Admittedly, there was a reason. I'm now fully licensed to ride my scooter, an MBK Nitro 100cc thing which goes from 0 to 30 faster than you can fart. Got it up to 50 on the ride home, with plenty of acceleration to spare. Top speed (so I'm told, didn't have a chance to test it) is 68 miles per hour. But even so, forty feels damn fast.
