Piston diameter?

Parthe said:

So the bore is the diameter of a cylinder and the stroke is the height? I know "Height" does not equal "Stroke" but for the sake of this equation it amounts to the same, right?

Thanks for the reply R-III-R, this just goes to show that everyday is a schoolday.

While I was willing to be fast-and-loose with the capacities (a "2300 is close enough" approach), using the correct names is fairly crucial, especially if I've mixed up the diameter and the height (bore and stroke?).

> Bores & strokes (diameters or radii, & heights)

Sucks to be you
Are you still wrenching on Rockets or what do you spend the time on these days

No you're right, height of a cylinder is effectively the same as the stroke (swept volume of a cylinder) for volume or displacement calculations.
FYI combustion chamber volume does not count as engine size/displacement.

Google has a handy calculator. Here I used the bore & stroke dimensions from Triumph for the 2.3L bike to calculate overall engine displacement (2294cc)
(note the bore & stroke are in mm so you have to convert that volume to cubic centimetres by dividing by 1000)

But, 795cc x 3 = 2295cc?
Heheheh just yanking . .
Good info!
