I think it will be easier to find something if you tell us where you are.
Hi, im from greece, not around the corner i know
i found yesterday a pair of kyb sss localy but im not sure if they fit cause are from a crf. Either way thx for the response, hope to get more options before i buy

I put a set of Yamaha YZ Kyb SSS on my 06 model. I used the Yamaha triple clamps, but kept the GG wheel. I had to turn some new bushings for the front axle (Yamaha uses a thinner axle) and make a 250mm brake disk. It would have been a little easier if I had used a Yamaha wheel, but as I have my own lathe etc (and have fun using it) I chose that route. it worked quite OK, and surely better than the old worn out 45mm Marzocchi forks.
But as you go from 48mm Sachs to 48mm KYB I guess the triple clamps are quite close when it comes to the diameter of the fork legs. The offset may be wrong (different), though.
There are a lot of old threads here about fork swaps. You should be able to find quite detailed info by searching the forum.

So to sum up its either new kyb aos forks that cost 1350e, or used very clean kyb sss forks from a 2010 crf 450 that i can find on 500e. Crf had 240mm disc brake while i have a 260, so i guess is harder than a yzf that has 250mm. Then its the axle size etc. And ofcourse these ate used mx forks that at some point i have to revalve or even change springs as well. So the cost is increasing. Ive read 30 pages in this forum but still cant find that exact conversion, i meen from crf to my sacks gas gas. The thought is buy the used and when its time for service i revalve and see springs if i can trail ride with 450mx forks until then and not end up with a bike i cant ride until revalving. Amy thoughts? Thx again!

I think 450 MX forks will have too much compression damping for trail riding, but if you take your time and are used to working on bikes, you should be able to do some simple revalving. The spring rate will depend on your weight. With some luck, the used fork may have suitable springs.
Even new aos forks may need other springs and revalving, depending on you weight and ability + the type of terrain you ride. Remember that suspension is a personal thing.
I wouldn't take it for granted that the GG triple clamps can hold KYB forks without modifications. If you are unsure, I presume I could measure, as my son has a 2011 EC200 with Sachs forks (ohlins inserts) and I still have the old 06 EC200 with KYB sss. I can take out my calipers and do some diameter measurements if you need. It may take some days before I can do it.

youve been very helpful already. i service my bike on the local rieju store and the guy who has it is like a friend. so when hes back from vacation hell guide me. i hope to have some feedback next week to share. thx again and i guess this thread can be moved to suspension, sorry for that!

the GG tripples are narrower than yz tripples, which is why some have done a full front end swap (including tripples). There used to be a section on allballs website where you could see what bearings were required to mate the triples to the bike.
An easy revalve is to go with racetech gold valve kit, that is probably an easier start for anyone not versed in the dark art of suspension valving
idk friend i kinda lose momentum as i learn about the swap. 500e for crf sss forks plus mods and parts to fit plus revalving an mx fork for rocky terrains plus used worn fork... kyb aos cost 1350 and are plug and play. the only reason im thinking about used forks is that maybe im not gonna see much difference than new aos because of my sachs rear shock. if i changed both i buy new but i cant right now

I did a racetech gold valve kit in my KYBs on the 06 model. Worked quite OK, but not optimal.
Later, with the 48mm Marzocchis on my 2015 model, I did all the revalving myself (with the help of people on this foum). I got a result that was quite OK there as well. But now, I have started using Ohlins TTX inserts in the Marzocchis on the '15. Works better than my worn and home-valved Marzocchi internals. I did use the Marzocchi internals for approx 500 hours. They now need an overhaul, I think. But as I had the Ohlins already on the shelf, the time had come to start using those.

yep, when i changed the forks to kyb's the sachs shock became the next issue
