If you’re looking for a three-wheeled motorcycle, there is only one out there that is available as a factory product. The Harley Davidson trike. Which, of course, has it’s wheels set up in the reverse manner from what you’re describing. Which is the only way that you get a three-wheeler that’s still a motorcycle.
I am 55 years old and have been riding since I am 5 years old. My wife and I love to ride but two wheels no longer fit our riding needs which was a ultra Dresser, soooo we decided to purchase a trike to continue our riding for many years to come. Thank you Harley Davidson for manufacturing such a great trike motorcycles.
