1/31    Bike riders, how long can you stay on those race bikes (e.g. F4i,
        R6, Interceptor, etc) before your back starts to ache?
        \_ Motorcycles or bicycles?
        \_ Really depends on the bike.  A VFR (which used to be an Interceptor
           way back in the day) is quite comfortable, while an R6 will make
           you uncomfortable much sooner.
        \_ My back never bothered me, but my legs would cramp up after about
           two hours.
