A Yamaha VIN generally follows the following structure:
JYA - Manufacturer Code
1FG - Model Code
003 - Year Code
FA - Assembly Plant Code
001458 - Serial Number
The Model Code section, in this case "1FG," can provide information about the specific motor. However, it might not directly indicate the motor letter (N, S, X, etc.). You may need to refer to additional sources or consult with a knowledgeable Yamaha expert to understand the exact motor type based on the VIN.
It is also worth noting that the model codes and VIN formats may vary depending on the specific year and region of the motorcycle. For more precise and accurate information, it is recommended to verify with official Yamaha documentation, authorized service centers, or reputable online resources specializing in Yamaha motorcycles.
