looks alot like a rotax 122 crank

@1337ASM They don't rev as high.

The problem is there is only 1 stationary gear. Rotary engines could rev higher with 2, but that would complicate the construction.

750cc 5 cylinder 150hp (67mm bore X 42.5mm stroke X 5 cylinders :)

1500cc 3 cylinder 300hp (110mm bore X 52.5mm stroke X 3 cylinder) Perfect insanity.

@SparkDischarge why not go rotary ? =]

[SparkDischarge]

@CadetLD Because they do not rev as high as motorcycles do.

Because they can add more cylinders.

[SparkDischarge]

@Ranger0n20s No. There is a reason MB used 5 cylinder diesels.

There is never more than 1 piston/connecting rod assembly stopped at any one time.

[SparkDischarge]

Why didn't they just use a 5 cylinder?

[CadetLD]

For as big and mean the CPC makes a small, 1.0L, inline-four sound, why not use that technology on say a 2.0L for a sports car or somehting? I know theyve designed automotive engines in the past. It would definatly turn some heads when they hear the exhaust.

I have an 08 R1; I prefer the sound of that to the CPC version.

[SovietSlayer]

i want a yamahar too

6:12 "You actually got an inline four that thinks it's a v-four"

Having a v-four myself I can say; That's pretty awesome!
