HANDLING OF A 250
RAME
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.
SWINGARM, PDS
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.
TELESCOPIC FORK
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
(1.89 in) outer tubes are a perfect complement for the 350 EXC-F's playful
handling and precision.
WHEELS
Practically unbeatable in terms of
weight and stability, the wheels have CNC-machined hubs, Excel rims,
zinc/nickel-coated spokes and aluminium nipples. They reduce the unsprung and
gyroscopic masses, hence boosting the playful handling of the new 350 EXC-F.
PERFORMANCE OF A 450
ENGINE
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.
CYLINDER HEAD
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.
BALANCER SHAFT
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.
CRANKSHAFT
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.
LUBRICATION SYSTEM
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.
EMS
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.
CLUTCH
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.
TRANSMISSION
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.
SILENCER
The new 350 EXC-F's silencer with
its large volume reduces noise levels to the stricter standards of the future.
WITH ELECTRIC STARTER
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.
OPTIMUM ERGONOMICS
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
