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.

I used to have a push bike with a twist grip for the (3 speed) gear
change. It was remarked that it appeared to be the opposite way to a
motorbike; to go up a gear you rotated the top away from you.


But it still pulls the cable in the same direction. Its just that a
Sturmey Archer gear and most road bike derailleurs change to a lower gear
as the cable tightens. MTB changers tend to work in the opposite fashion
though.
