The Trail Sled With Industry-Dominating 4-Stroke Power.


150 HP Class.


Performance:


Genesis 150FI™ 4-stroke engine - The Genesis 150FI 4-cylinder engine is designed to build high horsepower and keep weight low. It cranks out 150hp-class performance. The engine’s high-tech fuel injection system delivers quick, crisp throttle response and as a bonus it runs significantly cleaner than many snowmobile engines on the market today.


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 high output and also keeps weight low. 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 for a finely balanced sled.


Lightweight forged crankshaft - The forged crankshaft in the Genesis 150FI is 2.2 pounds lighter than the original in the Genesis Extreme. This is a large contributing factor in the Apex ER’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.


15x121x1.25-inch Camoplast® Rip Saw™ track - The Camoplast Rip Saw track is a standard feature on the Apex ER. 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.


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 further 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 ER. 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 ER 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 ER features a lightweight magnesium chaincase. The exotic material is a pound lighter than the previously used aluminum chaincase on other models.


Comfort:


Mono Shock™ RA rear suspension - The Mono Shock RA rear suspension uses a single shock to control the travel of the skid. The shock is remotely adjustable via a rotating dial located conveniently on the left side of the tunnel, near the driver’s leg. The suspension is widely adjustable to suit nearly any rider in nearly any condition. In addition to the remote adjustment, the Mono Shock RA is also adjustable at the coil spring and at the control rod.


40mm aluminum HPG front shocks - The 40mm High Pressure Gas (HPG) shocks on the Apex ER’s second generation front suspension geometry deliver consistent performance with excellent fade resistance.


Tall lightweight seat - The Apex ER’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.


Wide runningboards with star-punched traction - The Apex ER’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, delivering additional confidence and comfort.


Digital gauge with extensive data features - The Apex ER features a digital gauge array that displays a wide variety of data. Readouts include barometric measurements, dual trip meters and a clock. 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 ER 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
