2016 Yamaha Apex® X-TX 1.25''

Let's do the math. Genesis Top Performance engine plus 144" Camoplast Ripsaw track equals maximum power to the snow. The highly refined Apex X-TX is back but also comes with a 1.75 track option for better off-trail capability when the ride calls for it. All traditional Apex amenities like power steering and tuner skis are standard, and Yamaha's 'Single Shot' and Fox FLOAT 3 XV rear suspension allow for better customization and weight saving.

• 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 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 rear frame was designed to accommodate the shortened muffler to further enhance mass centralization.

• TUNED FOR MORE TOP-END PERFORMANCE

The Apex engine received many modifications to improve power output and control, including a air-box with modified intake funnels, revised intake cam timing, and 38mmm 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° 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 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.

• 146" RIPSAW II TRACK

The Apex X-TX features a fully clipped 15" x 146 x 1.25" track with extrovert drivers for incredible ratchet-free traction and acceleration.
