I've always liked the Mille - found this at 2WT:

2004 Aprilia Factory Mille

Getting Better With Age

I guess the first thing to do is explain a little about the 04-model designation to avoid any confusion. Last year, the “R” was the top of the line Mille, featuring upgraded Ohlins’ suspension and lighter OZ racing wheels. With an abbreviated sub-frame and various carbon parts for further weight saving, the bike cost $3,800 more than the standard Mille. This year, the Aprilia Mille “R” is going to be the base model, with the “Factory” as the limited edition flag ship Mille. Wearing top-shelf Ohlins suspenders and steering damper, the price differential this year is $3,900, with the “R” priced at $13,999, and the Factory at $17,899.

Conflicting schedules meant I missed the original press launch of the new bikes in Las Vegas, but Aprilia’s Robert Pandya quickly came to the rescue a few weeks later with a phone call. If I could make it over to Charlotte, North Carolina the next day, he could let me have one for a couple of weeks. Twenty-four hours later I was running hard and fast, blasting up through the Pisgah National forest on my way home.

I’ve now rode the Factory on the track twice, though both times it was on fried rubber from previous journalist testing and it felt like being on a roller skate in the rain. Robert Pandya to the rescue again: new Pirelli’s fixed everything, elevating the Factory to the easiest and most enjoyable bike ridden on the track this year. I am not saying there aren’t faster bikes; the Factory just has the best balance of power, handling and braking for my personal tastes. Four cylinder liter bikes are so brutally fast, and powerful, there is little room for error on the track, whereas the Aprilia is a lot more forgiving if you err. Sure it will spin up if you are too heavy on the gas and can hit some big speeds quick, but with its Ohlins’ suspension, radial brakes and race inspired frame, it never feels out of control.

Hidden away between the sculptured frame rails, is a new engine called the V-60 Magnesium. Replacing the tried and tested V990, it is still essentially the same longitudinal 60-degree V-twin, with 4 valves per cylinder and double overhead cams, it has just undergone some changes in the quest for the quoted 139 horsepower. Starting in the cylinder heads, Aprilia has drawn from its success on the racetrack to make the combustion chambers more efficient. Enlarging the squish area between the intake and exhaust valves allows the new engine to require only a single spark plug. Camshafts are also new, as are the valve springs, although valve sizes remain the same.

Getting fuel into the cylinders, 57mm throttle bodies, up from last year’s 51mm, get new intake ducts and a single injector per cylinder. The pressurized air-box is also said to give an extra 3% increase in power once on the move. Electronics are managed by a new ECU that takes its information from 15 different sensors, before being passed through a CAN line (Controlled Area Network) to an auto diagnosis terminal located in the instrument panel. The net result of all these changes is a highly responsive engine with smooth power that unlike previous Mille’s really kicks on top. On the track with high rpms and lots of full throttle applications it is about as perfect as it could be, but on the road it does have one area of weakness.

Running down hill in a low gear at high rpms the bike feels as if it running lean or low on fuel, and getting back on the throttle the bike seems to hesitate a little. Keeping the bike in a higher gear, hence lower rpms, and using more throttle cures the problem, but is not always practical traveling down steep mountain roads. Riding up hill with a fuller throttle on the other hand, the power delivery is so rich, sumptuous and smooth, you will think you’ve died and gone to heaven, with 5,000 rpm being the magic number. At this point in the power curve the bike feels totally relaxed.

The Factory and the standard “R,” actually share the same basic chassis geometry as last year’s model. Subtle changes abound though, with the headstock repositioned to lower the bike. Further lowering has also taken place in the swing arm mounting and the swing arm pivot has been moved forward 0.5mm. The engine now sits 4mm further to the right to complete the changes, and the sum of all the parts adds up to a very different feeling bike. One of the most noticeable improvements is the way the bike turns in to fast corners. The old Mille always felt as if it wanted to run a tad wide asking for a little muscle. The Factory doesn’t exhibit these tendencies and also feels a lot more nimble out on the road. It is also a lot easier to ride around town and in traffic. The whole throttle, gear-change, steering-input package just seems to work together better, making the big-twin fun where I felt the “R” to be work.

On the track or on the street, it is all but impossible to fault the Ohlins suspension, or the four-piston radial brembo brakes for that matter. The 43mm forks allow adjustment for spring pre-load, compression and rebound damping, and only on the track did we dial in more pre-load and slow down the rebound damping a little, as the stock settings were perfect for road work. Stiction is kept to a minimum with the fork legs coming titanium nitride coated, and there is a total of 120mm of travel available. Keeping the rear wheel from misbehaving, the Ohlins shock out back gets adjusted the same way, and has a piggyback nitrogen cylinder built into the body. I had no reason to touch the steering damper, as no matter now hard I got on the throttle I never experienced any headshake.

First seen on an Aprilia 250GP bike, radial brakes are becoming more common these days and once you have used them you won’t want to go back. Providing incredible feedback at the lever with eyeball popping stopping power at the pads, the brembo-sourced items are absolutely first-class. Using four individual pistons pushing their own brake pads, the radial caliper doesn’t experience any flex, therefore the pads stay more in line with the 320mm discs for better braking and extended life. The adjustable lever is light to the touch, with enough travel for trail braking before the pads really start to bite down.

Dry weight is quoted for the Aprilia Factory as 407 lbs. and this is no doubt helped by the liberal use of carbon fiber. No complaints here as the bike is visually stunning, once I got past the funky looking front air intake. The wheels are also a source of weight saving with a claim that says they are “25% lighter than the lightest wheels on the market.” Aprilia even went as far as to anodize them instead of painting to save weight.

As well as being light, the Factory is extremely narrow and this is helped by the use of the integrated turn signals in the mirrors up front and the sleek, sexy looking tail unit out back. The mirrors themselves, in the Italian style of “what’s behind doesn’t count,” are truly useless offering wonderful views of your arms. The taillight gets its own award for being the coolest looking taillight on a motorcycle, as does perhaps the whole rear tail section.

Up the other end, I found the cockpit area a little ugly, although the digital speedo/conventional tachometer unit is tidy enough. Shift light comes on at 10,200rpm with red line hitting at 12,000rpm; so there is some useful over rev. The usual funky Aprilia upside down horn and turn signal switches will provide some fun, as you honk to change directions and flash to warn on-coming motorists for a couple of days. There is also a lap counter you can play with during track days, but unfortunately I didn’t get to try it.

Fast, expensive and exotic, the Aprilia Mille Factory is a motorcycle for the serious Italian sport-bike aficionado. Beautiful to behold, and even more beautiful to ride, there are only going to be a limited number coming to this country, so ownership is going to be the ticket to a very exclusive club.

This looks like a pretty hot ride...but damn, it sure looks uncomfortable..
Hard to say. My '00.5 is not bad at all. Much more comfortable than my RC-51 was.

This article makes me want to ride an '04. My old dog rides so well that I can hardly imagine the improvements they're talking about. I'm sure the larger throttle bodies must hurt the mileage a bit. I get incredible mileage on my '00.5.

Posers ride aprila no love lost here if they go under and there is no more mille
Hmm, that's funny. If you go over to the Aprilia board you will find that there is a HUGE percentage of the members who actually ride sportbikes where they are engineered to be ridden. On the track. MANY race Aprilias. MANY do track days on them. I'd be very interested in seeing what percentage of Aprilia riders actually ride on the track compared to the percentage of various Japanese manufacturers... It'd be an interesting study, that's for sure...

There's gotta be a study on that somewhere on the net.. I'd be interested to see that info too. I'll see what I can dig up! :cheers:
