I wanna get a set of DNA 52's 21/3.5 F
And 18/5.5R. What do I need to make this
Work? Parts? Lower front and rear?
Etc...it's a 09 rkc with abs

 

You don't have to do anything they will fit right on. If you have a 2009 or newer you can put a 17" on the rear and fit a 200 rear tire, it's bad *** looking.

 

17X6.25 rear on my 2010 SG with a 200mm tire... love it!

 

I think you need to tell folks what your bike is to figure out what you may need

 

The 21 will raise the front about 1.25". We recommend boring out the rear two mounting holes of teh front fender to lift it a tad bit to ensure that there is 5/16" of space all the way around.

If you get a wheel that is set up with proper hubs everything should bolt right on. The 18x5.5 will raise the rear of the bike about 1". Many people will lower the front end 1" to compensate for the added height of the 21" front wheel but it is not necessary. If you have questions please feel free to contact us although we do not sell DNA wheels.

 

I have the 21" front and 18" rear on my 07 roadglide DNA fat spokes. If I were to do it again I would have put a 16" rear on the bike, the extra rim-tire height has alered the already over geared rear..

Also my bike had high speed wobble over 80mph, I lowered the front 1" and that fixed the high speed wobble issue.

I guess with a 16" rear the wobble could still happen as the geometry will be affected some, even with the 1" lowered front..

 

But it sure does look better when lowered.

 

Sure does... mine is lowered 1" in front... Arnott Air Ride on the rear.

 

Sorry 09 rkc with abs
Kinda want to run a single rotor.
Great info so far
17" 6.5 sounds good
I wonder who makes whitewalls in that size
I know vee does

 

An 18x5.5 with a 200 tire is usually what causes a high speed wobble. Keep it 180 with 18x5.5 and you will be fine.
