When I am out riding I requently get a feeling like I am ridding over very very small rumble bars. (You know the bars on the side of the road or to warn of an upcoming stop).
The sensation is not as profound as actually riding over them but much more subtile and it is the only thing I can think of to descibe what is happening.

This happens on smooth roads, in just about any gear and just about any speed if I give it more gas and speed up it goes away but with then sometimes creep in once at the new speed.
I do not think is tire or road related. The vibration seems isolated in the motor area and it subtile. It does not always happens when I ride but usually does.

Its hard to take it to the dealer and see if they can feel it because you have to be looking for it and it happens sporatically, sometimes after riding for 5 minutes some times after 2 hours. Some days not at all and some days will happen 6 or 8 times in one ride.

Anyone else experience this? This is on a brand new 2010 Road Glide and I have noticed this since the bike had around 150 miles on it.

 

While your description is quite understandable, that's gonna be a tough one to diagnose...
