Those were probably harleys ...
One should keep in mind that a lot of the Harley owners tend to beef up their engines by doing some motor work ... heads, big bore kits, etc so ya, buddy has 120,000 but he's done a bunch of motor work... was it needed to get to that?
There are a few Vic owners reporting over 100,000 and no issues but these bikes are too new to have a lot of them. There are quite a few tho that are pushing 80,000 without any issues. All a good sign.
What about the old days when we rode the in-line 4's ... all air cooled. I've had a few of them and have put a lotta miles on them, ran the crap outta them ... never an engine problem.
just sayin yanno....
