they look pretty good to me man.Chains stretch sprockets dont.

On the way out. Always replace the whole set as they wear together. Never replace the chain only.

Still got a bit of life still, maybe another 15 hours.

I'm just doing mine @ 60-70 hours. All depends what sort of riding though. MX maybe every 10-15 also depends on the kit.

Yeah was planning to do sprockets and chain together but didnt want to spend up before i needed to....cheers i won't bother just yet......just seems like every time i ride i have to adjust the damn chain(lots of K-waka power surging through them i guess)hahaha

I did the front only a few weeks back, though my chain was not stretching.

agreed, looks good to me.

geez you cant've been riding it very hard!! keep an eye on that rear one though, alloy ones wear quite quick once they get going.

i usually do two chains to one set of sprockets, by then they are quite sharky. lol

I always replace as a set, then I know everything is sweet. If your sprockets are stuffed they will stuff your chain and vice - versa. Rather pay the extra $40 - 50 for the sprokets and not ruin a chain

intersting, i do 2 sets of sprockets to a chain. but i use x-ring chains. they seem to last a bizillion times longer than standard ones

I do 2x DID Xring chains per set of Talon sprokets Its the chain that ruins the sprokets. $170 chian on a 450 last less then 30 hours till it is so stretched it bends the wrong way.

Always need to keep in mind the tiny front sprocket wears at a much faster rate and more chain wear is generated by the very tight turn around front. Plus huge load being concentrated on a small section of chain. To keep wear rate of set in balance I reckon front really needs to be kept in better condition than rest.

Front/rear teeth ratio usually about 3.5:1 so I got 3 front sprockets for my new set but I doubt that covers it. I'm guessing wear rate is unlikely to be directly proportional to ratio.

Worn front sprocket - you are the weakest link. Goodbye.

also fortunately the cheapest link too!
