Electric Power Steering
 Yamaha's EPS system is high-tech and super lightweight, requiring no fluids or heavy pumps. It is a dynamic system that monitors vehicle speed, engine rpm and the rider's steering input to calculate the optimum amount of steering assistance more at low speeds and less at high speeds. EPS accomplishes a few things. Primarily it decreases steering effort making the machine feel lighter. But EPS also helps limit negative feedback coming through the skis. And since steering effort can be more easily controlled, different ski and runner combinations can be used with little impact on steering effort. The right combination of EPS, suspension geometry, ski and runner, allow the new Apex to carve through turns with incredible precision and minimal effort.  
EXUP Delivers Smooth Torque Characteristics
 Yamaha's EXUP System utilizes a titanium body and butterfly valves that prevent the "blow back" phenomenon caused by valve overlap. This design reduces weight and eliminates "flat spots" in the power band while reducing emissions at the same time.  
Aluminum Frame
 Yamaha's lightweight CF die cast aluminum frame provides exceptional rigidity and balance. The new rear frame was designed to accommodate the shortened muffler to further enhance mass centralization.  
Tuned for More Top-End Performance
 The new Apex engine received many modifications to improve power output and control, including a new air-box with modified intake funnels, revised intake cam timing, and new 38 mm 4-into-1 titanium exhaust with EXUP. These changes do increase peak power, but also dramatically improve throttle response and low-to-midrange torque.  
Tuner Skis
 The addition of Yamaha's acclaimed Tuner Dual Keel skis greatly reduce darting and offer a wide range of carbide set-up options, from mild to aggressive pattern.  
Revised Intake Valve Timing
 We changed the lift angle of the intake valves from 104 to 109 degrees increasing the overlap of the intake / exhaust valves which when combined with EXUP results in more power and a smoother power delivery.  
Lightweight Pistons and Oil Rings
 Lightweight forged aluminum pistons with a new dome shape for uniform combustion are very strong, yet lightweight, and reduce vibration while running quieter.  
ISC (Idle Speed Control)
 ISC ensures stable idle right after starting. Not only does it improve starting and idling stability, it also controls changes in idling speed to facilitate warm-up, with improved starting and idling performance at higher altitudes. ISC also incorporates EBRS (Engine Braking Reduction System).  
 Addition of a knock sensor adjusts the ignition timing to prevent irregular combustion. If lower octane fuel is used the ignition timing will automatically compensate by retarding the ignition timing to prevent knocking, to ensure consistent and reliable engine performance.  
Intake Funnels & Intake Tract
 The shape and length of air funnels, along with the air cleaner have been designed to work in conjunction with EXUP for superior performance.  
38 mm Titanium 4-into-1 Exhaust Pipes for More Perf
 New 38 mm titanium exhaust pipes form a 4-into-1 unit, tuned for improved power development at higher rpm. Larger diameter tubing combined with EXUP improves the efficiency of pressure waves from each cylinder that resonate inside the exhaust pipes, thereby improving performance in the medium and high rpm ranges. The new design uses shorter diffuser and moves the muffler further forward contributing to better mass centralization.  
 The Apex X-TX incorporates a Dual Shock CK rear suspension with tipped up rails and independent forward and aft shock absorbers for improved ride comfort and versatility. Dial in compression damping with the remote clicker to adjust the ride to suit your style.  
144-inch Rip Saw® Track
 The Apex X-TX features a fully clipped 144 x 15 x 1.25-inch track with extrovert drivers for incredible ratchet-free traction and acceleration. With tipped up rails this versatile package is able to adapt to a variety of riding environments. Thanks to EPS the 8HV ski, it can out handle the old 136 while bridging bumps like a 144. Perfectly happy playing off trail now and again, the longer track X-TX will really shine when you stretch its legs on those long distance runs.  
Two DC Outlets
 Charge your cell phone, plug in your GPS, or other electronic accessories to the standard automotive-style outlet. There's also an RCA-style plug near the left hand grip to power heated helmet visors or other small-plug accessories.  
Improved Wind Protection
 A lot of effort was spent improving ride comfort including wind protection. There's a new three-piece windshield, completely redesigned for more wind protection without compromising top speed performance. The side panels were also modified to improve airflow around the rider, extending the air envelope especially around the riders legs.
