I too just recently began to run into this issue. In my case I get the vibration through the steering wheel only. I bought new Motivos thinking it may be the stock Pirellis, however they didn't resolve the issue and would keep losing balance (balanced about 4 times). My mechanic thought the new tires may be bad so we replaced them. Balanced them and sure enough the issue is still present. Wheels look fine and I've had another mechanic road force and balance as well with no luck.

Did anybody ever get their issue resolved? If so what was the fix? I'm still getting steering wheel vibration at around 60 MPH with it clearing up after about 70. Interestingly, I've noticed you can easily reproduce the issue if I accelerate fast to 60.
