At 10,000 miles I swapped plugs, swapped to a K&N air filter, and swapped chain & sprockets. That's about all as far as REQUIRED maintenance. I've changed the oil every 3500 miles and used a genuine suzuki filter and castrol full syn 4T. Tires when needed. Brake pads have been changed once, although I really just wanted to try double H sintered brake pads. I'm about due for new pads and chain+sprockets.
