A ground clearance of not more than 600 mm beneath the lowest points of the front- and rear-axle housings (not considering lower points on the axle differential).
A fixed or adjustable minimum track width of one of the two axles of less than 1 150 mm when fitted with the widest specified tyres.
A mass greater than 600 kg but less than 3 000 kg, unladen, including the ROPS and tyres of the largest size recommended by the manufacturer.
