Apparently they have 210cc 25hp engine available.. is there any reason someone (or they themselves) couldn't throw that into a bike to see how it performs in real-world? There are plenty of 250-300cc bikes around with comparable power ratings, so you'd think it'd be feasible project and a bike sounds much simpler than car/aircraft/etc
