For 2019, the DS and DSR range remains largely unchanged. They both share Zero's Z-Force air-cooled electric motor and are equipped with a 3-phase, high-efficiency controller—550 amp for the DS and 775 amp for the DSR—with regenerative deceleration. In addition, the new DSR now comes standard with a suite of Zero's best selling accessories, including a dual-sport windscreen, tank grips, hand guards, and a 12v accessory port.
