I have a 2017 M8 Road King. LOVE the bike, sold my 2007 deluxe and glad I made the change. The bike has been a solid runner with none of the M8 issues others have talked about.
Notorious M8 problems probably affects maybe 2 bikes out of 10,000, or ~ 0.02%.
Harleys recent recall for 2017 and 2018 M8 bikes with hydraulic clutch covers ~178,000 bikes in the US alone.
A mole hill can look big with enough magnification.
I also bought one of the first batch of 17 Road Kings with the M8 and couldn't be happier so far the only issue is not enough time to ride. O and I do check all my oils occasionally and have had no transfer or sumping
15 RGS Here. I bought it 11/16 with 6K miles. I hit 22k today and only issue I had was a head unit replacement under warranty for Bluetooth pairing issues. Oh and a brake fluid reservoir cap leaking which I noticed is leaking again today. In short. I have been pleased. I have no experience with the M8 however a couple of guys I ride with like theirs.
I put 8,000 miles on my ‘17 M8 RoadKing, with no issues. Then I traded it for a new ‘17 leftover Ultra Limited. I’ve had the Limited for 2 months, and have 6,300 miles on it...with no problems.
