* Engine type: A 200cc single-cylinder, two-stroke engine will produce significantly less horsepower than a 200cc four-stroke, multi-cylinder engine (if such a configuration even existed at that displacement). Two-strokes are generally more powerful for their displacement but less efficient and cleaner.
* Design and Technology: The design of the engine (camshaft type, valves, fuel injection system, etc.) significantly impacts power output. Modern engines with advanced technologies will produce more horsepower than older designs.
* Tuning: An engine can be tuned to increase or decrease horsepower. A race-tuned 200cc engine will have far more horsepower than a stock engine designed for fuel efficiency.
You might see 200cc engines ranging from roughly 10-30 horsepower, depending on these factors. To find the horsepower of a *specific* 200cc engine, you'd need to consult the manufacturer's specifications or a reliable source of technical data for that exact engine model.
