2014 Yamaha Apex


O'Brien's Sale & Service Ltd.



A true game changer, the first snowmobile equipped with Electric Power Steering.

For the snowmobiler that demands all day long top performance trail riding, the Yamaha Apex goes above and beyond expectations.

Featuring the 4-cylinder Genesis 4-stroke engine, industry-first Electric Power Steering (EPS) and Yamaha's unique EXUP exhaust system. The 150HP-class Genesis 150FI engine delivers mind-bending performance. When you let off the throttle, the EBRS helps you coast smoothly to a stop, rather than decelerating under engine braking. The radical Yamaha EPS system is the first ever found on a snowmobile and delivers easy, precise steering, enabling you to ride harder, faster, and longer while minimizing fatigue. An entirely adjustable suspension aboard the Apex provides a comfortable, personalized ride. The Apex is packed with Yamaha advantages for top mileage performance.

  • Electronic 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 assist… 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 38mm 4-into-1 titanium exhaust with EXUP. These changes do increase peak power, but also dramatically improve throttle response and low-to-midrange torque.
  • Revised Intake Valve Timing: We changed the lift angle of the intake valves from 104° to 109° 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).
  • Knock-Sensor: 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.
  • 38mm Titanium 4-Into-1 Exhaust Pipes for More Performance: New 38mm 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.
  • 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.
  • Apex 128" Monoshock RA 2 Rear Suspension: Yamaha's Monoshock suspension is already known to be one of THE best rear suspensions in the business for trail riding. The new 128" Monoshock RA II is the next step in ride comfort and control, providing improved anti-bottoming, a smoother ride and excellent straight line stability. The RA variation retains the Remote Adjust clicker in the side of the tunnel for easy adjustment to suit varied trail conditions and your riding style. The new 128 inch Ripsaw track is fully clipped and features extrovert drivers to eliminate ratcheting.
  • 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.
  • Exceptional Wind Protection: With the redesign of the Apex in 2011, a lot of effort was spent improving ride comfort including wind protection. The three-piece windshield was designed to provide excellent wind protection without compromising top speed performance. The side panels are designed to improve airflow around the rider, extending the air envelope especially around the riders legs.
