Kawasaki Ninja Service Manual: Inner Tube Inspection

Kawasaki Ninja Service Manual / Suspension / Front Fork / Inner Tube Inspection

If there is any damage, replace the inner tube. Since damage to the inner tube damages the oil seal, replace the oil seal whenever the inner tube is replaced.

NOTICE

If the inner tube is badly bent or creased, replace it. Excessive bending, followed by subsequent straightening, can weaken the inner tube.

Inner Tube Inspection


If you feel binding or catching, the inner and outer tubes must be replaced.
