The Rickman brothers were well-known in many circles for the precise frames that they produced for both on and off-road use. They offered a series of generic frames and they typically supplied engine plates to bolt in an engine of your choice. It was very rare to see a Hodaka powered one in the lineup. They were extremely reliable, small displacement engines. Very few were fitted with Hodaka engines. Typically, they were sold with a small Zundapp 125 engine.
