my ancient uncle and auntie came round yesterday for lunch. They were spritely things ip to about ten years ago. Time is now starting to take its toll. Anyway.. we were talking bikes (he had an endless series from the 40's onward) and he was ogling my shed of projects and the Suzuki's and his eyes lit up as he described awesome bikes from a wild and distant past. He became more and more animated and those replacement joints were waving with excitement. One bike from the early 70's obviously made its mark.
After a while listening and joining the dots I was able to give it a name - MAICO 440.
