The Harley-Davidson X440 is built by Hero and is a simple motorcycle without too many complex parts or features. As such, it should largely be a decently affordable machine to live with by and large. Resale value is very subjective and is sensitive to the area you reside in, as well as a multitude of other factors.
If you want something similar, bikes like the Honda CB350 models, Royal Enfield Meteor 350 and Triumph Speed 400 make for promising alternatives.
Take a test ride before you decide to see which one fits you best.
