The Cyclone had a very new concept with an OHC (Over Head Camshaft) system that significantly reduced the number of mechanical transfers. This model was timed on track at over 170 km / h, breaking the speed record very far ahead of Indian and Excelsior. It was not until 1925 that a Brough Superior SS100 could go faster.
At all times, competition is expensive. The mechanical parts of the Cyclone were fragile. The Joerns Motor Manufacturing Company was not interested in industrialization and investment and had to cease its operations as early as 1916. No US constructor tried to continue their OHC V-engine concept that had been so promising.
Only six units of the Cyclone survive. One of them, made in 1915, painted in yellow canary which was the signature color of the brand, was bought by its current owner in 1984 in the auction of the Steve McQueen estate. This bike is estimated $ 650K for sale by Mecum in Las Vegas on March 21, lot S57.
