Has anyone ever had an inflated 16 x 3 rim with 140/150 tire and put it beside an inflated 21 x 3 rim with a 90-90-21 tire and compared overall height? reason im asking? I wanna put a 21 on the front of my 2001 heritage but i cant see how its going to sit level. If you drop the front and rear 2 ", doesnt the front still sit higher?. thanks, Wayne

 

Nope, bike sits pritty much level and i have the 120 upfront

 

Dont get me wrong, your bike looks very nice but it looks like the exhaust slopes downward gradually from the head to the tailpipe. Or maybe its just the way the bike is sitting in the pic.

The reason i asked was i see some that look "level" and some that dont. Is there a method to all this? or just slap the 21" on? Thanks for the response.

 

I went through all that last year with my Nightrain and at the time had all the measurments figured out.
Not sure if this will help but here are some pics:
First one is OEM 90/90
Second is the 16" fatboy wheel
Third is 21x3 with the 120 tire.
