I doubt the 48 does anybetter than the Nightster/Iron at speed. I am sure it does better than the 21" front tire bikes but not the 19".

 

My basis of comparison is the 2007 XL1200L. Totalmotorcycle.com shows stats for the 2010 Nightster and 2007 Low with the same front tire: brand, model, and size. D401F 100/90-19 57H. Perhaps they have their stats wrong, but my experience says, if you don't absolutely need the twitchiest steering available for on-track performance, go with the fat tire.

(Unless it's for fashion, in which case, don't even bother asking on the internet. Just go with whatever floats your boat. And that's fine too; we all do that about something!)

 

Mmm, "go with the fat tire." Now I'm thirsty for beer.

 

Actually what he says is correct from a scientific stand point. The fatter front tire has a greater mass therefore under rotation has a greater centrifical force. The higher the centrifical force the less an object is willing to change direction. Hints the reason that at speed the 48 wont feel as light steering as the Nightster/Iron but will naturally be more stable since the heavier tire is more resistant to change in direct from bumbs, rocks, cracks, etc.

Yes...Im kind of a dork.

 

That just ROCKS!! LOVE the wheels...
