Broken wheel ,
I am now building another wheel with a KLX250 SF rear rim. Does any one know what the proper torque should be? I think the spoke torque wrench is 4 Lbs / Ft .

If you have never built a wheel before.... you just cant whip it done.
To do it correctly, IMO, you need a spoke tension meter and know what the max stress is to stay under the limit. I have built several bicycle wheels and it's not easy peasy. I would call around and find a moto shop that has someone that knows what they are doing. Your riding it at 140KPH, HELLO!

that looks like a cast rim to me. look how coarse the grain in the metal is.... might be OK for a skooter but I'm thinking way too thin for a spoked wheel that works hard. you want extruded alloy wheels for spokes. plenty of cast wheels around, but they have thicker cross sections, I beam, H beam, and doublers where the load forces are, and no holes

that wheel was on borrowed time the day it was made. it is simply the wrong material, made by the wrong process for the task at hand. people (the Chinese) will make anything you are willing to pay for with no thoughts of the consequences. nobody here in America would make that POS simply because they know it would end up in court

No doubt, replace it. You can buy rims on ebay, on line, and from dealerships. You could buy a used one too. Any KLX250 from 1994 up and any KLX300 from around the same time to date have the same wheel, maybe different size spokes on some years, that you'd have to check, but bolt in.
If that's on the weld I'd see if you can get a replacement from the maker or Kawasaki, that's defective. Worst they say is no. Seems to me It should bend before it cracks and that doesn't look bent.

some alloys do not weld... well, they kinda do, but they break in short order. most anything that can be heat treated is probably on the "not" category. get a new rim...
