1. A power pack for a vehicle selected from a group of different vehicles, comprising:
an internal combustion engine comprising:
a crankcase;
a crankshaft disposed in the crankcase; and
a cylinder body connected to the crankcase;
a continuously variable transmission (CVT) operatively connected to the engine, the CVT comprising:
a drive pulley operatively connected to the crankshaft of the engine, the drive pulley being rotatable about a drive pulley axis;
a driven pulley rotatable about a driven pulley axis;
a belt connecting the drive pulley to the driven pulley; and
a housing at least partly enclosing the drive pulley, the driven pulley and the belt; and
a sub-transmission selected from a group of different sub-transmissions depending on the selected vehicle of the group of different vehicles, the selected sub-transmission being mounted to the housing of the CVT, the housing of the CVT being configured to mount any sub-transmission of the group of different sub-transmissions,
the group of different sub-transmissions comprising:
a first sub-transmission comprising:
an input shaft configured to be operatively connected to the driven pulley of the CVT;
a plurality of gears; and
an output shaft operatively connected to the input shaft via the plurality of gears, the output shaft being rotatable about an output shaft axis extending laterally, each of a first end portion and a second end portion of the output shaft being configured to be operatively connected to a respective ground-engaging member of the selected vehicle;
a second sub-transmission comprising:
an input shaft configured to be operatively connected to the driven pulley of the CVT;
a plurality of gears; and
an output sprocket operatively connected to the input shaft via the plurality of gears, the output sprocket being configured to be operatively connected to a ground-engaging member of the selected vehicle for driving thereof;
and
a third sub-transmission comprising:
an input shaft configured to be operatively connected to the driven pulley of the CVT;
a plurality of gears; and
first and second output members operatively connected to one another and driven by the input shaft via the plurality of gears, the first and second output members being disposed on opposite sides of the third sub-transmission, the first and second output members being rotatable about respective axes extending generally longitudinally.
