The CBR is kind of mythical in the Supersport world. Radicalised years after years the 2008 version is now the meanest of all. With its technical features directly took from competition bikes, like the Honda Electronic Steering Damper handed down from Honda’s famed RC211V (MotoGP bike), or the centralisation of the fuel tank.
Of course featured with radial mounted front brake calipers, the new CBR 1000RR Fireblade 2008 is also smaller, sharper, lighter and more powerfull with its new engine. The 2008 CBR 1000RR is also featured with a new slipper clutch...
New Features
New Styling Features
- New lighter, more compact and curvaceous bodywork design places stronger emphasis on high-performance function over form (No comment).
- New rear-view mirrors with integrated indicator lights.
- New, more compact and aggressively stylish instrument panel design.
- New ram air ports integrated into front cowl replace central intake above radiator for more efficient induction of cooler air at front of machine.
- Smaller, lighter and more compact seat and tail cowl take design cues from the RC212V MotoGP racer, made possible by new underslungmass-centralised exhaust system.
- Manual, toolbox & small HACE U-lock fit in compact locking tail cowl storage space.
- Tail light/licence holder integrated into slim, one-piece resin moulding hanging under tail cowl.
New Performance Features
Engine
- New 2.5kg lighter, more compact engine features 1mm bigger bore and 1.4mm shorter stroke for stronger power delivery.
- Redline extended from 12,250min-1 to 13,000min-1.
- New separate cylinder block with lighter new sleeveless JCP (Jet-flow Circulation Plating) cylinders replaces current integrated cylinder/upper crankcase and ceramic composite sleeves.
- Lighter new titanium intake valves with dual concentric valve springs for precise actuation at high revs.
- Lighter, higher-strength forged pistons with 1mm larger bore and same weight for higher, faster revving capability.
- Newly developed Assist Slipper clutch achieves smoother, less abrupt engine-braking downshifts and quicker, more efficient re-acceleration.
- Cable-actuated clutch provides lighter, more comfortable action and more responsive feel.
- New taller and narrower radiator enhances engine cooling efficiency while reducing fairing width.
- Compact, new underslung exhaust system improves mass centralisation while optimising cornering clearance for sharper, more responsive handling.
- Electronically controlled intake and exhaust valves for reduced intake noise and enhanced performance.
- Lower exhaust noise and emissions achieved while still reducing weight.
Chassis
- Overall weight greatly reduced relative to both current model and competition, for the strongest power-to-weight ratio in the litre-displacement Super Sports class.
- New chassis design further improves mass centralisation.
- New 4-piece cast aluminium frame achieves lighter weight while being fully 30mm narrower.
- New frame construction reduces width while significantly increasing rigidity (lateral +13%; torsional +40%; vertical +30%).
- New shorter and more compact cast aluminium seat rail.
- New, lighter-weight hybrid extruded/pressed aluminium swingarm features new gull-wing design and 15mm longer effective length while maintaining essentially same wheelbase.
- Swingarm-integrated Unit-Pro-Link rear suspension system with fully adjustable HMAS damper essentially unchanged from current model.
- Front fork span reduced by 10mm (from 214mm to 204mm) for quicker response to turning inputs. Front fork offset increased by 2.5mm (from 25 to 27.5mm) for optimised balance of handling performance. Front axle holders feature new, more centred design that increases rigidity while maintaining light weight.
- New hollow-section triple-spoke wheels feature thinner spoke castings for reduced weight (F: -240g; R: -370g).
- New, 101g lighter RK X-ring drive chain.
- New front disc brake callipers feature one-piece monoblock construction for lighter weight and increased rigidity. New chrome-plated aluminium pistons replace steel units for lighter weight and enhanced durability. Unsprung weight reduced by a total of 430g.
- New brake rotors feature 6-point floating mounts, compared to current 10-point configuration, for lighter weight. Variable rotor hole sizes improve braking feel while reducing weight.
- Front brake lever ratio modified slightly for enhanced braking response. New front brake hoses also of lighter construction.
- New, smaller and lighter second-generation steering damper adapted from CBR600RR. Mounts behind steering head rather than above it.
- New, more compact 7AH battery is over 1kg lighter than conventional 10AH batteries. Modified starter ratio and revised starter motor characteristics ensure torque and starting capacity maintained with less current draw.
- New aluminium sidestand.
