From May...

http://www.motorcyclenews.com/MCN/News/newsresults/General-news/2013/May/may0913-yamaha-planning-crossplane-dynasty/

"What about CP2 and CP4?
Yamaha hasn’t shown a ‘crossplane-inspired’ twin yet, but the CP2 trademark suggests a motor is in the works and Yamaha already has a couple of engines that could form its basis.

Following the crossplane logic, the CP2 would be an inline twin with a 270° crankshaft to mimic the smooth torque delivery of a 90° V-twin. And that’s something the firm has already created, using 270° twins on both the ageing TDM900 and the relatively new XTZ1200 Super Tenere.

The 270° crank on these twins does the same job as the R1’s crossplane crank, reducing the inertial torque to provide a smoother power delivery.

The CP4 trademark is presumably aimed at the existing R1’s four-cylinder crossplane engine and future motors. But Yamaha might be concentrating on the triples and twins, because while it has trademarked the ‘CP4’ acronym it hasn’t trademarked a logo to go with it, as it has for the CP3 and CP2."

Given Honda's return to 500cc twin engines you knew this had to happen. I'm glad though, this is the long over-due return to "The Basics" stuff that's needed to happen to get more people interested in motorcycling again. A more diverse product line and less specialization. The return of the UJM. I hope. It's tough being a dealer these days and only selling sportbikes or dirtbikes or cruisers or scooters for your share of the market and then being able to predict that market as it comes around before you order your product. Sometimes you hit it, sometimes you don't.

CycleWorld has some new pics uploaded. Kevin Cameron seems to think displacement will be near 900cc and will sport some sort of variable valve timing. The engine looks very compact front to rear. Hopefully, some competition for the Tiger 800 and BM's GS800.

It certainly seems to have more chunky exhaust and very TDM look to the motor..

It's the motor they desperately need for the rhino/whatever it is now and any new rZR like machine that they hopefully build.

That's my guess...

I sure hope this (or a Rhino) is not what that new engine is being exclusively designed and developed for...

Be a shame to waste that wonderfully compact 900cc parallel-twin on nothing more than a leaning three-wheeler, or even just a Rhino...

From it's appearance it has a stacked gearbox so it's doubtful that it's going in a Rhino. Unless they have a another version of it w/o a gearbox and if they do, lets hope it's a 1200cc version for the Rhino. And nothing more than a Rhino or Ranger would be about 85% of our sales (552 units in 2012) in our store so that wouldn't be a waste at all from my standpoint. ::008::

More info...

In one of the views of this engine, a card on the stand begins “90 x 71.” If these numbers are the bore and stroke, they make this Twin a hefty 903cc, which is consistent with the very large butterfly throttle bodies on the rear of the head..

and...

A look at the cylinder head raises a question: Why is there a larger housing above the exhaust cam’s sprocket (yes, the cams are chain-driven) than above the intake cam? Could that bulge conceal a powerband-broadening exhaust cam phaser?

and...

The location of the cam-chain tensioner on the rear of the right-side-mounted chain housing indicates forward engine rotation....

900cc, VVT?

not vvt... its the decompression device. Sorry to burst that bubble.

How do you know?

If you open enough engines, it becomes pretty clear. There simply isn't enough room next to the exhaust cam for a vvt indexer. If you look at heads like ours, four stroke singles, and others with decomp, they all look pretty similar (well, at least the modern ones do). If it makes you feel any better, decompression is kinda like vvt.

I was still hoping for the Tenere Mini-me. 8)
