Running In The Engine; Starting Power Of Lithium-Ion Batteries At Low Temperatures; Preparing The Vehicle For Difficult Riding Conditions - KTM 450 XC-F Owner's Manual

7 PREPARING FOR USE
(All SX‑F models)
–
Do not take luggage along.
(XC‑F US)
–
If you carry any luggage, make sure it is fixed firmly as close as possible to the center of the vehicle and ensure even weight
distribution between the front and rear wheels.
Info
Motorcycles react sensitively to any changes of weight distribution.
–
The maximum permissible weight and the maximum permissible axle loads must not be exceeded.
Guideline
Maximum permissible overall weight
Maximum permissible front axle load
Maximum permissible rear axle load
–
Run in the engine. ( p. 17)
7.2

Running in the engine

–
During the running-in phase, do not exceed the specified engine speed and engine performance.
Guideline
Maximum engine speed
During the first operating hour
Maximum engine performance
During the first 3 operating hours
–
Avoid fully opening the throttle!

Preparing the vehicle for difficult riding conditions

Info
Use of the vehicle under difficult conditions, such as on sand or on wet and muddy surfaces, can lead to considerably more
rapid wear of components such as the drive train, brake system, or suspension components. For this reason, it may be neces-
sary to inspect or replace parts before the next scheduled service.
–
Clean the air filter and air filter box.
Info
Check the air filter approx. every 30 minutes.
–
Seal the air filter box.
–
Secure the air filter box lid.
–
Check the electrical connector for humidity and corrosion and to ensure it is firmly seated.
» If humidity, corrosion, or damage is found:
–
Clean and dry the connector, or change it if necessary.
Difficult riding conditions are:
–
Rides on dry sand. (
–
Rides on wet sand. (
–
Rides on wet and muddy surfaces. (
Lithium-ion batteries are far lighter than lead batteries, have a low self-discharge rate,
and have more starting power at temperatures over 15 °C (60 °F). At low temperatures,
however, the starting power of lithium-ion batteries drops to below that of lead batter-
ies.
Multiple starting attempts may be needed. Press the electric starter button for 5 sec-
onds, and wait 30 seconds between attempts. The pauses are necessary so that the
created heat can distribute through the lithium-ion battery and the battery is not dam-
aged.
If the charged lithium-ion battery does not or only weakly turns over the electric starter
when temperatures are below 15 °C (60 °F), then the battery is not faulty, but needs to

be warmed up internally to increase its starting power (current output).
The starting power increases as the battery warms up.
