Improved chassis
The new aluminum chassis, dubbed Deltabox 3, is die cast and torsionally stiffer than the old D2. It better supports the suspension components up front and allows greater control over uneven terrain. In addition, the rear section has been redesigned to accommodate the new muffler and enhance mass centralization, and it has shed a few kilos in the process to boot.

The Deltabox 3’s side rails now have ridges that increase overall stiffness, while the top part of the chassis, wider and taller, accommodates the new steering column and its EPS. The Apex X-TX rockets along on the incredible, versatile and super grippy 1.25-inch Ripsaw tread.

Power steering
The 2011 Apex boasts revised skis that are adapted to the new electric power steering system. Thanks to their more aggressive runner and straighter, shorter keel, the skis reduce resistance on compacted snow and, consequently, swaying when entering corners.

The new EPS system allowed engineers to optimize the design of the front track without worrying about increasing steering effort. The system introduces new sensations to our sport, as the Apex proves unusually precise and easy to ride. What’s more, it still provides excellent feedback to the rider while requiring less effort and is thus better suited to long-distance excursions.

Considering the new geometry and power steering, we were expecting the considerable girth of the Apex to be less troublesome when entering corners. Although we did see some improvement, the sled still tends to understeer. On the other hand, the almost nonexistent sway increases confidence when slowing down, both for you and the riders crossing your path.

Revolutionary, proven rails
The Apex X-TX, Yamaha’s high-performance hybrid sled, rests on a Dual Shock CK 144 suspension derived from the Nytro X-TX and improved for 2011. The rails are tipped up on a 6-degree angle and ensure optimal flotation in deep snow while allowing for more aggressive and precise manoeuvres on the trail.
