The dealership owner showed me this himself.
He said this feature has been on all HD's for a long time.
To see this in action, the bike needs to be on a lift with the front wheel off the ground.
Turn the handlebars right or left to their limit, let go, and the handlebars will self-center.
It looks cool, but the slow speed steering was to me more difficult.
This was my subjective observation.
Maybe this was the cause, maybe not.
I'm sure Murf will have his $.02 to add to anything I say.
He seems to be the Harley keeper of the faith around here.
Dude, you got seriously snookered by that owner. He must have been one slick salesman in his day. I can't believe he is actually promoting self-centering as a "feature". That is like promoting a bike because it has tires.
All motorcycles are self centering. They have been since the day the first motorcycle was ever built. That is what the whole purpose of caster angle is, or in motorcycle terms, rake and trail. If a motorcycle didn't self center, it would be uncontrollable. Cars self center too, and so do bicycles.
It is nearly meaningless to show how steering centers with the wheel off the ground, unless your intent is to show how out of balance the steering's axis is. It only tells part of the story. A motorcycle's ability to self center is mostly dependent on the force of gravity pushing down on the front tire, and you can't demonstrate that with the bike sitting still.
By throwing off the balance of the steering axis, they have simply deadened the steering. The primary reason to do this is to try and control wobble, but it also increases straight line stability and makes the bike much more civil and easier to ride. From a performance standpoint however, it seriously hurts handling and makes the steering feel heavy. The owner wasn't going to tell you that part. It is not a unique or novel trait. It is primarily an American design attribute that was discarded by the Japanese decades ago.
Sport bikes generally have less self centering capability than other bikes in order to make them feel lighter and more flickable in the turns. When a mfr gets too carried away with it, the bike can become twitchy.
Steering geometry plays a major part in a bike's overall personality and feel. It all boils down to what the designer's intent was. This goes a long way towards explaining why Harley has its own fans and Japanese bikes have their supporters. And it exemplifies why there is not all that much crossover between the two. It all depends on what kind of personality you want from a bike. For better or worse, there is no denying that Harleys do feel different than any Japanese bike, and this is one of the reasons why.
