The Norton ES2 represents one of the great overhead-valve singles of the vintage motorcycle era. Introduced in the mid-1920s, the 500cc pushrod engine became renowned for its dependable “slogging power,” smooth torque delivery, and remarkable fuel economy—often achieving 80–90 mpg. Its enduring design later formed the foundation for Norton’s celebrated ES2 models of the 1950s.

This particular machine, produced in 1928, carries the distinctive Norton saddle tank with knee grips, girder front forks, and a sprung saddle in place of rear suspension. The frame incorporates lugs for sidecar mounting, reflecting its period versatility. Large drum brakes provide strong stopping power for the era, while the half-gallon oil tank with mechanical Pilgrim pump and auxiliary hand plunger supply reliable lubrication. A valve lifter eases starting by reducing compression.

Originally fitted with a hand-change gearbox, this example was later upgraded to a foot-change mechanism, a common modification that greatly improved usability.

This Norton was long owned by Ed Hewitt, who acquired it after his AJS and used it as his regular road bike through the 1960s and 70s. Its relatively low saddle height suited him at 5’4”, though he often required assistance to start it—a charming reminder of the era’s demands on riders.

The motorcycle has been off the road for roughly three decades and will require recommissioning, including cable inspection, lubrication, and attention to tires, brakes, and steering. While it currently lacks lighting equipment, a period gas headlamp and taillight could be added to complete its specification.

Guide Price: $19,400 – $23,400
