To add my non-physics uneducated post, I'd have to guess that mass has
more to do with why the bike keeps going further than your body does.  You
may be onto something there with the cordura and kevlar hooking up a
little though, but I can tell ya' first hand that denim doesn't provide
any abrasion resistance and will be "gone" before it has a chance to slow
you down any.  Additionally the pegs and bars digging into the
pavement should help slow the bike alot making me think mass does have
alot to do with the why the bike keeps going.  

Physics majors?  Engineers?
