That's an MV F4 Senna. As I recall, it's the only actual Senna out there. What I mean is that while Monsters come in a Senna color scheme, the MV is the only bike to be actually called a Senna. So, what's in a name? Well, the bike is named after a Brazilian F1 driver named Aryton Senna who died during a race in 1994. Pretty expensive bike, you may in fact have to sell a kidney!
