2007 Yamaha ATTAK GT
Extreme Power Sports
Genesis 150 FI, four-stroke powered. Serious trail versatility.
- Genesis 150FI™ - 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 also delivers quick, crisp throttle response and as a bonus it runs significantly cleaner than most snowmobile engines on the market today.
- Fuel injection system - More than just a bolt-on part of the Genesis 150FI, the 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 class-leading fuel economy.
- Rear-exiting 4-2-1-2 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 for a finely balanced sled.
- 2.2 pound lighter forged crankshaft - The forged crankshaft in the Genesis 150FI is 2.2 pounds lighter than the original crankshaft design in the Genesis Extreme. This is a large contributing factor in the Attak GT's razor-sharp throttle response.
- Radiator - In order to generate consistently-strong engine performance in any condition, all Genesis 150FI sleds feature a small radiator and electric fan assembly on the right hand side of the engine cab.
- 15x136x1.25-inch Camoplast Rip Saw track - The Camoplast Rip Saw track is a standard feature on the Attak 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 is the result of a collaborative effort between Yamaha and Camoplast.
- GYTR™ piggyback reservoir dual-clicker front shocks - The GYTR™ piggyback shocks on the Attak GT's front suspension offer 12 clicks of compression AND 20 clicks of rebound adjustability for maximum tuning ability. The piggyback reservoir offers increased fade resistance to the shock.
- 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 42.7 inches. Steering is consistent, because the spindles are maintained at a constant 23 degrees.
- Integrated airbox/small hood - The design on the Attak 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 significantly smaller hood piece, which reduces weight.
- Magnesium chaincase - The Attak GT features a lightweight magnesium chaincase. The exotic material cuts a pound from the previously used aluminum chaincase on other models.
- 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.
- 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 pod. Once in suspension mode, the shock is adjusted by toggling the handgrip warmer button on the left side. While in suspension mode, the gauge will display the adjustment level, too. 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. The suspension allows 11.7 inches of vertical travel.
- Deltabox™ II with comfortable rider-forward position ergos - The primary design objective of the Deltabox II chassis was to create a comfortable rider-forward posture. The ergonomic treatment is achieved by moving the handlebars forward by 6 inches and raising them by 4 inches. The seat is also roughly 2.5 inches taller and the seated position is 8.375 inches forward of previous models. 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.
- Tall lightweight seat - The Attak GT has a tall, comfortable seat. It has been specifically built for the hard-charging rider who likes to ride aggressively. The seat features the roomy cargo space. The seating position is 6 inches forward and 2.5 inches taller than other conventional seats. The added height of the seat makes it even easier to go from sitting to standing, while the firmer foam provides extra confidence in the bumps.
- Wide, hooked handlebars - To match the tall and forward rider position, a tall, hooked handlebar is standard fare on the Attak GT. The design incorporates keyed slot hooks on both sides to eliminate unwanted hook rotation. The hooks have the same grip material as the main bar section, for more consistent control, regardless of hand position.
- Apex-style digital gauge - The Attak GT features a digital gauge cluster. 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. Owners can access the tuning function and readout by pressing the “Mode” button on the gauge pod. Once in suspension mode, the shock is adjusted by toggling the handgrip warmer button on the left side. While in suspension mode, the gauge will display the adjustment level, too. In addition to these functions, the gauge has been styled to match the aggressive lines of the Apex body work.
- Standard electric start - Yamaha's electric starter system allows consumers to fire up their Attak GT with the turn of a key. There is no pulling on a nylon cord to get this high-tech engine growling! Electric start has been a standard feature on all of Yamaha's 4-stroke machines.
