What are the differences between the 4th generation and 5th
tion engines?
I was comparing the two and besides:

-the 222hp @ 6400 RPM in the 5th generation and 190 @ 5600 RPM in the 4th generation.

-The 5th gen also has higher torque, 217 as compared to 205.

-The 4th generation has a higher displacement. (what the hell does displacement mean?)

What exactly do these specs mean. Can the 5th generation stand higher rpm's and therefore reach 222. How is the 5th gen's engine physically different. Would a stock 5th blow away a stock 4th?

There are people here much more qualified than myself to answer some of those, but…

Displacement is a measurement of the amount of fuel/air mixture the cylinders can hold. Think about it this way: If you took a 3.0 Liter engine (that’s liters of displacement), it would take 3 liters of water to fill all the cylinders to the top. Obviously the more displacement, the more potential for power and the bigger the engine.

Displacement is also measured in Cubic inches (as in a "Chevy 350") or cubic centimeters (usually on motorcycles- "Ninja 600cc")

As far as the 5th gen engines, from what I’ve heard the horsepower/torque gains were made through improvements in the intake/exhaust.

The 5th Gen has a new intake manifold and variable intake runners. Also, the 5th gen has a variable flow exhaust. Mainly, it''s just a tweaked version of the 4th gen engine. As Adboy mentioned, displacement is how large the cylinders are in the engine. The 4th gen and 5th gen essentially share he same engine, the VQ. They are both 3.0 L engines.

Don't forget the versatility of the metric system.

a bike with a 600CC motor is .6 litres. A max has 3000ccs of displacement.

1 cubic centimeter is one militer, and 1 cc or mililitre of water weighs 1 gram. Thats where all these measurements come from. 1 litre of water weighs 1 kilogram.
