When I was at the dealer yesterday, they had a Ninja 400 in Blue non-ABS model. I glanced at the rear brake/wheel and noticed a grooved ring similar to the ones on the ABS models. Do the non-ABS models actually have ABS on the rear? I'm not sure if having rear ABS would be that helpful anyway. Just curious since I did not ask anyone at the dealer to confirm and it slipped my mind before I left.
