I am scheduled for my 15k service in a week. I am doing a chain and sprocket. Both have endured a lot of WO throttle time and I am going better safe than sorry.

Part of this is I don’t expect to have the bike at 30k miles so just precautionary and making sure stuff will be OK when I choose to sell.

I replace mine around 15,000 miles as preventative maintenance, they usually look quite good, minimal but visible wear on the pins, but begin to require regular adjustments at this point. I keep mine very clean, never physically need to wipe the chains off. My bikes are stored indoors but ridden year round and near salt fog. I primarily use dry film teflon style lube (3m teflon chain lube, or their multi purpose).

Worst chain I've ever ridden on, came under a GSXR1000 and was missing about 10% of the rollers. Just pins visible. It was well beyond it's lifespan. Replaced it as soon as the bike was home.

The best way, measure the length. Chain manufacturers and motorcycle manufacturers have a maximum length allowable for X amount of links. Measure the stretch and replace when it gets to the limit, maybe early if you ride like a raped ape.

The red dust of death!

I usually push it well past that.

I do too. I change the chain when it starts singing to me.
bike X miles=smiles
smiles ÷ bike=miles
miles ÷ smiles=bike.
It's simple math.

I've replaced chains ranging from 20,000 ~ 35,000 of use, depending on how abused they have been. 25K is a comfortable interval for me personally.
Why do you feel this ratio has any significance with regard to sprocket wear? I usually find the rear sprocket to wear faster than the front. The few times I've owned a bike long enough that I had to replace sprockets and chain I could barely detect any wear on the front sprocket while the chain was noticeably stretched and showing obvious wear at the rear sprocket.

The rear having a bigger diameter will have a harder time fitting to a stretched chain. That misaligning of chain and sprocket teeth will accelerate wear at the point of pin and tooth contact.

The front having a smaller diameter and therefore fewer teeth in contact with chain pins at any one time means even a stretched chain can still fit okay relative to the rear.

it wouldn't surprise me if they generally use a higher strength steel for the front too
