nope, I have special issue of Racer uk mag on my lap, and it's got pictures of all 8 of the top tourers, and that aint a CGM....
Gearbox casings are all different, as are the chassis struts.
I think the biggest change would be in the steering, but can't really see the changes to the suspension, given the blurryness of the picture, and that it has wheels on...
