Six months after signing a letter of intent, Honda, Yamaha, KTM and Piaggio Group have signed an agreement for the creation of a swappable battery consortium. The basic premise, of course, is to allow customers of light electric vehicles, including motorcycles, to swap an expended battery for a fully charged battery at conveniently located stations, rather than wait for their battery to recharge.
