I have read hundreds of threads. Yes/no too many conflicting opinions.

13 SG moving to a 21/17.

Lower the front or keep it as is? I have no issues touching the ground, I am 5"11. What did you do and how is it?

 

Lower it. 21" wheel raises the bike. I did 1.5 front and rear 1.5. ended up almost level. about .25" higher in front. 3000 miles in 23 days. rides good.

 

I went with a 21x18 setup and did not lower it as I am 5'11" also. If you were a shortie, then yes, lower it. But no problems leaving as is after the wheel upgrade.

 

Unless you like the "raked" look of the big wheel baggers, then lower it & level it out.
I like the raked look but dont like the way it handles
Personal choice

 

I would lower. My 21" and 17" wheels are on order along with the Progressive Monotube (lowering). Harley has engineers design the bikes for a reason. The ride height and rake is engineered so the bike handles well and performs safely. That is my opinion.

 

mine is lowered with 21/18. Rides well and looks good and better with shocks aired down...

 

lowered mine like the look rides great only lowered the front progressive drop ins
