Description

1973 BSA 499cc Victor B50MX

BSA enjoyed great success with their off-road machines. When they upped the capacity of the B40 to 440cc for the B44 range, Jeff Smith used it to great effect in scrambles competition, winning the World Motocross Championship in 1964 and 1965. In the late 1960s, they increased capacity and power again for the 500cc B50 range. One of these was the Victor B50MX.

Introduced in 1971, the B50MX turned out to be the last competition motorcycle announced by BSA, just as the financially strapped company’s efforts were drawing to a close. It was a truly great design. Its development was driven by the great success of BSA’s works machines in international motocross, with a heavily beefed-up engine in a completely new chassis with an oil-bearing frame, so-called ‘Slimline’ forks and conical brakes. The B50MX made for an excellent motocrosser of which, sadly, relatively few were made. Unless approached with caution, it “was capable of putting a little mud in your eye, a little grey in your beard, and a little steel in your shin”.

The motorbike offered

The 1973 BSA 499cc Victor B50MX on offer here was part of a collection with a focus on off-roaders, a nod to the desert racing of the owner’s youth. Restored to excellent condition by Wayne Sumner, the bike is well-presented. Reportedly a ground up restoration including engine rebuild with attention given to a cycle parts. Having been on static display for some time, the bike will need the usual re-commissioning before returning to its off-road playground duties.

Sold on a Bill of Sale.
