Hello Farout
As far as i know all standard cranks are not forged. Forged cranks are aftermarket items
like sceamin eagle, jims,s&s etc. IMO it's the level of work and machining and hand built element that makes them run sweeter.
Where abouts are you in the UK, check out powerglides in kent (aka Boz engneering)

Well, it has always been my understanding that all Harley Davidson crankshafts are turned from a solid piece of forged steel. The difference being that the older models were hot forged and the newer ones are cold forged. That's why they have a different look to the metal. Now looking at the flywheels, it's been my understanding that the stock flywheels are cast. I could be wrong about this but, I do recall hearing a lot about this very subject in the past.

from what I have seen the stock cranks are 2 piece and pined in the middle were the rods go , that is how they sizzor , my 96'' in my Ultra did that , thay can be welded or maybe after market may be one piece if that is what you are talking about

Yes, I didn't mean that the entire crank was machine from one piece. Actually 3 pieces. Sorry for not being clear.

From djl:
"'99-'02 hot forged/Timken, 4.000" stroke
'03-'04 cold forged/roller, 4.000" stroke
'05-'06 cast/roller, 4.000" stroke
'06 Dyna cast/roller, 4.000" stroke, sprocket shaft accepts new compensating assy.
'07-present cast/roller, 4.375" stroke, sprocket shaft accepts new compensating assy.
There was some overlap between model years as it was as "running" change. If in doubt, you can check by removing your crank position sensor and, using a flashlight, look at the flywheel OD. If the sensor trips are machined you have a hot or cold forged unit."

99-02 Hot forged crank ( the best.)
03 to 04 "cold' forged, ( decent.)
04 to 06 first cast cranks ( with shorter 4" stroke "OK.")
07 to 08 (different presses on assembly = junk.)
09 to present ( better presses on assembly = better, ( but I still won't own one.))

Hahahaha. Beat you to it. 07+ junk well a bit harsh but yes. As the 07+ put on some real miles this will come up more but there really haven't been a lot of failures considering the # of them out their.

Harley didn't see it coming either. Lots of "early" guys got brand new motors back then too.
Your '07 crank will be quite stout I'm sure .......(now!)
