The Wolverhampton based firm of John Marston earned fame for their superb bicycles in the early years of the last century. 
In 1912 their first motorcycle was presented, a 350 cc  side valve model ( 75x 79 bore and stroke) with a 2-speed gearbox. 
Soon the capacity was increased to 500cc, and also models with proprietary V-twin engines were made.  
Sunbeam motorcycles gained fame for their very high standards of workmanship, their speed and their reliability:  races all over Europe were won in the early half of the twenties  with machines equipped with the very fast and reliable  “ Longstroke” side valve  engine with bore/stroke of 77x 105.5 mm. In June 1930 the Longstroke model was restyled, it got bought-in welded steel petrol and oil tanks. It was designated “ Lion” because the Lion was one of the ICI trademarks. 
From September 1930 all Sunbeams got the new Webb-type front forks with centre spring.
In  the course of 1931 a 598 cc version of the Lion  became available. 
This machine had dimensions of 85×105.5 mm.
This reliable, high quality Sunbeam tourer is very suitable for vintage rallies. 
It is equipped with Lucas electrics and is well  restored.
