Offset is the same, but diameter is different. The RR6/7 adds spacers between the calliper & fork leg, without these the 06/07 discs won't fit the 04/05.
If you get stuck for spacers give me a shout @Gravel trap will literally take a few minutes to make some.
thanks @mk3golfcab . I'll see if I can order any through work I'm off in next week to stock take but I've a feeling Honda will want a fortune so i am prob going to tap you up for some sir. I'll wear something pretty if that helps
Am back in work from Monday so can certainly sort you right out (as long as it is something pretty you’re wearing)
