Checking the shock absorption rubbers in the rear hub*
Some of the LC4 models have a cush-drive rear wheel hub. For this pur-
pose, the engine power is conveyed from the rear sprocket via 6 shock
absorption rubbers 1 to the rear wheel. These 6 absorption rubbers wear
with increasing operation time, and should be checked for wear whenever
the rear wheel is dismounted.
For this purpose, lie the rear wheel on a work bench with the rear sprocket
upwards, and put the wheel spindle in the hub. Now hold the rear wheel
firmly and try to turn the rear sprocket. The rear sprocket may not turn
more than maximum 5 mm (0,2 in) measured on the outside. If the play in
the chain wheel is larger, all 6 shock absorption rubbers are to be replaced.
Check the shock absorption rubbers for signs of damage and dirt.

Tires, air pressure

Tire type, tire condition, and how much air pressure the tires have in them
affect the way your motorcycle rides, and they must therefore be checked
whenever you're getting ready to go anywhere on your motorcycle.
– 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.
– Tire pressure should be checked regularly on a "cold" tire. Proper pres-
sure ensures optimum driving comfort and extends the life of your tires.

Checking spoke tension

The correct spoke tension is very important for the stability of the wheels
and thus for riding safety. A loose spoke causes the wheel to become
unbalanced and before long other spokes will have come loose. Check
spoke tension, especially on a new motorcycle, in regular intervals. For
checking, tap on each spoke with the blade of a screw driver (see illustra-
tion). A clear tone must be the result. Dull tones indicate loose spokes. If
necessary, have the spokes retightened and the wheel centered by a KTM
dealer.
