Suzuki GSX-R1000
The Suzuki GSX-R1000 is a sports motorcycle made by Suzuki. It was introduced in 2001 to replace the GSX-R1100, and is powered by a liquid-cooled inline four-cylinder, four-stroke engine, although originally from 2001 to 2004.
History
2001 (K1, K2)
For 2001, Suzuki introduced a new GSX-R model that replaced the largest and most powerful model of the GSX-R series sportbike, the GSX-R1100, with the all-new GSX-R1000. As the model name revealed, the engine's cylinder displacement was roughly 100 cc smaller than its predecessor. The GSX-R1000 was not just an enlarged version of the GSX-R750, although it shared many features with the smaller version. The mainframe is the same in both models, but the material used on the GSX-R1000 was thicker. Suzuki claimed the torsional rigidity of the frame had increased 10% in comparison with the GSX-R750.The GSX-R1000 engine was a redesigned GSX-R750 engine. The GSX-R1000 had a bigger bore and longer stroke, newly designed pistons with a lower crown, and a gear-driven counter balancer. The engine weighed, which was slightly heavier than the 750 engine, but lighter than the engine of the GSX1300R. The performance of the engine is a peak of at 9,500 rpm, as measured on the crank and, 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 weight of, this gives the GSX-R1000 a top speed of, a quarter-mile time of 10.1 seconds at, and a 0 to time of 3 seconds.
Using titanium for the exhaust downpipe and the inside of the silencer, enabled the GSX-R1000s exhaust system to become lighter than that of the 750. Titanium was also used in the front fork to coat the stanchions. An exhaust-tuning valve had been mounted inside the exhaust pipe. Using a servo, the system dynamically adjusted the exhaust backpressure, according to engine speed, throttle position, and gear selection for increased torque, lower emissions, and decreased noise—the exhaust noise of the GSX-R1000 is notably lower than that of the GSX-R600.
With the 2001 model of the GSX-R1000, the 1998 Yamaha YZF-R1 was finally surpassed, with the GSX-R being lighter and more powerful.
The 2001 model carried over to 2002 with minimal changes; 2002 introduced 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. New colors and new GSXR stickers were used.
2003 (K3, K4)
After the GSX-R1000 had been on the roads and race tracks for three years, 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 model year's GSX-R1000 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, with an updated headlight and tail fairing. The frame and 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 engine control unit. The entire exhaust system was now made of titanium to save an additional and the taillight bulb was replaced with LEDs.
The 2003 model carried over to 2004 without any significant improvements.
2005 (K5, K6)
The 2005 model-year GSX-R1000 had a redesigned engine and chassis. It had a decrease in weight compared to the previous model and the engine had an larger displacement due to a 0.4 mm bore increase. It had a totally new frame, reducing the total length of the bike by, but reducing its wheelbase only. New brakes with radial mounted calipers and discs were used at the front. The new titanium silencer was said to be designed to reduce turbulence to a minimum. This model weighs 166 kg or 365 lb 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.
Also in 2005, Suzuki used a single "S" logo on the tank on all models instead of the brand's full name.
The 2005 model carried over to 2006 without any significant improvements other than a few appearance changes. The 2006 model had a measured top speed of.
On the list of fastest production motorcycles by acceleration, a 2006 GSX-R1000 at a drag strip once recorded a 0 to 60 mph time of 2.35 seconds. This is the only GSX-R1000 that has won a World Superbike championship.
2007 (K7, K8)
On September 22, 2006, Suzuki revealed a significantly updated GSX-R1000 for 2007 at the Paris Motor Show. The new bike gained over the 2006 model, due to its new exhaust system and new emissions regulations. To counter this weight increase, Suzuki claimed improved aerodynamics along with a faster-revving engine and larger throttle body. Although not a completely new model, the engine and chassis have been updated. It also featured three different engine mapping configurations, selectable using two buttons located on the right handlebar. One up, and one down arrow to cycle between Mode A, Mode B, and Mode C. It also received a hydraulic clutch.The 2007 model carried over to 2008 without any significant improvements.
2017 (L7)
The 2017 model, introduced to reporters at EICMA in late 2016, had a significantly redesigned engine, the first since the update on the 2009 model. This new engine has a higher rotational speed limit and no balancer shaft to quell vibration, and a mechanical variable valve timing used for 10 years by Suzuki in MotoGP and drive-by-wire throttle. This model was the first to get the addition of traction control with an 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-specification model GSX-R1000R, which comes with a motion track brake system, bidirectional quick shifter, and launch control. Also on the R model, as reported by Sport Rider, are the same Showa balance-free front fork and balance-free rear cushion shock that come standard on the 2016 Kawasaki ZX-10R. Specifications are 202 horsepower at 13,200 rpm, 177.2, 86 lb-ft torque at 10,000 rpm and ; 76.0 mm x 55.1 mm bore x stroke, and 13.2:1 compression ratio.Registering the model in the EU, EFTA, or UK was to be illegal 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.
