Sunbeam 1928 492 cc cc side valve, frame E 2756 engine J 2757
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.
This “ Light Tourist” is equipped with a “Longstroke” engine and also has the characteristic fully enclosed rear chain.
Front mudguard is non-original.
