This is a quick video on how to replace worn out or broken front fork Oil seal of KTM Duke 390, the job was done at KTM Authorized service center with company replacement parts. Total job time is about 1 hour. Its risky to ride a duke 390 with broken seal because the oil directly falls on to the discs and drastically reducing the front brake bite literally causing more like a front brake failure, to add this also affects the shock absorption action during riding. The seals must be replaced with OEM parts. Usually the Seals fail due to dust getting in through the dust cap..or by age. in my case the bike haven't been ridden for last 5 years, This bike has run only 800kms in five years and the oil seals failed due to non usage. My normal practice is if the oil seal fails on one fork leg, i prefer to replace it on both the fork legs as am sure the other one has taken the same beating as this one and will fail eventually. To save time and effort, better to change on both he fork lets.
