difference between one and two piece rotors...
pops is ordering a 21 inch RC Comp front rim with matching rotor for his street glide.
poring over the RCC site, we couldn't decide on a one or two piece rotor for his dual disk front brakes.
what are the differences between the two, is one better, is one more recommended?

The advantage of a 2 piece versus over a 1 piece rotor is heat dissipation.
2 piece rotors also are not as prone to warpage from heavy high heat usage. 2 piece rotors also look better and racier than 1 piece rotors. Thats the only difference. I have never heard of a 2 piece rotor that could be taken off without removing the wheel from the bike (As Snarley stated)? I own high end 2 piece rotors on my Deluxe and where they come apart (The brake pad contact area) it is still inside the hub area.

Yeah, what Rockyriver said.
Best would be the 2 piece floating rotor which allows for expansion of the outer part of the rotor without warping.
Never heard of a rotor you could change without wheel removal, either.

With the Brembo front brakes I think a 1 piece will suffice just fine, but a 2 piece will dissipate heat easier. It's a Harley, not a sport bike.

Two piece rotors are basically floating rotors. 2 pieces that are held together by hollow rivets. They dissipate heat better and don't warp as much or as easily. They make braking smoother. They go on and come off just like solid rotors, they cannot be separated.
