ABS is just another tool that can be used if you want, the same as having brakes that can be operated using only two fingers. Where ABS is probably most useful is when you've cocked up and need a very quick e-stop. There's no guarantee it will save you but when all else fails it's worth a try. Anyone who finds themselves using ABS on a regular basis has several things to learn about riding but the same could be said of anyone who needs e-stops on a regular basis.
Do people not think this is important to master such a skill rather than having electrickery do it???
Oh yes. I also think people should master such skills as how to use a manual advance/retard, kickstart a bike, remove two bits of leather from their drive belt to change gear and pee on their carbide to see their way home.
Alternatively, they could just choose to ride whatever bike they like and learn how to use that properly, ABS 'n' all.
Everyone is entitled to my opinion.
