Turner Special
On 16 April 1925 "The Motor Cycle" published drawings by Turner of an OHC single he had designed, using a series of vertically stacked gears to drive the overhead camshaft. A subsequent redesign used bevel gears to drive a vertical camshaft, operating the valves through rockers. The only shared aspects of the two designs were the bore and stroke, 74 mm × 81 mm (2.9 in × 3.2 in), with the barrel being sunk into the crankcases. The head could be removed from either design complete with undisturbed valve gear.
Turner built his first bike in 1927, using his second design, a 350 cc OHC single. The Motor Cycle published a photograph of Turner's patented engine, mounted in his motorcycle called the Turner Special. The Special was registered for road use with the London County Council as YP 9286. It used Webb forks, and a three-speed Sturmey-Archer gearbox.

“We inherit plots.... There are only two or three in the world, five or six at most. We ride them like treadmills.”
—Janette Turner Hospital (b. 1942)
“Here in the U.S., culture is not that delicious panacea which we Europeans consume in a sacramental mental space and which has its own special columns in the newspapers—and in people’s minds. Culture is space, speed, cinema, technology. This culture is authentic, if anything can be said to be authentic.”
—Jean Baudrillard (b. 1929)
