Buying advice Sportster 1200

Hello together, I wanted to buy a motorcycle in August and had thought about a used Harley Sportster 1200. After everything I have read, I think the 883er will be to “lahm”. What should I pay attention to when buying? Is there the Harley also with Kardan drive (is the question too heretical 😉 )) and can you recommend me a Harley dealer in my area where the service is right and you could buy a used one. As already said I wanted to “truck” so in August. Thank you in advance for your answers. Greetings Raul
