I think those are both the real deal.
First one has some nice add-ons. Higher mileage would be fine if it was well taken care in the maintainence dept., with records. That belly pan is nice, wish I knew how to get one of those attached to the OEM lowers.
Second one looks to have an adjustable steering head which would be indicative of an 's' in the '99 MY, I believe. Somewhere in '97, '98, or '99 the adj. steering head was changed as a std feature on all 748 models, to a 748s only feature. Doesn't look like it's been ridden hard by the looks of the rear tire, but that may be new.
Just have to see where the reserves end up as to whether either one of them would be a good deal.
