recently bought a CB1100EX 6speed that had just been run in.

I really like the bike in all respects and it seems perfect for my needs.

Except, on my bike, the constant vibrations/buzz in the midrange (from 3K to 5K) are intensely intrusive. To the extent that on a recent 3 hour run, my hands and feet were buzzing for several hours afterwards. I was wearing full riding gear.

I have been riding for 20 years, everything form old brits to racing ducatis with many guzzis in between and a fair few inline 4s. My daily round town ride up until now has been a 1970 Triumph twin and that causes me no problems in terms of vibration! (I mean the thumping vibration is there, but it is transient, unlike the constant buzz on my new honda) Heck, I've been using a 1960s guzzi police bike for the past 4 years for my long distance work.... So I don't believe I'm overly sensitive to vibrations.

I use a motorcycle as my primary mode of transport and ride far and often.

There are a few others who have complained about vibration on this forum and many who haven't, what I'm trying to figure out is whether my particular bike has a fault or if this is just a characteristic of the model.

Do you all just keep the revs under 3k?

Does anybody out there have a bike that is smooth between 3K and 5K?

Any info/data points gratefully appreciated

Ride safe,

Ride safe,

Probably not related, but I bought my bike brand new, and it had a strange vibration (not a buzz: a vibration). The cause was a bad set of tyres: both from and rear were out of round.

Make sure that your problem it's not speed related, but rpm related to rule this out.

Nope totally stock... The bar end weights are properly attached

(I checked after the screw holding the right bar end weight backed itself out on a ride!)

No engine bars, all the mounting points seem secure

I have these on order...

I also wanted to say that the stock Honda bars and the anti-vibration weights are of a very impressive quality

Very interesting...

Lets share notes?

Did you get yours new? Or low mileage used?

Will get to checking my chain tonight
