Just depends on how badly you want this feature on your bike. I have ABS, but my wife doesn't. I don't have it on the CBR. My Ford Excursion and Ranger both have ABS.
The cars just came with the feature.... the bike was optional. Wife's bike was used, didn't have ABS... she's never had this on a bike, so it did not matter to her. I bought a new bike, she insisted I get ABS because of "the way that you ride...":shock:
I doubt she physically has the strength to engage the ABS on the bike, she might, but she's never tried my bike in a panic stop. She can't engage the ABS on the Excursion (her truck) even when she's tried practicing it on wet streets. She can't push the pedal hard enough... I realize she may if and when the time actually comes, but she has been unable to practice it.
It's all a matter how important the safety feature is to you. If you don't get it, it's just a matter of properly training yourself to brake the bike without ABS. I have to make that effort when going from the GW to the CBR... pull max on the GW front brake as hard as you can no matter what and the ABS works for you. Do that on the CBR and you'll find out what an ejection seat feels like. YOU have to manage the braking on the CBR...
ABS is an advantage, but some do not like it. I would weigh how badly you want it. If it is one of the top three features you want on the bike, expect to pay extra to get it...
