GENERAL TIPS AND WARNINGS FOR STARTING THE MOTORCYCLE 

»

– Dress properly for the ride. Smart KTM drivers always wear

a helmet, boots, gloves and the right Enduro/Motocross

clothing. Protective clothing should be conspicuous to make

sure other road users see you in time. 

– Do not drive after drinking alcohol. 

– Always switch on the light while driving to make sure other

road users see you in time. 

– Only use accessories approved by KTM. 

– Always use front and rear tires with the same tread pattern. 

– The 250/450 SX-F models are designed and built for 1

person only. No passengers are permitted. 

– Adjust your speed to the conditions and your driving skill. 

– Drive cautiously on unfamiliar roads or in unfamiliar terrain. 

– Always have a friend accompany you on his bike when driving

off road so you can help each other if you run into trouble. 

– Replace the helmet visor or the lenses in your glasses in time.

A scratched visor or scratched lenses can make you practically

blind in back light. 

– Never leave your motorcycle running unattended. 

– 250/450 SX-F models are not permitted on public roads and

highways. 

– When riding your motorcycle, please remember that excessive

noise may disturb others.

Instructions for initial operation

– Make sure the work for the “pre-delivery inspection“ was

performed by your authorized KTM workshop. The DELIVERY

CERTIFICATE and SERVICE MANUAL will be handed over

when you pick up your vehicle.

– Read these operating instructions carefully before your first

ride.

– Familiarize yourself with the operating elements.

– Set the clutch lever, the handbrake lever, and the footbrake

pedal to the positions that are most convenient for you.

– Get used to handling the motorcycle on an empty parking

lot or open space, before starting on a longer drive. Also try

to drive as slowly as possible and in a standing position, to

improve your feeling for the vehicle.

– Do not drive along off-road tracks which go beyond your ability

and experience.

– Hold the handlebars with both hands and leave your feet on

the foot rests while driving.

– Remove your foot from the foot brake lever when you are not

braking. If the foot brake lever is not released the brake 

pads rub continuously and the braking system is 

overheated.

– Do not make any alterations to the motorcycle and always

use ORIGINAL KTM SPARE PARTS. Spare parts from other

manufacturers can impair the safety of the motorcycle.

– Motorcycles are sensitive to alterations in the distribution of

weight. If you are taking luggage with you, this should be

secured as close as possible to the middle of the vehicle;

distribute the weight evenly between the front and rear wheel.

Never exceed the maximum permissible laden weight and

the axle weights. The maximum permissible laden weight is

comprised of the following components:

– Motorcycle ready for operation and tank full

– Driver with protective clothing and helmet.

– Pay attention to the running-in procedure.

Running in

Even very precisely machined sections of engine components have

rougher surfaces than components which have been sliding across

one another for quite some time. Therefore, every engine needs to

be broken in. 

For this reason, do not load the engine more than 50% of its capacity

during the first 3 operating hours. Besides, the engine speed must

not exceed 7000 rpm. Avoid going full-throttle!

In the following 12 operating hours, you may load the engine up

to 75% of its capacity.
