I hear ya. I've got the worlds only 2010 VFR800 also.
Replacement frames from Honda are blank and bear no VIN, so I had to apply for a VIN tag, and a nice ex-RCMP officer came to my house (!) and filled out some paperwork in order to give me a little metal plate, which he rivited to my new frame.
Mainly they are concerned about bike theft, and trying to disguise stolen parts, so I had to produce the original invoice for the replacement frame from Honda. $1142 and change.
After that, I needed a salvage inspection before I could get insurance and registration. Definitely took the long route on that deal. But, I've got the bike I want now. So it was mostly worth it.
Up until a couple years ago all used bikes over 400cc here had to have the serial/VIN and the engine numbers verified before you could register it. They have since dropped it because they didn't catch any stolen bikes or engines in all the years they did it. It is possible that was because they had the program in place? They told me all it did was inconvenience customers and tie up their resources.
If the frame does not have a serial number here you would not be able to register it. The idea is that they don't want billy-bob building a frame from god knows what. They used to have the police inspect numberless frames and attach a plate if needed like you had done, but that has been dropped. The province doesn't want to deal with such matters so they just say no.
They didn't attach any plates or anything to my frame as they accepted the original number plate as proof of an "engineered frame". It is strange that with a new frame I would have been SOL, but logic is not always the driving force in these matters.
That is cheap for a Honda frame. American Honda still has some RC30 frames and they are around $2300. Honda can be weird about selling frames, they usually want a registration and ownership info before they sell one. Nobody else does this that I know of.
