Replaced my Speedo cable about 1000km ago.
I wanna say I lubed it with white lithium grease, but I'm not sure now. Broke yesterday.
Should I have used a hi temp bearing grease, or a gear oil? Or was it probably a random bad part?

Use speedometer cable lube available from auto parts stores. Avoid sharp bends.

I don't love overly specific products, as they have a tendency to pile up and make it hard to find my gasketmaker, but I don't wanna replace Speedo cables once a month either😂
Especially in winter it takes an extra ten minutes for the job because of the windshield and bar gloves.
I'll give it a shot Frank, hopefully I'll be speeding trouble free by Saturday afternoon.

Sometimes there is a reason for "overly specific products"  |

Two or three things to consider when replacing a speedo cable. length ... if too long, you'll have to do something with the excess, and it may kink. routing.. if you route the cable along the wrong path, it can bind, or get damaged as you turn the handlebars back and forth .. lubrication. You need a very light coating of lubricant, not a big slurp. Just enough to get it 'wet' with grease should be adequate. Heavy lube will add to the force needed to turn the cable inside the sheath. placement in the cluster housing... interference or bending as you plop the cluster back in place after connecting to the 'business' side of the speedo can cause premature failure.
You cannot buy a cable stretcher as far as I know, but OTOH, if you have too much excess, you have to route it with nice easy bends or arcs. You can try spinning the cable from the drive hub manually to see if it spins freely, and you don't hear noises. Re-arcing the curves may make any noise less, or more loud, so move it around as you see fit.
You also want the gear in the drive hub to be lightly lubed.
