If you mean the gears on the shafts, while ideally a service manual would be preferred 

the parts fiche despite lacking details can show in what order everything fits on:

You'll have to figure which one above applies to your bike

as I've never understood Suzuki K1, K2 K3 etc, model differences.:excuseme:

If someone want's to explain it I'll have learned something new today. :prof:

I've often wondered myself. My thought was maybe matched cases but really have no clue

Maybe moto367 knows

2001 RM125 through 2003 125's are no different in how the transmission goes together or even the part numbers. There is a difference in the models 01/02/03 in other component configurations and electrical components too. In the Power Valve Assembly the 2003 RM125 it changed. In the 2001 RM125 the Wire Harness is longer. Also with the Power Valve assembly the 2001 and 2002 where the rod connects is not the same. But the Casing Set allows you to use either components to build it to run it. With those differences Suzuki decided to post Year Model for separate OEM Part Numbers. Check out the Power Valve Parts Illustrations to confirm my explanation.

Easiest way to install tranny is to simply hold it in your left hand, tip right side case vertical and srick it in that easy. Doesn't matter what year or brand except 99+ yz250 and yz85s you have to put forks and drum in with gears

It has been awhile since I last logged in to see what was posted on this thread. That technique for installing the transmission gears will be tried by me on my 3rd engine build. I am looking forward to trying it but my patience consists of a 3 strikes rule. Needless to say, I will try it 3 times and then take a break before trying again if I get it close within the 3 chances.

Have you posted a You-Tube Video showing that technique?
