Current version of the FJR that I ride is fuel injected, has electronic suspension adjustment, fly-by-wire throttle, cruise control, two performance modes, ABS, and traction control. All of that, and it's about the same price as it's been for years.
Is that 21st century enough for you?
The problem with all that stuff you're asking for is that it costs. Yeah, cars have it, but for the most part they wouldn't if it wasn't needed in order to meet emissions limits. Bikes can meet those limits more easily, primarily by being smaller engines. Thus you see the "cool" stuff on bikes upwards of 15,000 dollars, because the big-engine bikes need FI and such for emissions. Once you've got FI, the rest is actually pretty easy, just a matter of sensors and programming.
Thing is, nobody wants a 15- or 20-thousand dollar dirt bike, do they? Or a 500cc twin that costs that much. So those bikes get carbs and basic electrics. Or they die on the showroom floor. Why would anyone give a significant fraction of a house in order to buy a motorcycle?
