Hey Trev, can we have some more info?
How did the Ikons compare price wise?
Where are you looking at getting either or from?
As far as the progressives go on Di's bike, my humble opinion would be that the 412 would be fine, light bike & light rider & all.
Ok someone might be useing them am thinking of fitting a set of 440 on my 03 ultra on the rear at the moment the brand i have on are not doing there job,or do i go to la-frog and fit fournales,the cost is a bit high but you get what you pay for and they are the way to go.Charlie
