Rust on chain?

The chain on my bike has recently (over the last 5,000KM) started to show rust (or something red) on the surface of the chain and in the drive sprocket cover.
I clean the chain every 1000KM (without failure) and lube with plenty of chain wax. When touching the chain it still feels very waxy, but this red deposit wipes off the surface. Is the chain rusting or is the rust getting on the chain from somewhere else?

This is the original chain and has done 29,000KM.

Your upper picture of the drive sprocket appears to show "hooking" (see your owners manual for that under sprocket wear in the maintenance section). I think that you are getting due for a new chain and sprockets.

Agree with jsonder. Visible surface rust is nothing to get worked up about, but you have wear issues to the chain & sprocket that should be addressed asap.

In all honesty, I don't think even the sprocket looks that bad. Getting close to time for replacement, yes, but as long as the chain isn't stretched beyond the recommended limit, no stuck links, get the surface rust off and clean everything really well, then lube it with a non-sticky spray lube. Check out the teeth on both of your sprockets and make sure they aren't severely hooked. I'd also check your rear swingarm alignment as well; it looks like you might be hitting the side of the sprocket a little heavy with the chain links.
shisoshin and don'tpanic like this.

Tis better to be thought a fool and remain silent, than to open one's mouth and remove all doubt.

On some bikes the rear wheel spacers are not equal. Accidentally reversing the spacers can cause that kind of sprocket wear as well as a damaged/misaligned swing arm.

Thanks, I'll be replacing the chain one the rivet tool arrives in the post.

Replace the sprockets as well... a worn out drive chain should always be replaced along with the sprockets, otherwise you'll just end up with another worn out chain in short order.

Also, looking at your second photo in the opening post, that doesn't look like a typical rusty chain to me. Rather it seems like some sort of road grime that your chain lube is attracting and then it is flinging off the chain and leaving a coating on adjacent parts of the bike. Not sure what that reddish stuff is, but if I had to guess I'd say you maybe live in an area where the road crews use cinders on the roads in the winter months?... that's what it looks like to me.

You also stated in the opening post that you "use plenty of chain wax"... over lubricating the chain can definitely cause more road grime to accumulate on the chain than you want. If you're using a good quality motorcycle specific chain lube, you don't want or need to drench it in the stuff.

Thanks, i'll keep that in mind when lubing the chain.

To me, the red dust looks like it is coming from inside the pin and rollers. I'd say the o-rings are shot and the internal grease is long gone.
