The Zero S (now a streetfighter rather than a motard-style machine) and DS dual-purpose bikes both carry a 4.4 kW-h lithium-ion battery pack, good for about a 45-mile range in suburban riding. Both machines share a common platform and get numerous detail improvements, including the option of using a second, smart charger (that must be plugged into a separate 110-volt circuit) to cut the charge time in half, from 4 to 2 hours. Both Zeros have switched to 17-inch wheels (now with strong, MX-specification rims), and both have moved from chains to maintenance-free Gates toothed belts that—because of the smooth power of the electric drive—can be narrower, lighter and more efficient than the chains they replace. Perhaps more importantly, the belt will remove the annoying chain whir that was the loudest sound when riding these quiet electric machines. (A chain kit will be available for the DS if an owner is planning on a lot of deep mud or other severe off-road riding that’s hard on belts.) Brakes are from American-based HB Performance (better known as Hayes Brake), with a larger, 310mm front disc, and are claimed to offer a substantial improvement in feel and power over the units they replace. The repositioning of the Zero S as a streetfighter has seen its suspension travel shorten to a range typical of streetbikes, and it has also allowed its claimed seat height to drop to a low, 30.8 inches. That’s five inches lower than the seat on the DS, which now has a new, trail-tuned suspension with 9.4 inches of front travel and almost 8 inches at the rear. Detail changes to the frame and swingarm increase strength and reduce parts count.
