Any one know the diameter of the down tube on 2010 SB, I am guessing it is the same as all 06' and newer dyna's but I don't know what that is either.

 

1.25" I would imagine, but I could be wrong. LOL. Not much help, sorry.

 

It is 1.5", but I have to ask why would you not just go out and measure it to be certain and NOT depend on the internet? Sorry to pick on you, but ??????

 

He may not have the proper tool to measure it withor may not be near the bike (blueangel...Air Force, might be off base).

 

Yea, my micrometer is in the cal shop and my eyeball isn't calibrated yet. I figured it was 1.5" but to know for sure.

 

I have an 06 and it is 1.25". Is there a reason you don't go measure yours yourself ? I hate to say this dude, but to ask for info and then bitch about somebody not going to measure FOR YOU is really bad form. Ever think he may not own a 10 Street Bob ? Take a piece of string and wrap it around the down tube, mark where it meets itself and measure with a tape or ruler. Don't need a mic for that as it isn't rocket science.

 

Oh and just so you know I was at work, on my break, and for anyone that serves in the military or works as a military contract company knows, that when you work on a $300 million project, the company tends to not want you carrying their tools out of the hanger and into a parking lot for personal use.

 

Do the newer ones have multiple sizes on the down tubes like the older ones? Mine reduces size half way down.
Best thing to do is measure yourself like others have said.

 

Respectfully.....but you have the time while working on said $300m contract to post on HDF? lol

 

You may have insulted him....His avatar says USMC....lol
