Seized link. Time for new chain.

Might jump the sprocket or snap off entirely.

Try cleaning the chain properly and relubing it. See if can unfreeze it. You could try replacing the link 8f you have an extra quick connect  chain link

Depending on the chain. What chain is this?

For a sealed chain it's not so much about the frequency of the lube but also how clean you keep the chain.

My factory o ring chain lasted for 20k noisy and stretched to crap but with no seized links.

My current X seal chain has about 32k on it and starting to see signs of wear...with one semi seized link that sometimes frees itself after a good clean and lube. It's due for replacement soon.

Those are standard o ring chains for small capacity bikes. I assume you use a 250.

Chains are not expensive. If you cant free up the seized link after cleaning and relubing, just replace it.

Usually it's recommended to change the chain and sprockets the same time.

My stock sprockets are pretty much done for in about 30k km anyways so I always replace them as a set.

Chain kinks because the chain lube not compatible with the internal grease, or water masuk pass the o-ring and corroded the pins. Could be anything.

At one time, I took out my old kinking chain, put into a pot of engine oil and heat it up. Now I use back, and so far no add chain lube, see how long it will last.

Lol yeah.

Seems only modeski got consistent supply.

Its only the versys 650 or the z900. Even then, I highly question the z900 as a long distance bike. The rear sets are quite high, and the rear pillion seat is small and hard, good, should you plan on torturing your partner.

Honda is hopeless case. Suzuki still has the vstrom 650, and perhaps the very few SV650 that might be still around. Otherwise nothing else in the market.

be careful of your brakes

I'm getting. 18km/l on a yaris at 120 constant. 20km/L at 110. Go figure

Well we have the aerodynamics of a barn door. Plus I'm running risers...so I sit almost bolt upright. Yeah..so FC isn't much to shout about.  I think the big bike with the best fuel economy will be the nc750x. That bike sips fuel.

yeah I think you should change it.
just look for pirelli or michelin good already

do the uneven wear happen on the front tire too?
if only rear tire then might be not aligned properly
if both tire uneven might be how you ride the bike or load it like heavier bag on one side
or yeah maybe its just the road you simply took every day 

check ur fork i rasa sebelah senget hence makan sebelah

I wonder how many of you service the fork ?

I had mine service on the 3rd year of usage.

I serviced mine at 30000km

Not because of leak or issues.
Just serviced it, since I'm using the bike daily.
Clean the internals and changed the fork oil only.
Felt nicer, just like new.

Really?

You might want to find a better mechanic....lolz.

I've gone through 3 fronts on my single disc Dominar in the 2.5 years I had it. They all wear evenly...or in my case, wear unevenly consistently.... Due to the corsa cross x knobbly ish thread.

Unless you really do lefts more aggressively all the time, it seems to be a fork problem, steering cone bearing or your rear is misaligned. Does the bike track straight with no hands on the handlebar? You you sit straight and centre on the bike? I know someone that sits slightly off, basically counter leaning on one side all the time.

Both my front and back wears more to the left, as I tend to take lefts more aggressively...which is normal for our right hand drive roads.
