Now we’d like a superb motive and a Grasp Plan: 20 years in the past we simply wanted three cool bikes and an open invitation to California Speedway (which I hear simply hosted its final trackday. RIP.) Earlier we’d already deduced the Kawasaki ZX-6R was the very best 600, the Suzuki GSX-R1000 was the very best 1000, and the Aprilia Mille R was the very best Twin (and the one you most want you’d embezzled). So why not evaluate all of them to one another? Within the fingers of non-professional riders, the outcomes are typically stunning. Miss you, Soiled Sean. Hope you’re nicely within the Las Vegas bunker, Willie T!
What does racing train us girls and boys? How about this: The squeaky wheel will get the grease. All of the complaining Mat Mladin did for all these years in regards to the unfairness of 750 fours having to compete in opposition to liter-size twin-cylinders paid off for the lad, big-time, when the AMA determined dang, perhaps poor Mat’s proper (in fact I’m positive they’d deny Mladin’s feedback had something to do with it), and determined to let full-on thousand-cc fours into the hen home.
World Superbike modified its guidelines over the off season, too, however that august physique handicaps 1000cc fours with 32.5mm consumption restrictor plates.
“The Yanks are so silly and wasteful,” our hero, Mat Mladin, thinks to himself, “leaving all this free bathroom paper right here for the taking…”
In AMA Superbike, Mr. GSX-R will get to maintain all 4 42mm cake holes huge open. You’re not allowed to idiot with the inventory crankshaft, although. Valves need to be the identical materials as inventory, ie. metal, and cams can haven’t any extra raise than inventory.
Sadly for the competitors, metal valves aren’t what limits the mighty GSX-R’s rpm. The poor long-stroke expensive’s bores are solely 73mm huge. Heck, that’s just one mm larger than the GSX-R750, and solely 5mm larger than the brand new 636 Kawasaki.
What does restrict the GSX-R is piston velocity, since its 59mm stroke isn’t all that a lot shorter than an RC51 Honda’s 63.6mm.
“With valves not that a lot larger (or heavier) than these bikes’ both, there’s nothing within the large GSX-R’s valvetrain to maintain it from spinning previous 15,000 in inventory type, identical to the 636.”
Connecting rods, based on our sources at Assault Suzuki, are the weak hyperlink within the GSX-R, and for the reason that rulebook doesn’t handle these objects, you might be positive these quick manufacturing unit GSX-Rs have the nicest, lightest ones cash should buy, pumping pretty 73mm pistons. At that time, it’s Hiya, 15,000 rpm (plus), and Goodbye, bikes attempting to course of the identical quantity of air with a pair of 100mm pistons.
Hey, if Mladin’s outdated 750 was so dang sluggish, how’d he win the three championships on it? Nicely, I hate to say I informed you so, as a result of I truly managed to carry my tongue for as soon as–and when the GSX-Rs didn’t dominate Daytona, I assumed there was a slight likelihood I may need been, gasp, unsuitable. Ensuing occasions, together with watching Mladin’s GSX-R1000 leap off the corners at Sears Level, have led me to have renewed religion in my very own infallibility.
DOWN Simba!
Nonetheless, we took it upon ourselves to conduct additional experimentation. Aprilia’s Mille R, winner of final 12 months’s MO Twins shootout, is new and improved for `03 with radial brakes, a revised tail part, and, and, that’s all.
And whereas we had been at it, why not take alongside the very Kawasaki ZX-6R that received the monitor portion of our current 600 Shootout, the bike that’s carried little Tommy Hayden to victory in each AMA Superstock race run this 12 months? (Making an allowance for that final time we ran a 600 in opposition to an Open-class bike [R1] and a twin [Aprilia Mille R], the little Yamaha R6 was proper within the thick of issues, and actually ran the quickest lap of the day on the Streets of Willow Springs.)

1. John Burns, MO Editor/Cruise Director
Bias: None In any way
Ooooh, ooooh, me first. The Mille R is an exquisite motorbike, and whoever referred to as it an Italian Kawasaki the opposite day must not ever have seen one within the flesh. (Really, Kawasakis are trying fairly rattling good lately too.) Other than the brand new radial brakes, modifications for the `03 model are beauty: blacked out body and swingarm, and a reshaped tail part.
Apart from that nothing actually wanted altering; Ohlins suspension and steering damper, and light-weight and delightful OZ wheels are customary gear. Actually what the Mille wants is extra energy. On tighter circuits or the street, 111 horsies are normally loads, however on Fontana’s lengthy straights, just a few extra can be most welcome.
Come to think about it, these exterior compression-stack offers on the Ohlins fork are new too.
On a day with a stiff easterly breeze, the Mille may solely pull itself as much as an indicated 139 mph operating into the enamel of that gale, down Fontana’s lengthy, banked predominant straight. Apart from a relative lack of steam, nothing else in regards to the Mille R deserves grievance. In my regular trend, I rode the Mille to Fontana that morning, and it’s simply as nice hauling mail as it’s dragging knee.
Wolf down an Egg McBolus, add extra fuel and get on with it. All three of those bikes have radial brakes, and I believe the Mille’s give essentially the most really feel and controllable energy–however that could possibly be as a result of the GSX-R was steaming into corners with fairly just a few extra knots. I received’t bore you once more with what an general good conveyance the Mille is, how skinny and lithe between the knees…
Verify the matching wardrobe…
And the ZX-6R, which makes rattling close to as a lot energy because the Mille and weighs much less, is a fantastic monitor device unto itself.
Had I ridden the little stinger missile out to the monitor that day, nevertheless, I doubt I’d have arrived in such an expansive, congenial temper.
Alas, I’d must get again on the Paxil to journey this one daily.
“As a streetbike, the GSX-R1000 falls someplace within the center, with far superior road suspension and seat foam than the Kawasaki, however nonetheless requiring a little bit of a stretch to get to the clip-ons.”
The Bitter One himself, partaking in a secretive, pheromone-spewing MOian mating ritual.
As soon as on monitor, I’d nonetheless price its ergoes behind the opposite bikes, however none of that stops its 150-horsepower engine from blowing them into the weeds. And right here’s the crux: You realize what I believe swiftly tilted the taking part in discipline in favor of the large four-banger these days? Do you? Unhappy to confess, I’ve truly given this some thought. I believe fashionable, computerized gasoline injection/ignition timing has turned the tide, has taken away the dual’s benefit.
The whole lot I’ve learn and felt with my very own pair of buttocks over time tells me the twin-cylinder benefit was all the time its skill to place the facility down early exiting corners (a factor 600’s are good at too, with their close to absence of torque in comparison with each the larger bikes right here).
As soon as upon a time, when there have been solely carburetors, it was truly pretty straightforward and customary to spit a liter-bike’s rear tire out from beneath your self by getting on the fuel too quickly or simply too awkwardly–a factor made all too straightforward if imperfect carburetion precipitated a sudden spike in energy supply. Even only a small glitch on a strong bike, in case you occurred to be close to the sting of traction, may spell catastrophe. Have you ever observed, or is it simply me, that that basically doesn’t occur so usually anymore? I haven’t seen a superb old school Scott Grey highside/cartwheel into the hay bales since Scott Grey retired. With the arrival of programmed gasoline injection, ignition curves for each gear, the throttle place sensor, etcetera etcetera, you’ll be able to virtually journey the GSX-R1000 as our good friend Pauly Carruthers advises us to journey CBR600s at Las Vegas. “Simply whack it open man. What may occur?”I’m critical. I used to be on the press launch of the, what 12 months was it? `94 GSX-R1100 at Laguna Seca? May’ve been `95… The press corps crashed two of them that I can bear in mind, and there however for the grace of God went I on a number of sideways events. In distinction, on the current launch of the brand new 1000 in Australia, we didn’t lose a single bike–and the brand new 1000 is a lot sooner than the outdated 1100 it’s not even humerus.
2. Will Tate: Flamenco Dancer/Proprietor California Velocity Store
Bias: handler for Aprilia’s left coast check fleetIt was an fascinating day for making comparisons. Regular 35/40 mph wind with gusts to 55/60 mph offered a really uncommon perspective. The brand new GSXR1000 feels smaller and once more lighter than final 12 months’s bike, it’s noticeably slim by means of the tank, much less stress on the outdated hip joints.
The facility supply is extra controllable than I bear in mind–could possibly be the suspension is mo higher and that permits one to throttle up sooner, with out as a lot intimidation because the 2002 bike. This mentioned I had a tough time going quick on the factor.
The key motive for that is FEAR! Two issues saved me off my tempo. First, I used to be experiencing closing speeds into my braking factors that had been superb. I didn’t get the seat time to regulate to those velocities. Second, the wind was knocking me waaay off line. It will push me 4 or 5 toes off line on the banking at an indicated 165. I don’t know why, it simply precipitated me to let off a bit! On the AMA monitor at Fontana the Suzuki’s energy is staggering. I concur with virtually everybody else on the market; the GSX-R remains to be the very best open-class repli-racer beneath $17,999. I must borrow this one for just a few extra monitor days. All that mentioned, I went quickest of those two on the Suzi.
Whiskey Tango bravely bends the beast in at 160-something.
“My private favourite, Aprilia’s Mille RSV R, is a way more civilized bike than some other “off the shelf” bike, interval!”
The Ohlins suspension is as near faultless as I’ve discovered, no undesirable chassis pitching beneath braking or energy. Supple journey with nice really feel for what the tires are doing down there.
There’s no getting spherical the actual fact: Mrs. Miller is a tasty morsel
The brand new for `03 radial-mounted Brembo brakes are as enjoyable because the Suzuki’s motor: one-finger energy at any velocity, linear in utility, and boy they give the impression of being cool too.
Energy supply is typical V-twin–a number of torque to drag you off the nook and good prime finish to get you shortly to the top of no matter straight you occur to search out your self on. I’ve ridden these bikes with the manufacturing unit “off freeway” exhaust, derestricted intakes, and an influence chip, that takes them as much as close to 122- 126 hp–mods I extremely advocate.
Within the wind, this stone-stock Aprilia may simply rise up to 140-something, with much less side-wind impact than on the Suzuki. The Mille didn’t scare me so unhealthy, however the Suzuki’s energy had me operating faster laps.
WT ran his private best-of-day 1:43.2 on the ZX-6R, equalling JB’s finest on the GSX-R1000. Simply goes to point out you one thing or different
We had been additionally lucky to have the 2 new Kawasaki 600-class bikes to pattern: The ZX-6RR and ZX-6R (636). Perhaps measurement does matter, or does it?
I went sooner on the 636 in comparison with the 600, however turned my finest lap of the day aboard the 636 over the GSX-R and the Mille as nicely. I admit I’m a 600 class fan. This new Kawasaki was my favourite final month in MO’s 600 comparo. It flat rips! The one enhancements I might advocate can be 1. A steering damper, 2. brake pads with a bit much less preliminary chunk, 3. revalved suspension, (it’s a tad on the tough facet and the entrance lacks really feel). At that time I believe you’d have the very best membership racer doable this 12 months.
All these bikes are geared up with the most recent gasoline injection methods and none confirmed any signal of switchiness, surging, or hesitation throughout throttle inputs. Carburetors have been round for ever–over 100 years– that’s a number of improvement time. In a couple of tenth of that point, it’s actually superb how shortly motorbike FI know-how has developed.
3. Sean Alexander MO Endurance-Testing Editor
Bias: former manufacturing unit Kawasaki rider
It was with a lot trepidation that I opened the GSX-R 1000’s throttle at California Speedway. You see, I’ve by no means ridden an open class sportbike, oh positive, the occasional Bandit 1200, ZRX, Velocity Triple, FJR 1300, and many others. passes between my legs, however by no means a mega-horsepower race duplicate. Seems, I needn’t have been so involved.
The GSX-R 1000 is a pussycat when ridden with a dose of respect for its 157 horsepower, a Large, Secure, Impartial Steering Tabby that solely desires to inhale straights and babies.
“After my first session, I got here in and remarked to Will Tate that I used to be afraid of utilizing something greater than mild throttle twists off of the corners.”
Will mentioned “Yeah proper, you had been portray black traces everywhere in the racetrack” May have fooled me, the large GSX-R was so steady and calm I had no concept the tire was spinning. That stability (at the least in inventory type) additionally acted to make the GSX-R slower by means of Fontana’s quite a few chicanes, although it did have a chilled impact on my soul, and a peaceful soul is an effective factor if you slam on the brakes (at an indicated 172mph) and flick left for the large chicane on Fontana’s entrance straight.
The GSX-R was the second quickest bike for me, lagging half-a-second behind the ZX-6R. With some extra seat time and one other set of tires, I might have been quickest on the large Suzuki.
This explicit Mille felt somewhat “off” to me. Maybe it’s only a product of being in utterly inventory (learn restricted) tune, or maybe we simply acquired a very sluggish instance? No matter it was, the Mille was the slowest bike for me by a big margin.
Good particulars…
Other than energy, the Mille R was its typical steady, reassuring “unflappable” self. As with most Italian twins, the Mille feels very a lot at dwelling, on the racetrack and I believe it’s the one that may be best for a novice to journey with out crashing.
Ah sure… haven’t we met earlier than? The Kawasaki ZX-6R and I’ve had a loving friendship for the previous few months. Other than it’s inventory suspension and a bent to shake its head, the ZX-6R is simply in regards to the excellent monitor bike, for any monitor this facet of Daytona. In fact priced at eight Grand, the Kawasaki may obtain a prime of the road steering damper and suspension tuning, whereas nonetheless being manner cheaper than the opposite two bikes on this check.
Hmmm, Sean went two-tenths faster on the Kawasaki too — however he put 5000 laps on it previous to his Large Race…
Although the Suzuki is undoubtedly sooner, this little 600 is extra accessable and was straightforward to go quick on, proper out of the field.
At Fontana, even with inventory suspension and no steering damper, the ZX-6R lower the quickest lap time, whereas recognizing 20 mph to the GSX-R on the banking.
It additionally sounds the very best and on tight racetracks it’s one of many quickest road authorized automobiles you may get, no matter value. For my cash, the Kawasaki takes the prize as the very best of the very best.
The Conclusion!
Y’know, if this had been a road check that Aprilia can be your winner.
Enable me to interpret the outcomes if I could: Neither WT nor SA had ever ridden a liter-bike on a monitor earlier than–SA had by no means been on a liter-bike interval, and I believe the GSX-R’s popularity simply preceded it.
With extra monitor time (there’s by no means sufficient), I inform you no doubt each of their outcomes would’ve resembled mine, comparatively talking that’s.
We, okay I, hereby crown the Suzuki GSX-R1000 the Efficiency King of 2003, prolong our congratulations to Mat Mladin on his fourth AMA Superbike championship, and look ahead to a way more fascinating season in 2004, after we hope to see new large fours from Kawasaki, Honda and Yamaha. Barring, in fact, one other eleventh-hour wigged-out change within the guidelines…
Be taught one thing from this. All that good-soldier, suffer-in-silence stuff that was once regarded as noble and an indication of character till the day after the Battle of the Somme, roughly, is completely for the birds in fashionable instances. Making it to the highest requires expertise, however there’s actually no substitute for an enormous mouth and the willingness to articulate one’s grievances. I imply that in essentially the most honest manner.
