I have a 2007 streetglide with the stock 16" front wheel. Coming from a fatboy, this bike is sooo nice to ride on the highway. Have seen the 2010 flhx with the 18" front wheel, and loved the look. A little leaner, but still factory. Some problems I am wondering about: 1. Diameter difference of 18" wheel/tire compared to 16" wheel if any, raise/lower front end? 2.Will the later style rotors work with my non abs/non brembo brakes? 3. Bearings/axles different? 4. Any major handling changes? Thanks.
