I'm working on the same thing. The 90 series tire as I understand is the max size to fit the stock rim safely. The Avon 90 was a big improvement on grip over the stock Dunlop. To go to a wider front I'm looking at the Magnum wheel (21 x 3.5) vs the stock (21 x 2.15). Still trying to confirm it will bolt up but appears that it will to the 2011 at least. As I find out more I will keep you posted.
Thanks, keep us posted by all means, but I'm happy with the fat 18 incher myself, it was in my budget cos I scored it for a lazy hundred bucks with a brand new E3 on it too!
And I like the handling as in it dont follow grooves in the road or tar-snakes or wooden bridges like the tall 21 incher did.
21" front wheels are all about the traditional chopper look and I'm more concerned with performance and handling than looks.
And I run on a tight budget its the only way I can keep the many toys that I own.
Magnum wheel should also fit as long as you use your axle and spacers and the axle width is the same.
Ive discovered Victory actually went to a "wide glide" look with wider triple trees and fork spacing on cruisers, at some stage after my 2010, but at what year it happened I dunno.
And what really surprises me is there was no announcement of this wider front end, I'm actually amazed the overactive advertising gurus missed it!!!
Anyway it happened so look out for it, your tape measure is your friend
