Sunbeam introduced overhead-valve engines in the mid-1920s having established its not inconsiderable sporting credentials with sidevalve machines. The Wolverhampton concern missed the virtually wholesale switchover from flat-tank to saddle-tank frames for the 1928 season, and its saddle-tank models did not appear until September of that year. Changes to the OHV engine were confined mainly to its top-end. Early flat-tankers featured a straight-ahead exhaust port, a peculiarity which necessitated the adoption of a bifurcated down-tube, then later in the 1920s the fashionable twin-port cylinder head became an option before Sunbeam standardised a single-port design in 1934. Pushrod enclosure had arrived by 1930 to be followed a couple of years later by partial enclosure of the rocker gear.

This post-Vintage example of Sunbeam's overhead-valve Model 8 was purchased by the private vendor from Vintage & Veteran in 2019 where the machine has been used sparingly since acquisition. The HPI and V5C state that the Sunbeam was previously registered overseas (it was first registered in the UK in 1972) and whilst in the UK has had 7 previous owners. The machine had already been restored when the vendor purchased it. Related bills for parts and services are on file and the Sunbeam also comes with the aforementioned HPI/ V5C and instruction manuals.
