While the model name decal does not appear to have been tampered with, it does more closely resemble a 1982-1983 Mirage Sport. Motobecane wasn't very widely distributed in Canada compared to the USA, so I don't have any Canadian literature from this period and I'm wondering if the differences are related to Canadian versus USA models. There were certainly differences between the two markets for other French marques of this era, such as Peugeot.
