So im thinkin about pullin the trigger on a 21" on my 07 roadglide. What size rim can i fit in the rear without modifying swingarm and fender ? What size rubber ?

 

Is stock rear wheel 16x3.5 ??????

 

what year is your bike? if an 09 you can run a 5.5 or 6.25" wheel with a 200 rear with out any mods

 

I have a 05 and am running 18"x 4"rim with a 160/60 metz if this helps

 

I have a 2007 roadglide. what size will fit. 18x3.5 or 18x4.25 ? If they both fit whats the better size to go with ?
