I traded my 2014 LTD for a new 2015 CVO LTD and I seem to have much more engine vibration but it is only very noticeable when using the rear brake and slowing down from 40 to about 25 mph. If I pull the clutch in and apply the rear brake it feels like a warped rotor. If I raise the RPM or shut the engine off it does not do it so I know it is from the engine. Two dealers test drove the bike and said there is a problem and one changed the rotor. They kept the bike overnight and said the next day it was normal. It has much more vibration than my 2014 and both have linked brakes so that is not the problem. Has anyone else that has changed from a 103 to the 110 found a major difference with the vibration ? Other than when using the rear brake it is a great bike. Using the front brake there is no vibration. Thanks for any replys

 

I get a vibration when using the rear brake as well when slow as you describe but my engin is the 103. I am interested in what others have to say.

 

Mine does it too BUT it didn't start doing it until I jacked around with the engine and motor mounts trying to center the engine in the center of the doughnuts and in the frame.

So self induced in my case. I plan to dick around with it later and figure it out. Probably overly tight belt or something.

 

My 2014 limited was fine.It is a new bike and I have not done anything to the bike. Only 800 mi but I think I will have to figure it out because Harley says it is normal. I know how my 2014 was and it is nothing like this.

 

My '15 Limited Low (103) does the same thing. Took it to the razor sharp techs at the dealer & told them it vibrated so bad it shook the windshield.

They tightened the windshield. Left the brake alone.

 

When I called Harley support and they say there is nothing they can do about it. There is no way to get a rep to look at it.Said there are only 3 reps in the whole country to cover all the dealers and are too busy to set an appointment. This is an eye opening experience for my with Harley. Could be my last Harley.

 

It's normal. I'm not sure why they do it, but all the 2009 and newer bikes I've ridden do this. On a side note, you don't notice it when properly applying your brakes (80% front / 20% rear). I've only felt it when using the rear brake only which I only do when performing tight manuevers.
