I notice that the KYB guys are either using SSS or PSF1 forks. Why no PSF2, and what was the point of developing it?

Most likely, the guys NOT running Showas. Just a guess on my part, though. Tongue

The factory level guys who are running Kyb. What got me thinking about it was you mentioning that Chad could choose between SSS and PSF1 if the Yamaha thing happens next year.

I personally like the PSF1 over the 2 or TAC, JMO though.

I was just making sure that this wasn't a conspiracy theory that people were secretly using spring forks, ha.

PSF2 is a less advanced fork and resembles an old open-bath style fork design. It's performance isn't too far off of PSF1 for the general consumer, but at the Factory level PSF1 offers more capabilities.

Makes sense. So was the purpose of the PSF2 to lower production cost? Barring that, it seems like a backwards move when a few years ago Honda/Kawasaki were equipping consumer bikes with the PSF1 forks.

PSF2 was an attempt at lowering production costs, but Honda has adapted it in Japan on their race bikes (a works version) which they're learning a lot from.

Thanks Michael.

With SSS being considered the holy grail by many, what are your thoughts on the capabilities of the PSF1 forks? Just curious, not trying to start an air fork bashing thread, I think they're here to stay whether everyone wants them or not.

Kit KYB (not really an A-kit vs B-kit difference like Showa).

Enzo can give you exactly what Cooper Webb runs (minus this special cartridge cap for the forks). I really enjoyed my time there. Check the forks on the bike in my sig.

How would you say it compares to A-Kit stuff?

Completely depends how it's set up. My favorite set of forks I have are a set of Kit KYB PSF1 forks that Ross built me (KX450F).

You could do small story with photos about forks for homepage? PSF1, PSF1 factory and PSF2... and even Suzuki have now ones where compression is in bottom of fork?

I would be really interested to see a comparison article, in ML experience, for the kit KYB PSF1/KIt KYB SSS/showa A kit spring/ showa A kit TAC. There have been a few reviews posted up from normal folks on A kits (my review included) but what's really missing from a research standpoint prior to dishing out the dough is someone that understands suspension and has ridden various types for a valuable comparison. Some of us like to spend $ on top notch things (even though we don't need them) but lack the info online for a solid comparison.

yeah! Get Bones Bacon, Ross Maeda, WP Factory Services, Ohlins USA, and Roland Solva (with a translator or 2) over to Glen Helen to do a badass ultimate suspension shootout on 5identically prepped 450's.

GuyB, open up that fat VitalMX checkbook and make it happen!

I have a slightly unpopular opinion here, I prefer the PSF1 for moto applications over the SSS.

interesting you say that, I have a 2013 kx450f with stock forks and the only issue I have noticed is they do build air psi throughout the day ....I was at lacr the other day and set them at 34.5 lbs and in just a couple hours they jumped up to 37...I was pretty surprised but it was hot that day also! after all the negative reviews ive read and heard I have not experienced anything that would cause me to rush out and get them revalved or look for some spring forks!

Yes, I'm sure, but maybe you should ask JGR's suspension guy or MB1 Texas... I don't care for so many accounts messing around like this.

Only thing missing is some talk about rear holeshot device!

But seriously...ML512, any hope in the future for some sort of comparison of kit suspensions on similar set up bikes? Showa A kit vs KYB Kit vs Ohlins vs WP Cone valve, etc? That would be a great thing to see! I'm the guy that spoke to you on the phone awhile back about the 2015 Kx450F forks vs A kit forks. Ended up pulling the trigger on an older spring PC kit suspension (forks/shock). Or would an article like that be pointless as they all function at such a high level that it comes to set up and personal preference?

Lol... I can see the axe falling ever so slowly on this guy

I always wondered about switching suspension components between brands. I don't know enough about it, but is there some reason since people (mxa) always rave about the SSS spring forks... could you or would you want to rip those off a YZF and put them on your insert-brand-here bike?

I personally would like to hear a legit, unbiased comparison. as i am in the market as well... So many options that cost so much.. hard to pick whats best and feel solid about it because of the so many different kits available.

Even with Kit level suspension, I think there are a few factors beyond which is best. Such as "who are you getting them setup by, what bike are they going on, what's your budget?"

As much as I'd love to do that test, getting Showa A-kit spring and TAC air, KYB PSF1 and AOSS kit, WP CV/Traxx, and Ohlins for the same bike would be quite difficult...

i can agree with the difficult part.. what if after the test you posted them for sale to the public? and maybe do a fundraiser for the money that would be lost due to them not being brand new? idk like a social bar event or something and proceeds go to vital for their services.

Let's discuss "Why" the PSF1 is soooo much easier...to me...to get dialed and adjust for various tracks...?

My 1st inclination is "because, it's simpler":

One Air Adjustment and a touch of rebound makes micro-adjusting (fine tuning for me).
Compression adjustments seem to be lowest on my list of necessities on a PSF1...why?

Micheal, I'm all ears, here...

The problem would be scrounging the cash to buy them in the first place! That's a lot of coin! I could get some loaners... but I'd have to buy the other half... That's not a work expense, that's out of my bank account kind of stuff. I don't want to invest that kind of money in a project.
