140mph might be stretching things a bit. I've hit 105 (indicated) on mine, but that's completely stock so I was probably only doing 95. You're right, you can change the final drive ratio with pulleys and tires, but as you increase the theoretical top end, you reduce the power delivered to the road and you still hit the power vs. wind resistance brick wall; probably at a lower speed. If you need to demonstrate this to yourself, see how fast you can go in 4th gear. Then try again but shift into 5th around 60 mph. You won't be able to hit your 4th gear top speed because you run out of torque earlier. That said, I'd love to try a 1/4 and see what I can do, but I'm not going to push my bike that hard. I like it too much to abuse it that way. When you get a chance to try it, let us know how you do!
