Awesome bikes guys!
My Grandfather was a partner in the creation of the Cyclone Motorcycle in the 19teens in St Paul, Mn. He was the draftsman for the engine. The Cyclone was the first production overhead cam cycle engine and was extremely fast for its day, winning on board tracks and dirt tracks across the country. The effort however was short lived as high production costs, competition and WW1 did them in. We think about 300 bikes were built, including road and track models. 12 are known to remain today, and most of those have replica frames around a Cyclone motor. Here are a few photos. First pic is me and Dad with the owner of one of the few engine/frame numbers matching road models. Still actively being ridden. Second pic is the only known original paint road bike. There is also an original paint race bike out there. Period shot from a team rider. Page from the 1915 sales brochure showing the stripped stock version. Last edited by SMS; 11-26-2020 at 02:30 AM.

Those pics are priceless. Even the mag is shaft/gear driven. Seems way ahead of the time, with all the ball bearings. Too bad the economy killed this.
Those ports at the bottom of the cylinders is how a Detroit Diesel runs, but they are 2 cycle and depend on the blower to force feed air into the cylinder. That engine was very innovative. That improvised sled is really neat too. People would make what they need from what they had back then.
