Honda CBR929RR – The First 40,000 Kilometers

 

I guess we are past the initial impression stage now. My overall impression is complete reliability, easy to ride, good steering and handling, and is easy to live with. It still starts at first stab, idles around 2000 rpm and drops back to 1050 rpm when warm. I normally ride it away cold, enough torque to easily cope. It runs on unleaded petrol happily enough. Fuel economy hasn’t improved – around 15 km/l though I suspect if I ran premium unleaded it would improve.

 

The gearbox still clunks in first and second, particularly at low revs. It is still a bugger trying to find neutral around town. If you are stopped it will either hunt from 1st to second to 1st etc or else it won’t budge at all. I have learnt to drop into first while the bike is still rolling – at around 20 km/h. The gearbox gets even more clunky when the oil is worn – not old, as it is never more than a few months old when it is time to replace it again. On the positive side, the initial fuel injection jerkness has disappeared as the engine has loosened up.

 

The switch gear is too light and fiddly. I still bump on high beam occasionally and the blinker switch is sticky but tolerable. I have stopped bumping the horn.

 

The screen surface is too soft and scratches if you look at it. There is nothing you can do about it.

 

On the plus side the security lockout key system has worked faultlessly, the Hallmark rack and bag have worked well, all the instruments and lights have worked almost faultlessly – I replaced one tail light, ground clearance hasn’t proved an issue, and the only thing to vibrate loose has been the subframe – 4 large bolts. Other than that, everything has worked as the manufacturer intended.

 

Security ignition key. A card-reader type ignition lockout is fitted as factory standard.  The key has the card built into it.  The normal method to steal a bike is to use a hammer and a screwdriver to break/turn the ignition on.  This method won’t work on the Fireblade.  You must have the key to start the bike.  It is surprising what confidence (justified or not) that this affords the owner.  Eg just roll up to the footy and park it anywhere.

 

Automatic choke. Having to guard against the engine racing while on manual choke was always irksome.  The automatic choke maintains a fast idle (2000 rpm) slowly reducing it as the water temp. rises.  The motor fires first time, every time and has enough torque to ride away from cold.

 

Digital display. I was always taught that an analogue (needle) display was better and easier to read than a digital display and figured it would be one of the down sides in the quest for weight and cost savings.  Not so.  The large format digit speedo display is easier to read, particularly at speed, and with more accuracy. It seems to sample at every 1/2 or 1/3 of a second.  So during acceleration or braking it is playing catch up.  Two trip meters are handy as is the clock and digital water temp gauge.  (The bike runs at 82ºC normally and on really cold and wet days drops back to 78ºC.  The thermatic fan chimes in around 103ºC (I think) and the engine shuts down at 130ºC!).

 

 

Now for the serious stuff:

 

This 40,000 km has been accumulated in the last 14 months on Club rides, weekends away, and a small amount of commuting – no more than 4500 km, up and down the Freeway to work, mainly two-up. So about 90% of the riding has been sport touring with the Club. Weekends away pile on the kilometers – usually more than 2000 km each time.  They also destroy the tyres at a much faster rate than weekly Sunday rides due to the sustained high speeds and consequent cornering loads.

 

Hence, tyre consumption has been fairly dramatic. See table. I am onto my 9th front and 12th rear tyres. All bar four tyres have been second hand, usually ex-race. I am mentally happiest with the Dunlop 207RR on the rear – treaded pattern, grip lasts till the end, around 7000 km life. The Bridgestone 010s are very good as well in terms of grip, but wear fast on the rear. Front’s are fine – over 10,000 km on a near new second hand one. I am getting very reasonable wear out of Michelin Pilot Race tyres, both front and back. They have lots of tread compared to some other brands, and I have never had a “moment” with them, wet or dry, despite the lack of cuts.

 

Over the 40,000 km engine maintenance has been pretty slack. Oil changes are nominally every 6,000 km and I think I started out that way, but missed one when we were moving houses and there were plenty of bike trips away. Oil changes are easy – the fairing does not have to be removed to get to the sump plug or the filter. Just as well because the fairing is time consuming to remove with its various delicate screws and push connectors. The bike has had a few oil filters – not cheap.

 

It has still got the original spark plugs – though I attempted to change them and only got as far as removing the tank – petrol everywhere – no tap to turn off. The plumbing associated with the injection is fairly obstructionist, delicate sensors everywhere. I think when it comes time to do the valves – every 24,000 km nominally – they can change the plugs as well! The valve train is so light that the word is that they almost invariable don’t need adjusting. On simpler bikes I would do the valves, but access is extremely time consuming and fiddly on this bike – time I could better spend riding!

I changed the rear pads at 21,650 km and the second Kevlar set are about 2/3 worn. I changed the front pads at 39,465 km and replaced them with the originals. They retail at about $105 a set compared to about $50 for aftermarket ones. I would be interested to see if anyone has tried Nissan aftermarket pads. Supposedly they are the same compound as the originals. Given that the calipers are Nissan, this could make sense. And they are half price. Incidentally, the brake fluids were replaced at 25,118 km.

 

At 26,950 km I replaced the chain with an EK ZVX 530 which the dealer claimed had the same characteristics as the equivalent RK chain (my preferred) but at a cheaper price. I rotated the front sprocket but it was on its last legs so I replaced it with a genuine one costing $34 at 31, 964 km. The rear sprocket is fine.  I have adjusted the chain only once since replacing it.

 

I checked the air filter at 39,000 km – while I had the tank off – and banged out the larger stuff – spiders, small birds. It looked very expensive – molded plastic, large plate arrangement, paper element.

 

I changed the fork oil at 18,157 and again at 35,143 km. These intervals are too far apart. My feeling is that you should not let the oil go longer than the recommended 12,000 km. The first time I did it myself, the second time I gave the forks to Rod Sharp at Cycleworks. Upside down forks are a real physical struggle without the right tools.

 

I replaced the rear shock absorber at 19,538 km with a new hydraulically adjustable Ohlins, retailing around $1650. The damping was fading when hot, and the shock had a general vagueness about it. Though the original was still serviceable, the new one rode better and handled superbly. I had retrieved the Ohlins out of the ZXR before selling it and thought it could be modified but a direct trade was the more economical solution. My old one had recently been rebuilt and despite 100,000 km was still worth a lot of money, defraying the price of a new one significantly.  It is a set-and-forget item. I have not touched it since installation – a non-trivial exercise – another half a day in the garage.

 

I greased the steering head bearings at 21,650 km after noticing they were notchy. Thinking they were damaged I purchased a replacement set and discovered the originals are ball bearings and the replacement ones are roller bearings. Roller bearings are much better from an engineering point of view – they offer line contact rather than point contact – but provide a slightly heavier feel to the steering. And feel is a marketable commodity. The original bearings were in fact okay, just over- tightened. I have kept the replacement bearings for a rainy day – probably around 80,000 km at this rate. The original ones are working fine, and, as long as I don’t learn how to do monos, should stay that way.

 

I also greased the rear suspension linkages - nice roller bearings – at 35,143 km. The suspension was squeaking as Julie climbed aboard. Lubrication has fixed it. I use Shell waterproof grease – the last lot cost $4.00 a tub and lasts forever. It works really well on the chain as well.

 

 

Well, that is about it. I have covered the consumables: chains, sprockets, pads, oils, plugs, filters, and tyres. Suspension components – forks and shock. Niggles: economy, switch gear, turning circle (huge). The good bits – the reasons I bought the bike in the first place - are still holding true: handling, low weight (under 200kg wet, claimed 170 kg dry), brakes (woppers), power delivery (excellent low and mid-range), reliability, digital speedo – large and clear, always readable clock – don’t have to push a button like on Suzukis, large boot space, neat after-market rack arrangement, ignition lockout system, automatic choke.. The good bits far outweigh the niggles resulting in a bike that is easy to live with and easy to ride, allowing me to concentrate on enjoying riding while having complete trust in the bike.

Factors high on the wish list were, in no particular order:

1)      Four cylinders (from limited observation TLs and VTRs (twins) get poor fuel consumption, TLs destroy tyres, and everyone crashes them!);

2)      Fuel injection (carbies ice up, get fluffy, float levels and regular synchronising to worry about, generally higher maintenance than injectors); injection offers altitude compensation 

3)      Power delivery of a four - available up high if you need it, otherwise relatively docile and predictable in low and mid-range.

4)      Good handling (upside down forks, light weight, steering geometry)

5)      Proper wheel sizes (nine years of 16 inch front wheels on earlier model Fireblades had put them out of the question, other than to fit a CBR600 front 17" wheel.) 17" rims provide access to second hand race tyres at affordable prices.

6)      Price was a serious consideration.

7)      Brakes. Good ones.

8)      To a lesser extent, ease of maintenance, warranty, and local dealer access.

 

User-friendly Honda touches:

 

Hinged rear seat “glove box”. Best under seat storage on a sports bike I have seen.  I fit a large can of chain lube, a large can of Mr Sheen, the Honda tool kit, a cleaning rag, a container of spare nuts and bolts, a sun cap, Club itineraries and wet weather pants. Magnificent.

 

Security ignition key. A card-reader type ignition lockout is fitted as factory standard.  The key has the card built into it.  The normal method to steal a bike is to use a hammer and a screwdriver to break/turn the ignition on.  This method won’t work on the Fireblade.  You must have the key to start the bike.  It is surprising what confidence (justified or not) that this affords the owner.  Eg just roll up to the footy and park it anywhere.

 

Automatic choke. Having to guard against the engine racing while on manual choke was always irksome.  The automatic choke maintains a fast idle (2000 rpm) slowly reducing it as the water temp. rises.  The motor fires first time, every time and has enough torque to ride away from cold.

 

Digital display. I was always taught that an analogue (needle) display was better and easier to read than a digital display and figured it would be one of the down sides in the quest for weight and cost savings.  Not so.  The large format digit speedo display is easier to read, particularly at speed, and with more accuracy. It seems to sample at every 1/2 or 1/3 of a second.  So during acceleration or braking it is playing catch up.  Two trip meters are handy as is the clock and digital water temp gauge.  (The bike runs at 82ºC normally and on really cold and wet days drops back to 78ºC.  The thermatic fan chimes in around 103ºC (I think) and the engine shuts down at 130ºC!).

 

 

Niggles:

 

The blinker switch is too small and sticky/stiff for winter gloves.  It seems to be a common Honda switch gear problem.  The high beam switch is too sensitive and is regularly bumped on when hitting the indicator switch.  And the horn is pretty sensitive too. (But I seem to be getting used to these idiosyncrasies as I have not had a problem in the last couple of weeks.)

 

Positive neutral lockout. Having ridden Kawasakis for 20 years, and then not being able to go from first gear to neutral every time when sitting at the lights is a shock to the system. The Honda is a mongrel to find neutral on. All the usual tricks fail. I sometimes switch the motor off, change into neutral and start again! (This seems to be getting better as the gearbox loosens up.)

 

Fairings are an unnecessary pain to remove.  Why do we have to have 4 or 5 different size screws/clips.  The Kawasaki had two sizes.  Apparently Ian’s ’99 model has those quick release fasteners. And the screen scratches at the slightest provocation - you can scratch it with cotton undies. I have given up worrying about it.

 

Fuel economy is not startling.  On Club rides I average around 16 km/l hitting reserve at 230 km.

 

The EXUP valve rattles sometimes, but it is normal.  Most noticeable at low revs.

 

As per modern bikes, the radiator does not have a stone guard, but at least it is mounted high and seems half as big as the Kawasaki’s (and hence half the risk of getting holed).

 

The mirrors go blurry at 105km and come good again at 6000rpm or 150 km/h.  Annoying.

 

Tyre wear.  Front 010’s lasting 7,000 km, onto 3rd.  Rear tyres lasting half that.  Very impressive original equipment Battlax 010’s and 020’s.  I was offered a choice of tyres, Michelin Pilot being the other option .  Who’s ever heard of optional fitment tyres? Excellent..

 

 

Good bits

 

330 mm monster front disks with larger master cylinder than previous models to give better feel.  They actually feel spongy but are very powerful.  At first I was disappointed by the sponginess but since hearing the rationale I feel much happier. Still on original pads front and rear, but rear going.

 

Titanium exhaust bits.  The bugbear of the Kawasaki was the 10 kg exhaust muffler canister, which, due to its weight and poor mounting design, would fatigue the mounting brackets including the collector/muffler flange, and the footpeg mounting bracket.  The Honda exhaust system has lots of titanium, aluminium and stainless steel and hot bits burn bright blue. It has an extra mounting point reducing the flex, and, combined with the low weight cannister, should prove very reliable.

 

The motor.  Turbine smooth.  Very responsive.  Not overly powerful – or at least very controllable.  Deceptively fast.  Opening the taps induces a seductive rush of power. Good bottom end power (EXUP valve in the exhaust, Suzuki style flapper valve in the airbox, all helping no doubt.) Pulls cleanly from idle. Mini flat spot at 2000 rpm if you try hard to find it. Fixed by removing "spark arrestor" (cone of metal) from muffler I've heard.

 

Non-pressurised air box.  Fantastic.  Saves on air filters and plumbing complexity.  The amount of dust, bugs and moths that were forced through the Kawasaki air filter had to be seen to be believed.  For the theoretical couple of horsepower gain, who needs the aggro.

 

Suspension.  Handles pretty well straight out of the box – still at original settings, though did check them against an American recommendation and found they were even stiffer than what they recommend on the front. I have bumped the rear pre-load a couple of clicks.   There seems to be some changes between the 2000 and 2001 models which Honda is not advertising.  For instance, the Americans think it has gained 6ps and I think they have tweaked the standard suspension settings.

 

Nevertheless, the front springs are right on the margin of softness, and I think the rear damping is going off, particularly noticeable two-up.  Springs and oil will fix the front; maybe the Ohlins out of the Kawasaki can be made to fit.  That is the future plan.

 

Gearbox. Very light and precise at any sort of revs above 3000. Below 3000 it is clunky, particularly first and second gears (probably savagely undercut).  And the aforementioned no neutral finder. Only noticeable around town. There seems to be a fair amount of drive train freeplay as the chain slops around, again less noticeable the better the gear change.

 

 

Maintenance:

 

My feeling is that motorcycles are over-serviced.  According to the manual, one should check the shims at 24,000 km and also replace the plugs at 24,000 km. DOHC, fuel injected, water cooled, universal Japanese motorcycle. Bugger all to service. Suffice to say, taking this theory towards its logical conclusion, and having an off-the-record talk to the mechanics …fluids and filters. Maintenance costs are negligible compared with tyre costs anyway. Service intervals are nominally 6000 km.

 

Conclusion:

 

The proof is in the eating.  The Kawasaki proved ultra-reliable, its only vices being an appetite for fuel pumps (horrible points design) every 60,000 km, breaking muffler brackets, and an appetite for sucking stuff into the carbies resulting in regular cleaning.  The Honda has proved reliable and easy to ride and live with so far.  Roll on the good times.

 

ZXR? Eventually sold unmodified (not even washed!) with full disclosure. Apparently it was back on the road after one weekend's solid work. The frame had snapped completely through and was welded up. The original near new fairings were refitted, spare front wheel installed, odds and sods such as headlight mounting plastics repaired, carbies sychronised and battery charged. One happy owner last seen riding it to the World Supers at Phillip Island.
