In a word yes, the pillion hangers are identical from 2012 onwards, gen1's also fit but have a box section appearance and are finished in gloss black so wouldn't look so good on a gen3. All pillion seats fit but the gen1/2 seats are humped and aren't that comfortable for use over distance, S1000R pillion seats also fit (I have a comfort version on my gen3) and as they are flat are more comfortable and look identical to the 'official' gen3 seats. For all the seats it just a case of swapping the lock barrel from your seat cover into the pillion seat, 5 minute job.
