Just spent a considerable time browsing this site as a new purchaser and owner of a 1955 M21. I have restored a 1958 Tiger Cub and a 1960 BSA C15 and am now moving up! The M21 is having to be a nut and bolt job so I have a feeling will be using here quite a lot!!! My impressions are that this is the best single bike dedicated site I have seen. Friendly, informative, no ridiculous forms to fill in and links to follow. Really impressed.
