Driving a 1989 Acura Integra (brand new) between Wikieup AZ and Kingman, (a long flat downhill stretch of open Highway) I had it pegged at 130 for at least 40 seconds and I'm pretty sure the car just kept getting faster. I'd estimate somewhere's around 135-138...
On two wheels, 132 on the CBR 900.
Never had the X over 80 mph though, just good common sense :rolleyes:
