On an 04 mono the rear spring is 64 nm as stock, even I run a firmer spring - 70nmm and i'm 65 kg and can bottom the rear in a big dip. 05's get heavier springs (70nm for a mono) but may run a different leverage ratio. Like Karl I ride north Yorks, lakes bumpy stuff and need the suspension to work so its a fine balance between having it soft and not bottoming. thats been the same for every bike I've owned although none have grounded before but that might be down to them always being oversprung.
if you are heavier, ride bumpy roads and land in compresion dips and haven't put the correct spring/preload on or lifted your ride height theres a chance it'll do it, Comes down to correct geometry and suspension settings really. I doubt it'll do it cornering as fairing would grind first.
