"certain vibrations! are good for the couple ...!High frequency vibrations are not uncommon for a 4 cylinder engine but they are currently not a “problem” or as noticeable with every 4 cylinder bike. Especially the bigger touring models are often much smoother than for example the little CB650R. With the short gearing of the CB650R, you are much quicker in the high revs and on this bike you feel it in the handlebar, seat and foot pegs. That said I only notice the vibration between 5500 and 6000rpm in my handlebar, I just don’t stay long in this rpm range 😁. Swapping my stock exhaust for a akra did not change anything thing for my bike (no more no less vibrations). I didn’t tell my wife that there are vibrations in the seat 😂😂😂😂
They particularly bother me, I have peripheral neuropathy in the limbs ... hello.Mine will buzz a lot too, (CBR 650R). I thought it was weird at first, but I am used to it now. I would not worry about it. It does not buzz at 11k btw... lol only in those ranges, that were mentioned above.
