If you have short cranks, brakes, and fat tires, riding stairs isn't that bad. The main things you have to worry about are pedal strike regulating your speed. My commuter bike is set up with 37mm tires and a front brake and I have no qualms about taking a staircase or two. I would not do it on my track bike though. Your karate monkey should have no problem.
