suzuky gsx- R1000

For 2001 Suzuki introduced a new GSX-R model that replaced the largest and most powerful model of the GSX-R series sport bike, the GSX-R1100, with the all new GSX-R1000. As the model name revealed, the engine's cylinder displacement was 100 cc (6.1 cu in) smaller than its predecessor. The GSX-R1000 was not just an enlarged version of the GSX-R750, although it shared many features with its little brother. The main frame is the same in both models, but the material used on the big brother was .5 mm (0.020 in) thicker. Suzuki claimed the torsional rigidity of the frame had increased 10% in comparison with the GSX-R750. The dimensions of the bike had more in common with the GP racer Suzuki RGV500 than the GSX-R750.

The GSX-R1000 engine was a redesigned GSX-R750 engine. The R1000 had a 1 mm (0.039 in) bigger bore and 13 mm (0.51 in) longer stroke, newly designed pistons with lower crown, and gear-driven counter balancer. The engine weighs 130 lb (59 kg) which was slightly heavier than the 750 engine but 31 lb (14 kg) lighter than the engine of the GSX1300R. The performance of the engine is a peak of 160 bhp (120 kW) at 9,500 rpm^[1] as measured on the crank and 143 hp (107 kW)^[2] 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 80 ft·lbf (110 N·m) at 8,000 rpm. Combined with a total (dry) weight of 374 lb (170 kg) this gives the GSX-R1000 a top speed of 192 mph (309 km/h), a 1/4 mile time of 9.3 seconds at 157 mph (253 km/h), and a 0 to 100 km/h (62 mph) time in 3 seconds.

Using titanium for the exhaust pipe and the inside of the silencer, the R1000's exhaust system had become 4 pounds lighter compared with the 750. Titanium was also used in the front fork. The inner tubes were coated with the resistant material. A unique exhaust tuning valve had been mounted inside the exhaust pipe. Using a servo the system dynamically adjusted the exhaust back pressure, according to engine speed, throttle position, and gear selection for increased torque, lower emissions, and decreased noise -- the (stock) exhaust noise of the GSX-R1000 is notably lower than that of the GSX-R600.

With the 2001 model of the GSX-R 1000 the 1998 Yamaha YZF-R1 was finally surpassed with the GSX-R being lighter and more powerful. ^[3]

The 2001 model carried over to 2002 with minimal changes. 2002 introduced i.a. modifications to the fuel pump and luggage hooks. The manual fast-idle was replaced with a computer operated implementation (the "STV servo"). The color options were changed to replace the pearl black and metallic silver with a candy blue and pearl black scheme.
