Is there a convention for which way the handlebar of a motorbike etc rotates
to control the throttle? I ask because I have an electric wheelbarrow with
rotary throttle and it rotates the opposite way to the way I'd have
anticipated, so I wondered what the standard was.

The throttle is on the right hand side. I would expect to rotate the top of
it away from me to increase speed, and towards me (bending my hand back
towards my arm) to reduce speed. But it rotates the opposite way. Looking
end-on to the handlebar, from the end towards the central handlebar axle, it
rotates clockwise.

Motorcycle throttles are 'top towards you' to increase speed.

.... or as you say, looking at the end of the RH handlebar, you turn it
anti-clockwise to increase speed.
