Quickly reading through the majority of the answers... Mind. Blown.

Honda NR oval piston. 8 valves per cylinder and two conrods per piston.

More specifically, a well kept but tired XS750/850 that I can then build into something like this. It's not unreasonable (clean one, well maintained one nearby for 1200$) but it's been a hard year for me and I'm not making any extra this year. http://www.bikeexif.com/custom-yamaha-xs750

Already did. Several times. Moto related. http://www.odd-bike.com/2012/11/six-years-with-ducati-916.html

And to think they axed the 912 and replaced it with the 914 - and potentially this bastard inbred offspring of a Lotus Elan and a Europa.

Some people like the dull, simple, predictable life. They can have it. I spent a few minutes listening to a middle aged suburbanite tell me about how he fell asleep on the commuter train and missed his stop. This story was the highlight of his goddamn week. This same person will spend 5 minutes explaining one fucking…

Very cool. But I am getting real damn tired of these art student videos about mechanical stuff that put all their focus into cool shots and trendy music... Then DON'T PROPERLY RECORD OR PLAY THE GODDAMN ENGINE NOISE.

The Boomers horrify me. As a twenty something who grew up on a farm, moved to small city, and then to a big city, the prospect of settling down into a quiet suburban life TERRIFIES me. Get mortgage, marry dowdy wife, have bratty kids, sell your toys - then the cycle of sleep, drive to work, work, drive home, fall…

BMW flying brick or an old airhead boxer. Change the oil regularly and check the valves once and a while and you can do some ridiculous mileage. I personally know someone who put over 300 000 miles on a K100RS. I've met a few guys with 100-200k on old boxers.

Apparently you've never seen a 'Busa powered Smart Car.

Yes poor me. I've been riding, fixing and occasionally building bikes since I was 17. I'm entitled to my opinion, as you are yours, and as they are theirs.

Damn, apparently tractors have come quite a ways since I was driving them. "Mine" was a 1955 and only had the clutch to stop it. Fun. Not that it could go fast enough to be dangerous.

Lincoln was once the Cadillac of cars,

I'll bet its gone viral, so they needed to capitalize on the web traffic. Again. Still.

The funny thing is that tractor in the pic is edging into supercar price territory. Probably close to 200000$ depending on options/powerplant.

Here's a stick. You can poke me in the eye with it, I'd rather that than either one of these crap barges.

Aww, you guys are adorable.

I love retro bikes as long as they are worthwhile machines that simply appear to be classically styled. I despise sub-par, overpriced, underpowered, flexi-flyer, nostalgic garbage passed off as "retro" (cough Triumph Bonneville cough Royal Enfield Bullet hack).

My dad had a 1973 R75/5. They ain't exciting bikes. Gearshift was terrible, you had to take your sweet time. Easy to handle though, very light feeling with a low centre of gravity and a comfy position. I remember constantly flicking the chokes on with my tips of my boots by mistake (it had Mikuni CVs with finger-tab…

Holy sweet mother of mercy I want to try. I learned to drive on a 1955 International that looked similar to that. Something you should note... There aren't any brakes on those tractors. You stop/slow down by disengaging the clutch (like a riding mower). How the hell would you stop this thing?
