Can you put a Yamaha Zuma 125 engine in a Yamaha Zuma 50 frame?

While it's theoretically possible to fit a Yamaha Zuma 125 engine into a Yamaha Zuma 50 frame, it would require significant modifications. The frame, suspension, and braking systems may not be designed to handle the increased power and weight of the 125 engine, leading to potential safety issues. Additionally, you would need to address compatibility with wiring, exhaust, and fuel systems. It's generally recommended to use the engine designed for the specific frame to ensure proper performance and safety.
