What is the primary danger of driving a motorcycle with worn shock absorbers or leaking fork seals (amortiguadores o retenes de horquilla defectuosos)?

1. The fuel mileage improves slightly
2. Tires bounce uncontrollably over bumps losing road contact, braking distances increase, cornering stability is severely degraded, and leaking oil can contaminate brake pads
3. The motorcycle turns into an electric vehicle
4. The horn sounds louder
