Hi Dirk,
I've had my Ace Bars on for about 2yrs and have not experienced any vibration, the instilation was very straight forward, and all stock cables fit perfectly.
I did experience a bit of discomfort in my palms for the first couple of times I rode in this new aggressive riding position.
Around town at slower speeds your weight is on your wrists, however, on the open road and in the twisties at speed every thing is fine. Just be aware that this will be a very different feeling from stock bars and may take a bit to get used to.
If you have sat on a Thruxton, in comparison, the Ace Bars would be a little higher and slightly further forward than the Thruxton clip-ons. I have my bars set up so the 'U' section of the bars, when looking at my bike from the side, are at a 90 degree angle to the forks which gives me good leverage for counter steering and it also ensures the bars don't hit the tank on full lock.
