In general, comparing engines solely based on displacement (cc) and assuming the same RPM is a simplified approach. While displacement is an important factor in determining engine power, it is not the sole determinant. Other factors such as design, compression ratio, fuel system, and overall efficiency also play crucial roles in determining an engine's power output.
This is because the dual-cylinder engine has two separate combustion chambers, allowing for a more efficient burning of fuel and air mixture, leading to increased power output.
Having two cylinders also allows for better balance and reduced vibration compared to a single-cylinder engine, which can further enhance performance. Additionally, the dual-cylinder engine may have other design improvements and optimizations specific to its configuration, which could contribute to higher power output.
It's important to note that this is a general comparison, and actual power output can vary depending on various factors specific to the engine's design and engineering.
