It's a good way for him to die, only a matter of time. "Here's your sign." Problem is he'll be taking out another vehicle or two when it does happen.
His mom should come forward and turn him in otherwise she's supporting his behavior. I like that $1500 fine she has to pay and that they've seized the bike.
Sounds like there's key witnesses that police have had come forward. Bet that idiot has confessed to several people about his antics and his video and they'll attest to it. He doesn't need to confess to authorities about it, sounds like he's already done that to others that have come forward.
On another note, watched a TV show last night on MV Agusta's F4 liter bike, it can go 189mph stock (that equates to 304kph). Holy fricken cow! It's a beautiful piece of machinery. I'm sure this R1 has the standard speedo error that Japanese bikes have so in reality it was prolly quite a bit less than the 299kph indicated but still plenty fast. Motorcyclist tested a 2010 R1 and claimed a top speed of 165mph (266kph). So yeah, there's some speedo error.
