Re: 100-year-old Brit Gets Famous. Has Had The Motorcycle Affliction.
We've all seen the "Grapes of Wrath" scenes of steam coming out of the radiator caps of cars of that era. I'm not sure when they began pressurizing cooling systems............30s?..40s? And not sure if a water pump was used before pressurized systems as the thermo-siphon method wouldn't need one?
So I'm guessing the unusual water-cooled Scott (most motorcycles were air-cooled) just followed the car cooling designs of the time.
