2007 Yamaha Attak GT
- 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.
