Start feeling vibration at 65mph

Went for a ride today and got the bike up to 65mph. I don't notice any vibration in the handgrips at all when I ride, but as soon as the bike hit 65 I started to feel a vibration in the handgrips. Nothing bad, but as soon as I dropped back down to 63-64 the vibration totally stopped. The road was fairly new and smooth. Is this normal for a 650 cruiser?

That's normal with most bikes. I assume you're in the final gear?

Is it really bad? Does it feel annoying? Or are you just aware of it?

Most inline fours have a buzz point where you will feel this vibration on the road. Some buzz quite a bit and some barely noticeable. Have you gone faster than 65mph? If nothing is wrong, the buzz should go away when you pick up the speed a few mph same as it does when you slow down a bit.

Just travel a bit above or a bit below the buzz point if you find it objectionable. If you really want to travel at that speed, a sprocket change will move the buzz point if that's a chain drive bike.

The vibration is not bad, just noticable since I get none at lower speeds. 65mph is my max speed so far. I figured it was just a natural occurance with the engine but it never hurts to ask the experts since I'm still learning.

I'm no expert or anything close, but vibration is totally natural. And I believe vibration starts at lower speed with smaller bikes and ones not design to go as fast.

different parts of the bike will vibrate at completely different speeds. in this case, something is creating vibrations at the same natural frequency as your handlebars. this can be caused by anything from engine revs (try the same speed in a different gear) to road surfaces (go elsewhere)

I've found my V-Star 650cc vibriate a lot at 60mph then the vibration will get less after I pass 70mph point.
