I know what you mean, it's normal, and it could be the road in that area. Going to my friend's house, the speed is 50mph, I go about 45-47mph and I do feel the vibration, but it isnt like I cant handle it. The higher the speed, the more you will feel it, the tires are small and arent meant for high speed riding although they can do it. It's just the size.

Check and make sure your front and rear tires are both at 30psi. Make sure when you check it before you've been riding. The air in the tires needs to be equalized with the ambient temp outside.

I noticed something to that fashion, went on for a while as my scoot was getting hot from a mountain climb, thought maybe something weird going on with the piston, I let the bike cool down then got back to speed and it was gone, then later on another climb it showed back.

Mine shows up right at 40 mph

Its the "magic fingers" of the scooter world and you don't have to put in a quarter.

My extreme vibe was due to flat roller weights.

Now that it's gone, i kinda miss it.

I just got mine a couple weeks ago and noticed the same thing. In my case, it's between 40-45 mph and some times the pulsing starts slow and speeds up really fast and varies like that. Talked to my dealer who, just from my description, said it's probably nothing to worry about. Glad to read that it's not just my machine.

Has anyone successfully corrected this? If so, how?

I have experienced this as well. For me, the vibration has occurred anywhere between 40 and 60 mph. From an engineering perspective, I've always considered it bad for machinery to vibrate in this manner. I guess time will only tell if we all have a problem.

I have the same. It starts with a slow frequency at ~40 MPH, increases frequency until ~45 MPH and then reduces until ~50 MPH. I just use it as a speedometer that operates by feel.

My previous engine didn't have this "feature". My guess is that it's some sort of resonance between the engine speed and transmission speed.

Mine does it, too. Nice to know it seems to be normal.

Normal? I don't know... mine doesn't vibrate abnormally at any speed. Except for reasons pointed out here - bumpy roads, under/over inflated tires, etc., my ride is smooth throughout all speeds.

It only weighs a little over 200#

I have it too, although I will say it's something to do with wear and tear...I'm feeling it more at 200+ miles on the ODO than before...
