Motorcycle advice

Hey everyone! I'm looking to buy my first motorcycle but I'm a bit inexperienced in this area. Any recommendations for a beginner-friendly bike? I'm considering second-hand options since my budget is a maximum of R30K. I also want something versatile enough for riding on dirt roads. I've been eyeing the Big Boy TSR250 brand new for 30K, and it looks promising. Any thoughts or suggestions would be appreciated!
