     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 about eight additional horsepower over its forebear, the Genesis Extreme™, to hit 150hp-class performance. It also weighs 7 pounds less than the Genesis Extreme. The engine’s high-tech fuel injection system delivers quick, crisp throttle response and as a bonus it runs significantly cleaner than most snowmobile engines on the market today.
    • Advanced fuel injection system
      More than just a bolt-on part of the Genesis 150FI, the advanced fuel injection system required a full engine redesign. The low-pressure system uses an injector and butterfly valve throttle body to aid in delivering outrageously crisp throttle response, 150 horsepower production and excel-lent 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 pounds lighter than the original in the Genesis Extreme. This is a large contributing factor in the Apex MTX’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.
    • 16x162x2.25-inch Camoplast® Maverick™ track/extrovert drive sprockets
      Yamaha and Camoplast® collaborated in the design of the Maverick™ track. The 16x162x2.25-inch track features a 3-inch pitch to allow more snow to pack in between the lugs for a firmer grip on the snow. Also, the lugs are extremely varied in design and profile for even more traction in multiple snow conditions. Churning the track is a pair of factory-engineered extrovert drive sprockets. The engineering team purpose-built these sprockets to work with the Maverick™ 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 further centralizes the combined mass of sled and driver, for razor-sharp handling.
    • Tapered mountain tunnel
      To accommodate the 16-inch wide track, the Apex MTX has a mountain-specific tunnel that is lighter than previous mountain tunnels. It features a straight angle for simplicity and rapid snow evacuation. In addition, the runningboards are wide with aggressive star-punched traction along their length. Overall, the tunnel is 140mm longer than previous mountain tunnels.
    • Adjustable-width second generation front geometry
      The second generation geometry on the front end of the Apex MTX uses the same short spindles and long A-arms as the trail Apex machines, but adds an adjustable width feature to allow owners to set the skis at the desired width. In addition, the configuration maintains spindle castor at 23 degrees throughout the travel stroke. This gives the sled consistent and predictable steering regardless of the suspension’s activity.
    • Tall, wide, hooked mountain handlebars
      To match the tall and forward position, a single-piece, dual-hooked handlebar is standard fare on the Apex MTX. The hooks have the same grip material as the main bar section, for consistent control, regardless of hand position on the grip. Mountain riders will appreciate the center grab strap when it’s time for sidehilling.
    • Integrated airbox/small hood
      The design on the Apex MTX 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 MTX features a lightweight magnesium chaincase. The exotic material is a pound lighter than the previously used aluminum chaincase on other models.
     Comfort
    • ProMountain™ 162 rear suspension
      The lightweight ProMountain rear suspension is a conventional torsion spring design. It was engineered to help the sled get up on plane in the fresh snow. It does this through weight transfer and shallow track approach angle. The dual-angle rails also give the Apex MTX excellent trail man-ners, while maintaining its deep snow flotation. The ProMountain 162 delivers 14 inches of vertical travel. The rear idler wheel is elevated 25mm, thanks to the dual-angle rail design.
    • KYB® gas cell shocks
      The KYB® gas cell shocks on the Apex MTX’s double wishbone front suspension geometry deliver consistent performance with good fade resistance. They give the sled its nice, plush ride quality.
    • Mountain-style rear rack
      The Apex MTX uses a new, lightweight rear rack design. Mountain riders will be able to cinch down their extra gear, using the aluminum anchor points on the tunnel. The new design eliminates the weight of the former composite rack while affording owners the opportunity to pack their things on the sled.
    • Wide runningboards with star-punched traction
      The Apex MTX’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 confi-dence and comfort.
    • Digital gauge with extensive data features
      The Apex MTX 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 and reverse
      Yamaha’s electric starter system allows consumers to fire up their Apex MTX 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. The Apex MTX comes standard with reverse to help consumers get their sled off the trailer.
