New R1 uses M1 firing intervals.
In the supersport liter class, there’s always lots of talk about power. You expect that. What you wouldn’t have expected – until now – is a radically superior way to deliver that power. Introducing the 2009 YZF-R1, the first ever production motorcycle with a crossplane crankshaft. Crossplane technology, first pioneered in MotoGP racing with the M1, puts each connecting rod 90° from the next, with an uneven firing interval of 270°- 180°- 90°- 180°. This all but eliminates undesirable inertial crankshaft torque, which allows the engine’s compression torque to build smoothly and provide a very linear power delivery out of the corners. It’s a feeling that’s simply unmatched, like having two engines in one: the low-rpm torquey feel of a twin with the raw, high-rpm power of an inline 4. In fact, the new YZF-R1 is not a continuation of existing supersport development; it is breakthrough technology that represents a paradigm shift in both technology and performance.

RoadRacing World has the full artical as well and a bike in yellow
The exhaust which I can't see from the rear kind of look like the 06 - 07 ZX-10...
Hmmm...

Say good bye to the old cammy hit I4 and hello to virtual V4... now if
Yamaha can do something about the I4s inherent heavy crank and gross
width of the engine because they you'll enjoy all the advantages of an V4...
anyway one test hop and you'll learn first hand what I'm been harping
about... 180º I4 is dead and buried because crank phasing drastically
affects power delivery...

So much for the fad of under-engine exhausts. The new crank is a great development, and differentiates Yamaha from the rest of the I-4 herd. I would guess it will sound quite a bit different as well.
This bike will bring Yamaha back as the leader in the literbike class, as the '98 R1 did a 11 years ago and FZR1000 two decade ago.

Sounds more like a twin, like an heavily muffled Ducati which revs impossibly high. At least to my ears.
