I've rode the Busa in lower 40 degree temps a few times, no problems. I've rode other bikes in 30 and even upper 20 degree temps, no problems. Normal air pressures and don't get crazy in the first 2 or 3 miles. I don't like riding in cold weather because it's cold, and I don't like having to bundle on so many layers I can barely zip my jacket. Bike works fine, it's me that doesn't handle well in the cold.
