Yamaha’s Apex clan comes in three versions. The engine package remains the same, while the suspensions differ.

The corporate descriptions of each version indicate the target rider of each machine. The RTX is positioned as “rough trail performance,” the GT as “groomed trail/rough trail crossover,” and the ER as “groomed trail performance.”

Styling reflects these different attitudes. The RTX has a shorter windshield with exposed, tall, hooked handlebars with handguards. The GT has a mid-sized windshield with the tall, hooked handlebars, as does the ER.

All Apex machines have a restyled snowflap for 2007. They come set in the Deltabox II chassis, which promotes a rider-forward position. The seats are tall, though they are most firm on the RTX model. The ER has blue-tinted headlights and yellow-tinted on the RTX. They also use a 15- by 121- by 1.25-inch Camoplast Rip Saw track.

Trunk space has expanded on the RTX model. Electric start is standard on all Apex models, but reverse is only standard on the GT and ER versions.
