Suzuki Protection Plan is a comprehensive plan that covers all mechanical, electrical and computer systems on your Suzuki Motorcycle or ATV. Ask your local Authorized Dealer about Suzuki Protection Plan for extra peace of mind.

The new and exclusive Suzuki Racing Variable Valve Timing System (SR-VVT) uses a centrifugal actuated mechanism on the intake camshaft sprocket to increase high engine RPM power without losing low-to mid-range power.

The new design Suzuki Racing Finger Follower valve train weighs less than a tappet-style valve train for reduced friction and increased valve response at higher engine speeds. Titanium valves, two 31.5mm intake and two 24mm exhaust valves, are used for each cylinder. The lighter valves respond well to the finger follower’s arms and permit a 14,500 RPM redline that helps produce very high peak horsepower.

Aluminum pistons, 76.0 mm in diameter, were engineered with use of FEM (Finite Element Method) analysis, and are forged for optimal rigidity and weight.

The automatic Idle Speed Control (ISC) improves cold starting and stabilizes the engine idle regardless of engine temperature.

Complementing the four primary fuel injectors in the throttle bodies are four Suzuki Top Feed Injectors (S-TFI) that spray fuel from the top of the air box directly into the intake funnels. This results in higher peak power, more efficient combustion, and a higher level of fueling control.

To increase top end power without losing lower RPM performance, the air box is equipped with Staked Air Intake Funnels for the #1 and #4 cylinders. This simple design allows good air flow at all intake speeds without requiring a mechanism that adds weight or complexity.

The 4-2-1 thin wall Suzuki Advanced Exhaust System (S-AES) is designed to help the engine deliver a wide range of performance with an exciting rush up to redline. The muffler has a pleasing appearance while creating an exciting, distinctive sound.

New design SET-Alpha exhaust valves are in the balance tubes between the #1 and #4, and the #2 and #3 head pipes. Actuated by a cable from the main SET-valve, the Alpha valves open at higher engine speeds and close at lower RPM to help the engine create high peak power without losing low and mid-range horsepower.

The cooling system was designed using advanced analysis design so the coolant flows through the engine and radiator more efficiently. This design uses 400cc less coolant than the prior GSX-R1000, but the new system has better cooling efficiency while being more compact and lighter. The fairing lowers efficiently guide cooling air to the high-capacity curved radiator. Twin cooling fans ensure good cooling at lower road speeds. Additional heat is removed from the engine via the use of an air-cooled, radiator-style oil cooler mounted directly below the main radiator.

Based on Suzuki’s race-proven six-speed close-ratio transmissions, the new GSX-R1000 features vertically staggered shafts to reduce overall engine length. The primary gear ratio is lower compared to the prior GSX-R1000 for stronger acceleration. A programmable shift light is on the main panel to provide a visual alert to the rider to shift when a certain engine RPM is reached. To reduce weight, a new 525-size drive chain is used with a 45/17 final sprocket ratio that complement the larger, rear tire dimensions.

Using lessons learned from Suzuki MotoGP chassis development, the engine angle of the GSX-R1000 was rotated backwards 6-degrees. This had the joint effect of reducing the distance of the fork to the center of the chassis by 20mm and increase the swingarm length by 40mm. This increased chassis stability and improves aerodynamics.

The new, aluminum twin-spar style frame was designed using FEM analysis technology to place strength is the proper places, the new frame is also 10% lighter than the prior generation GSX-R1000. The spars of the frame are set 20mm closer to help improve aerodynamics, looks and to bring more comfort to the rider.

All-new Aluminum Superbike-braced Swingarm has equalized bracing to the main beams to provide balanced support and movement to the shock absorber to improve racetrack handling while conveying a consistent suspension feel to the rider. Racetrack-developed links connect the single SHOWA Remote Reservoir Shock Absorber to the braced swingarm. With spring preload, rebound damping, plus high and low-speed compression damping force adjustment the rider can tune the motorcycle to respond to riding style and weight.

The new BREMBO T-drive Brake Rotors feature two methods of attaching the 320mm floating disc to the carrier. There are five conventional floating rotor spools that maintain the rotor’s relationship to the caliper and five new-design T-drive fasteners. This combed attachment technique allows the rotor to absorb more energy so more braking force is available to a GSX-R1000 rider than ever before. BREMBO Radial Mount Brake Calipers provide the rider with strong braking performance combined with superb feel. The front brakes are complemented by a 240mm rear disc brake with a NISSIN single-piston caliper to help make sure you can have controlled stops.

NEW Aerodynamic Bodywork was created by Suzuki styling designers and engineers using numerous wind tunnel tests to achieve a slippery shape and compelling appearance. Narrower than ever before, the GSX-R1000’s shape directly aids performance by improved handling and top speed on the racetrack. The reasonable sport riding position is created by a carefully crafted relationship between the clip-ons, footrests and seat. The top of the fuel tank is lowered 21mm to make it easier for the rider to tuck in on a racetrack straightaway.

The new LCD Multi-function Instrument Panel was inspired by the GSX-RR MotoGP dash. This panel is laid out so the rider can easily see the tachometer bar, speedometer digits, and other essential operational information. This effective display is critical as it is the rider’s interface to the GSX-R1000’s advanced electronics.

The new LED headlight is lightweight, bright and distinctive. This low-electric draw light has a narrow, stacked shape to allow the SRAD ducts at the nose of the fair access to the high pressure air created at higher speeds.

LED Combination Tail & Brake Light has a very low electrical draw and the vertically stacked shape permits the tail section to be narrow for better air flow at the back of the motorcycle. License plate is also illuminated by an LED light. The Turn Signals are lightweight and use incandescent bulbs with amber lenses so the motorcycle’s turn indication is highly visible to other traffic.
