I have a 03 cvo roadking and i wated to swap front wheel to a 21in from the stock 16in..how much will my ride change?..is it recommended to lower the front end by 1 or 2 inches to try to get back to stock geometry?..i did the math..swapping my 13/90/16 to a 120/70/21 will only raise my front end height by 1.43 inches..

 

I just installed over the winter a 21"DNA on my 04 RKC. I also went ahead and installed the progressive mono tubes as well. I went with the 2" drop on the front and I'm running 11" bitchin bagger shocks on the rear. I'm about 5'7" and I love it! I didn't want to raise the front end at all with that 21". The monotubes ride like a dream to me. It's a firmer ride but comfortable to me.

 

"Need help with rd 21in wheel"



Does "rd" stand for round?

 

i know..i meant rk ..my auto correct...

 

Your a little high on the increased height effected by the 21" but close, the 21" would be 27.6" tall and the 16" would be 25.2", which is 2.4" difference or 1.2" higher off the ground. Anyways, a 1" drop should be good for getting close to stock ride height, if that's your intention.
