So I’ve ridden my ‘17 Husqvarna FC450 2 times now since having FC do the suspension (bike had 19 hours when I bought it...so it’s all broke in). The shock seems good, I’m happy with it. The forks seem harsh, front end always feels tall, will never settle into a rut (stays tall), etc. Suggestions on how to maybe soften these things up a big, get the front end “lower”, and get to track in ruts better? Any thoughts on adjustments?

Thanks!!!

Set the clickers to a neutral point, then let air out until it bottoms and then add a few psi back.

Don't pay attention to the numbers, pay attention to how it works

You have to check the air pressure constantly. The pressure will change with ambient air temp changes. I've had mine change 6psi from my basement to the track. I've noticed if the pressure raises in the forks it won't settle into the corners very well. I usually run my 350sxf around 142-145 depending on what track I go to. I'm 180lbs and +30 B

Thanks for the replies guys. I should’ve added that I’m about 155lbs and a +25/30A rider.

Thanks!!

Try less air in the forks. I'm closer to 200lbs and the stock 10,8 bar was way too much for me. I used to have only 10.0 bar in mine.

That gave me way more front end feel and traction.

And play with the clickers.

I haven't had the need to revalve my AER48s but in the past I had Factory Connection do a YZ for me and the forks were harsh in braking bumps and chop. With the feedback they ended up taking out some oil and slightly changing the shim stack and the forks felt great after that. I'm sure they can dial you in with some feedback provided.

I am a C rider. Same weight. 9.4 bar, 14 clicks out rebound, 12 clicks out compression. I set the air and then i only recheck the air when the fromt end begins to get harsh. Since i ride same 3 tracks most of the time, checking air is about once a month. I have 60 hrs on the bike. Only suspension mod i made was adding the NEKEN SFS TOP CLAMP, it's tits.

I know mine are setup from FC at about 146psi....sounds like I need to drop that air quite a bit as a starting point huh

I run mine at 140-142 psi, depending on terrain. 170 lbs, Vet rider. Compression 15 clicks out, rebound 15 clicks out. And I run mine on the third line. Works perfect!

A friend race a 350 SXF yesterday with 132 in the front end and won a moto. This was on a borrowed bike. Start lowering the pressure by 2 psi and see how it feels. My FC450 is set up by Race Tech and I am running a lot less air pressure than they recommend, like 8 lbs. less.

MXA had a good write up on setting up the AER’s. I thought they were harsh initially also. I just kept lowering the air pressure until they felt good. Absolutely love them now. They work really well once you figure out settings.

I only used my AER's for 3 races but they were at 3 different track and I really liked them. I was running 145psi. I had the comp on 16 comp and the rebound on 18. I was running them on the 2nd line and had the rear at 105mm of sag. They're definitely not cone valves but I think they're a pretty damn good fork for about 85-90% of each of the tracks that I raced them on, if that makes sense.

I'm on a 250sx 2-stroke but I weigh 155 and run mine at 141psi at most tracks.
I overjumped a 100ft ish jump last week to basically flat and I didn't die, I was happy with the forks during that screw up!

I ride a 17 fc350, 170lbs vet and run 142 most of the time. Have been real happy with bottoming resistance also as over jumping is handled well.

Not dying a massive over jump is a HUGE bonus Seth :-)

Have any of you tried higher air pressures? For my TC250, the stock pressure of 148 psi is approximately equal to 0.46 kg/mm fork springs. Going up one "spring rate" puts it at 153 psi. I've tried as low as 145 and as high as 160 and it feels better with more air and clickers adjusted to suit.

Edit: 190 lb vet B here.

erik- I'm out @ 3Palms all the time, and also have a TC250. I've tried both.. I'm more comfy at around 144psi. I'm also running a Sh*t load of sag- (106-108) (Stk spring) I'm close to 180lbs. I've tried 155psi, but I lost some plushness. I do some long motos, and about 4 laps in, I can tell the pressure starts to change. If I start @ 144psi, by the time I'm done, it goes up to around 148-150.

That bike is a blast to ride

I run a similar set up. 185 vet b rider, i think i finally got compfy at 156 psi through some down hill chop. But maybe my clickers just needed some tuning. ?

I've seen you out there I think. Fast house gear number 19? I can keep you in sight for a lap or so...haha. I've found sag at 106 is best compromise over turning and stability.

And you're right about the increase. Have to set it in anticipation of pressure rise.

My next time out I was going to try much lower pressure again just to see how it feels. I tried 160 psi last time and it was too much.

I could never get those forks right even after having them revalved twice. I weigh 154 and ran around 120-125psi (450sxf).Even at 120 psi i couldn't use all the forks travel. The 450 valving in the AER seems really stiff and harsh. Ive ridden 250sxf/350sxf with 145psi+ and it was a completely different fork. Nowhere near as harsh. I found on my 450 the fork worked well in softer conditions like sand but on a dry rough hard pack track it would beat me up in about 4 laps. Ended up getting a set of cone valves.

FYI, AER fork tubes bottom with 20mm of slider to spare. 12.2 in of travel.
