Ya, but then you'd have to take off fairings to get to the oil filter and change the oil and adjust the valves. LOL . I don't like faired bikes except for race bikes and then you need to go with the whole design...fly screen, clip-ons to get you down under the air resistence. These bikes are more mainstream as they are presently designed. A faired option would be fine though.
I am always for better range, higher sustained speed, better acceleration though except not at the expense of weight or much weight gain. Even though I have a 2013 Zero S, I would buy a 2014 if it improved in those three areas with no more than 10 lbs weight gain total. A sustained speed of 86 mph rather than 80, acceleration 0-60 mph of under 5 rather than under 6 seconds, and a highway range of 65 miles at 70 mph rather than 53, all with no more than a curb weight of 365 lbs rather than 355 lbs. I have no idea if it could be done. A quicker charging system is not important to me. In fact I prefer to plug into 110. I like the upright seated position too and looks of the bike. Smaller changes like improved tires, brakes and suspension (not really so small I guess) would help a little, but lacking the big 3 improvements, I'll probably not buy another Zero S in 2014.
