2012 KTM 350 EXC-F Six Days

Posted on by 0

The 350 EXC-F was unleashed and is ready to race in the famous enduro competition the "International Six Days Enduro". This competition is a tough test for both the bike and its rider as is translated in thousands off road kilometers and over 40 hours spent in the saddle.

Needles to say, that both the rider and bike need a very tough character to be able to finish this race successfully. Thereby, KTM’s technicians gave their best to arm the 350 EXC-F Six Days with all it needs to be able to endure harsh riding conditions.

To help it stand out from the crowd, the 350 EXC-F Six Days received an orange powder-coated frame and a newly developed clutch with a robust steel cage and transmission-friendly back-damping. The bike also features a hydraulic actuation mechanism from Brembo which facilitates sensitive modulation of the clutch.

Power comes from a rugged 350cc engine paired with a specially tuned six-gear transmission.

Press Release

Engine

KTM 350 EXC-F Six Days
  • 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 elaborate valve train, the ultra-light pistons and the new 350 EXC-F’s extremely short-stroke engine facilitate speeds of up to 13,000 1/min.
  • The balancer shaft not only eliminates vibration, but also acts as an intermediate shaft for the valve train and as the drive for the water pump. This intelligent multi-functionality makes a key contribution to the compactness and low weight of the new 350 EXC-F’s engine.
  • When designing the crankshaft on the new 350 EXC-F, KTM engineers focussed 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 and clutch and cools the ignition, while a suction pump draws oil from the crankcase, using it to lubricate the transmission. At the same time, negative pressure arises in the casing, which provides an additional boost to engine power.
  • 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.

New Frame and Suspension

KTM 350 EXC-F Six Days
  • 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 optimised.
  • The new 350 EXC-F’s lightweight cast aluminium swingarm accommodates the WP shock absorber almost centrally, in order to load the swing arms more evenly. The PDS shock absorber with adjustable rebound and high/low-speed compression damping works with high progression, in spite of the direct linking.
  • The new 350 EXC-F is equipped with the latest WP upside-down fork with wide adjustment ranges. The sensitive responsiveness and outstanding damping of the open-cartridge fork with 48 mm outer tubes are a perfect complement for the 350 EXC-F’s playful handling and precision.
  • Practically unbeatable in terms of weight and stability, the new wheels have CNC-machined hubs, new black-anodised rims from Giant, black zinc/nickel-coated spokes and ultra-light aluminium nipples. They reduce the unsprung and gyroscopic masses, hence boosting the playful handling of the new 350 EXC-F.

Electric Starter

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.

Bodywork

The new 350 EXC-F’s bodywork with the very slim seat and spoiler lines, plus excellent contact points, perfects the bike’s ergonomics, making handling even simpler and more precise. The long rear fender protects the rider very effectively from swirled up stones.

Six Days Equipment

KTM 350 EXC-F Six Days
  • Map select switch on the handlebars for selecting different engine management mappings
  • Camel SXS seat for improved long-distance comfort
  • Engine guard made of high-strength plastic for protecting engine case and frame down tubes
  • Radiator fan for optimising temperature control under extreme loads
  • CNC-machined, orange-anodised triple clamps for high-precision clamping of the fork tubes in favour of optimum sliding of the telescopic fork
  • Knock-out wheel spindle for easier removal of the front wheel
  • Full brake disc at the rear for improved heat resistance and therefore reduced pad wear
  • Rear brake disc protector for protecting the brake disc from mechanical damage
  • Quick-change brake pad securing bolts at the rear for quicker changing of brake pads without tools
  • Aluminium rear sprocket with riveted-on steel ring gear for a combination of reduced weight and increased durability
  • Wheels with black-anodised, extremely robust Giant rims and spokes with a high-quality, black tin-nickel coating
  • The same design as the KTM factory bikes thanks to Six Days graphics, orange powder-coated frame, orange anodised triple clamps, orange anodised handlebars and anthracite anodised silencer
