changed mine at 45k. You need a very strong {good} , socket style long Allen wrench to remove drain plug. then switched to PMT

I have no plans to ever change it unless I'm doing something else to the forks. I can't imagine what whould ever happen to the oil to need to change it.

Honda does not have any "recommended" service interval for the fork oil. I changed mine when I upgraded to Traxxion springs at 54K miles.

In the first 120,000 miles I replaced seals, bushings and of course, the oil a total of 3 times. All three times were necessity, blown seal, installed original PMTs and replaced PMTs blown out by severe pot hole impact. Based on my repeated observed bushing wear and filth in the oil, I set a reminder to service mine again in another 30,000 miles. Coming due in 2,400 miles.

So based on my observations, I would say about every 30k.

Mine doesn't get changed unless the tubes need to be taken apart for some other reason like seals, the first time mine was changed was at about 120,000 miles. I've also quit using the expensive fork oil, I use synthetic automatic transmission fluid instead and other than fewer leaks I haven't noticed any difference.

I certainly agree with several above. I am now at 107,000 miles on my 2012. It has never gone over 30,000 without replacing the bushings. I installed the full Traxxion front end including the AK20s at 95,300 miles. There is something "odd" about the left fork. I know the "standard" OEM setup is different between the left and right side, but at 22,000 miles, my anti-dive was disabled and my first set of PMTs was installed making left/right side action "almost" identical. Anyway, the LEFT side of the bottom portion has significant "wallowing" and shows significant wear. You can shine a light down the tube and clearly see the wear. I'm a firm believer that the bushings/slides should be replaced around 25,000 a 30,000 miles. I really need to replace the left bottom portion of the left fork at my next maintenance. The right one just doesn't show the same amount of wear. maybe most of the wear happened before I disabled the anti-dive???? Traxxion recommends maintenance to the AK20s around 20,000 or so too I believe.

And, just as important, don't forget to change out your blinker fluid at the same time!
