The horsepower output of a 1,000cc (cubic centimeter) engine can vary depending on various factors such as the engine's design, technology, tuning, and application. Generally speaking, modern sport motorcycles with 1,000cc engines can produce significant horsepower.
It's worth mentioning that the horsepower output alone does not provide a complete picture of a motorcycle's performance. Other factors such as torque, weight, aerodynamics, and gearing also play significant roles in determining a motorcycle's overall performance and acceleration capabilities.
