Nearly every component of the Zero S and Zero DS has seen major upgrades and improvements. With a bold and completely new look, the street and dual sport models will become the world’s first production electric motorcycles to feature a maintenance free belt drive system. The quiet operation of the drivetrain, when combined with each of the motorcycles’ overall improvements, yields a sophisticated silence during riding that speaks to their overall solid build quality. Zero has also increased the capacity of the power packs by 12.5% to improve the motorcycles’ range. Among the other upgrades are more robust wheels, a new HB Performance braking system, tires with better grip, more robust hardware, new aggressive profile foot pegs and an integrated ignition switch and lock. Unique to the Zero S, it has been lowered by two inches to improve street handling and the new overall package gives it an eye-catching naked look.
