I been having the same problem for the last two years with my 250 '08, the front caliper freezes up when is cold. I have rebuilt this brake once due to my dealer telling me that it was water freezing up inside the brake line. And to put new seals and to put new fluid and to bleed the lines. I did this and still has the same problem. The more that you apply pressure to the lever the more difficult it becomes to rotate the wheel. I usually have to blow hot air with a blow dryer to get it going. I have not been able to find an aftermarket replacement or an upgrade for this caliper. Help.
