Featured Listing – 1976 Benelli Sei 750

Update 8.1.2019: Joe has renewed his Featured Listings. Check out all of Joe’s bikes for sale on RSBFS! Many thanks for choosing us to help move your collection! -dc

Benelli and Honda exchanged flattery in the 1970’s, which began with Benelli creating a six cylinder look-alike of Honda’s CB500 Four in 1972.  Their flagship Sei began as a 750 and progressed to a 900 by 1979.  Honda returned the compliment in 1978 with their CBX.  Restored by a previous owner, this Sei is a magnificent labor of love.

Benelli made a careful study of the air-cooled Honda and made a few changes – the gear-driven alternator, located behind the cylinders, keeps the engine’s width manageable.  With three Dell’Orto carburettors, 76 hp was almost effortless and the Sei created usable torque from 2,000 rpm.  The chassis is a hefty downtube with right-side-up Marzocchi forks, and twin Sebac shocks.  Dual front disks make up for the tried-and-true rear drum.  Styling is dominated by the six-way calliope, with a few angular details on the instrument cluster, side covers, and cylinders.

A bottle of chrome polish might be on the new owner’s shopping list, since the Sei is all metal, with not even the side covers executed in plastic.  On display since shortly after the restoration was completed, it shows almost as a new machine, with sparkling finishes and new rubber parts, like the carburetor boots.  The owner shares these notes:

In general, I do believe super rare Italian motorcycle of the 1970s and 1980s are the future Ferrari of motorcycle collecting. We all know what has happened to Ferrari.

The 1976 Benelli SEI 750 six-cylinder is another one of those iconic Italian motorcycles. It was the first six-cylinder production motorcycle, and, yes, those six exhaust pipes not only sound great but look phenomenal. The bike was restored by a gentleman that spent what looks like half a lifetime to get it to such perfection. This bike starts and runs as it should and I don’t personally know of one important criticism that I could make on the bike for show or riding.

The Benelli winding through the gears sound like a Gran Prix rarer and the slick handling is something has to be experienced. These six cylinder Benelli bikes have a long way to go in terms of collector appreciation. When you buy a first series Benelli six cylinder you will find a crowd wherever you stop.

Then just wind up through the gears and it seems that the roar of those six exhaust pipes can be heard a mile away.

Check out the pictures of this Benelli it has to be one of the best, if not The Best, restored 1976 Benelli SEI 750’s ever!

All my bikes are kept in climate controlled storage and on trickle chargers when not in use so they are always ready to take a day’s ride at a moment’s notice.


Prefer phone calls 847-774-4857

Check out the pictures and be a little amazed – you are seeing the best!

As the 1970’s opened, industrialist Alejandro DeTomaso had high hopes for his new acquisition, and funded the development of the magnetic Sei.  The big-band sound of six individual 125cc cylinders is more like a fleet of motorcycles than just one.  Never destined to be in every garage, the bright light in the Benelli showroom was reflecting off the Sei’s six chrome mufflers.  The owner has curated and preserved this example to a high standard, and not insignificantly, kept it ready to ride.  Please contact Joe with offers at 847-774-4857.

Italian Week Continues: 1983 Benelli SEI 900

We seem to be celebrating an Italian theme on RSBFS this week. That is not too surprising, as pound-for-pound the Italians produce more lust-worthy hardware than most. I’m not discounting the ruthless efficiency of German machines, nor the bright spots in the Japanese flood of scooters; however if you tally up the total number of bikes produced by a given nation and identify what makes you drool, one small country stands out above the rest. Why? A unique combination of passion and performance would be the likely answer. Can we name a few brands that we might like to own? The list is long and glorious: Ducati, Bimota, Moto Guzzi, Moto Morini, Cagiva, Laverda, Aprilia and MV Agusta. That doesn’t even count the bespoke builders of dreams: Mondial, Morbidelli or Ghezzi-Brian. Have I missed one? Probably more than a few. Nobody but the Italians are able to artfully blend the focus of performance with visceral good looks and color. Today’s example is this gorgeous Benelli SEI 900.

1983 Benelli SEI 900 for sale on eBay

Look past the miles-deep pool of red paint. Shield your eyes from the sparkle of the chrome. Ignore the mags, the quarter fairing, the set and the stance. Strip everything away and go back to basics. In this case it is a fabulous 900cc inline six banger. The first to release a six cylinder into production – originally a 750 – the Benelli SEI 900 utilized a larger bore & stroke to provide additional motivational might. With a quarter fairing evoking a period Laverda or Moto Guzzi, the SEI was a technological, aural and visual bombshell of the time. Eschewing the 750’s six-into-six exhaust in favor of a six-into-two, the SEI looked more like a normal motorcycle from the side, although from the front it was all but impossible to hide the width. This seller obviously cares about this bike and it’s history, so we’ll let him pick up the story.

From the seller:
There is a good article that says this is probably 1 of approximately 80 Seis 900s imported to the US. “By the end of production in 1989, fewer than 2,000 examples of the 900 Sei had been built; some sources claim no more than 80 of them made it to the U.S. market.” (Motorcycle Classics, May/June 2015).

1983 BENELLI SEI 900
Built June 1982, titled 1983
VIN: ZBNB0AB00DP011261 Engine No: BGB011248

History:

Original owner (name unknown) bought and rode the bike a little over 9000 miles and then parked the bike in his collection. No significant changes were made. In 1987, second owner (Sterling, MA) bought part of the collection including this Sei 900. The second owner was told it did not run so he stored it in a shop intending to restore it, but never rode it. He sold it to me in mid-2014. I cleaned the carbs, etc. and it started!

I did a complete 1 year effort to do a ground up restoration; inspecting and replacing anything needed except one thing: it has the ORIGINAL BODY PAINT!

Mechanically inside this bike looked like new, still crosshatches on cylinders, great compression, good shifting, etc. Fortunately, the tank was very clean. Outside it had some rust on the frame, wheels, and rear drive chain.

Key restoration items include the following:

– Powder coat the frame and wheels
– All new wheel bearings and brake seals/pads
– Replaced the starter gear and shaft and 2 bearings in the transmission
– Honed cylinders and light valve grind
– New seals and gaskets throughout
– New fork tubes and dampers
– Rebuilt carburetors
– 1 new badge (original missing)
– New seat cover, fuel cocks, and rubber parts
– Re-chromed original exhaust system and other chromed parts

Majority of these parts were original Benelli replacement parts bought from Benelli-Bauer GmbH in Germany.

Upgrades not original style parts include:

– New complete electronic ignition system
– New regulator/rectifier system (original alternator like new)
– New rear shocks
– New rear drive chain and sprockets
– New tires and battery
– K & N air cleaners
– Some new stainless steel hardware

It had 9,272 miles on it when I bought it; it has 10,008 miles now.

Runs and rides absolutely GREAT! Starts instantly, although a bit cold blooded (needs a few miles to warm up). Pulls evenly and shifts fine. And yes, it is as smooth as the books and reviews say.

Sure, in comparison to some Japanese, upgraded-spec, chain-saw razor with pipes and slicks, this SEI is a flat dog. If your idea of riding involves pre-mix and a quarter liter of squish band, feel free to look away. But somehow I doubt a true enthusiast can look at this and not be in awe – even a little – at what Benelli has created. Once owned by the legendary DeTomaso namesake, you can be sure that performance (such as it may be defined) exists within. This seller has done a tremendous job on the restoration of this machine, as well as the presentation. There is strong interest in this auction, and I’m sure a new owner will be celebrating the arrival of a dream very soon. If you’re into Benelli (or even if you’ve only just discovered these marvelous machines), act quickly. Very few SEIs came stateside, and very, very few are in this level of condition. Check it out here, and let us know what you think. Viva Italia indeed!

Six Pack, Brand New ! Benelli Sei 0 miles for 20k Euro (Germany)

Just a few days we’ve introduced the naughty sounding Benelli Sei as opposed to the more common and known Honda CBX 6 cylinder bike. Having six cylinder one after the other one in a straight line, make sure that the forces of of the first and second order are all naturally balanced. These forces are generated by the rotating masses of the crankshaft. The 6 cylinder then, is a very smooth engine and also reliable. It became BMW cars flagship motor until the EU introduced tougher CO2 emission limits that is forcing German OEMs to move toward 4 cylinder smaller capacity engines compensated with twin turbos for higher efficiency. On a motorbike the six inline engine configuration had its technical limits given by the width of the motor and more importantly by the difficulty to cool the inner cylinders in absence of water cooling. They are nevertheless unique, and come with a free revving nature and great sound. The Benelli Sei is in my opinion, the best 6  cylinder out there and I simply love those exhaust mufflers and simple and still modern lines of this 30 years old Italian exotica.

This particular sample is brand new. Not only, it was never driven, it also was never started nor was fuel ever introduced in the tank (no risk of rest then…). It is brand new !

Do I need to say more ?

Let’s hear it from the seller (translated with Google):

Benelli 750 sei. Built in 1976. Absolute new condition. This bike is never ridden. It was also never petrol in the tank. The brake fluid reservoir is virginal.

The bike comes from the private collection of Alejandro DeTomaso. It was spent directly after production there. It was always there in his museum. I purchased it from there after the bankruptcy. It was packed in a wooden crate and shipped to me in Hamburg. In this crate, it is still intact today. The tool kit is fully available. The rubber mounting the battery is boxed under the seat. A battery was never installed.

A photo shows it in the museum shortly before the sale.

The engine oil is Fills and rotates through tadelos. I started the engine nier. The carburetors have never seen gasoline. Nothing is fixed or rot .. The bench aht a minimal small crack on one edge. The tires are original of 1976.

Vehicle papers are available. For questions 0171-3689837

Please do not tell. I have no internet access at the weekend.

I solve my little car collection now on, so I offer it here.

A nationwide shipping is available. The exact shipping cost would then be determined.

The warranty expired in 1977. Therefore: private sale without any Garatie, warranty or return.

Bidders for fun get to do it with my lawyer!

Six the hard way: 1976 Benelli SEI Down Under!

For Sale: 1976 Benelli SEI in Australia

Some of you might be looking at this fantastic Benelli SEI and think that “SEI” is Italian for “CBX.” You would be close, if not a bit backwards. Before the onslaught of the Japanese, and many years before Honda brought forth the mighty CBX, this Benelli six cylinder machine was the techno wonder to behold. Offering 2 more cylinders than Honda’s flagship CB750 model, the Benelli SEI created an instant sensation in the marketplace. It also spawned some imitation. In addition to the CBX, Kawasaki introduced the KZ1300, a similar cylindered beast with liquid cooling).

With more pipes than your local church organ, the SEI certainly makes a statement. It also makes for a very wide motorcycle. However this Italian “copy + improvement” on Honda’s CB-class of 4 cylinder bikes cleverly placed the alternator behind the cylinders rather than at the end of the crank – which helped reduce the width somewhat. Still there is no doubt that this bike makes a very significant statement.

From the seller:
BENELLI 750 SEI 1976, 100% ORIGINAL IN EXCELLENT CONDITION, OWNED BY MY LATE FATHER AND NOW ONLY RIDEN ON RARE OCCASSIONS. NEVER BEEN DROPPED. BIKE SOUNDS GREAT AND RIDES WELL, NEW K81 TYRES. THIS IS AN UNMOLESTED ITALIAN SUPERBIKE FROM THE 70’S WITH GENUINE 30,000 ODD KLMS. BIKE IS LOCATED ON THE GOLD COAST, AUSTRALIA.

With a reported 3,200 of these machines built (spread between 1972 and 1978), this definitely classifies as a rare bike. Performance is adequate at 76 hp – but not spectacular by today’s numbers. Still the sound of that 6-into-6 exhaust as this 750 shrieks to redline is something I wouldn’t mind hearing inside my helmet.

This bike is located in Queensland, Australia – and as such might be a bit of a distance away from most of our readers. However given all of the rare Ducatis and Bimotas that have been shipped Down Under recently, it would be great to get one back!
This particular bike has a opening ask of $10,000 – which is a big initial ask, but probably not out of line with the value of this rare machine. For more details and pictures, click on the link and jump over to the auction. Good Luck!

Stealth Italian: 1984 Moto Morini 500 Sei V

For Sale: 1984 Moto Morini 500 Sei V

Quick: Name an Italian manufacturer of classic vee-twin sportbikes. Chances are that your first response was Ducati. There might have even been some fringe folks who sprung Moto Guzzi to mind. MV Agusta might have been another Italian guess. But how many of you thought of Moto Morini? I’ll bet not too many, mainly because we don’t see them in the US. When we do, it is usually the 3 1/2 (350cc) Sport.

This Moto Morini is a classy, Italian steed. The 500cc, air cooled vee twin is good for 45-50 horsepower. Componentry on Moto Morini motorcycles is generally considered to be well above average for the period – which made the MM expensive compared to other brands. Ceriani and Marzocchi suspension units were used, rear and front respectively. Borani spoked wheels were used on the initial 350cc bikes, later to be replaced by cast hoops. Grimeca disc brakes were fitted front and rear. Veglia instrumentation was fitted standard. The end result was a very high-spec motorcycle, which continues to be an enjoyable mount to this day.

From the seller:
Untouched, all-original Moto Morini 500 Sei-V…down to its Pirelli tires. V-twin, six-speed transmission. Owned since 1999, last registered in 2002. Performance exhaust, 4,777 miles, Owners Manual.

Only blemishes are slight paint bubbling on bottom of front fender, headers could use a black paint touch-up, tachometer is a little loose in its rubber housing, gas stain beneath carb. bowl on engine case.

Recently photographed for inclusion in an upcoming 2012 European Motorcycle Calendar.

The fate of Moto Morini is a long and varied one. From its family origins in 1937, the company was responsible for some very memorable motorcycles and race bikes. Following financial hardship, MM was sold to Cagiva in the mid 1980s. It changed hands again when it was purchased by the Texas Pacific Group (alongside Ducati) in the 1990s. In 1999 Moto Morini fell back into family hands when it was purchased by a company founded by Morini’s nephew (Morini Franco Motori spa). The hard times continued, however, and that company went into bankrupcy and liquidation in 2010. Is this the end of an icon? There is yet another attempt to pull Moto Morini from the ashes as of July 2011; the company was sold to Eagle Bike, a newly formed company that is run by two Italian entrepreneurs. Keep your fingers crossed for this historic brand – we may see new Moto Morini bikes again yet!

The 500cc version of the pre-Cagiva Moto Morini is relatively rare. As stated at the beginning of this post, one tends to find the smaller (350cc) bikes more readily than the 500cc variant. For example, we have posted several 350s over the years (here, here and here), but only one 500cc machine. Like most Moto Morinis we see, this one is clean and well cared for. Mileage is very low, and in general this looks to be in fantastic condition.

Your chance to own a classic Italian vee-twin sportbike is here! For more information, specifications and pictures, click on the link and jump over to the auction. Good luck!

Six Shooter: 1988 Benelli 900 Sei Seria 4

For Sale: 1988 Benelli 900 Sei Seria 4

Located in Kiel, Germany is this wonderful Benelli Sei. If one needed any more proof that the Italians have a style all their own, this must surely be it. Six cylinders, six exhaust pipes, miles of chrome and some neat technological tricks, the Benelli was briefly atop the world in terms of technical sophistication – beating even the mighty Honda. Alas production issues and problems with quality ensued, and the oldest motorcycle factory in Europe (established in 1911) was sold off to Moto Guzzi. The fall did not end there, however, as the Benelli name is currently under control of the Chinese Qianjiang Group.

From the seller:
Hallo,

I’m owner of an Benelli 900 Sei of the last build Seria. The cycle is rebuild with new clutch, piston, camshaft, tires, brake and with an special for the 900 Sei 6-6 exhaust-system from “UK-Exhaust. It’s not the 6-6 from the 750 Sei, it’s specialy build only for the 900!!! The origen exhaust-system in black-chrome belongs to the cycle too.

I think, the transportation in container will cost 1.000 Dollar, but I dont know it exactly at this time. I will have a start price for the Benelli with 13.500 Dollar.

The six-cylinder format devised by Benelli – with the alternator placed behind the cylinders rather at the end of the crank – was originally offered in 750cc. Reports indicate that fewer than 2,000 of the 900cc bikes were produced, and far fewer than that of the final model run. Note that this is a 1988 model, the same year the Benelli plants at Pesaro were sold off, and Benelli was absorbed by Moto Guzzi to form Guzzi Benelli Moto S.p.A. This bike is really the end of an era.

The seller has priced the bike at $13,500 – an seemingly large sum for a Sei. And given such little information about the bike (likely due to lack of English language skills), the opening ask is more about the opportunity to find out more. There are some decent pictures from the seller, but buyers interested in this rare piece of motorcycling history will certainly want to request more.

For your chance to inquiry about this unique Italian superbike, click the link and jump over to the auction. And if you find out more information about this rare beast, be sure and check back and let us know. Good Luck!
