I've got an R6 seat on mine, I didn't do the work but the subframe has been altered to suit it. Whoever did it has done a cracking job, the pillion seat release cable and lock are all there and the angles all look right. The seat has been altered slightly at the front and all fits nice so I'm guessing the R1 unit would work too.
Rust never sleeps !
