NSU 351 OT motorcycle, 1937


The 351 OT appeared in 1935 as an extension of the OSL series. With the same suspension as the 251 OSL but with a more powerful, bored out engine, it was especially suitable for use in mountainous areas and for passenger and side-car operations. It was characterised by low fuel consumption and a reasonable selling price.

Displacement: 331 cc
Power: 12.5 hp at 5,020 rpm
