Just got my 2017 450 and am looking for the same info.

I'm 165# naked. I'll have to weigh my latest gear to get the total.

I put the first 1.5 hour on the bike yesterday with the forks loaded at 145# and the rear spring at stock preload.

Looking forward to reading about everyone's experience.

We weigh about the same, try 138lbs in fork. The rear spring will be real close to being to stiff. Comes with a 4.5, you might need a 4.3. Hope this helps.

I have a 16 FC350 and did the AER48 swap. I absolutely love my suspension setup! I have had my front and rear valved as well.
Best suspension I've ever ridden. I've let multiple people ride my bike from C riders to local pro and they all say it's awesome as well.

hy

I got just 8 hours in my 17 sxf 350 with aer forks. I had a 250 crf honda from 2006 before. The WP is a lot better. I do only have 8.5 BAR pressure in it for my 90 kg and for me it still feels a bit stiff. I guess I'll figure out and try your pressures too.

Also please help me. Last time a let the front legs bleed from the left leg some moisture had come out too. Is that normal, or do I even have to bleed the left leg? I attach a photo of what I try to explain. Thanks heaps for help!

crucial to bleeed both legs as usual. stiff is because you are running to low pressure. 145-155 psi is what you need, and a 48 rear spring

First i tried with 10.8 bar and it was hard as a rock for. Of course after the honde everything will be harder

Use the recommended pressure and make it softer on the damping side. The AER48 I've ridden had too much compression damping. Remember that the air is the spring and that it has nothing to do with the damping. As a starter you can use the settings from MXA: http://motocrossactionmag.com/mxa-race-test-2017-ktm-350sxf/

Even if 10.8 felt stiff, 10.1-10.5 should be OK. We have 75kg C riders running 10.5.

I have experienced issues where the fork lock to high in the stroke, feels stiff and working 2-4cm higher in the stroke. Then it is a fork issue.

180 oil created same feeling. And don't forget to bleed both legs.

Send them to Craig Decker, don't even mess around. The valving sucks stock.
He is the best with suspension.

Get them valved right so you can run the correct Air Pressure. I run 155psi at 188lbs, I love these forks.

Thank you all for your help. I just made the crucial oilchange at 8 hours. All set up so I'll try out this weekend. Let's see how it turns out

Why is there oil in the air side? Compression and rebound are handled on the right, Air on left.

Yeah just thought of that when I posted. A open oil bath to reduce stiction.

The air side has oil for bottoming and lubrication
240cc are in each fork

180-240 is the range for both sides I run 180 in the air side and 200 in dampening side

Man, this is all so bloody confusing!, I wish I understood more about suspension in general, let alone my AER's,

Everything is set to stock and I bleed the air out, & keep about 145psi and just hang on!.

Be nice to know if by making a twist here and a click there could improve my riding and comfort, but where do you even start?, so as said, I just ride it.

Watch that video
On our forks Airside acts as a spring or spring rate which is designed to hold up a certain amount of weight to then evenly transfer suspension travel to the dampening side Which internally controls the speed at which oil can travel through the various valves and shim stacks such as "compression valve shims and stack" "rebound valve shims and stack" and "mid valve shims and stack" at certain levels of impact and velocity. Your clippers are a sensually adjusting that flow by opening more room for the oil to flow or less room.

This AER 48 fork sucks period. I put like $500 in to them, ENZO revalved several times and they still suck! Blowing true the stroke and harsh on landing and bouncing back on big jumps landing. I had ENZO put in them the KYB SSF Yamaha internals and wow different bike . It was like riding on pillows after that, well almost ha ha. I was ready to sell the bike before that I was so frustrated with the fork . Now I love the bike again. Before this Ktm I had 2015 YZ450F with the some fork but for some reason this fork works better on the Ktm because of the steal frame! I ride my buddies Ktm with the cv fork and my fork was as just that good.
So if U like the fork ,keep it but if u are frustrated with it then don't waste your time on it.
This is just mine experience and opinion, probably different for other people.

Bouncing back on jumps, blowing through the stroke... hmmm....

Let me guess, your sag was 92mm, you had 135lbs of air, and had compression all the way open trying to make them softer.

These are the best forks I have ever had, so I don't understand your post.

I have honestly been extremely happy with it . Enzo suspension is known for doing KYB they are not known from WP. With that said SSS forks are amazing however I think you really need to go with the suspension shop that has each individual fork design figure it out. Secondly if they don't do testing and/or don't have consistent access to a suspension dyno with that specific design then I believe your wasting your money. Because then essentially they're guessing on valving set up. Not only that each individual shop has their own basic said philosophy on how to tune and most of them are based on facts and science. however that does not necessarily mean you're going to get the same results across the board. And yes that means that shops that know what they're doing and do a good job they Absolutely have job security now because that is what they do and it isn't what everyone else is doing. If you have someone you trust and you know has made you happy in the past then don't hesitate to use them. I can do all of the work myself I know how to work on my suspension however I'm getting ready to spend $1500 on having my suspension set up by shop because I don't have that expertise on tuning. Just my 2 cents

Learn how to ride a bike better. Then learn exactly what your suspension is doing. You sound completely clueless to be honest. And Enzo did a complete re-valve for $500.00.....haha , yeah ok , sparky. You only get the forks done...and not the shock I guess. Probably unbalanced as all hell. What a dumb post.

I still stand by my statement that the gm of a major suspension shop told me every rider preferred the spring conversion over the air.
I had already switched back to Yamaha by then so it wasn't to get my business.

I have a set of Cone Valves and the AER48's and I think the Air forks do a few things better than the spring forks do and I am comparing them to my Cone Valve forks. My air forks have been re-valve'd, they are better at bottoming resistance I feel like you can jump off into things with more confidence charge down hills with big braking bumps. They have better traction interring off camber corners and they are better when the braking bumps turn into small whoops they follow the ground better witch gives you more control and they are way lighter then a spring fork and you can feel it overall . Don't get me wrong the Cone Valves are really good and the are plush but if my 2016 450 had came with the AER forks and not the 4CS I probably wouldn't have spent 3 grand on forks.

Seriously man , of course they did the shock to but we are talking about the forks now right? And trust me I probably know more about suspension than your dumb ass . The air fork just don't work for me, everybody is different. ,plus u don't know me u don't know where I ride or anything.so next time before u open your stupid mouth think a little bit.
Why are you even in this thread anyway? I'm pretty sure you don't even have a KTM. You are one of those fat duche bags that sits all day in front of the computer replying to every thread on here and doesn't even ride,

Haha...this is classic.

1st...I own a 17' Husky 125. AER's up front...and both front and rear have FC re-valve , sprung and setup for me.

2nd...I'm 6'-1" tall and weigh 185lbs. And extremely fit for my age you goon.

3rd....we are talking forks , but if you knew anything at all about suspension you should know that the shock and forks need to be set up to balance the bike out.

You....just had your forks done...and don't understand why they feel like shit? LMFAO! And if I need to know anything about you I'll just look up Brandon's first race " on YouTube....you're the star in that video. Haha.
