Honda CBR1000RR ABS

The CBR1000RR with Combined Anti-Lock Braking, the most advanced (and first-ever) ABS system to find its way onto an open-class superbike.
The CBR1000RR is the lightest, most compact, and best performing motorcycle in its class, making it the standard against which all other literbikes are measured. And for 2009, it's available with Honda's high-tech electronically controlled Combined ABS for the ultimate in sport bike braking performance.

The Unique Features

• Dual Stage Fuel Injection System (PGM-DSFI) features two injectors per cylinder (see Technology Section).
• Idle-Air Control Valve (IACV) and Ignition Interrupt Control for idle stability and smoother on/off throttle response.
• Low-mount exhaust system design.
• Patented slipper clutch features cam mechanism to reduce clutch-lever pull.
• MotoGP-derived Honda Electronic Steering Damper (HESD) (see Technology Section).
• 43mm Honda Multi-Action System (HMAS) inverted front fork (see Technology Section).
• Exclusive, MotoGP-derived Unit Pro-Link® Rear Suspension (see Technology Section).
• Radial-mount front brake calipers combined with radial-actuated master cylinder.
• Centrally located fuel tank increases mass centralization for a more compact frame design.

The Engine/Drivetrain

• Compact, liquid-cooled DOHC 16-valve 999cc four-stroke inline four-cylinder engine features bore and stroke dimensions of 76mm x 55.1mm.
• Removable cylinder block with Nikasil-coated cylinders.
• Sixteen-valve cylinder head features 30.5mm intake and 24mm exhaust valves with a 12.3:1 compression ratio for efficient combustion and high horsepower.
• Larger titanium intake valves create a lighter valve train and feature double-spring design for optimum performance at high rpm.
• Intake ports use latest shot-peening technology that improves power and torque characteristics.
• Cam-pulser location between the middle cylinders allows a narrower cylinder head and frame.
• Direct shim-under-bucket valve actuation system ensures high-rpm durability and allows 16,000-mile valve maintenance intervals.
• Forged-aluminum thin-domed, high-strength pistons feature molybdenum coating for reduced friction.
• Lightweight nutless connecting rods.
• Iridium-tip spark plugs improve fuel combustion and performance.
• Dual Stage Fuel Injection (DSFI) (see Technology Section).
• 46mm throttle bodies feature Denso injectors with lightweight valving for faster reaction time and 12 holes per injector to optimize mixture atomization, combustion efficiency and power.
• Auto-enriching system is integrated into Programmed Fuel Injection (PGM-FI) module, eliminating the need for a manual choke.
• Idle 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.
• Ignition Interrupt Control system works with IACV and FI mapping to enhance driveability.
• Smaller and lighter ECU provides two 3-D fuel-injection maps for each cylinder and two 3-D ignition maps for cylinder pairs, creating ideal fuel mixture and spark-advance settings for superb rideability.
• MotoGP-derived twin-tunnel ram-air system allows a high volume of cooler air to the 9.7-liter airbox for linear power delivery and incredible engine performance.
• Butterfly valves inside the ram-air ducts open and close depending on throttle opening and engine rpm for optimum performance.
• Compact, low-mount exhaust system design reduces rear bodywork size and incorporates exhaust valve and catalyst, contributing to significantly improved mass centralization, and reducing roll and yaw inertia.
• High-capacity radiator incorporates twin cooling fans and allows a more compact cowl for reduced drag coefficient.
• Maintenance-free automatic cam-chain tensioner.
• Starter gears located on the right side to produce narrow engine that allows for increased lean angle.
• Patented slipper-clutch design uses a center cam-assist mechanism for easier actuation. Unlike an ordinary slipper clutch where the pressure plate moves from side to side, the Honda clutch moves both the center cam assist and the pressure plate to provide additional slipper effect.
• Nine-plate clutch is compact and tough, featuring durable friction plate material.
• Durable #530 O-ring-sealed drive chain.

The Chassis/Suspension

• Lightweight four-piece Fine Die-Cast twin-spar aluminum frame utilizes latest MotoGP technology (see Technology Section).
• Aluminum subframe is lightweight and easily removed for ease of maintenance.
• MotoGP-derived, next-generation Honda Electronic Steering Damper (HESD) (see Technology Section).
• 43mm inverted aluminum-slider Honda Multi-Action System (HMAS) cartridge front fork features spring preload, rebound and compression damping adjustability, and offers precise action and unparalleled rigidity (see Technology Section).
• Exclusive, MotoGP-derived Unit Pro-Link Rear Suspension (see Technology Section).
• Radial-mounted monoblock four-piston front calipers feature chromium-plated aluminum pistons and squeeze lightweight 320mm floating discs in front and a 220mm rear disc with a single-piston caliper for exceptional stopping power.
• CBR1000RR ABS features Honda's electronic Combined ABS. This all-new ECU-controlled, hydraulically actuated system provides accurate braking force distribution to both wheels. ABS is controlled by a hydroelectronic unit and stroke simulator to ensure precise operation. Benefits include consistent lever pressure without the pulsing often associated with ABS systems. Application of rear brake does not result in immediate front brake activation unless lock-up is sensed, allowing an experienced rider to use rear brake in a normal manner during spirited riding. Combined ABS components are smaller and lighter than conventional hydraulic ABS designs, and have been located nearer to the center of the machine, enhancing mass centralization and reducing unsprung weight.
• Super-light aluminum-alloy hollow-spoke wheels feature race-spec 3.5 x 17-inch front and 6.0 x 17-inch rear dimensions.
• Centrally mounted 4.7-gallon fuel tank is positioned low in the frame, increasing mass centralization and allowing a more compact design. This design positions the rider farther forward for optimum handling.
