Earlier quoted context omitted.
By law a lot of motorcycle controls are standardized both to ensure sane controls (think suicide clutch) as well as standardization (1 down 4 up). Riding a motorcycle involves all four of your limbs having a dedicated control (left arm clutch; right arm throttle and front break; left leg shifter; right leg rear break). It is so satisfying having your body operate all of these controls without a conscious thought.
Do you happen to know if electric motorcycles are meaningfully diverging on these? Like how many EVs adopted single-pedal driving, are there e-motorcycle analogues?
Smaller ones (think 125cc equivalent or less) seem to have adopted the scooter layout, ie no pedal, only hand levers, possibly reversed (left front, right rear). I see a lot of those around Paris: https://vmotosoco.fr/gammes/tcwanderer
"Normal" ones, like Zero, seem to have stuck with the classic layout: front brake on the right-hand lever, rear brake on the right foot. https://www.zeromotorcycles.com/en-gb/model/zero-sr
I would absolutely hate to have those changes. As GP says, it's paramount to not have to think about the controls on a motorcycle. I usually ride a "normal" motorbike, but I was given a scooter once when I took mine in for service. The weird brake lever layout (left front, riht rear) was surprising. "Fortunately", the brakes had next to no bite, so nothing bad happened when I squeezed the clutch, figuring I should change gears...
Anecdotally, for a somewhat "half-way model", Honda has ICE DCT models, which are normal motorcycles, but with robotized and automatic gearbox and clutches. They're using the classic layout, but, like with the Zero, there's no lever on the left hand (sometimes there's a parking brake, but the lever is way out), and no pedal for the left foot.
