From a purely technical perspective, surface rust on the outside of the chain links will do nothing untoward, and neither will rust on that area of disk. Cosmetically, they look scruffy, but aren't the end of the world.
The inside face of the chain looks pretty dry so maybe you need to look at how you are protecting it, but the important parts are those that move against each other and the sprocket, not so much the outside faces.
Remember that Suzuki and salt don't get on very well and there's other parts that are prone to corrosion that aren't meant to be changed so it's important to make sure you properly wash it if you want to keep the rust at bay.
