Yes . . . modern chains are pretty amazing.

What can I say? You say all this stuff will cause my chains and sprockets to wear; I say it hasn't worked that way yet. Maybe if I stuck strictly to paved surfaces--how boring is that?--you'd be right, but I've never gone 12,000-20,000 miles strictly on pavement.

This is hilarious. Have any photos ? What type of engine ? Do you have a particularly judicious right-hand ? Perhaps you only start on downhills ?
I missed the part where someone said you'd get shorter chain life if WD-40 were waved nearby the chain. Spraying it on and wiping it off . . . not much time for the kerosene to seep past nor into the o-rings. Try it yourself - take some buna o-rings and place them in kerosene.

I'd love to see those sprockets. 25K miles - sure. 40K miles. That would be impressive, indeed.
I get 20K miles from my KTM 950's chain and sprockets whether it's all pavement or the abrasive granitic dust in the CA Sierra. That's with a light right hand . . .
Chains are "great" primarily because they permit relatively easy ratio changes. They suck because it's clearly a "weakest link", are heavy, and expensive in the long run.
Ever seen an incident where a chain failed ? Normally, it's due to over-use. A shark-finned sprocket tooth leverages against an old roller.
Broken cases, locked rear wheels. Lots of damage to bike and rider.
Congratulations on your good luck. May that carry on.
