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 is renown for its ability to provide big horsepower in a very usable manner. This has been achieved by using a refined mixture of cam timing, air intake and a 38mm 4-into-1 titanium exhaust with EXUP. The result is an engine that has excellent throttle response, is strong from low to mid-range, and sings on top. Exactly where you want it to. |
|
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. |
|
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 perf |
| 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 design uses shorter diffuser and moves the muffler further forward contributing to better mass centralization. |
|
SINGLESHOT 146 REAR SUSPENSION |
| Yamaha's new SingleShot Rear suspension system is 10lbs lighter than the previous Apex rear. Fox FLOAT 3 XV Shock allows for not only lighter weight, but easy tuning and customization. |
|
1.75" BACKCOUNTRY TRACK |
| The Apex X-TX 1.75" uses the Camoplast Backcountry track with arched lug design and staggered pattern for excellent soft snow traction. |
|
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 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. |
