I let another member I ride with, Herman, try my bike not long ago. His perception was excessive vibration when you get on it. Not so much cruising at 70 etc. I have nothing to compare it to. I do notice the vibration on full acceleration but thought it normal, cause going so fast. He thought bike vibration rather than engine. Something related possibly to motor mounts.
Seems I notice it past 3k rpms.
Any comments,info on this point with your bikes? Thanks in advance!
