Maintenance was a mixed bag. With the airbox sandwiched between the engine and gas tank, and the seat having to come off first, getting to the air filter is a chore, particularly if you misplace the little wire thingamajig that holds the tank up out of the way. But once you get to the filter it comes right out, and its flat, square shape makes it easy to clean, lube and replace. Moreover, because the air intakes are high up behind the radiator shrouds, the filter doesn't live in the dirt thrown up by the rear tire, so it gets less dirty. You really don't have to clean it after every ride.
