    Serviced forks. 10k km.
    To recap, i use the ATAS uppers and lowers with reg AT internals with my own valving specs and springs.
    Didn't need to run shim behind bush, clearance is much better on these fork bits.

    No visible blemishes or wear on upper tube.
    Oil colour quite good.
    Wasn't expecting to see any thing, has been many ATAS forks serviced with no noticable wear at 20k km +.

    Excellent to know that.If mine wear out will do the same as you.Would most likely put new aftermarket internals in at same time.

    Ohlins NIX30 inserts a nice option. Nitron, Touratech and couple of others offer cartridge options too.
    It is possible to convert the oem fork internals to a single function oper leg. The only downside, is for one cartridge, it is not reversible.

    Not thinking a single sided set up is a great idea in such small forks.Seem like you would be giving up a lot of flow on a set of forks that are already wanting flow wise.

    No issues with flow.
    Oem valves flow plenty well enough.

    But if you switched to one side just rebound and one side just compression I would think that would cut your flow in half.I am guessing the one kit you mentioned does that but not sure.

    All those kits do that. Don't lose anything in damping. Makes it better. Proper midvalves.
    Good base valve a must. Biggest issue is cavitation. Not being pressurised like a twin chamber fork for example.
    But can be made to work very well.
    Touratech kit is pressurised, don't think others are.

    The outer tubes on 2020 AT and ATAS are finally the same (surprise-surprise), just different color. In person, they look very similar to 2019 ATAS, but I didn’t compare them side by side.

    It'll be interesting to see if the part is superseded by the new tube...

    Lots of 1100 footage showing the bike bouncing out of hits. Now that I k ow what I know about suspension. I would still get it but order springs and shims the same day

    what problem?? :flush
    But to give them some credit, they are addressing the issue, and putting in better tubes..only time will tell.

    remember...ignorance is bliss.
    here's a refresher for a good laugh from the blog..
    Here’s a hilarious read from one of the Revzilla guys, when they asked Honda USA about the issue, linky here: https://www.revzilla.com/common-tread/you-needed-to-know-honda-africa-twin-dct-crf1000l

    So, parts wise, 2020 both outers almost identical.
    Guts are different from base to ATAS electronic.

    so it's def. a different part number even to the 2019 ATAS...

    I'm curious about what's the 2020 outer tube diameter in its narrowest point. Or may be they just made some minnor change in the inside?

    Did you noticed that 2018 ATAS outer tubes are more expensive than 2020's?

    it will taper from the bell end, and get thicker just before the lower triple. it's not contant.
    Talking to @Motociclo, if manufacturers kept the same thickness as the bottom of the tube (bell end) all the way up to the triple, flex would be reduced by x10 plus.
    Every tube manufacturer does it, to save on material.

    I didn't catch the price. I'm all spent out on tubes.. :D
