wr250x gearing after installing shinko 244's?

Looking for advice on what sprocket set to try and regear my bike for the larger shinko 244 tires.


With the current tires, I feel the stock gearing is allready a little high. Does anyone know the diameter of the these (5.1x17) or should I just measure with a tape?

I am looking for gearing a little lower than stock after I get the shinko's mounted. A top speed of 75-80 and cruising of 60-65 would suite me well.

Running 705s I found 13/46 to be pretty good up to 60-65mph. Over that the engine vibrations start to fatigue my hands and feet pretty quick.

I think the OD of the 705s is pretty comparable to the 244s.
