I assume you are thinking of mounting the rear light above the exhausts,and fix it or replace the bit of black plastic trim?
Not a lot of space there.The trim covers the rear portion of the subframe.I guess the led CBR light might just go in.(Did'nt iang fit one of these to a 999?)Also be carefull of routing the wires away from the hot can.
As no-one makes a plate relocator for the MS yet,you will probably have to toddle down to a local engineering shop to get one made.
