• Powerful engine characteristics<br />
• Extremely <strong>com</strong>pact<br />
• Wide rev range<br />
The <strong>com</strong>pletely new 350 cc power<br />
unit is <strong>com</strong>parable with nothing ever<br />
seen before. It is neither a small<br />
450 nor a “bored out” 250; it has<br />
a character <strong>com</strong>pletely of its own.<br />
The primary reason for this is absolutely<br />
minimal moving masses.<br />
The engine therefore runs extremely<br />
quickly in the rev range where<br />
most power is generated and<br />
impresses with unprecedented<br />
playful handling. Very mellow from<br />
low down and a real beast at higher<br />
engine speeds. You need to try it<br />
yourself to see how that feels.<br />
DOHC<br />
cylinder<br />
head<br />
Precision engine construction:<br />
four titanium valves are opened<br />
by twin overhead camshafts, the<br />
8 g super-light cam followers are<br />
DLC-coated. This makes speeds<br />
of up to 12,000 rpm possible.<br />
First Oil Filling<br />
for all KTM Engines.<br />
Engine<br />
management<br />
The engine management system from Keihin with electronic fuel injection<br />
and 42 mm throttle body ensures powerful responsiveness across a very<br />
broad rev range. Very smooth, very even, very efficient – a new dimension<br />
in enduro rideability.<br />
Standard equipment: electronic cold-start enrichment and automatic<br />
adaptation to temperature and altitude conditions. Reliable energy<br />
provision is taken care of by the powerful, oil-cooled, 196 W alternator.<br />
With an optional map-select switch and the user-setting tool<br />
(PowerParts), additional engine characteristics can be activated at<br />
the press of a button and the ignition and injection mapping can be<br />
individually adapted on a laptop via a USB interface.<br />
Electric<br />
starter<br />
As standard with both kick and<br />
electric starters. The electric<br />
starter drive is integrated in the<br />
ignition cover and designed to be<br />
very small and <strong>com</strong>pact. Those<br />
who prefer it can convert to pure<br />
kickstart operation. This saves an<br />
extra 1500 g for weight purists.<br />
CLUTCH<br />
Innovative: single-piece, machined<br />
outer clutch hub without<br />
rivets featuring lining disks on<br />
slim steel carriers. The design<br />
guarantees maximum durability<br />
at the same time as a very flat<br />
construction. Pre-tensioning by<br />
means of a central spring washer.<br />
Without the conventional conical<br />
springs, there’s enough space<br />
for an integrated, transmissionfriendly<br />
back-damping system.<br />
Standard equipment: hydraulic<br />
clutch actuation from Brembo.<br />
(see page 16).
