Vibration? Off power vibes sometimes from uneven front tire wear due to under-inflation or other causes. Eliminate that first, and also other front end issues, like busted shock, ball joint as these all happen to that model.
If problem persists:
1. Suggest you search on this forum on how to do an informal inspection of your final drive, with bike on center stand, try to rock the wheel 12 and 6 oclock, 9 and 3 oclock, etc. Should be minimal to no play there. Rotate and listen for grinding noises. Drain and inspect FD fluid looking for particles.
2. Additional research will require more $$$ and time, like opening up FD and drive shaft housing, etc.
3. Start saving some $$$ for repairs.
