Hi all

I am having an issue with my front forks where no matter how much I adjust the preload, compression or rebound, The front forks seem to bottom out/fully compress under braking. I recently replaced the fork seals and dust covered, removed the old fluid and added about 570mil of fresh 7.5w motul fork oil. My mechanic buddy says it seems to be an issue with the valving, but we arent sure how to fix the issue. he also has a 16 959 and when I match my settings to his, its a drastic difference. Does anyone know how to resolve this issue?

Call Dave Moss and have him instruct you on how to correctly set up (for your weight/ergo) and ultimately figure out what's happening.

Are you a certified fork tech? If not, give them to a professional to check and revalve.

Has anyone ever been inside the forks? When adding preload does it get more difficult the more preload you add? Or does it just click real easy all the way through.

I have been in contact with Dave moss and we still havent figured out the issue
If he's instructed you, and you've followed instruction and reported back - to the T - then I believe there's something wrong with the forks. It can't be much else, unless there's something you're not telling us. Like perhaps when you took them apart you didn't document the shim stack and put them back together wrong...?

The 959 comes from Italy soft in the front and stiff in the rear. Dave Behrend at Fast Bike Industries is probably the best in the business if you decide to send them to a professional.

I have an 18 959 for street and track days (B group). Dave Moss recently adjusted my suspension at a Laguna track day. The rear, he was happy with, the front, however, after maxing out the settings continued to bottom out under heavy braking. He basically told me to upgrade the suspension. I am about to upgrade to Ohlins Nix 30 cartridges. I am average height and weight, 5'11, 175, just a heavy braker according to Dave.

I have a similar issue when at the track. I've learned not to push it and just enjoy the day when I'm out there. I'm aware of the mechanical limitations and it doesn't bother me - I don't get a trophy at the end of the day ;)

True it’s more important to enjoy the day and ride safe. Unless you want to spend the big bucks to do the suspension. In that case I recommend take the bike to race tech suspension in CA. Show them what’s going on and they will look at the bike and set you up.
