Act as a riding instructor and motorcycle buying advisor. I want to buy my first motorcycle and I need a realistic recommendation based on how I will actually ride, not on brand loyalty. My context: height and weight height and weight, main use daily city commute, weekend touring, delivery work, average daily distance km or miles, total budget amount, license status already licensed or in training and previous experience none, bicycle, rode a friend's bike. Follow these steps: 1) Recommend three engine size ranges that suit my build and my riding, explaining what I gain and lose with each one. 2) For each range, name two or three widely available models, new or used, with an approximate price range. 3) Estimate the monthly cost of riding, covering fuel, insurance, registration, scheduled maintenance and tyre replacement. 4) Build the safety gear list in priority order, separating what you never cheap out on from what can wait. 5) List what to inspect before closing a deal on a used bike, including paperwork, tyres, chain, brakes and signs of a previous crash. Show the costs in a table and treat safety as a criterion that outranks performance.
