I just finished watching BBC 2's Speed Dreams: The Fastest Place On Earth, a documentary about a group of British motorcyclists who travel to Bonneville to see how fast their folk-engineered motorcycles can go. It's a great watch and one of the best motorcycle focused things I've seen about Bonneville, and there have been many.
One of my favourite bits about this one is that it isn't one of those (insert celebrity name here) explorations of extreme motorbiking. Those can get thin pretty quickly when they lean mainly on the twist of watching a footballer or actor doing something that hundreds of others have done with less while the poor celebrity laments their fame and finds ways to make the trip as expensive as they possibly can. It might be time to shelve that formula. Motorcycling is inherently egalitarian. Millionaire problems while doing it just aren't that interesting. Meanwhile, Speed Dreams covers the gamut from build-it-in-your-shed eccentrics to bank funded high end amateur riders, but I find the ones who do it with less far more interesting. Money makes people tedious and shallow. It's not their fault, they can't help it, it's just what money does They end up with an audience because people like to watch wealth. The characters underneath it are nearly always atrophied by it.
Speaking of interesting, my favourite bit of Speed Dreams is when the Scottish lead engineer of the high end team comes out and waxes poetic about the shear size of the place...
You can catch this one on Motortrend TV with a free trail, or on BBC if you're somewhere they'll let you stream it. Amazon also looks like they add it in occasionally. Back in the day Top Gear (with the old guys) liked it too.
Other Bonneville Motorcycle Media:
Henry Cole's Worlds' Greatest Motorcycle Rides is a good series to get you through long Canadian winters and his run at Bonneville is a genuine tear jerker. That he's trying to do it on a Brough Superior is English eccentricity at its best. First time he met Sam Lovegrove too, so there is a good bit of engineering/technical to it as well.
