Is it dangerous?

[C.G.]

To fall asleep whilst riding pillion on a motorcycle?

I keep doing it. Only on motorways though, not the bendy twisty bits.

Only to riders behind.

When they hit you there is a strong chance of busting their front wheel.

Was that really a serious question?

Actually, I also do it regularly, as do most of the pillion passengers I know. I don't consider it ideal, but I don't think it is phenomenally dangerous either. It would be exceedingly difficult to fall off. To anyone who doesn't believe this, consider that the rider's centre of gravity acts downwards through the bike. Getting off - whilst awake - requires some considerable effort against gravity, an amount of effort that most people would not be inclined to make in their sleep. Pillion passengers do not actively do anything to keep themselves on the bike - physics takes care of that for them. New or nervous riders sometimes think that they need to hold on, but this is a little like learner swimmers using an inflatable ring, when their natural buoyancy is just as effective as everyone else's.

FALL ASLEEP!!!!! Someone please try riding pillion with my cousin on his Yamaha R1 SLEEP I say SLEEP!!! White knuckle ride and certainly no time to SLEEP!! However there is no mention of the bike you are pillion on, for instance if it was a big Honda Goldwing or cruiser Harley then the pillion seat is like a nice big armchair and I too could fall asleep no prob but most super sports bikes I've been pillion on it's either hold on or fall off!!!
