link doesn't work for me (and probably the rest of us who don't live in canada).
It could be a baby Supersport - there was a cb400 that honda made that was just like their 79-82 cb750/900/1100 supersport - same paint colors and everything. Very rare in the states but kinda common in canada. Stock colors would be silver with blue stripes. More than once have I bought bodywork thinking it was DOHC cb750F stuff only to get it home and find it was just a wee too small.
