BSA B44 Mitisse 500cc – 1968

The Rickman Metisse frame was the “State of the Art” chassis in the mid to late 1960’s. The BSA B44 engine with Westlake top end was arguably the lightest and most powerful engine available. When mated together, the Rickman B44 was still competitive against the new lightweight CZ’s and Huskies that were the standard in 500cc International GP’s. To this day, in AHRMA (American Historic Racing Motorcycle Association) events, several competitors prefer this motorcycle because of its tractable power, lightweight (for a 4-stroke), and precise handling.

This machine was built by my friend, Frans Munsters of Veghal, Holland. Frans, the founder of the leading motocross air filter company, Twin Air is a collector and restorer of vintage dirt bikes. This machine is one of four bikes that I have purchased from him and imported into America.
