My 2012 stock ECU has 6% added to my true speed. When I flashed it, I took that 6% out. It reads the true (or as accurate as it is able to) speed I'm doing now. I've had the bike up to 270-280kph numerous times, it gets up there easily. Anyway, I decided I wanted to make it to 299, and knew the 'track' I was going to use which was long and smooth enough.
Can I say, the difference between 280 and 290 is huge. My old man is an engineer, the maths is that with each kilometre you add the resistance goes up as a square of the speed. It's basically a parabolic curve of increasing force as you increase in speed. As I kept accelerating past 299 indicated, honestly, I was legitimately both scared and amazed. The wind resistance increase is hard to understand, how can just 20-30kph make such a massive difference? By the end the bike, the front end was shuddering, starting to vibrate like mad, and I didn't want to be there anymore. Slowing down to 270 felt like coming out of a hurricane back to pleasantville. I cruised down the rest of the straight at 270 and it felt slow-ish, and easy going.
Good judgement comes from experience, and a lot of that comes from bad judgement.
