An all-terrain vehicle including a frame having longitudinally-spaced ends defining a first longitudinal axis, and an engine supported by the frame. The engine includes a crankshaft defining a second longitudinal axis substantially parallel to the first longitudinal axis.

Drivetrain for an all terrain vehicle

Frame for an all terrain vehicle

This invention relates to multiple driven axle vehicles, and particularly to all-terrain vehicles equipped for rear wheel drive, four wheel drive, and on-demand front wheel drive. The invention is directed toward a system of switchable traction options allowing the vehicle operator to easily choose between different modes, such as rear wheel drive with an open or unlocked differential, rear wheel drive with a locked differential, four wheel drive with open differentials, four wheel drive with one locked differential, four wheel drive with two locked differentials, or rear wheel drive with on-demand four wheel drive.

Multimodal vehicle traction system

An engine is disclosed which may operate in a first operating state wherein a spark ignited fuel is ignited in a combustion chamber with an igniter and a second operating state wherein a compression ignited fuel is ignited in a combustion chamber with an igniter. A compression ratio in the combustion chamber being up to about eight to one. The engine may be a four-stroke engine. The engine may include a piston having a top portion with a recessed central portion.

Method and operation of an engine

A front storage box for use on an all-terrain vehicle. The front storage box comprises two components: an accessory box and a cargo rack. The accessory box forms a storage compartment in which cargo may be stowed. The cargo rack is integral with a lid for the accessory box and functions to both seal the accessory box and act as a rack. Thus, items may be placed in the accessory box and on the rack for hauling.
