Performance


Genesis® 150FI 4-stroke engine: The Genesis 150FI engine has been a leader in the top performance category, powering happy Apex LTX GT® owners across frozen lakes, up dizzying slopes, and down sanctioned drag race strips. The super-smooth 4-cylinder design produces ultra-reliable 150 horsepower-class performance and fuel economy. The advanced fuel injection system means hassle-free starts and easy throttle pulls.


Advanced fuel injection system: The high tech, low-pressure fuel injection system uses an injector and butterfly valve throttle body on each cylinder to aid in delivering outrageously crisp throttle response, 150 horsepower production and excellent fuel economy.


Lightweight rear-exiting titanium exhaust: The exhaust pipes coming out of the Genesis 150FI engine are configured in a 4-2-1-2 design. The exhaust, featuring titanium head pipes, adds to the engine’s higher output and also reduces weight. The patented rear exit design serves many performance-enhancing functions. First, it cools the pipe by running it down the tunnel, where it can be snow-cooled. Second, it reduces the amount of under-hood heat produced. Third, the rear-exiting design distributes weight to contribute to the excellent balance of the sled.


Lightweight forged crankshaft: The forged crankshaft in the Genesis 150FI is 2.2 lbs. lighter than the original in the Genesis Extreme. This is a large contributing factor in the Apex LTX GT’s razor-sharp throttle response.


Lightweight hydraulic brake system: The lightweight 4-piston brake system delivers solid stopping power without fading, even in high-use applications. It also incorporates a lightweight, double-finned, self-cooling brake disc.


15 in. x 136 in. x 1.25 in. Camoplast® Rip Saw™ track: The Camoplast® Rip Saw™ track is a standard feature on the Apex LTX GT. It has been widely acclaimed in the industry as the best all-around OEM track for acceleration, cornering bite and everyday trail usage. The Rip Saw™ track development is the result of a collaborative effort between Yamaha and Camoplast®. Churning the track is a pair of factory-engineered extrovert drive sprockets. The engineering team purpose-built these sprockets to work with the Rip Saw™ track and reduce vibration.


Handling


Deltabox™ II with comfortable rider-forward position: The primary design objective of the Deltabox II chassis was to create a comfortable rider-forward posture. The ergonomic treatment is achieved by locating the handlebars and seated position high and forward on the chassis. With this positioning, the rider can go from sitting to standing and back again easily and comfortably. It also centralizes the combined mass of sled and driver, for razor-sharp handling.


Second generation front suspension geometry: The geometry of the second generation front suspension features short spindles and long A-arms. The suspension was engineered to deliver excellent cornering stability and consistent turning effort throughout its travel stroke. It delivers 9 inches of vertical travel and sets the skis at 42 inches. Steering is consistent, because the spindle caster is maintained at a constant 23 degrees.


Tall, wide, hooked handlebars: To match the tall and forward position, a single-piece, dual-hooked handlebar is standard fare on the Apex LTX GT. The hooks have the same grip material as the main bar section, for consistent control, regardless of hand position on the grip.


Integrated airbox/small hood: The design on the Apex LTX GT is very efficient, often integrating many functions into one component. One such example is the use of the airbox as a part of the hood design. The upper element, closest to the headlight, is comprised of the silencer cover for the airbox. This design feature allows for a very small hood piece, which keeps weight low.


Magnesium chaincase: The Apex LTX GT features a lightweight magnesium chaincase. The exotic material is a pound lighter than the previously used aluminum chaincase on other models.


Saddleless plastic skis: The saddleless plastic ski offers low unsprung weight and its aggressive keel design provides strong bite to help the Apex LTX GT corner.


Comfort


Öhlins® Mono Shock® EC 136 rear suspension: The Öhlins® Mono Shock® EC 136 rear suspension is highlighted by a push-button activated, electronically-controlled Öhlins® shock. Owners can access the tuning function and readout by pressing the “Mode” button on the gauge. Once in suspension mode, the shock is adjusted by toggling the left side handgrip warmer button and the gauge will display the adjustment level. While the Öhlins® Mono Shock® EC 136 rear suspension delivers full range compression adjustability from handlebar, the rebound is adjustable via a clicker on the shock body.


GYTR® dual-clicker front shocks: Lightweight premium GYTR dual-clicker shocks offer riders the highest level of tunability on the market with 12 clicks of compression AND 20 clicks of rebound damping. Large, glove-friendly knobs make adjustments easy. The piggyback reservoir gives the shock increased fade resistance in periods of intense use.


Wheels with removable bearings: The newly designed wheels make the ride smooth and make maintenance easy. Now when the bearings need to be replaced you don’t have to purchase a whole new wheel, just remove the old bearings and insert the new ones. The wheels also include a new spoke design and a rubber rim that make for a comfortable riding experience. This new design will be implemented on the rear large wheels as well as the internal smaller wheels.


Tall, lightweight seat: The Apex LTX GT’s lightweight seat features a roomy cargo space. The height of the trail seat makes it even easier to go from sitting to standing, while the firm foam provides extra comfort. It features a color band to match the sled’s lines and graphics.


New grip warmers: The Apex LTX GT receives new, redesigned grip warmers for 2010. These new grip warmers deliver a more concentrated heat source rather than spreading the warmth out. The result is a much warmer grip for your hand’s most comfortable riding position. In addition, an insulator has been inserted between the heating element and handlebar to retain heat longer and more efficiently.


Wide runningboards with star-punched traction: The Apex LTX GT’s wide runningboards feature star-punched traction throughout their entire length. The boards also have an outer traction roll for additional sure footing. As an added benefit, the traction holes help evacuate snow and slush from the runningboard.


Digital gauge with extensive data features: The Apex LTX GT features a digital gauge array that displays a wide variety of data. Readouts include barometric measurements, dual trip meters and a clock. The digital gauge also serves as a readout and control center for the Öhlins® Mono Shock® EC suspension. In addition to the functions, the gauge has been styled to match the aggressive lines of the body work and console area.


Standard electric start: Yamaha’s electric starter system allows consumers to fire up their Apex LTX GT with the turn of a key. There is no pulling on a nylon cord to get this high-tech engine growling! Electric start is a standard feature on all of Yamaha’s 4-stroke machines.


Dual DC outlets: The Apex LTX GT offers two styles of DC outlets. It comes with a standard automotive-style outlet for cell phones, GPS or other electronics accessories. And it also comes standard with an RCA-style plug near the left hand grip to power up heated helmet visors or other small-plug accessories.


New graphic packages: The Apex LTX GT comes in two graphic packages; Yamaha blue/white as well as Yamaha black. These awesome designs produce one of the best looking sleds on the snow.
