does the fox eye fzs suffer with the sprocket issue ?

[butthead]

hi guys as the title asks , we know the mk1 has the drive sprocket issue or rather the drive shaft IS the issue, was this rectified by mk 2 foxeye or did this continue into this bike too ?
another question are  the boxeye and foxeye  seat the same ? fundamentally i think one was thicker ? but would the boxeye seat fit on the foxeye frame ?  thank you.
