how do cc's determine motorcycle performance?

Answer 1

an engines cc's are a measure of the displacement of the engine. like the chevy 4.3 Litre engine is equal to 4,300 cc's. and toyota's new 4.0 in the tacoma is 4,000 cc's. But it doesnt neccesarily reprisent the "power" of the engine. as the 4.0 listed above has more power than the 4.3

Answer 2

Here we go! I have a '99 H-D FXDWG with the twin-cam 88. That means 88 cubic inches. I'm not sure exactly what the cc's are, but I think it's around 1,450. Well, I get blown away by 600 cc Japanese bikes. The cc rating is not a good way to judge a bike. Depending on what you are looking for, performance, speed, dependability, you should look for what you want the bike to do. My first bike was a '79 Yamaha XS 650. Less than half the bike I have now, but it was much lighter and more manuverable. Now I'm an old fart, and I'm happy with the wind in my face in fifth gear at 45 MPH pulling less than 2000 RPM. She has twice the motor size than most of the Japanese plastic bikes come with, but can probably pull a train. You should look at engine torque specs. That will tell you more about what the bike can do at legal speeds. I don't own a car, I use the big 'ol Harley to do all my shopping, etc. I can't tell when I have the bike loaded. It just goes. Engine displacement is not everything. But two cylinders the size of soup cans sound better to my old ears at 3,000 RPM. (About 75 MPH. She goes, but she ain't quick about it!)

Answer 3

The cc's are the size of the engine. A bigger engine can draw in more air and burn more fuel, making more power. More cc's tend to make more power, but it's not completely straightforward. There are a lot of other things that influence performance. The most obvious is weight - a heavy bike with a large engine may not be as fast as a lighter bike with a smaller engine. But here are some other general tendancies - note that these aren't hard and fast rules; there are some pretty big exceptions.

Water cooled motors often make more power than air cooled ones of the same size.

Overhead cam motors often make more power than similarly sized engines with pushrods.

Engines that can reach higher RPM often make more power than the same sized engine with a lower redline.

And engines with more cylinders often make more power than the same sized engine with fewer cylinders.

Answer 4

Cubic Centimeters is like Cubic Inches. Bigger does not allways mean faster. Of course a 5000cc will be faster than a 2cc, but that is because of the volume and amount of fuel it can burn.
The real effect is the Torque to Weight ratio.
Performance is also a conceptuall word, one bike that can corner well might not be the fastest in the 1/8 mile. cc's also have an effect on this. Torque to Weight.

Answer 5

cc's are the size measurement of the engine
More cc's the faster, bigger the engine

Answer 6

cc's is how big the engine is. More cc's equals more power.
