Zero Motorcycles has raised an additional $5.5 million in its Series A funding, bringing it’s total war chest to just over $10.5 million in funding to date. The Invus Groups seems to have lead, if not solely financed, the Series A round, and retains two seats on Zero’s Board of Directors. The funding is reported to “help grow the company”, which in these financial climates could mean anything from paying looming costs to amounting cash for harder days ahead. Whatever the reason, it’s a positive sign for Zero Motorcycles, and an early high-point to their 2010 accomplishments.
