Natural gas motorcycle?

Hello together, since there are developments in the direction of e-motorcycle, does someone know if there are ideas in the direction of natural gas (or car gas etc.) driven motorcycle? I mean, after the automotive sector has been working on it for a long time, what would speak against it with the motorcycle? I personally would have spontaneously only two disadvantages which go hand in hand, however… First the (still) low gas station density, second the (still) low range in gas operation. But these disadvantages could one yes how to minimize the car by a bivalent operation…. Would the community even start on such a thing if it were available? Looking forward to your opinions, Mfg Alex
