Model Evolution:
The Apex series was introduced to leverage Yamaha's advanced Genesis engine. The 'LTX' designation typically signifies a longer track for better flotation and comfort in deeper snow or touring, while 'GT' denotes a more performance-oriented or standard trail model. Variations like 'RTX' (Rally/Touring Extreme) and 'RS' (Rally Sport) also existed, indicating different suspension and track configurations.
Production Period:
The first generation Apex, powered by the Genesis 4-cylinder engine, was produced from the 2006 model year through the 2010 model year. Subsequent generations evolved with updated styling and technology.
