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.
