I do not find lane bumpers, cracks, holes, or any other irregularities to cause me that 'whoa schnickys' what was that feeling. But a perfect 90 degree to 90 degree S curve near my house is loaded with tar snakes and they always twinge to exit hole. Not bad but they keep me from doing aggressive practice turns. I find the front end very stable, but I am not a hard rider or a veteran semi-pro racer by any means.
