For the setup to work, you'd need to replace the shifter and derailleur. The shifter is needed to get the right number of clicks and correct cable pull between gears, and derailleur is needed because the Shimano changed the actuation ratio between 9 and 11 speeds.

Why would you want to use a 9-s cassette? If your bike is 11-s the drive-train will not work and the chain is much too narrow. The indexing is wrong. It can't be adjusted because the spacing between the cogs is different in both systems. The wider 9-s chain might even destroy your RD by getting stuck in the derailleur cage. Get an 11-speed cassette and you ...

As mentioned in another answer, the main purpose of half link chains is to have more control over the chain length and hence the wheelbase of your bike (assuming you have rear facing or slideable drop-outs). A centimetre difference in wheelbase will change the feel of the bike quite a bit, especially on a short bike like a BMX. Half link chains can only be ...

Having a chain that's slightly too long or slightly too short may also worsen the quality of shifting. A chain that's too short will pull the jockey wheels a bit further away from the cog. The drivetrain manufacturer presumably designed their derailleurs with a certain optimal distance. The issue is how quickly shifting degrades as you move slightly away ...

The main problem with a chain that is too short, is when you're in a combination of gears where the chain is too short to go around both chainring and cog. You'd have to be moving the chain from a lower to a higher-tooth count gear, so at some point in that first half-revolution, the chain will bind, the cranks will resist you, and any more force on the ...

The KMC X8 has, I think, nickel plated outer links. Doesn't matter except for looks. The plating of outer links is not what wears in chains. Other than that, it claims to have mushroomed rivets Every chain today has "mushroomed" rivets. These rivets prevent joining the chain again with its own rivets, a clear drawback. However, they make ...

Actually for the record the 5,6,7,8 speed derailleur chain is 3/32” wide, ie just 1/32” narrower than the single speed chain which is 1/8” (or 4/32”) wide. Jeez, I love metric instead of all this mumbo jumbo!

The main problem is quality, in terms of dimensions and variance. If you think its an 11 speed chain but someone has just repackaged some 10 speed chain, then there will be issues. Likewise, if it were the right chain but didn't pass Quality Control and was rejected because it didn't match the required dimensions, then it could fail quicker, or accelerate ...

You can normally use chains from other legitimate vendors, be it SRAM or KMC or something else. You do not need to use Shimano™® chains only. But no-one can tell you whether your chain is of sufficient quality. Only you can inspect it, measure it and try it. We cannot do that. I am not even 100% convinced it is actually a fake chain, but I will just take is ...
