Back to FEAM question...
'Scuse my ignorance, but is the ECO mode similar to, say, the rain mode that I had on my Duke 690 and what other ride by wire bikes have? Seems there are all kinds of changes taking place on those modes, besides simply leaning the fuel. Mapping and ECU changes, HP and torque curve change, timing etc...
The Duke had three modes, rain, which was soft and worked well in traffic and dropped peak hp down to 70% max.
Standard, which allowed for linear acceleration with peak HP.
And #3, which allowed for power to come on immediately and pull like crazy. Believe it was referred to the kick butt/ticker getter mode...It was fun, but ya had to be thinking all the time or the flashing lights showed up in the mirrors.
