How-To/Tech Tips: Air Fork Setup - Vital MX 

This is the first video to do a good job at explaining the sff air forks. Thanks vitalmx!

This literally saved my life I've been looking everywhere for something to explain how these things work. I just bought a 2016 rmz450f its first bike I've owned with air forks and it was giving me a head ache 😂

My dad made and raced with his own air shocks similar to these back in the late 70's and early 80's with his RM250.

how to adjust air forks, remove air fork, install spring fork. done. "these forks can perform well, but..."

I guess this is why there's a lot of dislike for the air shocks, fair bit of mucking around, especially as Honda's one you need to remove the disc brake guard. However they are supposed to be the bee's knee's when setup so whether or not it's worth the trouble is anyone's guess. Only problem I see is that seals with those pressures won't last nearly as long as spring/oil shocks. As Honda's 2018 model went back to springs it makes you wonder if the whole thing isn't as good as they claim.

Thanks for this video. Turns out the dealer reversed the inner and outter pressures on my kawi!

this guys face looks like hes struggling about describing something very simple... LOL

What would be good street riding pressure ? I got súper moto kx450f 2015 an the front forks are low real low

Are you talking lbs pressure, help to be clearer

good video thanks, if outer is not holding air pressure is that a bad fork seal? could oil just be added through the valve if stems re-moved to get the oil in each chamber? Do you ever plan to show how to do fork seals and fork oil change on sff tac forks?

Does this work for the 2016 showa forks on a crf 250?

Hopefully you see this comment. What about the left fork with the 2 flat head screws? Do we just leave that fork alone? Why is there are hard and soft options on the clicker? Do we need to open the top screw to let off excess pressure? I'm new to air forks

If the order is important, is it necessary to zero out all air pressures before starting?

Thanks a lot!!

i have a 2015 crf250r and the my don’t have the outer chamber valve on top. there’s 1 valve on top and then 1 valve on the bottom.

0:50 Completely wrong explanation, understanding how this fork actually works would help you with setting it up immensely, and it's not really complicated at all. Without negative pressure the fork would have a hard time starting to compress That's it, the whole point of this chamber is to adjust how plush you want your fork to be. The progression of the fork is actually regulated by two upper chambers, them being outside and inside have nothing to do with their function btw, its all about their size, the bigger one is same as your regular spring in a normal fork, and the smaller one is an additional tiny spring, pumping it up increases progression, which means the less bumpy your ride is going to be and the harder you going to send the more pressure you want to be in it. Summary 1 inner chamber: main chamber to set fork for your weight 2 negative chamber: to set how plush you want your fork to feel. 3 outer chamber: to set how easily the fork would bottom out basically.

thanks

What would be the best set up for trail riding?

Can u use a Bicycle pump to fill them up?

Do you have any videos on 2017 ktm 65 air forks think they AER 32?

very good the video but could put subtitles in portuguese "Brazil" because we have many bikes that are these models and we don't have much information and with the subtitles in portuguese it helps a lot

Anyone got the ideal settings for an intermediate that weights 62KG

any one know a good pressure to start off with for 210 pound person , Just got the bike and i know the previous owner is a lot heaver guy, Thanks

These things are a pain in the ass, I have a 2018 KX450f and am using the WP air pump and that thing is a POS. If you screw it all the way on it leaks and you cannot get the required 130-150psi in the inner/balance chamber. If you back it off a little it just leaks. Also on my 2018 the inner and outer chamber are opposite of the one you show here.

All very informative but all these videos never explain how to stop the air coming out when unscrewing the fitting or maybe how much extra you put in to compensate for the inevitable loss 🤬

will this air pump work for a 2015 crf250r?
