It has.
Some of the MotoGP teams are working on "fly by wire" controls.

Nope. Not if you mean the twistgrip. We used to have throttle levers instead. Twistgrip didn't come along until late in the scene.

As to the actual throttle itself ,misnomer actually, not all flow control systems work by throttling the intake. Been lots of ways of doing that.

The schraeder valve in the tyres is probably the longest running development without being changed in the last 80ish years

Sparkplugs has been about for a goodish while. Not sure when hot tube ignition breathed its last , but the sparkplug has been sparking away since at least 1900, in pretty much its present form. Invented by Oliver Lodge, Robert Bosch was supplying them in 1902,Albert Champion started the Champion Sparkplug Company in 1904.

Does a 1900 era sparkplug fit into a modern bike (or car for that matter)?

Another interesting thing about spark plugs. I was reading an old motoring mag from the mid 1920s. A Champion spark plug ad listed the price at 5 shillings
They were still the same price in the mid 60s. I doubt any other essential item has stayed the same price for so long.

Indians had a left hand throttle,and Harley's for many years used a wire instead of bowden cable,and the throttle didn't return when you let it go,true push pull.

Over-priced to begin with or became easier to produce (more cost effectively)?
