Ducati 900SS Review

The 900SS Ducati is the Italian Marque's largest capacity 'SuperSports' bike. Ducati refers to it's 748 and 996 range as 'HyperSports' models and these two are clearly a step above the 'SS' range in performance, with price tags to match. 
A two-valve engine is fitted to the 900SS with reasonable bottom and mid-range performance but a lack of a top end urge. Shifting at anything much over around 7,500rpm is wasting time as you are well out of the torque curve by then.  Short shifting is the way to make good progress. 

If you are a power fiend this bike will not suit you in the slightest, any Japanese sportsbike of 600cc or above would comprehensively blow its doors off when acceleration enters the equation. The engine does make good bottom end power but the vibes that shudder through the bike when trying to use the bottom end pretty much render it as a pointless exercise. When trying to pull from 2,500 or 3,000rpm so much vibration goes through the bike that it is hard to read the gauges, not to mention use the mirrors. 
Click to EnlargeSome people refer to this as character, I could think of less kinder terms... The injection system is also prone to having a cough in the air box every now and then.
The engine did receive some updates for the 2001 model year which included totally air-cooled cylinders, split timing belt rollers for enhanced set-up accuracy, new KTM oil cooler, new-design clutch master cylinder, new Bosch timing sensor, improved ECU mapping and a new starter motor ratio.
But it must be said that given a tight set of twisties the bottom end of the Ducati will allow it to stay with most bikes. In this situation less experienced riders may well do better on the 900SS than they would on something like a 600-4. The Ducati would probably also improve the skills of the rider as to get the best out of it you have to ride well and concentrate on being smooth and flowing rather than the more frantic riding style that the small Japanese fours lean towards.
Click to EnlargeThe chassis is taut and reasonably hard sprung, with most road irregularities making themselves felt, sometimes a little too harshly. On smooth blacktop the stiff suspension is a big plus but when any bumps enter the equation a rider will feel every one of them. A lot of weight is placed on the wrists/hands and this discomfort is compounded by the hard suspension. Pillion accommodation is typical sportsbike fare, which is of course uncomfortable but no worse than most other sportsbikes. It seems a lot of thought has been put into the design of the seat, which is well padded and excellently shaped, but the harsh ride makes it work hard. With some suspension work to make it a bit more compliant I think it would be quite comfortable in the butt department but the wrists are another matter. I am quite a heavy rider and found the suspension a little stiff so I would think a person of average weight would feel it even more.
Braking is good but requires a little more effort through the lever than most Japanese set-ups. This is a trait I have found fairly constant through most Brembo braking systems, they work well it is just that a harder squeeze is needed to pull the bike up quick. When taking this into account the stoppers work very well indeed with plenty of power.
Click To EnlargeThe dash layout seems very old fashioned by today's standards but apart from shaking about under vibration they caused me no problems.  You only get a tripmeter, speedo, tacho, temp gauge.  Warning lights for neutral (it lies a lot), oil, side stand, high beam, indicator and fuel.
Quality of cosmetic finish is generally excellent with the duco deserving a special mention. The Ducati's red bodywork has to have the best paint finish seen on any motorcycle. I had luggage strapped to the Ducati most of the time with duct tape on the panels to prevent the bags from rubbing the paint away. Even where some of the tape had gone and in other areas where there was no tape to protect the paint, the full surface lustre survived which is quite amazing. I can confidently say that any other bikes paint finish would have either rubbed through or at least have completely lost all its shine. The Ducati was unmarked; the 900SS will stay looking good for many years.
Click to EnlargeFor 2001 the 900SS gained a 'gun-metal grey' frame and wheels, metallic silver-grey engine, new rear-view mirrors, grey seat, tank protector and 5-spoke wheels.
Click to EnlargeI see the 900SS as the bike for someone who doesn't think they need a lot of power. Maybe a good choice for someone just stepping up to the big-bore class and at a reasonably competitive price. 
But keep in mind that servicing is a little more expensive than on the Japanese opposition.  The 900SS is a sportsbike where keeping your licence does not have to be a constant battle, but still with enough pull for most on the street.

(Nostalgia) Suzuki RF900R Review

The RF900R has one major downfall, most people do not like the way it looks, I think it looks OKAY, some love it, most loathe it. But after you get past that first impression and have ridden the 937cc sports-tourer - opinions can change quickly.
The RF9 was designed to fill the gap between Suzuki's all out fang machine, the GSXR-750 and the long in the tooth GSXR 1100.  It fulfils this role quite well and is a far superior package to the GSXR-11.

On its release the Japanese company had got a bit carried away with itself, advertising that the RF9s looks were modelled off a stingray the designer had seen at an ocean aquarium.  Maybe the Japanese are impressed by such statements, but I think us down here on the flipside just found those statements a bit corny and ridiculous. rf9donkall.jpg (18347 bytes)The engine is quite good, it is now being left behind by some of the better modern engines that are found lurking beneath the plastic of the ZX9RC and YZF-R1. However, It is still good enough to out grunt a Fireblade on the dyno.rf9fcarbs.jpg (8837 bytes)
The in-line 4 cylinder was designed by Hiroshi Lio who also had a lot of input on the GSX-R series of engines. 
He and his team decided that the fitment of small (for a 900+) 36mm carbs would help preserve low and mid-range torque while not sacrificing too much top end.  The 28mm intake valves/24mm exhaust valves are also fairly small for the size of then engine, also for the same reason.rf9chamber.jpg (7156 bytes)
The final drive is quite high for a bike with a sporty nature, 43/15 is the combination of sprockets.
I would be tempted to add a couple of teeth to the rear for some more zap as 5th gear is a tad long.
The acceleration that the engine provides is great, easily the equal of many other bigger engined sportsbikes designed in 1994.

The riding position while not an armchair ride, is appreciably more comfortable than the GSXR-7.
The bike does have a few vibes coming through the grips around the 110 mark but these disappear when you pass 130.
The chassis is a good balance between comfort and fang modes. On standard settings I would say that its handling on very rough roads is a match for nearly anything.
rf9frame.jpg (10474 bytes)The frame itself is painted steel which is fairly rare these days but does look a little classy and is a change from the polished alloy that we normally see.
Brakes are fairly good, but not up to 1999 standard when compared to other bikes that are now it's competitors.  The opposition was bested in most areas when the RF900R was released in 1994, but they have moved on while the RF has stood still.
Fuel range from the 21 litre tank (16 main, 5 reserve) can be stretched to around 300 kilometres when exercising restraint or can be drained in around 220 kilometres if you let yourself get carried away.rf9gauges.jpg (11226 bytes)The dash layout is simple and uncluttered, although how Suzuki's low-spec GSX750F can get a fuel gauge, while the RF can't, I will never know.   The horn is so pitiful it isn't even worth trying to use it.
Suspension had little adjustment to offer up the front, preload is the only offering up the pointy end,  while out back you have 7-way preload, step less compression damping adjustment and 4-way adjustable rebound damping.   I didn't really find that much appreciable difference could be felt between the settings, unlike bikes with higher spec' suspension.
The suspension does acquit itself admirably when a few bumps are thrown in to the equation, the RF9 shrugs them off as though they weren't there and instils supreme confidence in the rider.
The RF does not have the technological brilliance of the VFR 800, but would well and truly shame the VFR when the time comes to press on a bit quicker than socially responsible.
rf9blkfr.jpg (22377 bytes)Finish is not one of the main strengths of the RF900R, but this can be forgiven a little when you consider the lowly $13999 entry price. This gets you a back roads blaster that will not get left behind by anything else on the road, if you are up to the task - so is the RF9. Second-Hand RF9s are selling for around 10k when they are in good condition with low-mileage, this makes them a truly unbeatable Second-Hand buy, in a lot of cases they can be picked up for less than 10k.
If you want a new one, get in quick as they are no longer being imported by Suzuki Australia.  A new one would probably have to come from a dealer who happens to have one on his showroom floor. 
When a bike as good as this can't sell well it shows you just how brilliant all sportsbikes are these days.

Aprilia SL1000 Falco

The Falco is the slightly softer cousin of the more sports oriented RSV Mille and serves as Aprilia's first foray in to the highly competitive V-Twin Sport-Touring market. 
The 998cc  engine revs very quickly and is extremely strong in the lower rpm ranges. But unlike many twin cylinder engines which share that trait at the expense of outright performance the Falco charges on with an extremely progressive curve of power all the way through to around 10,500rpm before smacking the limiter.
These dyno charts show the Falco pitted against the Ducati ST2 and ST4.  On the left is the power chart and on the right is the torque chart.  Click the thumb nailed images to open the full charts in a new window.
Shifting the cogs is a pretty smooth affair thanks to a good 6-speed gearbox that features very short gearing in the lower gears. This makes the bike great around town. However much restraint is required when leaving the lights as the front wheel rockets skywards under any slightly urgent use of the throttle.
The dash is quite well designed with a conventional tacho' in the centre which is flanked by digital displays on either side which contain the speedo, tripmeter, odometer, clock, recorded average speed, recorded top speed and temperature gauges. The fact that there is no fuel gauge is a particularly annoying oversight. A fuel warning light comes on after around 180 kilometres to let you know that around 5 litres remains in the tank which should get you at least a further 60 kilometres before grinding to a halt. On a 110kph@4000rpm highway crawl I would think that the 21-litre tank may well stretch to nearly 300 kilometres.
In the comfort stakes the Aprilia acquits itself very well indeed. After a couple of 300 kilometre stints my muscles showed no hints of soreness. The excellent screen looks too small to be effective but I can assure you that it works very well indeed. I can't work out why it is so effective but Aprilia do spend plenty of time in the wind tunnel so maybe excellence in design is the reason. The comfortable riding position is not too upright, which makes it easy for you to move around on the bike when traversing your favourite stretch of bends.  The Falco is more comfortable than a Suzuki TL1000S, Ducati ST, Honda Firestorm or BMW R1100S.
A serious track day punter would consider upgrading the rear shock but I have no doubt that if pitted against any of the V-Twin Sports-Tourers the Falco would prove quickest at the track. The brakes have excellent strength with a great deal of feel that makes stopping an effortless affair.
I covered plenty of different road conditions during the test including bumpy corners, smooth bends, lots of shitty road-works and long straight stretches to test the comfort level.  The Falco absorbed it all in it's stride and did not put a foot (wheel) wrong.
An optional freer flowing (and magnificent sounding) exhaust system is available from Aprilia for $1,640 and comes complete with injection mapping to suit the new pipes.
Another option that is well worth considering should you be planning any extended touring are the soft panniers for $640. For an extra $170 you can also get the matching top-bag. The tank does not accept a magnetic tankbag but Aprilia can supply a tankbag to suit for $275.
I honestly did not expect the Falco to be as good as it proved to be. At just under $20,000 on the road the Aprilia is around $4,500 more expensive than the Honda Firestorm or Suzuki TL1000S and nearly even money with the Ducati ST4. 
The Falco has a finely balanced chassis with excellent suspension and a decent tank range.  In my mind the Aprilia is clearly the leader of this class and my time on the bike proved it to be a very comfortable, practical and downright fun bike in all situations.
