During the 1930s BSA concentrated on producing an extensive and varied range of dependable, well-made and competitively priced motorcycles. The majority of these were singles but for the sidecar market BSA offered the Model G 985cc sidevalve v-twin and, for the more sportingly inclined rider, a smaller overhead-valve v-twin, the 499cc Model J. Somewhat surprisingly, given its complexity, the newcomer had originally been developed for the War Office. Predictably, it was rejected by the latter, which tended to favour sidevalve singles for military use, and appeared for the first time in civilian guise in the 1934 range as the J34-11. Typed J35-12 the following year, it was joined by a 750cc version, the Y13, before ceasing production at the end of 1936 as the J12. Although the '500' had gone, the 750cc v-twin continued until the end of the 1938 season. The model featured twin exhausts on the right-hand side to facilitate attachment of a sidecar. Produced for only three years, the handsome Y13 is today one of the rarest and most sought after of all 1930s BSAs.
Our vendor purchased this Y13 in 1965 when he was aged 19 (at which time it was in the 'Sidecar Bicycle' taxation class) and used it for only a couple of occasions before consigning it to storage due to family and work commitments at the time. The machine was subsequently dismantled and kept at the vendor's home. In 1980 he started the restoration but never completed it. In 2007 the machine was reassembled and sent to Newton & Smyl (Ned Smyl) in Belmont, Surrey, for finishing and a complete check over (Ned had the BSA for 4-5 years as it was not considered a priority). Since then the machine has been kept in the owner's garage and is now offered in need of recommissioning and/or more extensive restoration prior to further use. Sold strictly was viewed, this beautiful BSA Y13 comes with a file containing an old continuation logbook; photocopies of marque-related literature; magazine article; Armour Motor Products catalogue; instruction manual; reproduction spare parts list; current V5C document; and a quantity of restoration invoices dating from the 1980s. Key not required.
