The Specifications for a Suzuki GSX-R750 K4

The 25-year history of the legendary Suzuki GSX-R750 series is filled with awards and racing trophies from across the globe. When Suzuki released the GSX-R750 K4 in 2004, the tradition of product and performance excellence continued, prompting Sport Rider Magazine to call it "more than just a motorcycle" and "an awesome combination of handling, performance, and style."

Size and Weight

The GSX-R750 K4 motorcycle measures 81.7 inches in length, 28.1 inches in width, and 45.1 inches in height, creating a wheelbase of 55 inches and a ground clearance of 5 inches. Suzuki engineered the GSX-R750 K4 to reduce the motorcycle's weight to a relatively light 359.5 pounds without fuel, offering a six-pound weight reduction from the 2003 model.

Equipped with a 16 titanium-valve, liquid-cooling, four-cylinder, four-stroke engine, the GSX-R750 K4 reaches a peak of 127 horsepower at 12,750 rpm, and a peak of 58 lb-ft of torque at 10,750 rpm. The redesigned engine in the GSX-R750 K4 features a smaller combustion chamber, an increased compression ratio of 12.3:1 and lighter valve spring rates, boosting its power output while reducing exhaust emissions.

The power of the GSX-R750 K4's improved engine is harnessed by a six-speed, rear-wheel chain-driven transmission that does not offer a reverse gear. To help bring this speedy motorcycle to a halt, the GSX-R750 K4 is equipped with 11.8-inch dual hydraulic disc brakes on the front wheel and an 8.7-inch single hydraulic disc brake on the rear wheel.

The GSX-R750 K4 features a 1.7-inch inverted fork front suspension system. Inverted fork systems reduce unsprung weight -- weight from the wheels, tires and brakes that is not supported by the suspension -- improving the motorcycle's handling. The rear suspension is composed of a single aluminum twin-sided swing arm, further reducing the unsprung weight of the system. The front and rear suspension systems feature adjustable pre-load, the ability to raise or lower the position of the suspension without the weight of the rider pushing it down. Additionally, the front and rear suspension systems feature adjustable rebound damping, allowing the rider to adjust how long it takes the suspension to rebound to its original position after being compressed or extended. The GSX-R750 K4 is a highly-customizable motorcycle, offering the rider maximum flexibility in a variety of riding situations.

The streamlined, lightweight aluminum frame of the GSX-R750 K4 is covered by shape-defining plastic body material and a two-piece vinyl seat with room for a driver and passenger. This non-adjustable seat sits at a height of 32.5 inches. The standard exterior accessories rubber hand grips, fork guards and steel foot pegs for both driver and passenger. According to Sport Rider Magazine, the GSX-R750 K4's "aggressive and distinctive" redesigned exterior is accentuated by narrow, vertically stacked halogen headlights and a shorter, narrower fuel tank that improves aerodynamics and rider mobility.

In addition to the range of performance-enhancing features on the GSX-R750 K4, the award-winning motorcycle has several standard operational features. The K4 is equipped with standard windshield mounts, digital instrumentation, shift lights and LED temperature warning and fuel-level warning lights. The K4 also is equipped with a lockable storage space beneath the seat and a standard kickstand, allowing riders to safely and easily park the motorcycle.
