Connecting rod numbers

[Blower1]

Over the years, Suzuki has manufactured connecting rods with different number codes (492, 493, 494,etc.)

Many of them have the same main dimensions. Is there a number table of what was used in which engine?

I believe the 493 rods are known as 'Katana' rods and maybe originally from the homologated 1000cc engine. They are the 'go to' rods in drag race engines.

The 493 rods are thicker than other GSX 1100 rods with 18mm wristpin. Also Suzuki GN 250cc single cylinder connecting rod have

exactly same dimensions as GSX 1100 rods, nuber is 382. It is also the same thickness as the Katana rods.

I've got a 493 rod lying around I think, which dimensions you want to know.

When you buy them, the Suzuki dealer is probably the cheapest way to go, be aware that you get the same color codes, different colors is different weights

I have several different rods and I have measured them, so I know the dimensions. Thing what I like to know is why there are different numbers on connecting rods with same dimensions. Are the numbers by the engine, production year, material, strength, or because of some other reasons.
