Featured Listing: 2006 Moto Guzzi MGS-01 Corsa for Sale

1.4.2019: This bike has SOLD! Congratulations to buyer and seller! -dc

Much as Moto Guzzi’s purchase by the Piaggio Group saved the company from possible [likely?] extinction, it also doomed any chance that a new superbike to compete with Ducati or Aprilia would see the light of day. And one did reach the prototype stage, with a narrower-angle, longitudinally-mounted [I will die on that hill] v-twin that improved cornering clearance, with liquid-cooling, four valves, and a chain final-drive. So for the foreseeable future, today’s Featured Listing Moto Guzzi MGS-01 is the closest we will get to a true sportbike from Mandello del Lario.

With no headlight or signals and just a mesh screen covering the air scoop that led to an oil cooler, it’s pretty obvious that the original MGS-01 Corsa is a track-only machine. A roadgoing “Strada” version was supposed to follow, but unfortunately never materialized. In spite of a design that dates back to the early 2000s, the lack of bodywork and unnecessary stylistic flourishes mean it’s aged well and the bike looks very spartan and purposeful.

It’s quite obviously based around the standard Moto Guzzi Daytona powertrain that uses the air-cooled, four-valve “high cam” engine, the V11 Sport’s six-speed box, and shaft drive. But beyond that, it’s had a raft of high-performance parts thrown at it and is stripped to the bare minimum to save precious pounds, and lacks any sort of road-legal lighting. New internals took displacement out to 1225cc and the updated mill was good for 122hp and a staggering 82 lb-ft of torque.

Period reviews of the Corsa were very flattering, with the usual caveat that it wasn’t really light or powerful enough to compete directly with the likes of something like a Ducati 999 in Superbike racing when it was new. So, aside from a couple of race series that catered to big, air-cooled twins, it was really just a very expensive track-day toy. These days, it does fit within the rules for several AHRMA classes, so well-heeled contrarian racers can fly the flag for Moto Guzzi and mix it up with other unconventional sportbikes, as the owner of this example appears to have done.

From the Seller: 2006 Moto Guzzi MGS-01 Corsa for Sale

One of approximately 120 produced between 2004 and 2006. The model was an absolute show stopper at Intermot 2002.Unfortunately, the model only saw a short production run prior to the takeover of Moto Guzzi by Piaggio and was ended soon after. This example was originally delivered in Italy where it saw about 750km of track use and was imported to the US in 2014 by its current owner under a racing exclusion with the EPA which is a bit of a process. The MGS-01 Corsa model was produced for racing use only cannot be legally registered for street use in the US under any circumstances with a hefty penalty if it ever gets the VIN run through. The characteristics of the bike are those of a Hot Rod fused with a race bike. It’s obvious weight number of 420 lbs. disappears once it is rolling and is amazingly nimble. Thanks to the tireless development of the racing program for many years including that by Dr. John Wittner, the disadvantages of having a shaft drive vs a chain drive was virtually eliminated by design of the rear of the bike. The handling is that of a proper racing machine in all aspects. Power is linear from near idle to 8000 RPM’s with torque that lets you pick a gear to suit, showing that a lack of ability to make gearing choices is not an issue. If one chooses to race the bike as its current owner has on occasion, it is a perfect fit for the “Battle of the Twins” class in AHRMA where air-cooled bikes only compete. It also fits in the AHRMA “Sound of Thunder 2” competing with the likes of Ducati 848’s triumph 675’s etc. For the collector only for display, please be aware that the bike as it has a couple of flaws from being used, but is still brilliant and original in it’s overall condition. It has never been down or off track or in the rain, just a mark on the tank cover and a small tear in the seat foam as shown from being bumped off the stand and hitting a toolbox. It also has a small crack at the base of the windscreen which is concealed by the Moto Guzzi decal in the photo. It currently has a Trans Logic servo push button shift unit as the current owner has trouble shifting the bike due to limited foot movement, which is why he is reluctantly selling it. The unit will be removed and no wiring has been cut or modified. Everything is in perfect working order and comes with Michelin EVO Slicks that were fresh at Barber in October 2018 with one practice day on them. The current owner has logged another 750km since 2014. Delivery within a reasonable distance of Southeastern PA can be arranged.

Considering Guzzi’s current status as a “heritage brand” for the Piaggio Group, it’s amazing that these attract so much attention when they come up for sale. Unusually, this one has been modified to suit the owner and has seen some actual racing, which means it’s not completely pristine, but Guzzis are famously durable and a bit of patina adds character. It also means the bike will spared the fate of so many collectible sportbikes, doomed to sit and slowly decay. As the seller mentions, very few bikes were produced, with as few as 50 originally sent to the US to compete in the AMA’s Battle of the Twins series that allowed larger air-cooled twins to compete or, more commonly, to be used as track-day toys or the aforementioned display pieces.

Torque of the Town: 1996 Moto Guzzi Sport 1100 for Sale

With all the 2.3 liter inline triples, 1200cc V4s, and 2000cc v-twin cruisers running around in recent years, 1064cc of pushrod v-twin doesn’t sound like all that much muscle. But back in 1996, when you could buy a Moto Guzzi Sport 1100 new, that was a pretty huge motor, especially for a sportbike. Although many might argue that we’re stretching the definition a bit here for the Guzzi…

Really though, it’s just a different kind of sportbike, one oriented more towards fast road riding and long sweepers than track day scratching or tight canyon thrashes. A more mature sportbike, carrying just a bit extra around the midsection, along with plenty of high-quality components and racing history. I don’t just mean ancient history: the Sport 1100 grew out of the bike developed by Dr John Wittner for his privateer racing efforts in the 1980s. A variation of the resulting Daytona 1000 was released powered by Guzzi’s two-valve pushrod twin, the Sport 1100 seen here.

Earlier versions used a pair of Dell’Orto carburetors but the bike switched to fuel injection around 1996. WP suspension means the bike has stable handling, once you get used to the mild shaft-drive effect and the longitudinal crankshaft. Triple goldline Brembos lack Guzzi’s earlier linked system and haul the 487lb machine down from speed effectively, although you’re still fighting 500+ pounds of beefy Italian sportbike with fuel and oil.

From the original eBay listing: 1996 Moto Guzzi Sport 1100 for Sale 

This is a beautiful and rare collectible Moto Guzzi 1100 Sport in true Italian racing red. Carefully maintained through out its life. This rare collectible is part of a private collection and is being sold as is to thin out the heard in the hopes another collector will snatch this elegant red head and love it just as much as I have. 

Australian made Andrews exhaust pipes fitted makies this Guzzi sing. Rev the throttle and this 1100 sport will give you that heartwarming feeling of a by gone era of motorcycling. These bikes rarely come up for sale especially like one in this condition.

Great condition with low miles makes this the one to have. Small ding in front of tank with a loss of paint can be seen in pictures but in all honesty it barely shows unless your looking hard for faults.

18,713 miles isn’t even broken in for a Guzzi: these things seem to rack up some pretty high mileage, considering the aggressive riding position.  This one looks pretty clean and complete, if a little scruffy around the edges and is missing the airbox, opting for exposed filter elements instead. The $7,400 asking price seems a little bit high, considering other 1100 Sports we’ve seen recently here on RSBFS, but not outrageously so. If you’re looking for an appreciating, practical classic, look no further. The Moto Guzzi Sport 1100 isn’t really any kind of track bike, but it’s a great road bike, with stable handling, torque, and good parts availability to keep it running.

Getting the Shaft: 1996 Moto Guzzi Daytona 1000 for Sale

1996-moto-guzzi-daytona-racing-r-side

Shaft drive has well-known advantages in terms of maintenance and reliability but is rarely seen in the sportbike world as it limits gearing choices and generally adds too much weight to a bike like this Moto Guzzi Daytona Racing. In a world where every ounce counts and bikes are pared to the bone, sacrificing durability for agility, a driveshaft seems a step backwards. But although they played around with a chain-drive, liquid-cooled, v-twin to rival Ducati prior to their purchase by the Piaggio Group, Moto Guzzi was generally happy to just stay afloat and were often forced to work with what they had. Given their financial limitations, they have managed to develop the system to a very high level.

1996-moto-guzzi-daytona-racing-r-side-front

Guzzi was stuck with the durable, but very clunky and outdated five-speed transmission but, in the Daytona, they curbed some of the more intrusive shaft-jacking by using a parallelogram rear suspension, although you’ll still feel the rotational forces of the longitudinal crankshaft as you power out of turns or rev the bike at a stoplight. Because of course you’ll rev the bike at stoplights: Moto Guzzi’s big v-twins are some of the very best-sounding twins on the planet, especially when fitted with a freer-flowing exhaust. The four-valve engine has “OHC” cast into those valve covers, but it’s not really “overhead” and more “high cam” as the cams operate the eight valves via a system of short pushrods and rockers, a system that offered the best of both worlds, with compact dimensions and good high-rpm breathing.

1996-moto-guzzi-daytona-racing-clocks

A bit of a bridge between the earlier Daytona 1000 and the later RS, the “Racing” uses the earlier, hump-backed bodywork with some of the factory available engine hop-up parts. It was never officially available in the USA, as evinced by the odometer reading in kilometers. The seller claims this is is fitted with an 1100cc engine, but I believe all of the Daytonas had the 992cc engine, built to make it eligible for various race classes that limited twins to 1,000cc or less. Production of the Daytona stretched from 1992 to 1995 and saw a bit more than 1,000 examples built, with just 100 of the “Racing” version at the tail end of production for 1996.

From the original eBay listing: 1996 Moto Guzzi Daytona Racing for Sale

1996 Moto Guzzi Daytona Racing, number 100 of 100 ever made 4 valve twin, mint condition. Rare Stay In Tune stainless steel exhaust system, new battery, recent fluid change and tune up, low mileage: 21,446km. Part of large collection that is being liquidated, 1100cc 4-valve twin, this bike is a joy to ride, we at buyer’s expense can ship worldwide. Clean, lien-free title, this is a no-issue bike that is beautiful and rare.

Bidding is up to 7,600 with the Reserve Not Met. No surprise there as sellers are generally looking to get at least $10,000 for nice examples, with one recent low-mileage bike selling for over $14,000! But more often, these Daytonas are a hard sell: they don’t meet their reserve or receive little attention from bidders. Mileage on this example is pretty low, especially for a Guzzi, with a little more than 13,000 miles worth of kilometers rolling under the wheels. The Staintune exhaust may be a bit too shiny for your taste, but they are a quality brand and those… less restrictive pipes should help make the big v-twin sound great and add a little bit more oomph.

Better Living Through Dentistry: 1993 Moto Guzzi Daytona 1000 for Sale

1993 Moto Guzzi Daytona L Side

Today’s Moto Guzzi Daytona 1000 is the living, breathing result of an almost unbelievable underdog story. Italian and British motorcycle manufacturers never seem to lack enthusiasm. But cash? Well that’s always a problem. So while manufacturers like Honda have the financial backing of large companies to drive development and new technology, brands like Ducati and Moto Guzzi are often left without the cash to make their two-wheeled dreams a reality.

So when the time came for Guzzi to develop a serious sportbike to top off their long-in-the-tooth range, where did they turn? To a dentist. In the United States.

1993 Moto Guzzi Daytona R Side Engine

In the mid-1980’s Dr. John Wittner, a dentist and weekend racer was campaigning, for some insane reason, a Moto Guzzi v-twin in ProTwins and endurance racing events. His unlikely successes brought him to the attention of the folks over in Italy, and Wittner was asked to design a new sportbike for Guzzi, using what he’d learned successfully racing these supposedly obsolete machines.

1993 Moto Guzzi Daytona Dash

The resulting bike featured a 992cc version of the classic v-twin with four-valve heads, fuel-injection, and a lightweight spine frame that had distinctive side plates with a characteristic hole where Wittner joked you could store a sandwich… The electronics were stored under that prominent seat hump, and dual-seat bikes looked very ungainly, with a pillion pad perched atop. Best just to go for the solo seat, as seen here.

1993 Moto Guzzi Daytona R Side Tail

Today’s example is a bit dusty, but looks to be in otherwise nice shape and has just 11 miles from new! From the original eBay listing: 1993 Moto Guzzi Daytona 1000 for Sale

[Helpfully translated from Allcapese by the author]

New 1993 Moto Guzzi Daytona Serial #39. Sold on MSO. 11 test miles from the factory. It’s dusty from sitting in my garage for the last 8 years. One in a lifetime chance to buy #39 of 50 imported to the US. I have owned 3… This probably being the last.

Yes, it’s dusty… Yes, it has cobwebs… Yes it may have a few scratches.

Watch for more rare bikes and parts being sold as I have 3 college tuitions to pay for.

1993 Moto Guzzi Daytona L Front Wheel

To be honest, it doesn’t bother me that the bike is a bit dusty. But the seller could at least take some better pictures for us! The Buy It Now price is set at $14,950, you’re looking at some serious change for a modern Guzzi. But this is a historically significant machine, basically ground zero for Guzzis of the modern age: the very first production bike to use both the four-valve engine and the spine frame that was used on sporty Guzzis for years afterwards, most notably on the Sport 1100 that was powered by the two-valve engine.

With just 11 miles on the odometer, I’m sure it’s worth it to spend an afternoon cleaning and scrubbing this one up…

Gentleman’s Express: 1997 Moto Guzzi Daytona RS

1997 Moto Guzzi Daytona RS L side

Moto Guzzi is famous for manufacturing quirky, long-legged sports machines like this Daytona RS. The Daytona featured Guzzi’s 992cc four-valve, SOHC engine that was also found in the bizarrely-styled Centauro. Fans fast Moto Guzzi’s from the 1990’s are probably most familiar with the Sport 1100, the lower-spec, lower-cost version of this machine that was fitted with the bigger two-valve pushrod motor. The fuel-injected engine had a higher, 9,000rpm rev-limit as shown on the white-faced tach but the powerband reportedly featured a frustrating flat-spot at 5,000rpm, right where you’d expect to find yourself on the road. This flat-spot was exacerbated by the standard, not-particularly-slick Guzzi five-speed gearbox that made it difficult to simply ride around the problem.

1997 Moto Guzzi Daytona RS Dash

While the frame and chassis were big improvements compared to earlier Moto Guzzis, by the late 90’s, the rapid pace of sportbike evolution had left them in the dust and the Daytona was too heavy, too clunky, and too slow to keep up with the new kids on the block. Ducati’s sadomasochistic sex appeal and cornering poise allowed it to compete against the Japanese but, compared to its direct rivals, the Daytona RS was really a “slow, old bus.”

With stable handling, good brakes, high-end suspension components, and a generally epic engine, it wasn’t a total loss though. Dripping with character and blessed with a booming exhaust, the Daytona RS was more of a GT and less of a raw sportbike. A flawed masterpiece for sunny morning rides through the canyons while you hold the bike a gear low to keep the revs ahead of that annoying flat-spot, riding a bike that makes you feel special.

1997 Moto Guzzi Daytona RS R side Engine

This Daytona isn’t perfect, but looks to be well cared-for example and includes some interesting features, and the fact that it needs a bit of cosmetic attention wouldn’t bother me, as it’d be a chance to go back to a more traditional eagle logo on the tank. While the bike originally was available with a passenger pad and pillion pegs, this bike’s solo tail is possibly for the best: passenger accommodations were supposedly very poor…

The bike features head-guards, although I’ve never seen this particular, abbreviated style before. On two-valve Guzzis, these actually do more to protect the spark plug leads than the heads themselves, allowing victims of low-speed crashes to get back on the road running on both cylinders. The four-valve engine’s plugs are more recessed, but the guards should still protect the heads themselves in a crash.

1997 Moto Guzzi Daytona RS L Termi

The sound of any uncorked Guzzi twin is truly epic, and the genuine Termignoni pipes fitted should give this Daytona the ability to shatter windows from blocks away.

I’m curious about those front brakes: they look like six-piston calipers. The bike was originally equipped with the standard package of Goldline four-piston Brembos common to many Italian bikes of the era, although the Italians are notorious for fitting non-standard bits partway through a production run, so perhaps these are original?

1997 Moto Guzzi Daytona RS FI Detail

From the original eBay listing: 1997 Moto Guzzi Daytona RS

1536 original miles, clean title with paper work, I was told by a collector that only 308 were made. The bike is in very nice condition, runs extremely strong, but will need to be repainted due to the fact it was dropped over in the back of a truck and has some scratches and 2 indentations in the tank. The turn signal are tucked under the tail fairing, but are still there. This is the solo seat version with a dual Termignoni carbon fiber exhaust system. The motorcycle has just been serviced and will be getting new fork seals before this auction is over.

There are two days left on the auction with no takers yet at the $6,000 starting bid. While the $12,000 Buy It Now price might seem steep for a 90’s Guzzi, this bike shouldn’t be confused with its more common two-valve sibling: the Daytona RS is really the ultimate incarnation of the spine-framed Guzzis. Although this example has a few minor cosmetic issues, the low miles and general quality of the bike make it a tempting place to start if you’re looking to complete your collection with one of the best-looking Guzzis of the era.
