A multi-track vehicle having a lean drive and locking system which is primarily activated when the direction of the vehicle is changed by steering so as to provide increased stability, rideability and efficiency of operation. The leanable multi-track vehicle has a main chassis for carrying an operator which is supported on at least three wheels which are spaced from each other, at least a pair of the wheels are located transversely to each other with respect to said main chassis. A subframe supports the pair of wheels from the main chassis such that the main chassis may lean with respect to the said subframe and the pair of wheels. A drive system is provided for leaning the main chassis with respect to the subframe, and a locking device is provided which locks the position of the main chassis with respect to the frame or prevents the main chassis from leaning in one direction or the other with respect to the subframe.

[ What is claimed:] [1.] A leanable multi-track vehicle having a main chassis for supporting an operator which main chassis is supported on at least three wheels which are spaced from each other, at least a pair of said wheels being located transversely to each other with respect to said main chassis, a subframe for supporting said pair of wheels from said main chassis such that said main chassis may lean with respect to said subframe permitting said pair of wheels to follow the terrain in the roll axis, while not transmitting roll input to the main chassis, a locking means having first and second portions, said first portion of said locking means being secured to said main chassis and said second portion of said locking means being secured to said subframe, for locking said main chassis and said subframe and pair of wheels in a predetermined position with respect to each other, control means for actuating said locking means to first and second half lock conditions, when in said first half lock condition said main chassis is prevented from leaning in a first direction, and when in said second half lock condition said main chassis is prevented from leaning in a second direction opposite said first direction with respect to said subframe, whereby said main chassis may be leaned with respect to said subframe and pair of wheels and locked in said leaned position while said vehicle is in motion or at rest.
