It is a standing joke when Deb and I travel, that if there is a back up in the left lane of an Interstate highway, the odds are even that when we get to the offender, it will be a Prius going one mile an hour over the posted limit; lounging in the left lane. We even have a shorthand comment for them: P3L (Prius Left Lane Lounger).

Marusho ST/Magnum 500 circa 1967. But the turn signals were added?

The liquid is actually some kind of water absorbent polymer that is expanding in volume at each pour. Notice the thick sludge remaining in the first glass as he tries to shake the contents out of the first glass into the second glass and so on. Probably one of those cornstarch based "super slurpers" as used in disposable baby diapers. http://www.ars.usda.gov/is/pr/2006/061205.htm

Good luck with this one:

1976 Kawasaki KH500

Well, you asked for it. Don't blame me for ocular damage.

Luxury.

Well, I got the prototype and the MZ, so this is for the next guy.

MZ Saxon 251

It is an Audi ZR 02. Just one was built. In 1976. Had an Audi 50 1300cc engine. http://beforeitsnews.com/motor-junkies/2013/11/audi-zr-02-concept-motorcycle-2482070.html

Right back at ya.

Major manufacturer's one off show bike.

1903 Buchet http://i1125.photobucket.com/albums/l582/rrosco/Buchet_zpsb6baeca1.jpg

Not exactly a household name here in the U.S.

Matchless 8hp, 1000cc Motorcycle and Vickers machine gun armed sidecar. Ordered in 1916 by the Russian Government, built in 1917 and were never shipped owing to the revolution, so taken up by the Motor Machine Gun Corps of the British Army instead. It's the only Matchless Motorcycle + Vickers combo left (there are two others - both Clyno's, one at the National Motorcycle Museum and one in storage owned by the Imperial War Museum), and of the three motorcycle machine gun combos left, it's the only one running.http://i282.photobucket.com/albums/kk256/RobLangham/New%20album/a7-2.jpghttp://landships.activeboard.com/mobile.spark?p=topic&topic=49864019

Around one hundred built.

1943 FN Socovel, electric scooter from Belgium.

Like I said, "be precise" with the description. So which of the above is your answer? Because it ain't fair to "shotgun" it with all the descriptions and all the years. What year and model (precisely) is the pictured bike?

Because this is not especially difficult, you must be precise in your description:

Morbidelli V8, circa 1994.

As like the previous motorcycle, this bike was rarely sold outside its country of origin.

Chinese Donghai 750A circa 1980http://upload.wikimedia.org/wikipedia/commons/0/04/Donghai_gr%C3%BCn_Seite.jpg http://upload.wikimedia.org/wikipedia/commons/b/b7/Donghai_750_solo_links.JPG

No, adjusted properly, the First Gen intercom utilizes a VOX (voice activated) microphone. Simply speak, and the passenger and operator microphones are activated. A nice plus for the First Gen over the second Generation. You do have to use the PTT button to speak on the CB.
