191 mph on a motorcycle is my top to date. I want to crack 200 mph on a bike and also a car in the near future. Not on an open road though. Head to Nevada for the Silver State Classic. See how fast you can cover to 100 mile section of closed road. I rode shotgun and navigated for a buddy. We averaged right at 160 mph (in a pick up truck lol). I would much rather have been behind the wheel.
