Funny that Suzuki's 1983 Katana had some vague similarities. I almost purchased this bike, but the engine had 17 less horsepower than mine. A beautiful bike, the fairing and seat/side covers were designed in Germany. My bike (GS750ES) has a full floating mono-shock suspension, anti-dive front forks, weighed 40 lbs less and had 17 more horsepower and 16 inch front wheel, which would kill a novice rider, but is like a scalpel, slicing the roads ,in the hands of a skilled rider, like a skilled surgeon, slicing his way through. My GS750ES does things I could never getaway with on other motorcycles, Still have and ride it, since 1983.
These TV shows could have incorporated wheeled vehicles, as most societies they visited would have had them, it could have made the plots more open to variability, instead of the sandy, road-less settlements they always landed near, and had to walk 5 miles to get through. I agree with your TNG analysis. One of Voyager's best was "The year from Hell", with the "Krenim" time machine. DS-9 had a beginning and end, which makes in so worthy of syndication.
You can see the cylinder head from the dirt bike they based on the BSG motorcycle on, though I would not fly on such a thing without some kind of harness to hold me on, and a ballistic recovery parachute!!
Bates made a very similar fairing for street motorcycles back then.
Katana 750, a beautiful, highly collectible motorcycle.
1983 GS750ES w/ rare fairing lowers, I purchased the only set I have ever seen.
