The 21" is a no brainer...

that's a tough decision you ride looks great. i have been hamering the thought of a 21 on my bike for some time now. have they came out with a 21 inch tire that will fit with out pushing it to the max, any one know

 

haha yeah, find me one dude on the boards who stuck to leaving well enough alone.

 

im runinng at 120 www on mine

 

I dont know bro the 18"s look clean but if your not sure get that heritage fender on there and then see if you like the look i think it would look sick

 

I think a 21 will look awesome.

 

21 for sure.

 

i would leave it alone , your sig pic does your ride no justice

 

Yeah, I got to change it with an updated one.

NIKON, they make a 140x21 now which is what I'd go with. Same size I run now, just in a 21" version.

 

I like the fat tire look myself. I had a Fxstc (stock is a 21 inch wheel)and put a 16 inch on the front end as I did not care for the "skinny" tire look.
Everyone said it looked much better with the 16.
