For what it is worth.. I have the pads... I have had the bike up in the air on both stands, rocked it back and forth, started the engine, put it in gear, never even came close to having a problem.
Now if you dont get the pads in the right place you might have a problem.
My wife got them for my birthday for me, and she ordered them over the phone, the salesperson asked her what she wanted, she said she didnt know and he recommended the pads. He told her if I prefered the bobins I could swap them out.
