引用motorcycle daily：
This still doesn't explain why Yamaha claimed that the bike revved so much
higher than it actually does. Whether or not the tachometer reads accurately,
the ECU certainly knows exactly how many RPM the engine is turning - it has
to, since it sends the signals that tell the spark plugs to spark and the
fuel injectors to open and close. Most ECUs determine engine RPM based on
signals from a sensor that monitors the rotation of either the crank or the
camshaft, and these sensors are typically extremely accurate. If they
weren't, the ECU wouldn't know where each cylinder was in its cycle, and thus
wouldn't know when to open the injectors or send a spark to the plug.
不是在幫yamaha找藉口。另一個不太可能的可能，就是ECU算錯了…
我是覺得一家這麼大的公司不太可能笨到騙消費者…
