Until 2011, it had been over35 years since I had a bike and I could not decide between a dyna and a fat boy. Cranked a fat boy then an fxdc. Without riding either, my decision was made. To net it out, the dyna feels like a motorcycle should and the softail does not in my opinion. I love the shake at idle.

 

Gentlemen, your comments answers my burning question to myself. If trading my dyna to a heritage softtail is a good idea. Standing just 5'5" tall and 165lbs. Heritage's low seat height, cushy ride and its vibration free has attracted me to it.

 

My sig bike is a prime example of that; smooth idle, but past 3K rpm it starts to vibrate to where there`s a slight buzz in my mirrors. The Dyna I traded the sig bike for was smooth as silk past 1200 rpm.

 

You can make that happen!

 

Then you need to re-read the comments here, because what you just said doesn`t make sense.

 

Maybe HD can also hide the suspension on the dyna while they're fitting a balanced motor.....

Oh wait

 

The A motor vibrates a lot more under 2500 rpm. The B motor doesn't vibrate much down there, but vibration increases with the throttle opening. The swingarm with the B motor is mounted directly to the frame, with no rubber mounting to damp the power pulses delivered to the rear wheel.

The rubber-mount unbalanced setup is quite a bit smoother at high throttle openings on the freeway, like when accelerating, or driving over 80 (as long as you're over 2500 rpm).

 

If you want a balanced motor...go buy a softail.
