Some vendors don’t list S 1000

I’ve noticed many vendors dont specifically list product compatibility for the RZR S 1000. Typically XP 1000/900 and S 900 are listed on vendors websites but frequently no S 1000. Here’s the question and pardon my ignorance in advance. Is the S 1000 exactly the same as the S 900 just with the larger engine, and different graphics? If I were reviewing shocks for example and a website only listed the S 900 would they be a direct fit to the 1000? What about interior, dash panels, etc?
Thank you in advance, this forum is invaluable for help and education.
