There is something very imposing about the 80 m.p.h. Coventry Victor. In the same way as a semi-stripped 250 c.c. or 350 c.c. machine may be likened to a torpedo-boat destroyer of the road, the big flat-twin under review may be called a Dreadnought. It has fairly full touring equipment, adequate mudguards, large tyres, and a 2½ galls, capacity saddle tank. Technically, the most interesting feature about the engine (which follows standard lines except for a higher compression ratio and a modified valve gear) is the induction system. Two carburetters are employed, and a valve-controlled air inlet funnel faces forward. Air pressures in the induction pipe, both float chambers, and the fuel tank are balanced by connecting pipes, thus ensuring that a uniform flow of petrol takes place at the jets at all speeds, and irrespective of jars caused by road inequalities.

An interesting detail refinement on this model is an aluminium undershield which also serves as a front stand. An addition of £5 to the list price is made for the 80 m.p.h. guarantee.

On a standard sports model, also shown, only one Cox carburetter is employed; the tank is not of the saddle variety, and the tyre is 28x2½in.

Touring types (one called the "Grey Ghost" and finished in grey) with and without the Holt spring wheel sidecar complete the exhibit. The prices are: De Luxe touring solo £100, with Holt sidecar, £125; standard touring or sports solo £97 10s., with sidecar £119.

The long wheelbase model has been discontinued.
