I've had my 2020 R9T Pure over a year now and have put 12,000 miles on it. I've also been an avid forum member here since buying the bike. Both my personal experience and my knowledge from reading tons of posts leads me to believe there are no common issues or problems with these bikes. Yes, some bikes use a little oil, especially in the first 10,000 miles or so. Mine has, for example, but it's a negligible amount. Check your oil every week or two and top off if necessary. Otherwise, I just haven't experienced or read about any problems common to the R9T and its variants.
Having said that, there are some fairly common gripes, suspension being one of them. But in my mind these aren't "problems," and they aren't universal, as some people are fine with the bike as-is. And the parts they don't like, they mod, like I did with my suspension, mirrors (added extenders), and the stock seat (swapped for a Sargent).
By the way, when you have a moment it would be great if you wrote an introductory post in the forum's new member section!
