He's got to dismiss.
What next? "OK judge maybe he wasn't doing 150, but maybe 117; let's try 117." The cops blew it. If their initial facts are screwed up, they can't be allowed to keep changing them.
That's right. The kid's probably got a lawyer who's going to address other matters, such as distance traveled and whether, or not the bike was hopping over the cars that were out there that Sat afternoon. That road will allow only a short stint at something over 100 for only a very short time before other vehicles block the way.
The bike only has 75 ft-lbs of torque/126HP and the gearing is tall, so the bike's going to take some time to wander up anywhere over 120. From this and the other story, both of them punched it for a short bit, then slowed to around the customary speed folks roll along at up there.
I think the cop made this up.
