History/Production:Entering the market when multi cylinder, large capacity, angular shaped bikes were all the rage, Honda set out to build a single cylinder (“thumper”) 1950’s style “café racer” taking in design elements of the period such as the BSA Goldstar Clubman, the Norton Manx and the Velocette Venom. While a moderate success in Japan, US sales were hindered by the American love of large engines and a dislike for high prices. Consequently, it was built for just 2 years. Due to its classic proportions (subsequently popular) and very limited production run, today it is considered a cult bike and a rapidly appreciating collectible. Powered by a modified, smooth running dirt bike single, the only obvious accommodation to modern times were the single front disk brake and turn signals.

Production numbers are unknown. It is believed 2000 went to the USA with 1000 of these being re-exported to Europe, particularly England and Germany. 1700 were sold in Japan. There were also limited exports to Australia and New Zealand but numbers while undoubtedly small, are unknown.
