1994 to 2010 Sportster 11" Rear Fender for 250mm conversion

If you want a good looking not hacked up Phat tire job, then you need a great looking fender. Our 11" fender is made from heavy gauge steel for passenger support and cut to fit.Use with stock seat or any Sportster seat you wish. You can leave the rear of the fender long for that tail dragger look or crop it anyway you wish.
The only way to put a 250mm tire on your Sportster is to cut off the stock fender supports just behind the shock mounts, you can then fab up some of your own hidden fender supports or purchase the one we use in our world famous PHATSTER KIT.
