The CR5 is pretty much a version of the Loncin Rover.

Its cost effective for them to make this model if it share parts with another existing model.
Loncin seems to be adopting a naming convention for their bikes the 650 is being referred to as a CR9.
Who knows maybe there are models in the works to fill the in the missing numbers between the CR5 and CR9?
