If tough and durable machinery is the order of the day, then the 2005 Eiger series of QuadRunners are Suzuki's special. Named after the well-known Swiss peak, Suzuki Eigers are tough machines that set the standard for ATV performance and value. For 2005, the entire line of Eiger QuadRunners are decked out with a new bold, aggressive look. They're powered by a proven 376cc four-stroke engine and get support from a strong, sturdy frame. Their suspension is set up to handle any kind of terrain. Introducing the 2005 Suzuki Eiger, in two hard working versions:

  • The LT-A400F Eiger Automatic 4X4, featuring an automatic CVT transmission with high/low range and reverse, and a limited-slip front differential.
  • The LT-F400F Eiger 4X4, featuring a five-speed-plus-reverse manual transmission with high/low range and automatic clutch and a limited-slip front differential.

Both Eiger models feature a dependable 376cc single-cylinder, four-stroke, air/oil-cooled SOHC four-valve engine, with 9.0:1 compression ratio, a single 32mm Keihin carburetor, a gear-driven balancer to reduce vibration, and a wet-sump lubrication system. Power is transmitted through your choice of a fully automatic transmission with V-belt and continuously variable gear ratio, or a manual five-speed with reverse transmission with centrifugal automatic clutch and two-speed sub-transmission. The automatic model utilizes an advanced braking mechanism and two-speed sub-transmission with a reverse gear. In addition, four-wheel-drive power is transferred through Suzuki's unique torque-sensing limited-slip front differential and an easy-to-use handlebar-mounted 2WD/4WD-control lever.

The Eiger frames are created with large-diameter, thin-walled tubing for maximum strength and minimum weight. Aggressive bodywork, high-radius fenders, a rugged styled grill and large front bumper provide a bold and sporty look. The front suspension uses an independent double A-arm design with a class-leading 6.7 inches of travel. A dual-shock swingarm rear suspension offers 6.7 inches of travel and 9.8 inches of ground clearance. Braking duties are handled by dual 190mm front disc brakes combined with a water resistant drum mounted at the rear. Other features include a start-in-gear system for quick and easy restarts, spin-on oil filter, standard brake light, large four-gallon fuel tank with fuel gauge, large-sized tires and wheels, high-capacity cargo racks, full floor boards, and a high-strength skid plate that won't dent or rust and provides a slick surface that won't catch on rocks or trees. Named after a mountain, built to take on life's mountains: The 2005 Suzuki Eiger Series of QuadRunners.
