I was reading a few threads from about 6-7 years ago that were referencing the difference between A-kit suspension and stock. Now that it is 2022, has suspension evolved and closer to A-kit? What makes A-kit suspension different now?
I am genuinely curios as I have never ridden A-Kit. Those who have ridden it, what are the differences that you feel over a revalve and re-spring?

This topics been beaten to death for sure but for the average joe a-kit wouldn’t be worth the money. A-kit will literally do everything better than stock if, and it’s a very big if, it’s set up correct for you. With that said, I’ve seen pros ride stock suspension faster than anyone on this board can ride. If you have an extra 7-12k(depending on brand) laying around go for it. Showa a-kit is by far the closest you can go to the pros and it’s over 11k.

You don’t really appreciate how well a well set up A kit works until you over jump to flatland and 1. It doesn’t hurt. 2. It doesn’t bottom out. 3. You don’t crash or get squirrley (I don’t how, but I’ve seen it happen a few times). I’ve ridden revalved stock stuff that is way better then stock, and then there’s A kit stuff which is a step up all the way around. I don’t know about the Showa or KYB stuff, but the WP stuff the fork legs don’t taper like the stock AER forks do, which stiffens the flex characteristics of the bike and improved the handling.

I cased a big double as hard as I’ve cased anything last weekend and I was really happy to have cones and an Ohlins shock. The AER’s would have been rough.

I’m not all that fast anymore but well setup cones are noticeably better

If you've got money to burn, spend money on a personal trainer, a riding coach and consumables like tyres, oils, filters etc and ride more. I'm also in the camp that you don't need A-kit suspension. Sure it looks cool, but unless you're genuinely pro-level speed you do not need it. For the average guy who has shelled out huge bucks for A-kit stuff I reckon there's one hell of a placebo effect going on as well. Regardless of which forks you're talking about, Cone Valves, Showa or KYB A kit, they are all way stiffer with much different flex characteristics, and you need to be charging stuff super hard otherwise it's just going to be beating you up and adding to any arm pump or fatigue that you get.

What makes these setups so expensive? Mostly the materials used?

That couldn’t be any further from the truth lol.

I run KYB A-kit (psf1 air on the fork side) on both my bikes. 2020 KTM 300XC (hard enduro and single track), 2022 Honda CRF250R (moto/GP racing). I bought my first set through Enzo in 2020 on a yz250f I had. After experiencing that I had to do the same to my KTM.

Also thought i'd address the above post saying its "way stiffer with much different flex characteristics". It's completely how you want it. I custom build my forks for hard enduro and single track use, which means i want flex. So i had Enzo build them using kashima coated WP upper tubes, and DLC coated WP lower tubes. Why? Because ask them they will tell you those tubes provide much better flex character versus the KYB version. Then they put KYB PSF1 internals and lugs on them.

A-kit is amazing it is supple whether I am going fast or slow, it somehow makes small bumps just go away, with air especially, you aren’t going to bottom the forks out even when way way over jumping something. Not to mention how much extra traction your front end has through corners.

And people who say unless you are a pro you won’t notice much or it’s placebo to the people who own it. Everyone I let ride my bike to try it isn’t all that excited until they come back. Then they hop off and they can’t explain how much better things feel, they can’t describe it.

Now A-kit that isn’t setup properly for you won’t be any better and potentially worse then stock.

I’ve only own the KYB variant so I won’t speak on other brands. Unless you have owned it yourself, don’t speak on the subject there’s just way too much false info out there about it.

After having an elbow reconstructed, I can say a well setup set of cone valves are the best thing ever invented. I've recently gone back to revalved AERs and its crazy how harsh they are. I definetly feel sore at the end of the day.
Plus I like the look of cone valves, makes me feel like I'm somebody LOL

What I said is absolutely true. What you've posted is what couldn't be any further from the truth. A-Kit suspension is not some amazing suspension nirvana wonderland. Stop talking bullshit. And it does not make small bumps go away. Put you and your buddies on blind tests with a range of forks and suspensions and I'd bet $1000 you couldn't tell the difference between factory a-kit stuff and revalved stock stuff. And yes, I've done plenty of laps on A-kit stuff, with a set on my 22 Honda 450. I'm well aware I don't need it and honest enough about it to say so.

Kit suspension in KYB and Showa’s case is insanely close to production now. About three years ago Showa’s new production fork and the kit fork were basically identical, they’ve since updated the kit fork a little bit. Hell, HRC went to running the production fork lug. KYB is mostly production components that have been coated and a couple pieces added, such as a 18mm shaft (if you get it from Enzo, I believe Technical Touch’s stuff is still 16mm shaft)

WP is a different world, the kit suspension they offer is a different system basically.

In my opinion, most kit suspension is a worse value than it was 10-15 years ago. They cost a lot less then and were a larger difference than production sets.

The couple components you see in kit KYB or Showa that increase bottoming resistant, speed sensitivity, etc such as spring tubes or more aggressive spring seats, can easily be added to production suspension.

Kit suspension isn’t magic. An off-the-shelf setting in Kit stuff has a very high chance of being worse than a production set tailored to your feedback.

This is a topic that could take a lot of explaining when it comes to each brands offerings and how different the fork and shock are separately to the production components. The prices also vary a lot. Kit Showa suspension is quite a bit more expensive than WP or KYB (close to double).

The guy tuning it and your relationship with them / your feedback is by far more important.

One last quick comment. I personally feel like kit suspension holds its most value to the user if it’s a system they prefer. By example for my team in 2021, we utilized KYB PSF1 forks. The Honda CRF250R of course comes with Showa stock but I have a lot of belief in that KYB system at the pro level, namely Supercross. So we leased a batch.

I have a better personal feel with KYB’s systems so I would lean towards a kit option if the bike I’m spending time on doesn’t have that brand stock.

It would be awesome to see a detailed test of the various kits vs revalved by a good tuner. Maybe a project for Keefer?

He’s done stuff really close to this in some recent podcasts.

If this was true then you wouldn't see so many people running it for extreme enduro.

Sounds to me like you bought your A-kit from someone that doesn't have a lot of experience setting it up or you haven't been very good at communicating how you want it setup.

I don't own "A-Kit" myself but I have a lot of friends who have WP Cone Valves, mostly off roaders, and none of them share the same opinion as you and having ridden a lot of their setups I don't agree either.

While A-Kit is very nice and awesome when setup. Dont sleep on some of the other systems out there. Rode on some MX Tech Luckys gen 1s that were a little over sprung for me (me being 155 and sprung for 185). Actually incredible on the bump absorption and big hits. Just my experience

I bought KYB a-kit a few years ago for my KX450. All I can say is that it is 100% better than any other suspension I have ridden in the last 20 years (with revalves from every major tuner and many local tuners) on CRF, SXF, and KXF bikes of mine.

The initial fork setting was too stiff ( was not using the bottom 2-3 inches!) but it still felt great compared to my revalved stuff and I just waited until I had 20 hours or so on the forks and then sent them back to Enzo to revalve. They nailed the revalve and the forks are just magic. That's my only way to describe them.

On the other hand, the revalved stocker shock (also from Enzo) is so good I can't tell the difference between it and my A-kit shock.

Could I ride with revalved stock stuff - you bet! Do I like the A-kit way better, yes I do (forks; I am ok with the stocker shock)! I've never had better forks. I thought I had ridden really well set up stuff that I liked a lot until I got this set.

A comprehensive notes list and a good relationship with a suspension tuner will get you 90% of the results at 10% of the cost. Is $10k worth of suspension going to be better than the stuff the bike shipped with? Absolutely. Is it worth it? That’s really for you to decide.

Imo the benefit of A Kit depends tremendously on what bike we are talking about, and which A Kit setup. The stock stuff on current Japanese bikes and TMs is really good and the delta to kit stuff really small for my vet A purposes. The stock stuff on anything from Austria ranges from mediocre to abysmal. Bone stock my Husky rear shock would fade and get super sloppy. The AER forks did better than the shock for me, but occasionally give a weird rebound and are just harsh enough that I hurt at the end of the day. A kit KYB forks and a trax shock make a world of difference for me. If that stuff were not available I'd have sold the bike.

Kit suspension is cool, so if it makes you happy, then it's worth it.
