Church Of MO – 2002 Scooter Smackdown
Good day, all ye MO faithful, to the first installment of the Church Of MO. In this space every Sunday we will reach back in the MO vaults or deep inside the interwebs for a classic, interesting, or otherwise amusing motorcycle story. Whether or not a traditional faith is right for you, let us be your salvation from the heathens who crossed the double yellows, narrowly missing you on your ride this morning.
Today, we go back to 2002 and revisit that year’s Scooter Smackdown. At the time, small-displacement scooters were a sure-fire way to lose your man card. So it only seemed natural for the gang to get themselves into whatever hoonery was possible with the likes of the Honda Metropolitan, Yamaha Vino, and Aprilia Scarabeo. Follow the link to the original story, or read about the shenanigans below, as we’ve reproduced the original.
But before we do, let us pray:
Before my bike and I hit the street,
I pray that my licence I will keep.
If I should crash before I arrive,
I pray the lord to keep me alive.
2002 Scooter Smackdown
It started simply enough. We had a bunch of scooters, and there were a bunch of us here. We’d ride them all to lunch. We must’ve looked funny, but when you’re on a scooter, you really don’t care. Inevitably, lunch devolved into stoplight-to-stoplight drag races. This would invariably lead to who could get where first. Now before you deride us on our lack of mental fortitude in regards to traffic violations, rest assured that the highest speeds ever reached were in the realm of 43 piston-pounding miles per hour. Downhill. While drafting. And in a full aero tuck. That’s a full, unadulterated 63 feet per second.
The speed of sound at sea level is in the neighborhood of 800 feet per second. So we’re definitely getting close. Anyway, after hours, we’d take all the scooters out back and do mock trials with them all. One person would lead, the other would follow. A swap of the scooters would take place and the whole thing would repeat. Our neighbors would just laugh. And it wasn’t just the neighbors scoffing, our spandex-clad two-wheeled brethren (bicyclists, that is) didn’t think much of the scooters, either: cyclist and MOridian Ashley had a brief melding of disciplines with these machines: “On a recent outing to the local bicycle training spot, I took the Metropolitan and went to the front of a motorpace — that’s where you lead a bunch of cyclists around at high speed to help them get used to riding that fast — and I figured it’d be my chance to dust everyone.
So, I floored the Metro, and it makes lots of gurgly, grindy noises at its top speed, and my friend Mike, the reigning local club champion, got pissed, stood up and passed me! This guy’s doing 36+ mph, looks back over his shoulder with that `who’s your daddy’ angry look, and pedals away.” So, yes, even those boys in funny tights will be passing you with their noses upturned. Heaven forbid you run into one of your buddies that fancies themselves as a “real” biker, like our own Eric Bass: “The ancient Greek philosopher Pliny the Elder once said, `In the days of my youth I was sure of what it means to be a man. Now I’ve reached that age, I try to do all those things the best I can.` … or was it Robert Plant? In either case, I’m 35 now and I’ve pretty much got it boiled down to this: Real men don’t eat quiche, pee sitting down, or ride scooters. Its just that simple. Now ever since I came on board here I’ve been under a relentless assault from the other M0fos about the `scooter hang up’ I have.
“So what’s to hate about scooters?…
…Nothing if you’re a sorority girl at UCLA.”
CrAshley Hamilton threatening to get me drunk and take pictures of me riding bitch behind her on a Scarabeo, Calvin regaling me with tales of his immortal flameout on a Vino (well, okay, it was mostly everyone else telling me about it), even Sean the Intern waxing nostalgic about the time he looped his Zuma behind a bar in Florida trying to impress some chick (word to the wise lad, your chances of impressing a woman ended the moment you straddled that scooter, anything you did from that moment on was a wasted exercise son).
“So what’s to hate about scooters?
“Nothing if you’re a sorority girl at UCLA. In fact I’ve had more than a few moments on campus when I wished I could do that Disney movie thing and trade places with the seat of one of those putt-putts.
You zip up some racing leathers and tuck down low into a lean, mean, time travel machine that can get you from 0 to 100 and back to 0 before the Corvette next to you even hits the century mark.
You slide on some Doc Martin ass-kickers and wrap-around shades and cruise the strip setting off car alarms with your semi-legal Screamin’ Eagle pipes. You DO NOT pull on a Kazoo helmet and sit in that prissy school girl knees-together-back-straight pose that a scooter forces you into and expect to get any props!
“Now in the time honored tradition of attorneys throughout history, I’ve saved the most damning evidence for last. Can we talk performance for a minute? Okay maybe just for a few seconds because there ain’t really much to talk about. Exactly how am I supposed to climb down off of a Ducati 999, squat down on a Metropolitan and feel a tingle of excitement (unless of course I just realized that the Ducati made me ruin my boxers). Hell, I’m pretty sure our own in-house CA State bicycle champ, the esteemed Ms. Hamilton could blow past any non-nitrous equipped scooter on a downhill straight with only her Power Bar fueled pistons and an appetite for (self) destruction. So what is scooter boy left with? The manly rush of exhilaration that washes over him when he calculates how much money he saved on gas? This is America damn it and bigger, faster, louder is the law of the land here. So I say to all the guuuuhrly man scooter riders, ship your Aprilias, Cosmos, and Fiores back to Europe where they belong . . . and take your damn quiche with you while you’re at it!”
Whoosh. That was a mouthful, for sure. But for those of us that could stomach the idea of being scooter wimps, these were just about the most fun you can (legally) have on the street. After all of the unsactioned shenanigans were completed, there would be the unsactioned bench racing. “Man, the Vino is fast out of the corners.” “The Metropolitan has got power off the line.” “The Scarabeo has the best suspension and brakes.” You get the idea. And so it came to pass that we figured street riding is all fine and dandy, but you really can’t judge performance out on the SUV-clad, oil-slick-infested, broken-glass littered, public road system.
Somebody (we think it was Calvin) got the wise idea that we should put together a little course for some (cue the echo, please) serious closed course testing! The course chosen was spread out between two parking lots, involved sidewalks, and about 150 yards of public roads.
Hairpins, S’s, medium and high speed turns, chicanes and long straights where the name of the game. Total elevation change, 1 foot. As for the results of our comprehensive tests? Well, these are scooters after all so we won’t go into specific bit-by-bit detail on suspension valving or engine technology. But ex-intern-turned-newspaper-man Stickie Strong has written a smashing tid-bit on the DITECH system found on the Aprilia. Also, plenty of off-the-cuff remarks by all the testers involved will leave you in; a) a state of laughter b) a state of tears c) a state of fears d) the state of Rhode Island.
Scooters exist to provide a cheap form of transportation to the public. Something that’s non-threatening and easy to ride. It doesn’t hurt that they’re usually extremely fuel efficient — the Scarabeo pulled a whopping 104 mpg, which we measured twice because we didn’t believe the numbers the first time — maneuverable and easy on the bank account.
But, the common viewpoint held by most about scooters is that they’re boring, dull and too utilitarian. Well, we’re here to change that.
A few months back when all we had to ride around town where scooters, we came to this startling revelation: These two-wheeled devices built to satisfy a decidedly uber-friendly group of people could also, in the same way riding mowers do, satiate the need for speed.
It doesn’t really matter which one you pick — the Vino is relatively fast, the Scarabeo gets great mileage and the Honda is the cutest, and an eco-friendly four-stroke.
Overall, the most useful characteristic of all of these scooters are their practicality. They’re cheap to operate, easy to park and they have, for the most part, loads of carrying capacity (note that our Scarabeo was a Euro model, the US one reputedly comes with a basket).
With overcrowding in most urban areas becoming the daily way of life, society, as a whole, will have to initiate a shift in what constitutes an efficient mode of transportation.
Tech Lowdown on DITECH
By Elliot Strong
The Aprilia Direct Injection Technology (DITECH) system is a result of additional research done by Aprilia after acquiring rights to the fundamental technology from Australia’s Orbital Engine Company. Previous attempts at using direct fuel injection on two-stroke engines were not successful — the Bimota V-Due is an excellent case in point.
Advantages of a direct injection system are reduced pollutant emission, increased efficiency, and consequently, increased gas mileage. With the tightening of global emission levels, even on small displacement two-stroke scooters, a commercially successful direct injection system looks quite attractive.
Aprilia is the only company to have successfully marketed such a system. Bimota’s gung-ho venture into the technology was one of the contributing factors to the bankruptcy of the company. Aprilia, on the other hand, has ventured cautiously into the commercial arena by marketing DITECH scooters at first and testing the waters.
Their DITECH system consists of 7 main components: An electric fuel pump; an air-fuel rail; the air compressor; an electric oil pump; ignition system and coil; the electronic control unit (ECU); and a throttle body equipped with a throttle position sensor.
The electric fuel pump supplies fuel to the system at a pressure of about 80 to 110 psi while drawing a minimum of electric current. The air-fuel rail consists of 3 subsystems, the fuel injector, the direct injector and the pressure regulator. An automotive-type fuel injector is used for the fuel injector for reliability, and the pressure regulator ensures a constant stability in pressure for the direct injector, which is really the heart of the system. It is controlled by the ECU and mixes the fuel from the injector with compressed air (supplied by the compressor) to inject it directly into the combustion chamber of the engine at a droplet size of 8 microns. Compare that to the droplet size of a typical car port fuel injector at 50 microns, and you get a sense of the level of precision that this system is dealing with.
In practice, this system leads to improved emissions because the fuel is injected directly into the combustion chamber rather than being mixed with the oil in the crankcase. Additionally, the exhaust gasses are no longer scavenged with the fuel/air mixture, but with pure air, as the fuel is only injected after the exhaust ports are closed, dramatically reducing unburned hydrocarbon emissions.
Because of the precision of the system, the DITECH engines can be run in a severely lean condition. The optimal stoichiometric fuel-air ratio for a chemically perfect burn is 1:14, but the Aprilia system runs as lean as 50:1 at idle and as rich as 30:1 in partial throttle/load conditions.
Now, I can hear all you sportbike junkies warming up your keyboards for a severe tongue-lashing directed towards MO for running a silly scooter story, but hey, slow down there. Scooters like the Scarabeo are testbeds for future technology. There has been rampant speculation on the part of many a two-stroke fan about whether or not Aprilia would apply the DITECH treatment to something a bit more exciting to ride (and that would be street-legal in the US of A)- say, something along the lines of a RS250. But learning from the V-Due debacle, it’s not too wise to throw a bunch of new technology at a high priced sportbike unless you’re quite sure that it will work in the real world. What better way to test this than a scooter that’s used constantly for commuting and given very little when it comes to regular maintenance?
