With the introduction of the Multi Gear Rudge were far ahead of   their competitors. 
The firm won the 1914 TT races with this system and Rudges were subsequently barred from certain speed events because of their “unfair head start”. 
The factory turned this to their advantage by using the “barred” logo in a clever company advertising campaign. 
The Multi Gear system is based on the possibility to vary the diameters of both front and rear pullies, like the well-known Daf Variomatic system. 
By moving a long lever alongside the petrol tank about 18 different gear ratios can be selected. 
While on the move the rider can choose the engine rpm that gives most engine torque and then he can raise the actual speed of the machine by changing the gear ratio with the “ multi- lever “ without actually raising the engine rpm, a remarkable experience when being out on a multi for the first time. 
The standard Multi has bore and stroke of 85 x 88 mm  but this model comes with a huge stroke of 132 mm; the powerful long stroke engine makes the machine very suitable for sidecar work. 
The lubrication of the engine is effected by depressing the pedal below the right footrest. 
The machine    is an older restoration and is in excellent shape. 
This “Multi”  offers the rare combination of vintage high technology and superb riding comfort.
