I think that is very cool of harley to do. I will be doing a 21 on my street glide next summer.
Don't give them too much credit on this one... i'm PRETTY sure this was not their intent..especially since they introduced it for use on a softail..the 2013 CVO Softial Breakout....
But we do get to reap the benefits....
i gotta imagine that with the relatively few softail breakouts to be sold, that most hd dealers are not gonna have a large stock of this tire. just my thinking anyway.
Just ordered one from my local dealer. Gonna send to db to make it into a ww then wrap it around a mammouth 52 spoke rim. Hopefully this all goes smooth...
stock 130/70/18 = 5.1 wide x 25.1" tall
custon 120/70/21 = 4.7 wide x 27.6" tall
new 130/60/21 = 5.1 wide x 27.1" tall
so a 1" fork drop would put that Bagger right back to stock height
well as i said earlier /\/\/\/\/\ based on the numbers the 130 / 21 has an overall diameter almost EXACTLY 2" more then stock..so your fornt end will be 1 inch higher.... does it really casue "problems".... i guess it's all subjective... the bike being higher in the front isn't really popular with most guys... it can cause the bike to feel a little more top heavy..and it can casue sort of an "up hill" feel for some guys.....
but as far as "problems"... i'd say nothing castrophic.....
I been toyin with the thought of doin this to my 11 SG but I dearly love the rock solid feel of the front end on this bike any thoughts on a change like this and how it would change that?
