Keep in mind that racers are typically riding on well maintained pavement, are riding alongside other skilled riders - and most importantly, don't have to contend with soccer moms in their minivans drinking lattes and texting on their cell phones....Motorcycles got by w/o ABS for decades, and racers still don't use it....
I'm a big proponent of ABS but I'm not a fan of Hondas combined system. There are times (u-turns for example) where you may need to leverage the rear brake and don't want the front brake applied.
