Trek - I just finished the break-in on my 09 Ultra. Was given lots of advice, mostly "break it in like you plan to ride it" as others have said. I'm an engineer by trade, and my view is that its not the speed that's important, but the engine RPM. You can potentially ride the same speed in different gears and still be working your motor thru different RPM ranges and loads for a good break-in. Would also make sure you don't "bog" the engine below 2000 RPM. Its easy to do in 6th gear if you don't get up over 60 mph. Again, believe its all about the RPM and how much load you put on the motor. Cruising is less load than acceleration. You need a little of both. Enjoy, my Ultra is just an incredibly smooth ride!
