I am hoping to connect with some Rickman CR 900 experts / enthusiasts.
I have recently added a very nice 75 CR 900 to my collection and hope to find out if there is still a Rickman CR club in existence and parts vendors.
Also I am trying to piece together some interesting history about this bike. It was built by Boston Cycle in 75 (they appear to be out of business now)
I have the original invoices from Boston Cycle to the fellow who bought it and ordered some engine upgrades. Not sure if I should post his name here and cant find him either. I would love to know more about its history and something specific to to this frame number. Any help appreciated.
