I´ve owned one for just two and a half weeks -- it was 13-14 days before I had to refuel it. This was the first V-Belt transmission two wheeler that I have owned.
After owning 12 two wheelers since 1967, I´d rate the interior storage space as its biggest asset! . . . . and like Chip 58, trying not to exceed 4000 rpm (TOO often) during the initial 1000km (note that; 1000km NOT 1000 miles . . . see page 5-4 of Owner´s Manual) is difficult. Just try to climb a hill in a metropolitan traffic flow!
