Checking Spoke Tension - KTM 400 Owner's Handbook Manual

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 unba-
lanced 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 screwdriver (see photo). A clear tone
must be the result. Dull tones are indicators of loose spokes. If necessary,
have the spokes retightened and the wheel centered by a KTM dealer.

Checking the shock absorption rubbers in the rear hub*
Some models have a damped rear wheel hub. For this purpose, the engine

power is conveyed from the rear sprocket via 6 shock absorption rubbers
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.
