The oil filter is just one of the many little fun facts about this Italian machine. Spoked wheels with tubeless tire, spokes are on the outside of the rim and a real ***** to clean. Front and rear brakes are linked, stops on a dime. Will not run on the side stand it all, has to be in the upright position. Has fuel injection and a choke, really just a throttle control. Front forks are adjustable like a sport bike. It's like having alzheimers, you learn new things everyday. I will to say, it is true blast to ride, fit and finish are not the best quality but from what I understand the motors are bullet proof.........
