How can I tell if my seats been shaved?

[mickvp]

As title really. Arse is killing me after 90-100 miles. I've been on a fazer before and not had this issue, also, on the other bike I seem to remember only getting one foot on the ground, but on mine I can plant both feet (about 5ft 7-8) flat on the floor.

Any way to tell by measuring it, as I'm not sure if the seats been done or someones changed the dog bones etc.
