    got it, thanks. I thought maybe it was an issue with the weight of the AT compared to what they may have been designed for, say like a CRF 450X or similar. I have one and beat the snot out of it with no fork issues. or any other issues for that matter.

    I reckon they just rehashed the CBR600 fork internals with longer tubes...look very similar...

    Very similar internals to early 90's cr125,250,500.
    Wear parts are common to them and many other Showa shod bikes.
    Outer tubes look nothing like MX bikes I quoted though.
    The 20mm cartridge they use has parts interchangeable with many bikes.

    This is where we disagree. Many thousands of ATs have been sold but the number of reported cases of stiction — which prompted those owners to inspect their forks — is still a tiny percentage of the total. So while I acknowledge there is a possibility that my bike one day might suffer the fork problem, I don't feel I have to pull my perfectly working forks apart now to state that they are working perfectly.

    That's your perogative, just like smokers aren't required to get CT scans. Just don't go around telling people they shouldn't check their forks because you don't want to check yours.

    Would it help both with diagnostics and getting Honda's attention to send the fork oil you drain out to an oil analysis lab? This would also document things for a warranty claim maybe.

    I never said people shouldn't check their forks. I said I didn't feel I had to pull mine apart and inspect them before stating in this thread that they're working fine. After 22 years of riding daily and owning about 60 bikes, I can tell when forks are functioning properly.

    As far as I can tell the OP of this thread did not and does not own an AT. The only thing this thread is doing is chasing its tail.

    Ladies and Gentlemen, STOP!

    If all you want to do is poke someone else with a sharp stick, then post elsewhere.

    The facts are these:
    The Africa Twin is a popular new model bike.
    The bike has forks.
    Some people have experienced "unusual" wear in their fork internals.
    They want to alert others including the manufacturer to a potential problem or issue with this wear.

    That is all.

    No one cares about your opinion as to whether or not aliens landed at Area 51, or ANYTHING ELSE!

    Try decaf coffee, or prunes, or midol and get on with your lives.

    Many of us look at potential problem threads like this as a learning experience . . . PM'ing ideas etc.

    I would clean and wipe down my mountain bike fork tubes after every ride with silicone lubricant as a precaution . . . I have had great success with this prevention etc.

    Nothing wrong with fork tube PM ideas.

    Easy now partner, just trying to lighten up the doom and gloom that a few guys have over their forks.

    For those of you experiencing the stiction, have you thought of spinning the tubes to see if that helps?

    Several inmates have tried it and it hasn't helped. The result is that now you have two wear spots on each fork leg.

    I will share my new plan:

    As I stated before, I am out of warranty. I am going to pull the forks this winter and send them and the shock to a suspension shop for evaluation. The stock stuff needs some valving and spring work anyway (read here that I am not a petite fellow). If the shop and I feel that hard anodizing and full service is the best course, then that is the approach for now.

    As I have stated before, I'd like to retain the dual brake setup, and the modified low front fender. Given that currently there is no attempted swap for that condition, I will research if and how to do that.

    Time will enlighten us all on causes, remedies, and long term results of those remedies. I look forward to the sharing of information.

    I will not be waiting for a remedy from Honda, I've got some riding to do on a bike that I enjoy.

    I don't own an AT. I'm just hanging around and doing my research while I wait for EICMA. If no fix for the fork issue is found and/or if something comes out that fits my needs better then I'll buy something else. Otherwise there's a dealership near me with a leftover 2016 with my name on it.

    Due diligence. Exactly what I should have done before buying an AT.

    Always a good idea to research bikes . . . everyone has different opinions.

    If the CB5X in your avatar is yours . . . the AT will feel HUGE in comparison :p3rry
    It will definitely give you more leg room!

    As mentioned. . . most issues can be sorted out with all the help of fellow riders.
    If I rode much off road, I probably would swap out the stock oil seal to a SKF (due to the problems noted in AT suspension Threads). Similar to swapping out the 950 Adventure red WP seal to the gray upgrade seal before the pump shaft is worn. For now, I will keep my fork tubes clean and lubed.

    "SKF seal kits consist of a new oil seal and a new dust wiper. SKF’s self-lubricating rubber compound not only enables them to keep the oil in, but to reduce static friction (stiction) by a significant amount. Less stiction means that the fork moves more accurately over small bumps and light loads–when stiction is at its greatest."
