Few machines epitomise the concept of the traditional post war British single better than the BSA B31. The over head valve single was capable of returning over 100 miles to the gallon if handled with a little restraint or, if handled with a degree of enthusiasm, was capable in the words of "The Motor Cycle" road test carried out in 1956 "of maintaining sufficiently fast average speeds to permit large daily mileages to be covered without boredom. Under average conditions use of half throttle gave an indicated speed of 60 to 65mph in top gear". The comfort afforded by the pivoted fork frame and telescopic forks was found to be very good "even when a period of several hours was spent awheel" and "the dual seat was long enough for two medium size riders".
The example offered, dating from the year that the road test quoted from above was carried out, was restored during 2010, at which time all the engine internals were, according to the vendor, renewed. It is described as running "perfectly" and is accompanied by a number of invoices for parts used during the restoration and a Swansea V5C.
