Is it a motorcycle? Is it a car? Every once in a while, someone builds a vehicle that forces those who see it to ask those two questions, or reasonable facsimiles thereof. In the 1970s, the Quasar was there to prompt that question; first as a concept, then later as a 'production' motorbike. I'm putting 'production' in quotes because the total number made by the end only just got into the double digits.
Most of them were as British as could be, and the first 21 reportedly repurposed engines from Reliant Robins. They were shaft-driven, and included features like a hot-air blower for the handlebars, hydraulic disc brakes all around, leading link front suspension, a reclining (!) leather seat that placed the rider's feet forward, a lockable luggage compartment with a two cubic foot capacity, and of course what Quasar's designers said was a very aerodynamic "up-and-over fairing."
How aerodynamic, exactly? One could allegedly do over 100 mph whilst operating a Quasar, and the whole point was to be able to do it in a sustained, comfortable fashion, such as one might encounter if one was to take their Quasar on a motorway for an extended period of time and not get stuck in traffic.
