Looks like the fork seals M. Be careful when riding you don't punch that fender up against the triple tree braking.
Hi M. If you have it yes. I imagine that by looking at the level of compression under stationary braking you are getting it would be dangerous. Also adds an air of gravitas to the situation and you don't have to hang around at the dealer. I just did some looking online and it doesn't appear that Harley front shocks (I didn't know either) are very robust. You might be able to negotiate on some good cartridge shocks. Sure it was a company advert
Agree with JD.
Wipe them down first give them a few pumps wipe again , repeat.
Ride it for a bit to see if it persists.
If it does follow the vid that magnum posted, 9 times out of 10 it will fix the problem because you have a bit of grit in there not a blown seal.
Don't know if Harley cover seals under warranty but can say a lot of other manufacturers don't.
