Go check all 4 tires on your ride in the AM and again at 3. After a while you get sick and tired of that shit.
Air forks are worse. We have a long thermometer in our riding months.
Especially those in the high desert. Teens to 30s at night and 60-90 during day.

Its a headache.

All I want is a set of TAC forks for my KX 250.... All you guys switching to spring want to send me their garbage forks? Wink

I -HATED- my KYB Airs (13-14 KX450F) & was going to slap my "Made for Me" Enzo fat-lugged KYB spring forks with all the cool coatings and parts.

The engineer at ProCircuit, Patrick Doran, said..."Hey, do me a favor? Try our re-valve and internals & caps on your Airs -before- you swap them out and let me know what you think. Ok?"

I did. They are better than my springers. No shit.

Now, there's a legitimate bitch by those that say, "WTF, Dude! How much money was that?" And that's a legitimate bitch. The caps, mid-valves and revalve-service can cost a lot.

But, they can work. They do work.

If Pinger had a set built, for him, by Bones? He'd change his tune.

However, the pont to be made is this: if the manufacturers want us to like air-forks, they need to sell a set that's got settings that DON'T SUCK!

My guess would be that Ping has likely tried a set of fully setup PC airforks. The last I had seen he still has a good relationship there from his racing days and runs them on his personal bikes. They just aren't for some riders who want a specific feel. Remember all the different things Ping has ridden in his day, he knows what good is, and he knows what he wants at this point. It doesn't mean air forks or the PC setup isn't good or doesn't work, it just means it isn't the feel that he likes... in this case doesn't even sound like in the ball park.

From my experiences dealing with our riders, air forks can definitely be made to work for many riders. I do have a handful (not a big handful) in fact that LOVE the airfork. I have a lot who say the air and spring fork are comparable. And I also have a couple handfuls who won't even touch an airfork or test with one.

One interesting thing my boss mentioned to me, "How often do you hear someone say, 'gee I sure wish I had some airforks'? And how often do you hear someone say, 'I just wish I had spring forks!'"

Yes, the 2nd one is heard often which is the reason they spent the time and resources to develop our Spring Conversion System. You wouldn't believe the number of customers that would call the shop asking if we had a source for older spring forks to replace their air ones. There are two reasons this kit sells...1) They miss the spring fork feel or 2) They simply don't want to deal with the headache of checking pressures.

With all that said, if you haven't ridden a set of well setup airforks, it's hard to say whether you will or won't like them.

The last time I talked to Graeme Brough (ex factory suspension tech) he said the KYB PSF2 air fork is basically a "early 90's open bath fork with pretty fork caps to make it look high tech"

Contrary to what the OEM's would like the consumer to believe, technology is actually going backwards, not forward.

It's all about manufacturing cost and marketing.

Wow, you talked to someone and they provided an opinion and you went with it. Awesome! And let me guess, someone also told you that it's all about mfg and cost reduction. Again, awesome!

And the old school spring based forks are moving forward too I suppose.

Not at all correct, I didn't "go with" anything.

I was just stating what a suspension tech had mentioned and you formed your own opinion. Let me guess, you have air forks on your bike?

I think there are benefits to both designs but they are definitely not the product the OEM's would like us to believe. Nothing more, nothing less.

@moto0852. Read the article again, my comment on evolution has nothing to do with air forks, it's relating to Pingree's response on the second question posed to him. I made no comment on whether air forks are better or not, just that a poll could be interesting, and then later, I commented on the fact that I have been enjoying my TAC forks.

@ steve_97060. I know right Wink

Saddening???

How so?

Dude has an opinion, just like you, and he doesn't like them. A LOT of other guys would agree with Pingree.

There is a reason factory guys are going from air to spring forks. Are they also in denial? Or do they just know what works and what doesn't?

Again, no comment was made about air forks being better or worse. The fact that factory guys are not choosing to run air forks is interesting. Perhaps after riding at their level for so long with spring forks, the benefits (if any) of the air forks are out weighed by the learning curve that new air forks present. We can only speculate.

I also have no experience with the PSF versions of the air forks, only the TAC version off of the '15 kx450f (my personal bike) and the '16 kx450f. Other than valving changes and a seal redesign, I believe the '15 and '16 TAC forks are unchanged, yet the '16 kx got great reviews and the suspension was not shunned. I will admit that they are hard to set up, but once setup, it seems most peoples opinions change for the better.

And yes 'saddening' is correct, and yes 'saddening' is my opinion, BUT, in light of all that has been done scientifically to demonstrate that the theory of evolution is in fact an accurate explanation to show how we and other species came to be, it's hard to have an 'opinion' on the matter. Note, scientific 'theories' pretty much mean 'facts'. It's a shame they use the word 'theory'.

Has any body actually got any numbers to back up the idea that air forks are being pushed down our throats due to manufacturing costs and marketing reasons? Any comparative costs between spring SFF and air SFF? They're serious questions, don't get offended.

"Contrary to what the OEM's would like the consumer to believe, technology is actually going backwards, not forward"... This is ridiculous (You can be offended now).

There are legitimate reasons to pursue air as a means of suspending a motocross bike. Yes, there may be teething problems with the design etc, and at this point it is possible that springs offer more benefits to the consumer than air does, but to say technology is going backwards is a bit silly. I trust the engineers over in Japan will have the air forks working better than any spring fork. I guess only time will tell.

Funny thing: In virtually all 2016 shootouts, including Vital's, the KX air forked equipped bike finished ahead of KTM. Even MXA likes Honda and Kawi air forks.

Too funny.

I had FC fetted forks on my 15 CRF and they were awesome, I have a 16 KXF and just got them back from FC....again very happy with them. Yes air forks require more setting up and tuning to the track and conditions thats what you get with technological progress, more options, more chances of getting wrong if you dont get how to set them up properly/tune them for each track.
i think i would belive David Pingree before all the key board warriors.

Air forks take less material to be produced. Less material = less cost (and less weight of course).

What Pingree raised as the issue "They are harsh-feeling on smaller bumps, they don't have the feel of a spring fork in sweeping turns or racing surfaces with less traction and you have to set aside about forty five minutes to check air pressure/clicker/adjuster/sag settings prior to going on the track" is exactly why we gave up air forks in the 70's (had them on my CR and RM's) and is the same conclusion I came to. Air just cannot react the same way as a spring, it ramps up resistance much faster than a coil spring. They were great on really big slow speed hits, but could not handle the braking and acceleration high speed chatter the way a spring could and you lose some feel in sweeping terms as the air did not follow the terrain the same way as an air fork.

When I bought a new CRF450 in 2013, I went out of my way to find a left over 2012 w/o the air fork or dual exhaust.. I would rather fix the flaws of the older bike than deal with what the corporate accountants and marketing spin doctors wanted me to ride. Very smart people make very stupid decision in big companies because of the politics.. I see it first hand everyday.

The multiple air chambers help deal with the air ramping up too fast compared to a coil spring and to get a better feel, but then you have complicated the air fork too much by trying to fix its flaws.

My experience was with a new 13 CRF450. Forks were simply terrible no matter what settings we tried they never worked. Then replaced all the valving and still no good. We also found that some 13 air forks worked better than others out of the crate but no one could work out why?

Another problem was the CRF dropped all its oil out of one fork the day before a race meeting. That was game over for the next day.

I'd come off a 450 YZF running Ohlins cartridge kit on the front and Ohlins back and getting on the Honda was not a good experience.

I'm on a Husky now with 4CS forks and they are about to get binned for Ohlins too.

IMHO my FC revalved 2014 Honda forks are pretty darn good..could definitely be better though..My biggest complaint is also sort of a compliment too, is that I can either make them super plush with harsh bottoming, or I can make them not bottom on practicly anything but feel harsh on smaller stuff.
I think this has been suspension tuning's biggest challenge with spring forks also.
As of rite now I have a pretty decent compromise. I tend to run them a little firmer cause I hate the way they dive when set up too plush.. But with those couple exceptions... I like em.

Give me a call at FC next week. Tom Wallace

Yea, because a SX star and Manuel Ornelas will come to the exact same conclusion on fork performance, like, yea, bro, and stuff.

Its hard for people who drop 9 grand on a bike to say this is worse than my 199X Upside down Kawi forks.

When racers getting paid to ride shit are swapping to springs with air stickers....just saying.

Was prepared to hate air forks, but I have revalved KYB PSF-1s on my KX...and they are fantastic.

Any SFF system I have rode, spring or air, I was not a fan of. I think the triple air forks are a flawed concept and very difficult to keep a good setup consistently dialed in.

Get your tin foil hats out...

No, the teams aren't running spring forks with air stickers... Quite a few teams have done comparison tests and have given the rider's a choice in what they want to run.

so just because Ping doesn't like them no one else should? You do know Ping's riding ability is totally different to the majority of other riders don't you? I am a expert racer (was pro but too old for pro now), and they are fine for me if setup correctly, just like any other suspension.

Seriously though It's not like that scenario hasnt happened before, with everything from goggles to oils to tires and engine parts.

Currently, the teams are running what they state they're using. I've only seen it done once so far, and it was just at one race with one rider.

I have a 2015 kx450 and I HATE! the forks with a passion. With spring forks I've had no problem in the past finding a setting that works great, requiring only 1-2 clicks of compression or rebound depending on track conditions. With the air forks, the setting that works great at the hardpack track is horrible at the sand track. I made a huge mistake buying the bike though. Got a good deal on it through a local dealer and since my sone wanted a kx250f I figured might as well. The bike handles like shit, and I can't wait to sell it and get back on a KTM or Yamaha 2 stroke with spring forks

Once dialed, the same should be with the air fork. Take the time to find the correct pressures and stick to those and adjust clickers from there pending track conditions.

One would think this. I have a friend who is a trusted susp. tuner and he has worked with me. I don't think I am that picky, but the air fork requires major changes, depending on ambient air temp and humidity.. Personally I think they are just to much work. I just want to get on my bike and enjoy riding it, not spend all day chasing an elusive setup that is confidence inspiring.

I have a 16 KX450 with stock valving in the forks and shock. All I did was add a 5.8 sprint to the rear. The forks (once the pressures were tested and dialed in) in stock trim are better than my FC revolved 2011 RMZ450 Showas. It seems like Kawasaki really turned a corner in 16 with these forks. The 15 as well as the Suzukis have not been well received. I was scared of these forks when I bought the bike by after day 2, I knew they were good.
