Suzuki GSX-R1000

Sports motorcycle

The Suzuki GSX R1000 (often called a Gixxer) is a supersport motorcycle made by Suzuki. when measured on the rear wheel with small variations between different instances of the same model. The redline is set at 12,000 rpm. The maximum torque of the engine is at 8,000 rpm. Combined with a total (dry) weight of this gives the GSX R1000 a top speed of ,

The 2001 model carried over to 2002 with minimal changes. 2002 introduced i. a. modifications to the fuel pump, clutch, front axle, torque link, mirrors, and luggage hooks. The manual fast idle was replaced with a computer operated implementation (the "STV servo"). New colors, and new GSXR stickers.

After the GSX R1000 had been three years on the roads and race tracks, Suzuki put out a new version of the model in late September 2002. Suzuki engineers had been working on the three things that made a fast bike faster; weight, power, and handling. The 2003 year's GSX R1000 was improved in all three counts. It weighed less, had more power/torque, and handled better. The physical dimensions of the bike were almost identical to the previous year's model. The seat height and the overall height were somewhat lower but the geometry of the bike was exactly the same as before. The already rigid aluminum alloy frame was newly designed and enforced with internal ribs, also there was an updated headlight and tail fairing. The frame, as well as the wheels, were now coated black. The front brakes were also new. Suzuki decided to drop the six piston calipers. The new radially mounted four piston calipers weigh 30 grams less and grip smaller discs that save another Though smaller, Suzuki claimed that the new brakes provide better stopping and turn in performance. The headlights of the 2003 year's GSX R1000 were mounted vertically to enable the ram air intakes in the front to be placed nearer the bike's centerline. The new design was very much inspired by the look of the Hayabusa. The instruments were also redesigned. The cylinder displacement of the engine remained the same , but more power/torque and better throttle response had been achieved by adding four ventilation holes between the cylinders to equalize crankcase pressure beneath the pistons, moving the air intake nearer to the centerline and upgrading the engine management system from a 16 bit to a 32 bit ECU. The entire exhaust system was now made of titanium to save an additional and the tail light was replaced with LEDs. The 2003 model carried over to 2004 without any significant improvements.

The 2005 model year GSX R1000 had a redesigned engine and chassis. It had lower weight than the previous model and the engine had an larger displacement due to a 0.4mm bore increase. It had a totally new frame reducing the total length of the bike by but reducing its wheelbase only There were new brakes with radial mounted calipers and discs at the front. The new titanium silencer (catalytic in Europe) was said to be designed to reduce turbulence to minimum. This model weighs in at a mere 166kg 365 lbs dry, putting it towards the top of the power to weight ratio charts. The 2005 model has a tested wet weight of Power output is tested at and peak torque is both at the rear wheel. This model is the first to get the addition of traction control with a (IMU) inertial measuring unit measuring yaw, roll and pitch also all lighting is now LED. Another first for any GSX R is the use of a fuel gauge on this model. Along with the new 2017 GSX R1000 model, Suzuki has also released an up spec model GSX R1000R; this R model comes with a Motion Track Brake System, Bi directional quick shifter and launch control. Also on the R model, as reported by Sport Rider, are the same Showa Balance Free Front (BFF) fork and Balance Free Rear Cushion (BFRC Lite) shock that come standard on the 2016 Kawasaki ZX 10R. Specifications are 202 horsepower at 13,200 rpm (claimed), 177.2 (rear wheel), 86 lb ft torque at 10,000 rpm (claimed) and (rear wheel); 76.0 mm x 55.1 mm bore x stroke, and 13.2:1 compression ratio. It will be illegal to register the model in the EU, EFTA, or UK from 1 January 2023 unless it is updated to comply with Euro 5. New sales are already banned in India as it does not comply with BS VI.

Troy Corser won the 2005 Superbike World Championship season, and Alessandro Polita won the 2006 FIM Superstock 1000 Cup season. The bike was used by Yukio Kagayama and Kousuke Akiyoshi to win the Suzuka 8 Hours endurance race in 2007, with Kazuki Tokudome and Nobuatsu Aoki doing the same in 2009. Michael Dunlop rode the GSXR at the 2022 Isle of Man TT Senior.
