That guy is supercool. I didn't like the look of his other norton with the humped tank and angled seat, but he is obviously a very talented guy. I love that he takes this bike out once a year, rides it 100 miles, then puts it away, to sleep until next year's ride. That guy loves that bike... it's a very cool bike.
I have the same fairing mounted on my commando. I don't think it makes my top end faster. It's pretty large as fairings go. I have gone 100mph on mine where if you duck down behind it at speed the suction pulls the sunglasses right off your face... I've lost 2 pair of cheap sunglasses so far in the same spot on the hiway where I like to crack open the throttle.
