"And just like anything racers will get creative and work the bugs out of these bikes and get them to the point where their working awesome and will eventually be just as fast as the current bikes.
"Wrong. Wrong. And wrong.
Look at the evolution of motorcycles, I bet the original motorcycle creators never imagined motorcycles would be what they are today. By endlessly looking for any advantage over the competition the combination of R&D by the manufacturers, Pro racing teams, and individual racers all developing and incorporating new technologies has led to motorcycles being at the level they are today.
Motorcycle acceleration is all about power to weight ratio, the lighter the vehicle the less power is needed to do the same amount of work. Batteries are rapidly being developed that are smaller, lighter, last longer, and produce more power - electric motors as well. The majority of the weight of a motorcycle is from the engine (plus oil weight), cooling system (plus coolant weight), exhaust, and fuel (including the fuel tank and pump weight). Batteries and electric motors have more options in their physical design than a gas engine, this would allow greater flexibility in frame design (including frame width and swingarm pivot point location) and would make it easier to create that optimal mass centralization situation.
Another advantage batteries have is that you can incorporate braking systems which actually charge the batteries by using the energy produced by braking (already in use in some hybrids). Once a system like that is incorporated that means you would need even less batteries (less weight) if the batteries were being charged every time you were using the brakes. Performance electric motors can also accelerate really hard and are very linear in their power delivery.
So why would electric motorcycles not be able to be developed to the performance level of gas engine motorcycles?
