I thought they had the same engine?
Why on the Harley web site does it post three different torque values for different Dynas?
91.0 ft. lbs. @ 3125 rpm
92.0 ft. lbs. @ 3000 rpm 92.0 ft. lbs. @ 3500 rpmAre they tuned different? What's the deal? Why does the SB only put out 91 ft/lbs while the others 92? And why is the lowrider doing it all the way up at 3,500? Does that mean the LR is a higher reving engine in general? But they have the same engine and tranny... What's the deal?

Doesn't matter. You'll buy the bike, change the A/C, fuel management, pipes, and whatever else, and all those stock numbers will go out the window.

I think someone on here had explained that some of Harleys engines have counterweights that make them run smoother, but lose power due to added weight spinning on the crank. I don't know much about that though obviously!
