Bit of a late reply I know, but I might be able to help, as I have a FZR400 RR SP EXUP
Try jap4performance to find some different fairings, I think there might be some conversions on there but I'm not sure. Do your lights have red rings around them? If so then its an EXUP.
The numbering is the specific model, which seems unimportant but when you're looking for parts you'll have to make sure you know it or they won't fit. The last few letters of your VIN number is the model.
Different models are likely to have different wheels, like I said you really have to know what model yours is.
And the Deltabox is the Aluminium frame
Hope thats helpful.
