Hey I'm curious what you suspension guys are running for oil level in the outer camber in your AER48 forks?
Manual says 200cc
Racetech says 240cc

Bike is a 2017 ktm 450 sxf. Motocross track ridden only.

Also on the damping side the manual calls for 380cc in the cartridge. is that the best to run?

Thanks
-Sean

If they're stock I fill them back to 200cc, if I revalve them I use 180cc. The damper is a sealed cartridge so the 380 is what they recommend so there's enough oil when you install the base valve that there is no air pocket. then you compress the rod all the way and the excess oil is purged out the bleed hole at the top of the cartridge.

Is that to stop the rapid spring ramp up? I've gone 170cc on mine. Yet to test
Brian, have you done the kyb tech touch kits?

Yes, I soften up the base and make a floating mid and still don't have a bottoming issue. Unless RT is going really stiff and using very low air pressures I can't see a reason for using a larger oil volume, but if you use their calculator the still recommend pretty firm air pressures.

I have not installed the TT kit yet, only a set of Ohlins inserts. Anytime I've had someone scared enough about air forks to inquire they usually pucker up at the price and decide to go with my $200 fork revalve instead, lol

Yeah my guy did the same. I haven't ridden since I've dropped the oil but. I'm thinking this will be the trick.
