2004 HONDA FIREBLADE
Test by Jeff, pics by Pete

For me there hasn’t been one disappointing Fireblade. All of them have been cutting edge motorcycles.

All of them have had brilliant road and track manners and, more importantly, all of them have had that trademark Honda feel of complete control.

 


But as I set up for turn one at Eastern Creek with the ‘Blades digital speedo flickering up around280km/h it’s very clear to me that this is the fastest CBR ever. Believe me. The ‘Blade is back with the big guns in the top end stakes. Or at least it’s closer than ever before.

I’ve just jumped off WG’s ‘Blade, which is very firm for a stocker, so my press bike feels plush as I apex turn one with a wiggle here and a wallow there. What was near perfect over the 1000-odd-km I’ve done this week on the road is now too soft and sloppy.

Back in the pits we set the bike up to Wayne’s specs – one notch from hardest on preload, a bit more comp and standard rebound. The front isn’t too bad so we leave it.

I head back out and feel like I’m on rails from the word go. Turn two flips from a boring, uneventful, yawn of a corner to a ‘slam and turn’ kink that I hardly notice. And there is no vague feeling normally associated with a steering damper in such a slow corner. This H.E.S.D thing really works!

Flicking the CBR from full lean to full lean through turns four and five is easy, quick and accurate thanks to the extra ride height. The ‘Blade feels agile and willing and I’m 100% more confident as a result. Despite its pleasant manners the CBR is proving to be an animal and a half in the excitement stakes. But it is still so easy to ride. I just don’t know how Honda have pulled this one off.

I put my head down for a few laps. WG comes past me on an R1 in turn 12 and I spend so much time thinking about the massive, smoking black line he just laid that I turn in late for turn one! Trail braking deeper than ever I haul the ‘Blade back on line but it’s too late to try and get a tow. Wayne’s long gone. No pointers for me today.

Hard on the brakes into turn two the ‘Blade is very stable and the feel on offer from the new Tokicos is intimate though not quite class leading. Stopping power is very good. There is reasonable edge-grip feel from the front Pilot Sport but nothing to write home about when compared to the newer Pilot Powers.

But the feel at the lever still allows for hard braking on the side of the tyre and I’m getting more confident in the front into corners now.
Off the brakes, running into fast corners with the throttle shut (like turn four) I’m a little unsure about grip but as soon as the throttle is cracked the bike just drives forward and feels planted. It goes wherever I want it to. I think the Unit Pro-Link set up has something to do with it because, in this situation, the CBR feels different to any other bike I’ve ridden (I’ve only done a few laps on the 2004 CBR600RR, which has the same linkage). Turn four is really bumpy but I feel detached from the back end through there. It is hard to explain but it feels similar to when you ride over a series of bumps on the gas but weight the pegs so your butt is off the seat. The bike is just moving around beneath you.
On the ‘Blade you are positioned normally and it still feels like that. Make sense?

Flicking the bike from right to left on the brakes into turn six and seven is easy, highlighting the agility of the bike – agility that wasn’t really on offer on stock settings. And the lack of headshake as I button off briefly before tipping into turn eight (the bike unloads over the crest of the hill) proves that the steering damper works at high speed as well as low speed.

Again I’m blown away by the ‘Blades stability on the brakes as I hammer the anchors into turn nine. But it is here that I lose some confidence through a snatchy transition from brakes to throttle. It is really bugging me. Even more so in the fact that Wayne and Wazza feel the opposite – that the transition is great. It really is doing my head in right on the apex of this turn. They must be carrying more rpm with their faster corner speed through here, smoothing things out.

Anyway, now the fun bit, flat-out up through second and third, just snatching fourth before tipping into turn 10. This thing is so strong and linear – it just keeps pulling and pulling. It trails off around 10,500rpm but from 5000rpm to 10,000rpm it is like a freight train.

Another easy change of direction before lining up 11 and 12, thanks in part to the wide ‘bars and ‘pegs, then it’s a clean run onto the straight again. The bike seems to float down the straight in silence rather than scream down the chute but a quick glance confirms 280km/h again. Fast. Refined. Effortless.

For the Fireblade life is no different on the road. Smooth, comfortable enough for a sportsbike and, surprise surprise, a half decent pillion mount!

For someone so sick of hearing about motorcycles my wife spends way too much time on the back of them and the ‘Blade, despite the absence of anything that resembles a grabrail, is the first sportsbike she’s given the nod to. Ever.

Not only is the ‘Blade our only transport this week. It’s also there to be tested and, despite the pissing rain, we’re off for a 400km loop from Sydney to Mt White, Wollombi, Newcastle, Lake Macquarie and back to Sydney.

The bike feels smooth, safe and tractable as we work our way through some mild Sunday morning traffic in, just in case you missed it, the pissing rain. The snatchiness is still there if the revs drop below 4500rpm but a bit of rear brake helps dampen it.

The upper controls feel well placed and I really like the wide ‘Bars and tall seat. The footpegs are too close to the seat for my legs, though, and sitting upright like this, as opposed to hanging off when riding solo, means I’m doing all the steering through the ‘bars and wasting any ‘peg input.

The Michelins are good in the wet and overall the CBR is performing like a pussycat in these conditions. And I reckon that if the pins and needles in my wrists would go away we’d easily be able to ride this thing all the way to Brisbane. All we’d need is a sheepskin each and a hot meal.

Still in the rain and heading home on the F3 Freeway the CBR spins effortlessly and smoothly at 4200rpm bang on 110km/h. We’re on our second tank for the day of course but we got 240km out of the first one before the light came on.

Rolling into the driveway in the dark, still raining, we both feel surprisingly refreshed so, for a sportsbike, the ‘Blade can’t be too bad as a daily ride.

I did plenty of kilometres solo on the CBR, too, around 1000km of everything from shopping trips to Old Road hammering.

On stock settings the CBR was really nice on the road – plush but still sharp enough to cope with anything your local twisties are likely to throw at you. And the soft (we’re talking sportsbikes here) settings mean you can really use that linear torque curve and stay on the gas while your mates skip off the road trying to feed the power on smoothly on their stiffer bikes.

The overall gearing is good and gearbox action positive and clean. All up a very refined package.

But ‘Blades always have been good on the road.

This time, however, the Fire is only a twist of the wrist away. Pity about the colour. Sorry Honda but I just don’t get the Pearl White. Give me Winning Red any day.

HOW GARDNER RATED THE ’BLADE
In standard factory form I find the Fireblade to be very refined and user friendly – it is a very confidence inspiring motorcycle because it feels easy to ride at high speed.
The ‘Blade has taller gearing or a wider ratio gearbox than most other 1000s which means less gear changes each lap which helps prevent the rider from getting too tired and helped me to ride smoothly.
The power delivery and throttle response is very predictable which also gave me more confidence during initial throttle opening and, once the tyre was spinning, I felt like I had good control over the slide. The transition from brakes to throttle is also very smooth and doesn’t unsettle the bike. Overall the CBR has a very nice, confidence inspiring feel.
The CBR also has a strong bottom end and mid-range but it does lack the top-end of some of its competitors.
But the user-friendly power delivery meant that, on the CBR, I felt really comfortable doing consistent fast lap times and I didn’t get worn out or fatigued. The rear tyre felt more consistent in its grip levels, too, because the CBR is fairly kind to the rear tyre.
The brakes felt strong and gave me good feel and the bike steered well. Turn-in is quite good and mid-corner behaviour is outstanding – the racer-style seating/handlebar/footpeg position is a big contributor to that. Overall the chassis felt well-balanced and confidence inspiring.
The electronic steering damper worked well and the bike responded nicely to suspension fine-tuning. Like most road bikes, the CBR was very soft in the rear and a little hard at the front but after some adjustments the machine was handling the way it was designed to on the racetrack.
Finish quality is very good and I also think that the Fireblade looks great. Overall a user-friendly yet exciting bike for the average road/track day rider

ENGINE
The result of new WSBK rules, the CBR1000RR engine is an extensively redesigned unit. Apart from the cylinder bores and pitch everything has been changed.
An increase in stroke from 54mm to 56.5mm has bumped displacement up to 998cc, increasing torque and broadening the powerband. New forged alloy pistons featuring a highly advanced skirt coating are used and the cylinder block itself is of semi-closed deck design (a first in a motorcycle engine). Nutless conrods are utilised (the cap bolts screw straight into the rod), reducing reciprocating mass. Intake port angles have been raised slightly for a straighter injection path and included valve angles narrowed for a flatter squish band. Valve diameters remain at 29mm in. and 24mm ex. Valve stems were trimmed 0.5mm to 4mm to reduce weight.
Due to the lengthened swingarm the crankshaft, main shaft and counter shaft have been stacked and the crankcases redesigned. A balancer shaft is used to reduce secondary vibration. The more powerful starter motor has been relocated to the right hand side of the engine to improve lean angle. Coolant now enters the cylinder block from the sides and the liquid-cooled oil cooler has been moved from the front to the right hand side of the engine to allow for more liberal exhaust header design. The new cassette-style gearbox is designed to accommodate fast ratio alterations and is more durable than before. The shift mechanism has been moved to the left side of the engine, closer to the gearlever to help provide more direct shifts. Clutch actuation is now via a hydraulic system to compensate for the larger clutch, up from 125mm to 140mm.

CHASSIS
The CBR1000RR has an entirely new frame configuration born from the RC211V and CBR600RR. It comprises of large gravity die-cast sections extending from the steering head down around the engine to its diamond configuration hangers, and then down to the large open-section extrusions in a quassi-twin-spar layout. Due to the separate swingarm resulting in reduced stress the frame is very light.
The swingarm is a work of art and straight from MotoGP. Like the CBR600RR, it carries the rear shock and linkage assembly in the swingarm. This completely isolates the frame from the stresses of rear suspension. Take a look at the pics – it really is amazing. The shock itself is a fully adjustable remote reservoir gas-charged unit.
Up front are fully adjustable inverted forks that are lifted straight from the 2003 model. Offset has been reduced from 30mm to 25mm and trail increased by 5mm. The offset helps the machine steer quickly but stability is retained through the use of the new Honda Electronic Steering Damper, mounted on the top triple clamp. The H.E.S.D unit is revolutionary in its design and was developed by Honda in a joint project with Kayaba.
It comprises of four one-way check valves and a central main valve. Oil can only flow through the vane in one direction and the main valve is controlled by a linear solenoid that receives signals from the ECU.
The front brakes are all new Tokico four-piston radial-mount calipers operated by a newly developed vertical piston master cylinder, claimed to improve feel at the lever. Because of the increase in braking efficiency from the calipers and master cylinder, the rotors have been downsized to 310mm, reducing unsprung weight – as do the new three-spoke wheels.
The ‘Blade also has a new, more compact dash that is based on the RC211V dash. It features LCD readouts positioned around a large tacho dial and digital speedo. It also incorporates an adjustable shift light.
Honda’s brilliant H.I.S.S security system is featured and there is space for a U-Lock under the seat.

FUELLING AND IGNITION
The PGM-DSFI (Dual Sequential Fuel Injection) system features two separate sets of injectors – the first installed in the throttle bodies like on most bikes and the second set positioned up in the airbox, directly above the velocity stacks. Normally, if quick throttle response is the goal, injectors are mounted close to the engine. If maximum power at high revs is the goal, injectors are mounted further away from the ports. With the DSFI system Honda got the best of both worlds – the primary injectors operate up to 5000rpm where the secondary set kick in. The new system also features a 32-bit ECU, replacing the old 16-bit unit, allowing the ECU to control the new ram air duct and exhaust valve. The ECU is also more compact and lighter.
Power and torque across the rpm band are optimised by the use of a ram air duct flap at the mouth of the air intake and an exhaust valve housed in the collector box of the titanium four-into-two-into-one. Both are cable actuated and activated by servomotors.
