Within your budget, bikes like the TVS Ronin, Royal Enfield Hunter/Bullet/Classic, Triumph Speed 400, Harley-Davidson X440, as well as the Honda CB350 models, will make for a good fit in the neo-retro roadster segment. If you want something that’s a little more rugged, then ADV bikes like the TVS Apache RTX 300, Hero Xpulse 210, and KTM 250 Adventure deserve your attention.
A test ride of all these should help you decide which is the best option for your usage as well as your physique.
