The suspension system closely resembles the Vickers type. There are 18.4 cm wide tracks with 131 small links and three bogies per side, sprung by small leaf springs, carry each two small road wheels. The prototype had an armoured plate protecting this assembly but it was omitted on the production vehicles to save weight, leaving only two elongated beams to brace the whole. Likewise the sprocket was simplified: the prototype's had been a closed disk, the production type had six circular holes; later vehicles were fitted with a wheel with six spokes. There are two return rollers. In all the suspension system is flimsy and vulnerable. This is compensated by limiting the official maximum speed to thirty kilometres per hour, although the combination of a weight of just 2.64 metric tons with an engine power of 38 hp would allow for a higher speed; during testing 36 km/h was attainable. This also reduces the chance of accidents while towing the trailer; fully loaded the road speed is reduced to 25 km/h, the cross-country speed to ten km/h. The wading capacity is thirty centimetres; the trench crossing capacity 120 centimetres. The turning circle is three metres; a slope of 50% can be climbed.
