Buzz after 90mph?

[1299]

Ok, I think I have stock gearing and I know I have a stock tire. At 85mph, the bike is doing 4500rpm. If I increase speed to 90mph, I can feel a vibration in the footpegs. It is very noticeable. If I reduce speed to under 90mph, the vibration disappears. Any ideas? I know, I should be going slower but on some of these Chicago hwys, if you're not doing 80, you're getting run over.

Does it go away after 90


and How old are your tires

every engine has a resonate range where there is inherently more vibration. You just found it. There is nothing wrong with your bike.

I have the same thing. At 4500RPM, there is a noticeable buzz. Happens in all gears, it's RPM based. I asked about it too and it's normal. It's your bike's way of saying "ooh! Time to play!"
