Those numbers seem to be lacking compared to what HD is claiming. Thanks for the information.

Those power numbers aren't that surprising. Still heaps better than any sportster engine of years past.

Interested to see if the power plant remains the same or if it gets detuned for the following sportster models.

Seems legit to me. Harley is measuring power at the crankshaft. These are at the rear wheel.

Fashion over function. Hope they sell a bunch of them, not my taste.

I'll stick with my 65 hp iron.

Is there a calculation to get from the crank to the rear wheel? My hammer bike gets 112 to the rear so I am wondering how the MoCo would advertise it if they built it....

Get the numbers, do some math. The difference would be an approximate % of the loss.
