Apparently Yamaha makes a freaking crossplane I-4 engine! It sounds amazing. So... when do we get a car with one of these?

Any reason for doing this, besides "because you can" and the unusual sound?
There are reasons for picking a flat plane l-4. One of them being that you with a 4-stoke 4 cylinder, you get one power stroke with each revolution of the crank, evenly distributed. With a cross-plane crank you shift 2 power strokes 90 degrees. The engine becomes less balanced, exhaust pulses no longer mesh in equal length exhaust headers, and so on.
So, Because Sound?

I have read somewhere that they are going for a Big Bang effect so that you can unleash power and then the tire has some time to recuperate between each interval. It is mostly done on bike engines but I think the Chevy small block has a similar sort of effect with its firing order.

Better torque characteristics, better throttle dynamics, less tire wear.
They are unreal to ride honestly, nothing like a normal liter bike.

The crank in a flatplane I-4 is inherently unbalanced due to it's weight being 180° opposed. That's why they're usually so rough. The crossplane is much smoother, and also has better power delivery. The trade off is that it requires larger crank counterweights, so they're not as responsive as a flatplane and can't rev as high. The wonky firing order also mandates a complicated and expensive exhaust system.

apparently the author has been living under a rock too. the R1 has been cross plane for i think 5 years now? (googled: first release in 2009. so 4 years now)
