Safety: Planes vs Bikes

I fly a small airplane (a Cessna 150) that is well maintained. I fly
over forests in good weather and typically during the day. My biggest
fear is the engine quits over the forest and I have no place to make a
deadstick landing except the tops of large trees.

I drive a moderate motorcycle (a Honda Nighthawk 750) at moderate
speeds through my small town and through the surrounding forests. My
biggest fears are either that I will slide on a patch of dirt on the
road and crash or someone will hit me with their car through
inattention.

I've been asked several times which of these things is more dangerous.
Can anyone provide some statistics on this?

Sometimes I walk across a street. My biggest fear is either that I will trip
and crack my head on the asphalt, or that I will be mowed over by an
innatentive driver of a car or moderate motorcycle.

Other times I move my bowels. My biggest fear is that if I strain too hard, I
will suffer a heart attack and die, much like famed musician Elvis Presley.

Can you tell me which activity is more dangerous? My insurance forms don't
seem to care how frequently I cross streets (even though I do live in New
York), nor how frequently I take dumps. Yet somehow, I believe I will extend
my lifespan by refraining from one or both of these activities.
