heres mine im fitting and sorry its not a good quality pic as it was on my cell phone
20 yr old wheels and still brand new till now lol

 

Before you buy your 21" wheels ask yourself these questions:

1. Do I want to lose the white wall look of the RKC? You can get white walls with a 21" wheel but it doesn't look right in my opinion. I'm guessing you bought the classic because you liked the retro look - this will change that look.

2. Find pics of a RKC with a 21" front wheel and windshield before you make your decision. Might not look as good as you think.

 

if you look in the pic you will see the mag wheel in the background and thats what its running on already with no thick white wall tyre as suggested only the pinstripe thin one with a polished and black mag wheel and one of the changes is to get the shiny big look and its not stock already as done a lot of changes and dont ride with a screen at all
and i like being different too lol

 

come on guys i would love to see some 21" on some rkc please and hear your storys on how they compare

 

The 21 on my RK is dynamite! Love it, no worries.

Stock front susp. and 1" drop blocks in rear.

 

well i have fitted the 21" front wheel on my RKC and she handles awfull around town, feels like she is wobbling and tracking on the road through every crack and slight crevise
i love the look but the ride is not very good at all but i will keep her with the 21" and see if i get the hang of it all

thanks again
