KTM Guy here considering a KX450F. Really don’t want to deal with the air fork everyone seems to hate on it and I was wondering what the best options for replacing it are. Thanks in advance!

Copius pattern amounts of phrases like “Anyone have”..., “Anybody know?”.... and their variations.

Thoughts?
Any help is appreciated!
Thanks in advance!

Find a set of 2010-12 KX450F KYB spring forks and install them. They bolt right on and are the same basic fork as the Yamaha SSS fork, just valved different. Enzo or Factory Connection can valve them if needed.

Take it to the limit, one more time!

You could go the Race Tech fork spring conversion kit, itz like $500 and makes those crap air forks into pretty dam good spring forks! Its super easy to install even for the average weekend mechanic. Its a helluva lot cheaper than buying a new set of forks of any kind. Not to mention the potential for having to buy new clamps etc.

Imo that would be your best most logical option unless you have "eff-you" money and dont really care about cost....if thats the case, just get a set of A-Kit forks from ebay or straight from Showa or whoever is their American importer/distributor brand new.

I gave $600 for the forks like I described above off eBay. They were already done by Enzo and were awesome.

Seems like a solid option, I’ve always really liked any KYB stuff I’ve had on any bike. Did they same thing with KTM actually by going back to twin chamber when they released 4CS. If I end up picking up a KX450F I’ll give it a shot!

The Showa SFF TAC is a great fork when set up properly; even better than the Ohlins RXF48 i tested in comparison. I'm running SKF oil and dust seals, SKF glide kit, and RaceTech gold valve and valving. In stock form i had a traction problem; the fork had a significant amount of stiction and was stiff in the first 1inch or so of travel. After getting it set up like this, it was a night and day difference. I can charge through braking bumps with confidence, point the front end wherever i want to, and have great bottoming resistance when I overjump or case something.

I'm 190lbs naked.

SKF oil and dust seals
SKF Glide kit
RaceTech gold valve
RaceTech valving for intermediate rider
180psi inner
10psi outer
185psi balance

Just make sure you check/set the pressures in each of the 3 chambers with the fork cold before you ride for the day. Its not really a big deal setting the pressures, and you have the flexibility of messing with "spring rates" for free.

BTW: If you get a KX450 and want to get rid of the TAC fork, let me know! I'm trying to source a clean set to put on my KX125 smile.

I had Johnny at TBT racing in Arizona covert mine to SFF Spring forks with all showa components. They work great!

They are not as bad as people say. The thing you will need to do is a significant amount of learning. I am happy with my forks and I will probably get race tech stuff when the seals leak. They are very versatile and can feel very close to kyb

Racetech spring conversion still sucks. Look on Ebay for a set that has springs in both sides. After struggling with them I sold my 17 and got a ktm.

Yeah honestly as much as I'd like to switch it up, the 450SXF has never let me down and I have really liked that AER fork from what I've tried. Hard to change sometimes...

I have a 2017 KXF450 and I love the bike. I couldn't get around to liking the air fork so I turned to PC Spring Conversion. I loved the forks. A noticeable difference in handling. Then I had a wild hair to burn money in my pocket and I am glad I did....I bought A Kit and there is a major difference over the spring conversion...its almost like cheating.

Anyways, look at PC, Factory Connection, or JGR Spring Conversion. I think you will like it.
