Looking at MTB's

Saw one I liked the look of

But by heck the way the caliper is attached is strange

Looks like you could get rid of most the adaptors and make it much simpler and cleaner?

have a goosey, see what you think?

What's the bike? Looks like whoever built it for the photos doesn't know how to assemble a bike.

In regards to the original question, that does look a completely weird way of mounting the caliper, it's a standard looking RockShox fork, I'm sure you could mount the caliper more conventionally if you ended up buying the bike, unless it is just a messed up build for a press photo.

It's fine, looks like a +40 mm post to post adaptor.

More commonly seen when you want to run big rotors (200/203 mm) on a fork originally intended for a 160 mm rotor.

In this application it looks like it's a 180 mm rotor on a fork designed for 140 mm.

Removing it to make it look neater would require fitting a smaller rotor and dealing with the associated loss of brake performance.

And the missing valve is either photoshop error, or it's hiding behind the fork leg.

Yes so on that fork you would normally expect to see a 160 mm front rotor, the mount adaptor for which would be smaller and neater. For whatever reason the manufacturer has spec'd a 180 mm rotor which needs the slightly ungainly looking adaptor to make it fit.
