CBR600RR8

Motorcycle Details

Charged The CBR 600's most radical redesign since the introduction of the RR in 2003 is highlighted by a whole new engine, frame and bodywork that results in a smaller, lighter, more-powerful CBR600RR with a class-leading power-to-weight ratio and unparalleled performance. A new lighter weight stainless steel four-into-one exhaust features new inline-exhaust valve to control exhaust pressure for maximum performance. A new intake-air control valve (IACV) minimizes torque reaction and smoothes response to small throttle changes through gradual reductions of air and fuel intake when the throttle is opened and closed.

Engine/Drivetrain

• New lightweight, forged-aluminum pistons incorporate special shot peening for added toughness.
• New, single exhaust valve-springs.
• Lightweight magnesium head cover.
• New transmission gear ratios.
• Smaller, lighter clutch.
• Liquid-cooled DOHC 16-valve 599cc four-stroke inline four-cylinder engine features oversquare bore and stroke of 67mm x 42.5mm.
• Intake port surface treatment revised for improved efficiency.
• Oil jet relocated beneath piston for additional friction reduction and cooling.
• Iridium-tip spark plugs improve fuel combustion and performance.
• DSFI system features 40mm throttle bodies and two injectors per cylinder--one upper and one lower--controlled by an electronic control system (ECU) that senses rpm and throttle opening. Lower injector enhances rideability while upper injector improves top-end horsepower.
• Denso 12 hole injectors deliver finely atomized fuel mixture for optimum combustion efficiency and power.
• Auto enrichment system is integrated into programmed fuel injection (PGM-FI) module, eliminating the need for a manual choke.
• Two-stage ram-air system provides high volume of cool air to the airbox for linear power delivery and incredible engine performance.
• Cylinder head features angled valve insets to improve airflow.
• Cylinder head features two springs per intake valve and one spring per exhaust valve for optimum high-rpm valve operation and durability.
• Direct shim-under-bucket valve actuation ensures high-rpm performance and durability with 16,000-mile maintenance intervals.
• Lighter pistons and lighter, nutless connecting rods contribute to quicker acceleration.
• Double-pivot tensioner for cam-chain durability.
• Right-side starter gears allow increased lean angle.
• Smooth-shifting close-ratio six-speed transmission with new gear ratios is closely matched to the engine’s powerband.

Chassis/Suspension

• 41mm inverted HMAS 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 two-piece shock 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.
• New vertical-piston master-cylinder system produces superior leverage ratio at the front brake lever for higher braking efficiency with excellent feel and controllability. This layout permits the use of a longer brake lever, which means more braking force with less effort from the rider.
• Lighter aluminum steering stem.
• New front-brake vertical-piston master-cylinder system.
