KTM 990 SUPER DUKE - Manual (Page 53)

Battery
The battery is located in the front spoiler in front of the engine and is maintenance-free. It
is not necessary to check the electrolyte level or to refill water. Simply keep the battery poles
clean and slightly grease them with an acid-free grease if necessary. The charge condition
and type of charge are very important for the battery's service life.
Never operate the motorcycle with a run-down battery or without the battery. This can dam-
age the electronic components or safety equipment in either caseand the motorcycle will no
longer be roadworthy.
Never remove the closing cover [1] otherwise the battery will be damaged.
– Tire type and size can be found in the technical specifications and in the homologation
certificate.
– Tire condition has to be checked every time you want to ride your motorcycle. Before
leaving check for punctures and nails or other sharp objects that might have become
embedded in the tire.
– Refer to the specific regulations in your country for minimum tire tread requirements.
We recommend replacing tires at the latest when the tread is down to 2 mm (0.08 in).
– Tire pressure should be checked regularly on a „cold“ tire. Adapt the air pressure to the
motorcycle's total weight. Proper pressure ensures optimum driving comfort and extends
the life of your tires.

– Do not mount tires which have not been
approved by KTM. Other tires could have
adverse effects on the way your motorcy-
cle rides.
– Use tires of the same brand and type for
the front and rear wheels.
– For your own safety replace damaged tires
immediately.
– Worn tires can have a negative effect on
how your motorcycle performs, especially
on wet surfaces.
– If air pressure is too low, abnormal wear
and overheating of the tire can result.
– New tires have a smooth surface, which
means that they must be run in to achieve
full grip. For this purpose, ride the motor-
cycle carefully at moderate speed during
the first 200 kilometers (125 miles) with
new tires, tilting the vehicle at different
angles so that all sections are properly
roughened. Tires will not display their full
grip characteristics until they are properly
run in.
– For reasons of safety, it is recommended
to exchange the valve insert whenever a
new tire is mounted.
