Ruttman Wild Goose info request

#1
I recently bought a Ruttman Wild Goose 250. I was doing some research and found some brochure pictures. I did some screen prints from the computer on them. They have conflicting info. Could the discrepancy's be from different years?

The differences is in Wheel and Tire size and gearing (Along with overall minibike dimensions because of tire size).

One has 5" rims and the other 6" rims. Does anyone have any input on this info?
Here are the two screen shots of the info.
