Featuring such advanced technolo-gies as the first dual-shaft balancerever used in a Super Sport motor-cycle engine for remarkably smoothoperation at all engine speeds,Honda’s innovative Dual CombinedBrake System for the ultimate inbraking confidence and control, and an attention-grabbing ‘piggy-back’-style dual headlight for thesmallest frontal area (and relateddrag coefficient) of any streetbike in its class, the Super Blackbird im-pressively redefined the standardsof ‘big-bike’ performance and sporttouring excellence.

For its next generation, the SuperBlackbird’s design team set out toimprove upon its power and potentialwith the addition of several new,yet proven technologies to carry it higher still into the upper realmsof superbike performance. With thelogical inclusion of a programmedfuel injection system, a new high-pressure Direct Air Intake systemand other high-precision enginecontrol systems, the Super Black-bird achieves a full-bodied increasein overall performance coupledwith smoother, easier operationand enhanced reliability.

These new systems also make possible the development of a new low-emissions version of the Super Blackbird to be intro-duced in Germany and Switzerlandas further proof of Honda’s uncom-promising dedication to reducingthe impact of motor vehicles on our fragile environment. All thesefactors come together in the all-newCBR1100XX Super Blackbird as it reasserts its claim to the title of‘The World’s Greatest Super Sport.’

Introduced two years ago as Honda’s flagship entry to the big-bore Super Sportclass, the CBR1100XX Super Blackbird soon took centre stage with a class-lead-ing combination of advanced high-speed aerodynamics, breathtaking power,effortless middleweight-class handling, and peerless long-term sport touring riding comfort. Developed under the guiding concept of ‘The World’s GreatestSuper Sport,’ the ‘Double-X’ soon gained a devoted following, as affirmed by itssubsequent unit sales far exceeding projected figures.

Unchanged from its introduction,the CBR1100XX’s air managementdesign takes an unprecedentedapproach to aerodynamic efficiencyand high speed potential. Ratherthan throwing more brute horse-power at the barriers to higherspeed, the XX’s design team chosethe ‘path of least resistance’ byminimizing the most significantobstacle to ultimate top speed:

wind resistance and drag. This wasachieved with a remarkably smallbullet-nosed front cowl made possibleby a revolutionary new ‘piggyback’headlight design, and a narrowfrontal aspect that reduces its coefficient of drag to levels lessthan that of a 250cc machine.

Even more remarkable is that nocorners were cut in maintaining

the CBR1100XX’s superb level of wind protection for both riderand pillion passenger. The fairing’sorganic design cuts through the air like a bullet, providing light and easy handling and a comfor-table ride at even the astoundingautobahn speeds the XX is easilycapable of achieving.

The new-generation 1999CBR1100XX Super Blackbirdfeatures three new, high-qualitycolour variations that give dynamicemphasis to its stunning, high-speedaerodynamic design and blisteringperformance. Cleanly executed withno lines and graphics except foridentifying markings, these colourvariations project a strong, purpose-ful image that draws attention tothe CBR1100XX’s muscular, perfor-mance-oriented lines. They include:

• A regal, wine-coloured candy redthat accentuates the SuperBlackbird’s curves with a luxuri-ous look of shimmering luxury.

• A deep pearlescent black that shimmers with rainbow-colouredreflections under the sun, and projects a sinister urban sophisti-cation in keeping with the CBR1100XX’s world-beating performance potential.

• A lively, eye-catching new candy blue that quickens the pulse and tickles the heart like nothing ever seen before in this class of motorcycle.

Other styling changes for the newCBR1100XX include an eerie new,multi-hued diffraction coating onthe lower half of the windscreen

that changes colour as the angle of reflected light changes. Also, new matte-finish gold-co-loured engine case covers replacethe gloss black covers featured onthe current model, gold coloured aluminium brake rotor hubs replacethe current model’s black-paintedstainless steel hubs, and chrome-plated louvers positioned deepinside the nose cowl’s new airintake ducts replace the currentlyused mesh steel inserts.

Although the Super Blackbird’s basicexternal design remains identical to the slim, highly aerodynamicspeed machine that debuted in 1997,under the distinctive bodywork of

this second generation Super Sporttouring flagship lie several majorchanges that result in a significantincrease in the CBR1100XX’s over-all performance. The first clue to

this power-packed difference can beseen in the nose ducts of the fairing,which now contribute an eye-open-ing surge in the Super Blackbird’shigh-speed power output.

While the CBR1100XX’s cavernous9.5-litre aircleaner still receives asteady stream of cool outside airfrom the two ports located on eitherside of the fairing’s upper cowl, thetwo nose ports that used to direct air only to the oil cooler are nowconnected to a pair of specially de-signed intake ducts that feed largevolumes of high-pressure air directlyinto the aircleaner for a major boostin top-end power and high-speedperformance. The only visible out-side difference is in the replacementof the screens positioned immediatelybehind the port entrances of thecurrent model by a set of vertical lou-

vres positioned deeper in the duct tokeep insects and other foreign objectsfrom entering the system while max-imizing the system’s free-breathingperformance. Specially mouldeddeep in the one-piece air ducts, the recessed positioning of theselouvres ensures a steady buildup ofair pressure inside the duct, sincethe forward-positioned screens ofthe current model would tend todeflect nearly as much air as they let pass through at high speeds.

Although the ideal shape for thesenew Direct Air Intake ducts undercontrolled conditions at full operat-

ing capacity might be somethingcloser to a straight tube, in the realworld of ever-changing variablesthe engine’s intake demands whenthe throttle is snapped opened atlower speeds would suck all the air out of the ducts before a speedcould be reached that would createenough air pressure to sufficientlyreplenish the air in the system.Therefore, the Super Blackbird’snew Direct Air Intake ducts weredesigned with uniquely shaped large-volume air cavities that ensure a steady supply of air to the enginefor quick acceleration from all speeds.

Compact, Lightweight and Powerful1,137cm3 EngineThe CBR1100XX’s high-powered,liquid-cooled DOHC inline-4 enginefeatures the same compact configu-ration and advanced, high-perfor-mance design with which it firstdebuted. Unchanged are the en-gine’s open-deck casting and side-mounted cam drive, which helprealize its ultra-narrow design,

its innovative dual-shaft balancer,which makes possible its remarkablysmooth operation and permits the engine to be rigidly mounted inthe machine’s lightweight dual-spardiamond-configuration aluminiumframe, and its high-accuracy 3D map-type digital electronic ignition system,which ensures superb responsethroughout the XX’s wide powerband.For 1999, the XX’s engine receives

the benefits of several new tech-nological developments that notonly give it a stronger surge ofpower and performance to keep it running at the top of its class,but also ensure it provides itsriders with long years of flawlessoperation, fewer annoying distrac-tions from the joys of riding and,in a sign of the times, minimizedimpact on the environment.

New PGM-FI Electronic Fuel Injection SystemLike the ’98 VFR that debuted lastyear to worldwide acclaim, this year’snew Super Blackbird now comesequipped with a high-performancecomputer-controlled PGM-FIProgrammed Fuel Injection systembased on the system originally devel-oped for Honda’s RC45 Superbikeracer. Featuring an advanced designthat integrates its Electronic ControlUnit (ECU) with the digital elec-tronic ignition in a single compact‘black box,’ this all-new systemensures ultra-precise fuel meteringfor top performance over a widerange of operating conditions andan 8% improvement in fuel consump-tion figures over the current model.Also, in combination with some

other specialized components, the system helps make possible theachievement of some of the lowestemission figures ever attained in a large-displacement motorcycle.

While large volumes of cool,power-producing air are suppliedby the large-capacity, free-breathingaircleaner, which receives an extraboost at higher speeds from thenew Direct Air Intake system, the PGM-FI system’s four 42mmthrottle bodies are fed a steady sup-ply of fuel from an electronic fuelpump built into the large, 24-litrefuel tank. The incoming fuel is thenpreheated by a line feeding off thecoolant system to ensure optimalfuel atomization and a stable air/

fuel mixture is delivered to all cyl-inders for reliably smooth, power-ful and efficient performance in allweather conditions.

Even the injector bodies’ plasticvelocity stacks have been speciallytuned for optimal performance.The two velocity stacks for cylin-ders 2 and 3 are 10mm longerthan those for cylinders 1 and 4.This difference in length helpssmooth the intake timing for eachcylinder. Likewise, the internaldiameters of the stacks narrow by approximately 1mm at theirbase in order to maximize theirventuri effect and accelerate theflow of air into the cylinders.

New Automatic Bypass StarterA quick inspection of the SuperBlackbird’s right-side handlebarcontrols finds the distinct absenceof a choke lever. However, the leverwasn’t merely repositioned, it waseliminated entirely. Partly this isdue to the incorporation of theCBR1100XX’s new fuel injectionssystem, which provides preciselythe correct volume of fuel for mostoperating and starting conditions.But mostly this is due to the incor-poration of a new Automatic By-pass Starter system that provides an extra shot of air to assist startingand warm-up when coolant tempera-tures fall below 40° C. Below thistemperature, fluid viscosity becomesthicker, internal mechanical frictionincreases, and fuel tends to condensealong the inside walls of the throttlebodies and intake ports. These fac-tors combine to create an inertial

resistance that is too great for the fuel injection system alone to overcome, thus making coldweather start-ups difficult andinitial warm-up operation roughand irregular.The bypass starter features a smallpiston built into each throttle bodywhich opens and closes an internalauxiliary air passage. When open,these air passages provide an extrashot of air into the combustion cham-bers that enhance combustion andtemporarily increase the idling speed.On the system used in the VFR intro-duced last year, this piston is manual-ly operated by way of a handlebar-mounted lever, what would be the‘choke’ lever on a conventionally carbureted machine. However, the XX’s new bypass starter systemfeatures an actuator that automati-cally adjusts the bypass starter’sposition in response to engine

temperature. Upon initial cold start-up, this actuator holds the bypassstarter piston open to optimize theflow of air into the intake ports relative to engine temperature. As the engine heats up, and the extra air is no longer required,warm coolant passing through theactuator causes an internal wax tomelt, expand, and push the pistonrod in to gradually close theauxiliary air passage. At this point,an adequate volume of air flowsthrough the throttle bodies to en-sure steady idling without requiringassistance from the bypass starter.With the addition of this automaticbypass starter system, start-ups arenow as quick and simple as the touchof the starter button, warm-upoperation is kept to a minimum,and engine operation is as smoothas can be—whatever the conditions.

New ‘Knock Sensor’Whether mechanical or electronic,an engine’s maximum spark advancefor each engine speed range is usu-ally set at a much lower degreethan would be best for optimalcombustion, particularly at higherengine speeds. This setting discrep-ancy owes to the problem of deto-nation or ‘knock’ that can occur ifthe ignition timing becomes too faradvanced. Thus, the spark advanceis generally set below the lowestlevel in the engine’s entire rev rangethat detonation is likely to occur.This setting maybe fine for elimi-nating ‘knock,’ but is not the bestfor achieving an engine’s mostefficient performance.

The Super Blackbird’s new digitalignition system now features a new‘knock sensor’ that automaticallyand precisely adjusts the sparkadvance to maintain it at the optimalsetting for all engine speeds whileminimizing the occurrence of deto-nation, or knock. Mounted to therear of the cylinder block, this knocksensor detects even the most minuteinstances of detonation and trans-mits that information to the ECU.The ECU then quickly and automat-ically retards the spark advance in intervals of 2’ until no furtherknocking is detected, then graduallyincreases the advance in muchsmaller intervals of 0.35’ to maintain

it at the optimum angle just belowwhere detonation occurs.

The addition of this system greatlyimproves engine performance,response and drivability, especiallyin the 3,000 to 6,000rpm range.However, while it is designed toprevent detonation under normaloperating conditions, the system isNOT designed to compensate forthe use of low-octane fuel nor protectthe engine from other unusual condi-tions that might induce detonation.

New Stainless Steel 4-2-1-2 Exhaust SystemThe CBR1100XX’s new stainlesssteel 4-into-2-into-1-into-2 exhaustsystem features thinner wall tubing for a 300g loss of weightcompared to the painted steelsystem it replaces. Its large 6.4-litrepolished stainless steel canister-stylesilencers were also modified withthinner-wall internal plates toachieve a 640g reduction in com-bined weight.

To give the engine a more solid boost of low-to-midrange power and stronger acceleration, the ar-rangement of the exhaust pipes was changed from the currentmodel’s 180° pairing of the pipesleading from cylinders 1 & 2 and 3 & 4 to a 360° pairing of cylinders1 & 4 and 2 & 3. While this newgrouping tends to reduce theengine’s top-end power outputsomewhat, the Super Blackbird’s

new Direct Air Intake system more than compensates for theloss with its big surge in high-speed performance.

Low-Emissions HECS-3 (Honda Evolutional Catalyzing System)Demonstrating Honda’s concernfor the environment and dedicationto minimizing the motorcycle’s con-tribution to air pollution, Honda haschosen to incorporate its highlyeffective HECS-3 catalyzer systeminto the German and Swiss versionsof the CBR1100XX to reduce its

emissions output to unprecedentedlevels for its class. First introducedlast year on the new VFR, the system’slow emissions figures are madepossible by the incorporation of theengine’s new fuel injection and airinjection systems and the furtheraddition of an exhaust pipe-mountedoxygen sensor and a pair of compactcylindrical catalyzers built into the

silencers’ inlet tubes. Remarkably,the system’s resulting emissionsfigures are below even those tentati-vely proposed for Europe’s futureEURO-2 emissions regulations,while its fuel consumption figuresare fully 15% lower than for thecurrent model.

Air Injection SystemNow featured on several Hondamodels in the interests of reducedexhaust emissions, and included onall versions of the ’99 CBR1100XX,this new, relatively simple systemdirects a precisely timed jet of freshair from a small airbox mountedatop the engine’s cylinder head cover down to each cylinder’s ex-haust port, just behind the exhaustvalve. This shot of extra oxygen tothe hot, pressurized gases rushingout of the combustion chamberhelps prolong the burning of theexhaust’s residual fuel and pollutantsinto the port. The result is morecomplete and efficient combustion,

and a reduction in carbon mono-xide (CO) and hydrocarbon (HC)emissions that ensures completecompliance with Europe’s currentEURO-1 emissions regulations.

‘O2’ Exhaust SensorLike the system featured on last year’sVFR, the ECU of the CBR1100XX’snew PGM-FI system continuallymonitors several critical variables ofengine operation in order to ensureprecise fuel control. For the low-emis-sions version of the XX, the ECUalso monitors the digital output of a single oxygen sensor mounted inthe exhaust system just before thejunction leading to the two silencers.

This oxygen sensor constantly mea-sures the fluctuating oxygen levels inthe engine’s exhaust gases, allowingthe CPU to instantly calculate com-bustion efficiency and adjust the in-take’s air/fuel mixture accordingly. In order to maintain a precise balanceof hydrocarbons (HC) and carbonmonoxide (CO) emissions on onehand and nitrous oxides (NOx) emissions on the other, this ‘O2 feedback’ system maintains the air/fuel ratio within a pre-designated tolerance range centred on an opti-mal ratio of 14.7 : 1 that permits the catalyzers to perform at theirhighest efficiency under mostoperating conditions.

‘3-Way’ CatalyzerThe final components in theCBR1100XX’s low-emissionssystem are the cylindrical catalyzerunits installed in the exhaustsystem immediately before each of the canister-type silencer bodies.These compact ‘3-way’ catalyticconverter elements complete thesystem’s high-efficiency operationby chemically minimizing the emis-sions of CO, HC and NOx gasses.

New Transmission Friction DamperIn an effort to minimize the annoy-ing ‘clunk’ of metal against metalthat often occurs when motorcyclesare shifted into gear from neutral at stop, particularly in cold condi-tions, the CBR1100XX’s engineersdeveloped a simple yet effective newdamping system that softens the jolt.Mounted on the transmission’s mainshaft, this hard rubber ‘friction’damper quickly slows the spinningmain shaft when the clutch is pulledin to reduce the difference in speedbetween it and the stopped coun-tershaft, thus reducing the shock tothe gears on the two shafts as theymate, and significantly reducingthe resulting ‘clunk.’

New, Lighter-Action ClutchAlthough the CBR1100XX’s hydrau-lic clutch action was never especiallyheavy, efforts were still made to makeit as light and easy-to-use as possible.This lighter action was achieved witha change in the clutch ratio and im-provements to the master cylinderthat combine to reduce clutch leverpressure by approximately 15%. The use of a newly developed clutchfriction plate material and strongersprings also permitted a reduction in the number of plates from nine toseven while maintaining the same dia-meter and rugged capacity to matchto the engine’s enormous power.

Maximized Cooling EfficiencyThe new CBR1100XX’s coolingcapacity was also improved withthe addition of a new, larger-volumealuminium radiator. Positionedlower in the fairing to make roomfor the new Direct Air Intake system,this new radiator features a thinnercore (reduced from 32 to 24mm)but a broader surface area that im-proves cooling efficiency.

The radiator also features a newfan that draws air more efficientlyto ensure optimum cooling whenstopped or stuck in traffic. Instead

of rotating within a circular frame,as in a conventional design, the bladesof the fan are now joined to the outerring, which now also rotates closeto the rear surface of the radiator.This new design concentrates the fan’ssuction effect through the radiator,rather than also drawing air ineffec-tively in from around the blades,thus maximizing its suction power.

The CBR1100XX’s oil cooler wasalso moved down from its currentposition in front of the steering headto make room for the new DirectAir Intake system. Now mounted

directly to the upper edge of theradiator, where it catches a steadycurrent of air entering the fairingfrom above the front wheel, the newoil cooler was also made wider fora significant increase in volume thatcombines with the new positioningto ensure greatly increased coolingcapacity over a wider range ofriding conditions.

New Anti-Theft Ignition SecurityAs concerns about motorcycle theftcontinue to grow, Honda has madeconcerted efforts to help its customersprotect their investments. From intro-ducing convenient carrying spacesfor carrying strong ‘U’-locks andchains to providing handy and effec-tive lock-down points in a motorcy-cle’s frame and bodywork to securethem, Honda motorcycles help theirowners fight back against theft.

Being introduced this year for thefirst time ever on Honda’s newest,most popular motorcycles—andnotably on the Super Blackbird—is an innovative new anti-theft ignition system that prevents theengine from being started by anyother than the motorcycle’s twooriginal keys.

This new anti-theft system featuresa special coded chip implanted ineach of the keys supplied with themotorcycle and a coil antenna builtinto the ring surrounding the upperedge of the key switch that instantlydetects the presence of an encodedkey. This code is then transmittedto the ignition and fuel injectionsystem’s ECU (electronic control unit)and compared against the two codenumbers (one for each key) that theECU is programmed to recognize.

If the code is correct, as indicatedby the new LED positioned in thelower right quadrant of the tacho-meter, the engine can be startednormally. However, if the keycode doesn’t match the ECU’scode, even if the key is identical

in every other way, the ignitionremains switched off and the en-gine cannot be started. Likewise,since the engine is disabled at theignition’s ‘black box,’ it cannot bebypassed by either hot-wiring theignition or exchanging the combi-nation switch module. The systemalso features a more robustly con-structed combination switch thatmore effectively resists tampering.

While the Super Blackbird’s newanti-theft ignition system cannotprotect the motorcycle against everypossibility of theft, it does effecti-vely prevent the motorcycle frombeing ridden away, thus preventingone of the most common forms oftheft, and hopefully convincingpotential thieves and joyriders tolook elsewhere.

Larger, New 24-Litre Fuel TankThe addition of the CBR1100XX’snew fuel injection system also allowedthe aircleaner to be repositioned several centimeters farther forwardwhile maintaining its current volume.This repositioning provided an extraspace into which the underside of thefuel tank could be expanded, resultingin an additional two litres of fuel capacity, and subsequently a sig-nificantly extended touring range.

The tank incorporates an electricfuel pump to ensure a steady supplyof fuel to the injectors, while the low-emissions version of the SuperBlackbird features a narrower, ‘lead-free-type’ inlet that prevents leadedfuel from accidentally being added,which could seriously damage theexhaust system’s built-in catalyzers.(This special inlet reduces capacity to 23 litres.)

Weight-Saving ComponentryTo keep the CBR1100XX’s weightto a minimum, even with the addi-tion of its new fuel injection andDirect Air Intake systems, no com-ponents were overlooked in thequest of lighter weight. The CBR’saluminium footpegs were reduced in size for a savings of 100 grams,handlebar castings were redesigned,realizing another 80 grams weightreduction, and even the brake

lever was trimmed, although for a slightly different, somewhatamusing reason.

It seems that at the nearly 300km/h autobahn speeds theSuper Blackbird is capable ofreaching, the wind pressure on the current brake lever’s frontalsurface area was strong enoughto engage the brake light switch.

So, to minimize the chance of thisodd, unexpected effect, the brakelever’s frontal aspect was slimmedand rounded to make it more ‘ae-rodynamic’ and thus less likely tobe moved by the wind. Strange, but true, and all in the interests of making EVERY detail of theCBR1100XX Super Blackbird the best it can possibly be.
