I know it’s all been said before but this whole issue makes no since at all to me. The gear indicator going - - especially. Gear position isn’t calculated. It’s a physical switch. As long as the bike is powered up it knows the gear position no matter what. Even on ABS models the only thing really needed is wheel speed and there’s two sensors for that. And ABS also works no matter what gear your in, even neutral, at any speed over about 5 mph or so. What any of this has to do with final drive gear ratios is beyond me.

It's ll down to garbage ECU programming. For whatever reason, Kawasaki has the ECU programmed to read rear wheel speed, and when gearing is changed, the ECU gets confused, (Ever ask a blonde girl what time it is?) and starts do'in stupid stuff. Since changing the gear ratios is very common, Kawasaki should fix their ECU. You can change gearing on any other manufacturer's bike, and not have this problem.

This is one reason why, as a software developper, I think that we overuse software. I know that there are advantages to using software but there is a price that comes with a more complex system.
