- Today we look at a quick and easy way to service your SR Suntour Air Fork! In this video, we service the lower legs and replace the seals. Although we're using the SR Suntour Epixon/Epicon, this video can also apply to the Suntour Raidon fork and Suntour Axon fork. It's also recommended that you buy a Fork Rebuild Kit from their website before starting the service.

Wow. Best damn tutorial video EVER. All the relevant info, no extra dialog or super annoying music. RockShox and Fox are gonna send out a hit team to remove this genius from the gene pool.
Thank you so much for your incredibly kind words! 🥺❤️
@@EverydayBiking Thank YOU for not wasting my time. I'd love to see you do a video on X-Fusion rear shock rebuild.
The cinematography and information in this video was fantastic! Thank you!
Thank you so much!
This is the best Suntour service out there - it's correct, it's simple, and it's concise. Thank you! It helped me greatly in servicing my Aion 35 EVO for it's first time.
Really excellent format. V clear with no extra fluff!
Cool! Hi from Bucharest România 🇧🇪
Bet that works like a dream now. A lot of work however, think I'll see if the shop near me does it 🤣
Well that was a brilliant fork service vid! Thanks a bunch!
Very useful!! I am afraid to do it alone.
Too many crucial tools are missing. Let's start collecting the tools..
This was excellent.
Falto agregar aceite en las botellas 15 ml aceite ipone 10w fork , para mayor rendimiento. YO eh agregado el aceite en las barras para una buena lubricacion en los casquillos y menor fricción.

hey there, today i tried to change the travel on my new raidon (gave up because i couldnt get the damn pin out) this video helped a lot to get the lowers off. leaving the bolt in and using a mallet to separate first did the trick. even if i failed its always fun to take stuff apart and put it back together. cheers
Hard to do without a pin punch. Even then it's in tight.
Really clear video, thanks - made servicing my Raidons so easy.
I’m so excited to ride this season everything’s clearing up
i dont mean to be offtopic but does anybody know a tool to get back into an instagram account..?
I was dumb lost the account password. I love any tricks you can offer me.
@Finn Matteo instablaster ;)
@Jamison Felix Thanks for your reply. I got to the site on google and Im waiting for the hacking stuff now.
Looks like it's gonna take quite some time so I will reply here later with my results.
I have the epixon at 140mm as I figured due to me being a feather of a rider it is nice to have that much travel ideally I would've got the Aion but they only come tapered which doest fit my bike. But so far the Epixon is amazing quite comparable to solo air Reba in all aspects.
SR Suntours may not be the best but they're hugely underated!
Is your 140mm still functioning?
@@phil5073 yes. Lower leg service every year, wipe down the stantions after dusty rides saves the seals.
Building up a Santa Cruz Blur 1 classic mulleted with a brand new Epixon 27.5 fork that I have set to 140mm as well - should be interesting to see how it holds up! Gonna shred the hell out of it.
@@phil5073 yeah still works, I have been using it less often than before. But honestly with periodic maintenance it performs like new. Like any RockShox or Fox fork would.
Brilliant. Just what I needed.
Thank you so much! I just tried it on my suntour aion evo and BANG! I felt significant improvement!
This is the opposite of the "dream built". It's the "dream Teardown"
I am looking into doing a lower leg service on my Aion, though i am quite confused about whether i should add oil (which/how much?) into the lowers like on other forks, or not as it isnt mention anywhere. I'd be very greatful for any help/hints, thanks!
Also great informative video!
Typically suntour uses no oil in their forks to make maintenance simpler. However, you can add 10 to 15ml of 3wt oil to each leg. Recommended brand is Maxima Plush Suspension Fluid. That goes for any of their air damper forks to improve performance.
@@EverydayBiking thank you very much! I assume this is also the recommended oil for soaking the foam rings, right?
@@eddynator5847 You could use it yes.
@@EverydayBiking If I'm just doing a lower leg service (don't yet have a chamferless socket), would it be worth throwing in some 15wt oil?
@@mydearriley I probably wouldn't bother. Fork performs quite well without the oil and it just makes the next tune-up messier. Your choice if you want to try and squeeze out a bit more performance.
Obrigada pelo video
the problem is the rc damper, some suntours (like durolux) come with serviceable cartridges and i really wanted to see how much oil does the compression part take, and if there is any hack to do it by eye (like for example rockshox mentions the oil height by saying "80-85mm from the top", sadly suntour doesnt make service manuals like that, even tho some of their fork are sorta pricey and were actually designed to compete with lyrik / fox 36...
me re sirvió graciasssssssssss. Tengo la suntour raidon!
Thank you very much, excellent video, maybe you know if the cartridge of a sr suntour AXON suspension can be maintained?
I was planning on doing that to my bike, going from 100 MM to 120. I might get the little one an air fork, but they don't come in hot pink :(
Thank you!!!!
Greetings from Philippines! Question, can I also use the same 80w oil used in the air chamber for the foam seals? If not, what is the recommended oil weight rating for our Suntour fork oil seal, can I also use the Fox Float Fluid (pillow pack)? Thank you so much, I own a Suntour Axon and Im noob, I'm very sorry
This is just a question. Does the sr Suntour epixon air forks use any type of oil for the lowers? And if they also use the foam wipers that sit underneath the dust wipers? I'm not quite sure if the fork in the video has a similar build than the epixon. Thanks!
Well, while cleaning out the inside of the lower legs a small o-ring popped out (I think on the damper side). It is NOT the one that holds the bottom adjuster nut on, that's accounted for. Any ideas? I've been looking at exploded diagrams trying to figure it out (Epixon)
That is strange. I would not expect a small o-ring inside the legs of the Epixon. Maybe someone serviced the fork in the past and put one inside for some reason. I would leave it out.
@@EverydayBiking I think it's the o-ring that's supposed to be on the bottom of the damper
@@DragNetJoe There is a very small o-ring on the very end of the damper. Normally it does not come off but maybe in your case it did, so yes, that might be your o-ring.
May i know how much oil wt that was included in the kit? Thank you!
10 ml of 80wt oil
The lower thread on the rebound side seems to have been crushed.What should I do?
I've followed everything and now my lockout doesnt lock my fork. any idea?
Do I have to remove the air to separate the lower leg?
Yes
Can you use a degreaser to remove all the grease?
Yes you could.
@
Everyday Biking, how many notches going from 100 to 120mm?
Move up to the next hole like you see in the video for 120.
@@EverydayBiking OK TY
Damper rebuild tutorial next?
What type of oil that you put in the air chamber?
what oil should I use for the foam rings?
A quick question. Can the damper (RL R one) be serviced? The lock out function on my EPICON has stopped working and I don't know why. May be on the last ride there were a few bumps with the lock out on. Any helpful suggestion is appreciated.
The damper is not really designed to be serviced. Suntour only sells a replacement, no parts.
@@EverydayBiking Hi thanks for helping out. But I did service it, basically changed the oil, put it back all together and works better than before! Their 'blow off' feature ensured that the fork was not damaged, only some oil leakage. On replacing the oil to the optimum amount, the lockout function was enabled again and working more precisely than before. All other functions are fine.
Is it okay to put oil in the lower legs like and open bath fork would or will it damage the fork?
You can and it won't do any damage but probably not worth the effort on this fork.
What foam spacer did you use?
The epixon and higher forks come with a volume spacer or you can get one on their site.
Here in Germany people complain a lot about rattling Suntour suspension forks.
My new bike will have a Aion and I’m kinda scared😰
Have not seen that issue with the Epixon. Might be caused by a few things. Loose bolts on the fork bottom or the negative air spring moving around. If you have the issue I would suggest checking all fastners and making sure negative spring is well greased.
I seem to be one of those people complaining; my Aion started to rattle and it was indeed the negative air spring that came loose/broke. I had it repaired under warranty so i can't tell you exactly what the problem was, but i figure if it happens again I can fix it myself
Is this also applicable for the Durolux EQ version?
The forks are similar enough that most of it will apply.
Where did u get the rebuild kit?
Please 🥺 do XCE sr suntour service
I have epicon Air Fork and I need a new seals any leads where can I buy?
You can order parts on suntour website.
I have a sr suntour raidon fork and people tell me it can go up to 160mm travel its currently at 120mm is it bad if i put in at 140-160mm?
I would not go above 130 mm. The fork is not strong and stiff enough for more.
@@EverydayBiking alright thanks, but now I’ve got a new question😅 i was working on my bike and it sat upside down for like an hour after that i noticed my lockout was not working… ive checked the bolts under the lockout cap they are tight but it still doesn’t want to lockout any ideas? My rebound still works btw all though it started making a strange sound
Can I put Superlube Teflon grease on the seal?
Never used it so can't comment.
How often do I need to service this fork
Depends how often you ride and what the conditions are. Once a year is a good idea.
What oil can we buy
You want 10ml 80wt oil in the shock. A quality 80 wt motorbike synthetic gear/fork oil should work.
Bro where is cartridge oil change...
SR Suntour does not give much info on their cartridges and since the cartridge is sealed they don't usually need much servicing. Maybe we will do a video on that in the fall or winter.
No oil in the lowers?
These forks do not require oil. You can add it if you want to.
@@michaelkollmann3197 If I put oil in Epixon, how many cc should I put in left and right?If I add oil, will it improve the performance?
@@user-cj2ok2jm6e check out the comment 7 months ago under Eddynator where adding oil was discussed.
@@michaelkollmann3197 Can you tell me the site?
@@user-cj2ok2jm6e Right here in the comments. "Typically suntour uses no oil in their forks to make maintenance simpler. However, you can add 10 to 15ml of 3wt oil to each leg. Recommended brand is Maxima Plush Suspension Fluid. That goes for any of their air damper forks to improve performance."
