Honda debuted their updated new CBR600RR machine last night, one which is said to weigh signifigantly less than the curent model.

Here's the details from Honda:

The 2005 CBR600RR incorporates a host of next-generation upgrades that elevate this full-on sport mount to all-new heights.
Features & Benefits

New for 2005

• Radial-mounted front brake calipers.


• 41mm inverted front fork.


• New intake port shape and redesigned exhaust for lighter weight and increased
  mid-range power.


• New piston surface treatment for reduced friction.


• Fuel injection flow increased to match intake and exhaust system changes.


• Frame and sub-frame redesigned for lighter weight while maintaining superior
  handling characteristics.


• New bodywork more closely resembles RC211V and reduces weight.


• Redesigned top triple-clamp allows for lighter weight.


• New swingarm assembly redesigned for lighter weight.


• New two-piece shock design for improved performance and lighter weight.


• Available in Red/Black, Black/Tribal, Metallic Silver/Black and Black.

• Unit Pro-Link(r) rear suspension and swingarm design inspired by RC211V.


• Dual Stage Fuel Injection (DSFI) system features two injectors per cylinder.
  


• High-revving engine redlines at 15,000 rpm.


• RC211V-style center-up exhaust system.


• Centrally located fuel tank increases mass centralization and allows more compact frame design.


• Line Beam Headlight features three-piece reflector design.

• Liquid-cooled DOHC 16-valve 599cc four-stroke inline four-cylinder engine
  features oversquare bore and stroke of 67mm x 42.5mm.


• High-revving engine has 15,000-rpm redline (CBR(r)600F4i redlines at 14,200),
  wider powerband and more over-rev than CBR600F4i.


• Compact engine length (236mm) positions the rider forward for more precise handling.


• Iridium-tip spark plugs improve fuel combustion and performance.


• Dual Stage Fuel Injection system features two injectors per cylinder--one upper and one lower--controlled by an ECU that senses rpm and throttle opening.
  Lower injector enhances rideability while upper injector improves top-end horsepower. At lower rpm only the lower injector is working. Above 5500 rpm both injectors are activated. The system uses 40mm throttle bodies.


• Denso injectors with 12 holes per injector deliver a finely atomized fuel mixture for optimum combustion efficiency and power.


• Auto enriching system is integrated into PGM-FI module, eliminating the need for a manual choke.


• Two-stage ram-air system provides a high volume of cool air to the airbox for linear power delivery and incredible engine performance.


• Cylinder head features angled valve inset to improve airflow.


• Cylinder head features two springs per intake valve and two springs per exhaust valve for optimum high-rpm valve operation and durability.


• Direct shim-under-bucket valve actuation ensures high-rpm performance and durability and offers 16,000-mile maintenance intervals.


• Light pistons, piston pins and nutless connecting rods contribute to higher-revving engine.


• Pistons receive new moly surface treatment for reduced friction.


• Double-pivot cam-chain tensioner for cam chain durability.


• Right-side starter gears for increased lean angle.


• Lightweight aluminum oil cooler.


• Smooth-shifting close-ratio six-speed transmission is closely matched to the engine's powerband.

• Die cast aluminum frame utilizes new manufacturing methods to provide optimum rigidity while reducing weight. Frame is tuned for precise handling characteristics.


• New 41mm inverted Honda Multi-Action System(tm) (HMAS(tm)) cartridge front fork features spring preload, rebound and compression damping adjustability
  for precise action.


• Unit Pro-Link rear suspension system is patterned after RC211V GP racer.
  In this system, the upper shock mount is contained within the swingarm rather than the frame. With no top frame-mount for the shock, this unique system reduces negative suspension energy from being transmitted into the frame, allowing optimum frame rigidity and improved rideability out of corners.


• Braking system features twin four-piston radial mounted front calipers, dual 310mm front discs and a single 220mm rear disc for optimum stopping power.


• Redesigned center-up exhaust system features four-into-two-into-one design for increased performance, aerodynamics, and lighter weight.


• Handlebars located below top triple-clamp for precise handling.

• Industry-leading ergonomic design features maximum rider comfort for minimum fatigue in all riding conditions.


• Centrally mounted 4.8-gallon fuel tank is positioned low in the frame, increasing mass centralization and allowing a more compact design. This design positions the rider 70mm forward for optimum handling.


• Plastic tank shell cover protects tank and airbox.


• Line Beam Headlight features three-piece reflector design (first in the world) utilizing two H7 bulbs for optimum light distribution, and unique compact
  design.


• Instrumentation is very compact and features tachometer, speedometer and fuel gauge.


• Attractive hollow-spoke aluminum alloy wheels feature race spec 3.5 x 17-inch front and 5.5 x 17-inch rear dimensions.


• One-piece fan assembly for maximum cooling efficiency.


• Maintenance-free battery.


• Optional seat cowl.


• Compact rear cowl storage compartment for U-type locking devices (lock
  not included) under the passenger seat.


• Pivoting aerodynamic mirrors.


• Integrated ignition switch/fork lock for added security.


• Convenient push-to-cancel turn signal switch.


• Transferable one-year, unlimited mileage limited warranty; extended coverage available with a Honda Protection Plan.
