A tiltable vehicle (100) is described comprising a vehicle frame (102, 108), one front wheel (124), two rear wheels (112A, 112B) and two swing arms. The swing arms are pivotably coupled to a pivot point (121) on the vehicle frame at a first end, and to one of the rear wheels at an opposing end. A swing arm (41) is rotatable around a rotational axis (42) lying in a plane of symmetry of the vehicle frame (102, 108). Each of two linkages (63, 64) is coupled at a first end to one of the swing arms at the pivot point. The vehicle comprises two connection arms (53, 56) arranged between the linkages (63, 64) and one outer end of the rocker arm (40). The connection arms comprise resilient members (61, 62) comprising a number of Belleville springs arranged in at least two groups of rings so as to create a non-linear spring characteristic.
