Welcome to the forum and a great choice of bike. Yes they are very economical bikes and glad your enjoying it. Suspension I think is adequate for normal street riding and yes it's adjusteable to a degree, but make sure it's adjusted for sag and set up for you. I find for normal and some spirited riding it is fine, however the rear certainly isn't perfect. I am sure others that have changed their suspension will have information for you.
Welcome again mate
