When the model year was a little old, there were a lot of changes, but I was able to ride comfortably without seeing any problems with the engine. Because it is a Yuni Yusha, I am worried about the cost of maintenance. Perhaps it would have been a little easier if the repair could be repaired in-house. Since the model year is old, I can't deny the feeling that the suspension around it is a little heavy. The engine blows up and the engine sound is comfortable. The tires were so kind of noise that I felt uncomfortable.
