1931 Ariel SG31 Sloper 500cc 4 Valve, WXG258
An extremely desirable & very rare 4 valve sloper (only being manufactured by Ariel for two years), which left the factory on the 31st of January 1931. This machine still bears its original frame & engine numbers, & has undergone considerable refurbishment over the last few years.
