Q. What is the difference between FZ-FI and FZ S FI?

Practically if you look from a distance there is no difference between the two bikes. But if you notice closely you will see that the body graphics would be present in FZS Fi V3 which is not there in FZ Fi V3. Also a big difference is that there is engine guard present in FZS Fi V3 which is not there in FZ Fi V3. One more thing is that there is an optional feature for charging point for FZ V3 which is not there in FZS Fi V3, this is secondary.

In FZ-FI V3 u wont get a chrome finishing at petrol tank and a engine cowl. In FZS-FI u get both of those. And FZS-FI comes in three colors whereas in FZ-FI only two colors

Only graphics and engine mud coverOtherwise both bikes are same by engine
