True, however in the context of a radial engine, a rotary

Not really. All that rotating mass of a rotary engine could have some
very nasty gyroscopic effects - might even make the bike too stable! It
could matter whether the engine rotated in the same or opposite
direction to the wheels.

I rest my case. What could be more exciting that that?
Sorry, if the joke was not clear:-)
