I think you are being loosey-goosey with your numbers. Nobody online seems to be able to get a stock zx6r above 160 mph. Sorry, I’ll believe it when I see it… if making a high-performance 200-mile-range motorcycle was as simple as adding a bigger battery somebody would have done it by now. The demand is there. But I think the sacrifices to performance and added cost would make that kind of bike-if not physically impossible-at least impractical to build.
