sensitive responsiveness and outstanding damping of the open-cartridge fork with 48 mm (1.89 in) outer tubes are a perfect complement for the 350 EXC-F’s playful handling and precision.
WHEELS

New black Giant rims with CNC machined hubs, black spokes and silver spoke nipples and Metzler Six Days Extreme DOT front and rear tires.

The new 350 EXC-F’s bodywork with the very slim seat and radiator shrouds, plus excellent contact points, perfect the bike’s ergonomics, making handling even simpler and more precise. The long rear fender protects the rider very effectively from flying back tire roost.
