"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."
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::Dallara said:~
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...

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