Frame and Steering Geometry

• The 2005 GSX-R1000K5, as it is designated by Suzuki, utilizes an all-new aluminum alloy twin-spar frame that shortens the total length of the motorcycle while reducing its wheelbase by less than a half of millimeter. Rider comfort was drastically improved by the frame's smaller dimensions, providing a shorter reach to the handlebars and a lower seat height. The rear swing arm was also redesigned for optimum rigidity to provide exceptional rider control and feedback. The new GSX-R's dry weight of 365 pounds, combined with a steep steering head angle of 23.8 degrees and 3.8 inches of trail, allows for stable yet agile handling. The new frame is wrapped in a redesigned fairing that incorporates the front and rear turn signals into the the rear view mirrors and the tail cowling, reducing aerodynamic drag by up to 5 percent.
  
  

Suspension

• The 2005 GSX-R1000s is supplied with a pair of 43 mm inverted telescopic forks, featuring fully-adjustable preload, rebound and compression damping. To improve the fork's responsiveness to changing road conditions, the lower fork tubes are coated with Suzuki's diamond-like compound (DLC), reducing friction and providing additional protection from scratches. A non-adjustable steering damper was also fitted to the lower fork clamp to aid high-speed stability. A single rear shock absorber also features fully adjustable preload, rebound and compression settings connected by linkage to the rear swingarm.
  
  

Wheels and Brakes

• The 2005 GSX-R1000 is equipped with a pair of 17-inch cast aluminum wheels. The wheels were redesigned with thinner spokes to reduce unsprung weight and aid maneuverability. These spokes, though physically thinner, are constructed with a thicker inner wall to maintain structural rigidity. The wheels were fitted with a 120/70ZR17 radial tire on the front wheel and a wider 190/50ZR17 radial tire on the rear wheel, both made by Bridgestone. Hydraulic disc brakes are equipped on the front and rear wheel. A pair of 310 mm steel rotors mounted on the front wheel are gripped by radially-mounted four-piston calipers, improving stopping power and rider feedback. The rear wheel is equipped with a single 220 mm steel rotor and is actuated by a two-piston rear caliper.
  
  

Motor and Transmission

• Numerous revisions and upgrades were performed on the new for 2005 motor, aimed at improving the motor's power delivery. The GSX-R's already powerful liquid-cooled four-stroke motor received an increase in cylinder bore and stroke, enlarging from 73 x 59 mm to 73.4 x 59 mm, increasing the motor's displacement from 988 cc to 999 cc. Power output was increased by utilizing smaller combustion chambers in new cylinder heads, featuring larger 30 mm intake and 24 mm exhaust ports. These changes increased the motor's compression ratio from 12.0:1 to 12.5:1. Further revisions included titanium valves, lighter forged pistons and a reinforced crankshaft with chrome-molybdenum connecting rods to increase and extend operation at higher engine speeds. The newly-acquired power was transmitted to the ground via a 6-speed, wet sump transmission, incorporating a new back-torque limiting slipper clutch to reduce the engine braking effect at high engine speeds. Final drive is provided by a 17-tooth engine sprocket and a 42-tooth rear wheel sprocket turning a 110-link, 530-pitch O-ring-type chain.
  
  

Electrical and Fuel Systems

• Power is supplied by a 12-volt, 10-amp hour battery and is recharged through a revised compact stator/alternator. An electronic control unit (ECU) controls several of the GSX-R1000's onboard exhaust tuning and emissions systems. Fuel is supplied to the motor through electronic fuel injection, featuring two injectors per throttle body to compensate for increasing fuel demands based on throttle position and engine speeds.
