Dismounting and mounting the rear wheel
Jack the motorcycle up on its frame so that the rear wheel no longer touches
the ground.
Remove the collar nut [1], remove the chain tensioner [2] and pull out the
wheel spindle [3] until you can push the rear wheel forwards.
Take the chain off the rear sprocket, pull out the wheel spindle and carefully
remove the rear wheel from the swing arm.
– Do not operate the rear brake when the rear wheel has been
dismounted.
Make sure the brake disc is always on top when you lay down the wheel,
otherwise the brake disc can be damaged.
If the axle is dismounted, clean the thread of the wheel spindle and col-
lar nut thoroughly and apply a new coat of grease to prevent the thread
from jamming.

Tires, air pressure
Tire type, tire condition, and air pressure level affect the way your motorcy-
cle rides and must therefore be checked whenever you are getting ready to go
anywhere on your motorcycle.
Tire size can be found in the technical specifications and in the homolo-
gation certificate
Tire condition has to be checked every time you want to ride your motor-
cycle. Before leaving, check tires for punctures and nails or other sharp
objects that might have become embedded in them.
Refer to the specific regulations in your country for minimum tire tread
requirements. We recommend you replace the 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. Proper pres-
sure 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 motorcycle behaves.
front and rear wheels may only be fitted with tires having the same tread
layout. Use homologated tires
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
The rear wheel is remounted in the reverse order. Before tightening the col-
lar nut to 80 Nm (60 ft.lb), push the rear wheel forwards so that the chain
tensioners lie on the tension screws.
If you don’t happen to have a torque wrench at hand, make sure you have
the tightening torque corrected by a KTM dealer as soon as possible. A
loose axle may lead to an unstable driving behavior of your motorcycle.
After mounting the rear wheel, keep operating the rear brake until the pres-
sure point returns.
It is very important to keep the brake disk free from oil and fatty matters,
otherwise the braking effects would be strongly reduced.
Tighten the collar nut with the required torque. A loose wheel spindle may
lead to an unstable behavior of your motorcycle.
