I know this question ranks right up there with what oil to use but i have searched the forum for a few days and haven't found a what i am looking for. I have the common problem of the front brake going soft after a day or two of not not riding. i did the rebuild and the results are the same. There are a few more tricks i picked up while searching i'm going to try but i think its time for a new Mc. so i have read that an 07 or an 09 mc will work on the 06 but haven't been able to find out if i need the calipers and rotors too or i only need the Mc. i have also read there are a few options like an r6 or an r1 but unsure of the years. So after that long winded intro what i would like to know is what will fit and what do i need. it seems like all mc are fairly pricey so i would like a few options so i can research it and find one that suits me. i don't do any track days and i really don't ride it to hard. Thanks.
