Here's why that might be confusing:
* FMI: This might stand for "Fuel Management Injection" which is a common technology in modern motorcycles. However, it doesn't specify a particular engine type.
* 157: This number could be a model code or a specific engine part number, but without more context, it's impossible to determine what it refers to.
To help me identify the bikes you're looking for, please provide more information:
* Brand: What motorcycle manufacturer are you interested in? (Honda, Yamaha, Ducati, etc.)
* Model: Do you have a specific model name in mind? (CBR600RR, MT-09, Monster 1200, etc.)
* Year: What year range are you interested in?
* Engine Size: What size engine are you looking for? (e.g., 600cc, 1000cc, etc.)
Once you provide more details, I can help you find the bikes that use a specific engine.
