United Motors doesn’t produce their own motorcycles. They import and sell Hyosung bikes to the US. Hyosung is a Korean brand right now that is considered a very risky buy as their dealership and parts network is practically nonexistent. Many people have complained of not being able to get their “under warranty” bikes fixed simply becuase the parts needed to fix the problem aren’t available even to dealerships. And their reliability is a bit more spotty than the more well known brands. Models with Digital/LED dashes are known for losing the entire dash.
This is all information I learned from a friend of mine who is a technician at a dealership that used to sell Hyosung motorcycles but stopped carrying the brand because they were unable to honor warranties on bikes they sold due to lack of parts availability.
