Convention for direction of rotation of rotary throttle contol (motorbike etc)

NY · 2021-04-06T08:31:04+00:00

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.One of the implications of this is that if the speed control is turned slightly too far in relation to how fast you are walking, the barrow shoots ahead, turning the control further *on* - until the barrow leaves your hand when obviously the throttle closes due to its spring. It's also uncomfortable to bend your hand back at the wrist to hold the power on; it would be more comfortable to bend the hand forwards (palm towards wrist).

Yeah.

I don't believe they are (other than the old stuff, as you say).

Whilst that makes sense, have just Whatsapped my mate in Canada (LHD country) and he confirmed front brake on the right (he was a keen cyclist here and still is over there).

Yup, horrible action. Digital foot for an analogue role. ;-)

Similar advice after leaving the 'Extended Rally driving' and 'Supercars' courses at Brands. ;-)

I just had a reply from a mate in the States (also LHD country) and he suggests that cycle front brakes were on the left over there?
