Nice.  

Looks like it could have been sitting at the back of the dealer's showroom and dusted off for a sale.

Nice.  

Are those tail bags BMW or aftermarket?

Nice bike . Those are BMW bags they should also have a plastic cover.

So that kit even came with a tank bag and the tank bag brackets.

I tried the tank bag with the extension installed once on my K1. With the K1 leaned over riding position the chin of my helmet would hit the top of the tank bag. It was annoying when I turned my head. 

Yes OEM bags with plastic cover for the tank bag. 38K miles. It’s been stored indoors for 10 years. The paint has a few cracks showing the original red underneath. Got a good deal on it because the last ride it went on the final drive developed a very loud clunking noise. I haven’t looked yet but I assume it’s the drive shaft/u joint.
When I got my 84 K100rs it to had been stored for a few a years and I had to replace most of the rubber parts, hoses and intakes, so I have some work to do.
I do wonder if my 84 is actually an 83 ? VIN 10114 I was told the original owner was in the U.S. Army in Germany, bought it and had it shipped over here. Before K bikes were even available here in the U.S.

If the last seven digits of the VIN are 0010114, then it's a 10th month of '83 (Euro-spec K100RS) which makes it a 1984 model.

Euro-spec ? Different cam ? 10 more hp ?
I can turn my headlight off/on

Euro-spec simply means it was not intended for the US market, there might be a deleted tank vent system in those early years, km/h instead of mph, a headlight switch is an added bonus, rumours abound about 'hotter' cams with no definitive answer, but certainly no discoverable real world horsepower, maybe some non-US colour options. Really that's about it.
