the 85&9540 are built on the same chassis....I had the 7040 then upgraded to 8540....unfortunately, I've got a small frame (personally) so I can't rightly compare....but in terms of features, the 85 is a big step above the 7040....the wheel size on the 95 is slightly bigger that the 85 though both sizes are compatible with each model....go with larger wheel size if you get the 85....sorry can't help w/your fit, seems that 6'2" should not be a problem unless you've got real long legs.....good luck! bb
