Will the balanced motor last longer than the unbalanced?

    I have an 09 Deluxe and was wondering if the balanced engine has a longer life span than the unbalanced. I know there is more complexity and a slight loss of power but it seems to me that the smoothness must account for less stress on the engine and also be easier on the rest of the bike. I am assuming that there are less problems with parts being broken from vibration than say on the Dyna's. Am I all wet and what do your experiences show you?

    I think the balanced engines would last longer too. Looks like less vibration would be lots better. Bet they are smoother hiding, never owned one but would like to.:D

    Normally you can expect about 50% life compared to a unblanced engine. This is worth it because you gain 50% in life in your hands due to the lack of "hand shake sydrome". :s

    Just a theory but....

    When you think about it, the life of the engine just may be the same. The reason I say that is because a HD "balanced engine" is not really balanced. It's is an un-balanced motor that artificially made to look balanced by a counterweight. The stress and imbalance the crankshaft bearings feel is all still there. It is just being hidden. A truly balanced engine is Not the same as an imbalanced engine with a counterweight to make it look or feel balanced.

    Two opposing imbalanced flywheels with their imbalance out of phase by 180* would feel balanced when spun, but the pillow blocks used to support the flywheels would still get chewed up in a hurry.

    I wonder why HD doesn't put the balanced motor in their top of the line UC?

    Because then you would think you were riding a goldwing. No one believes me but were are paying extra for the imbalance, the Potato, the vibration, a 5,500 redline, and Yes the Clank of the tranny. :p

    Absolutely!.. And I think that is why we are all here. If I wanted a sewing machine I would have bought a Singer.
