A larger 19-inch front wheel, Pirelli MT-60s, fully adjustable suspension, and 7 inches of suspension travel are traits that remind us of adventure, but a li-ion battery and an air-cooled interior permanent magnet motor? No gas power? Yup. The Zero DS and DSR are designed for adventure with the 21st century twist of electric power. Want even more? The DSR Black Forest Edition is even more adventure-ready with hard bags, touring screen, and hand guards. The Black Forest Edition is new for the US.
