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.

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!

Six Cylinder Madness: 1983 Benelli 900 SEI

Six Cylinder Madness:  1983 Benelli 900 SEI

Start counting those pipes, now switch hands and keep counting!  This thing must be an absolute riot to do a valve job on.  If you equate the number of cylinders with testosterone then this is as manly as it gets.  Benelli produced this monster from 1983-1988.   If I get the story correct, this bike was produced during the period when Benelli and Moto Guzzi were both owned by an Argentinian business man.  From the sound of it, the six cylinder 900 was the pinnacle of Benelli during this period.  It got high marks for technology and performance but low marks for reliability.

The 900 SEI is said to produce some sweet music courtesy of those six cylinders pumping gases through a 6 into 2 exhaust system.  This clean 1983 model has only 7,100 miles on it. 

This bike has some different pipes on it so I don't know how much that effects the sound but it sounds just plain nasty and I mean that in the absolute best possible way.  The vid is of a nice rebuild with sound at the end.  I can honestly say I've never heard a rumble similar to that.

 

Details on the bike for sale:

This is a duplicate from my collection. The bike is in original unrestored condition, has been very well maintained and everything works. The tires are the original Pirelli Phantoms, good for having the bike on display but not for riding. The brakes and all lights and switches work fine. The special duplex chain and the sprockets are like new. No cracks in the fiberglass bodywork, paint is excellent. The correct original exhaust system (6 into 2) is also in excellent condition, only the number one header has some roughness and discoloring as can be seen in the picture. I do not have any manual or tools. There is no battery included in the sale. In the last few years the bike has only occasionally been used and it will benefit from a full service (cleaning carbs, changing fluids, etc.) and new tires before being put in service again.   

The bike has Georgia registration in my name and comes with a Bill of Sale (Georgia does not issue titles for bikes of this age).

 

No stickers allowed, just real badges.  I love it, just a really cool, unique bike.  Yeah, you aren't going to tear up the track and you aren't even going to be the fastest guy in  a straight line  but that isn't the point.  This is about style points and sound and I think the big Benelli fits in perfectly here.  Some Benelli fans have already found the auction and have bid it up over $4,000.  The seller has a buy it now price of $11,000.  The only comparison I can give you is one that was for sale earlier this year.  It had under 100 miles on it and had a buy it now price of $18,000.  I do not know if it sold or not.

Featured Listing: 1985 Kawasaki Ninja 600R

The seller of this early-run 1985 Kawasaki Ninja 600R recently completed a fastidious restoration of the bike, down to changing the aged rubber charcoal canister strap for an OEM replacement. He also sourced new gaskets for the anti-dive system in the forks, which took some parts hunting, elbow grease and careful planning. The forks got a new coat of paint and fresh seals when the rebuild was done.

1985 Kawasaki Ninja 600R for sale on eBay

The list goes on from there, including freshened carburetors and a couple invisible fairing repairs. The bike was evidently a solid rider before the current owner got ahold of it and made it into a running and riding museum piece. It has fewer than 7,000 miles on the odometer and was looked after properly over its life, so there shouldn't be much cause to worry about engine internals.

These bikes were far ahead of their time when they were launched, and forecasted aggressive riding positions, handling-friendly 16-inch wheels, full fairings and weight savings. By the time the Honda Hurricane came along two years later, Kawasaki was already preparing to refresh the Ninja 600R. The early bikes, known as the GPZ600R in other markets, pushed out about 75 horsepower (some say 76), which was good for 135 mph. The engines responded to revs, and contemporary reviewers said the bikes felt a little flat until the party got going around 8,000 rpm. Keep the engine on the boil, though, and the 600R would sing, and was nimble, if not totally sure-footed, on the tiny 16-inch tires.

From the eBay listing:

Completely original 1985 Kawasaki Ninja ZX600A California.
This is the first year of the Ninja, this model is a first run #2460 made 12/84. It has just 6610 miles. It was purchased in California by the first owner (it has the CA vent box) . I am the second owner and have put no miles on the bike other than test rides.
This is a rare bike in original/collector condition. No resto-queen here, this is the real deal. You are not likely to find another in this condition, and if you do you'll be faced with a great deal of work to get it into this ready to ride condition.
The bike starts and runs beautifully. I wouldn't make it a daily rider, but if you're a collector that likes to run your bikes - this is the one.
I found the bike in great condition, as the previous owner was an older rider who used the bike as a commuter and always stored it inside with proper storage habits.
The bike is in 99.9% original condition, with all original parts or updated OEM parts. It is the perfect survivor, the perfect collector (all original parts that were replaced are included).
This is my 4th nut-and-bolt restoration in the last 10 years (and likely my last). I’m moving to custom builds from here on out. In some ways it was the hardest restoration I’ve done, as I felt it was very important to keep the bike absolutely original and to be non-destructive instead of trying to reach “perfection”. I believe I’ve succeeded to the best of the situation – the following items have been addressed:
Fairing repair:
The previous owner dropped the bike in his garage, resulting in a the left turn signal hitting the wall, causing a silver dollar sized series of cracks around the mounting hole. The previous owner repaired the damage, but it was simply glued and the cracks were still visible.
I carefully grooved the cracks and seams, filled and repaired things properly with a professional plastic welding solution, I filled the area with vinyl body filler and sanded all things smooth.
It was professionally painted (only on the repaired spot) with perfectly matched paint and then clear coated to blend, and properly buffed. It is impossible to see the repair – except on the inside where you may see the weld seams when the fairing is off.
A similar process was followed on the nose cone, where a couple of scratches and rock dings necessitated proper attention. This repair is impossible to see as well.
Tank:
First, the tank has a very small, dime-sized impression on the back/top/left side (see photos) and the blue ring has age cracks (normal for an original bike of this age).
I have replaced the cap and repainted the outer cap ring (old parts included and in near perfect shape). I have also sourced and replaced an EOM fuel-level sending unit from England, as the old one failed due to corrosion.
The tank was fairly clean on the inside, but it was beginning to gather some rust on the surface. It was cleaned with muriatic acid and flushed, but still needed further cleaning – so I recently did a round with OTC rust remover. It’s very clean now.
New OEM petcock was installed as the original was beyond repair.
Forks:
If you are at all familiar with these bikes you know that they included a very complicated anti-dive system (known as ADVS) that used the front brake fluid pressure to dynamically control the compression dampening.
Great idea, but it was prone to leaking and corrosion over time - as there were many rubber parts inside. It is very common for the piston to corrode and leak out onto the fork – as was the case on the left fork of this bike.
As with the fairing, I carefully matched and repaired the paint on the fork, clear coated it, and completely overhauled the ADVS and fork seals with all new rubber (which is not easy to source BTW – OEM parts were found in England and Japan).
Everything was properly painted and overhauled – and all original fork stickers unaffected by the repairs. It is impossible to see the repair.
Brakes:
Just like all the other rubber on this bike, the brake calipers and levers were completely dried out and either seized or leaking.
I sourced all of the proper OEM seals for the calipers and primary/secondary cylinders and overhauled all, repainting a couple of items that showed corrosion.
The rotors were repainted and surfaces sanded and scuffed. Everything looks like new. New brake OEM brake pads have been installed on all three brakes as well (see photos).
Carbs:
The carbs were actually in perfect condition – but just like everything else, the rubber was dry. So, all new rubber gaskets were installed, and new fuel lines (I have placed a filter in-line as an insurance policy – not stock).
Misc:
Plugs, oil, filter, battery, chain, new charcoal box rubber strap (OEM), windscreen is original – outer face was sanded and polished, windscreen trim tabs replaced (OEM), etc. – no detail left out, all parts OEM.
Any small rust/dings were eraser sanded and airbrushed or spot brushed with the correct paint. These repairs are also impossible to see.
As you can see by the photos, everything on this bike is in great shape and very clean. It’s hard to believe a bike this old can still look this clean and perfect under the hood after all these years. It was a bit dusty, so I’ve cleaned literally every nook and cranny on the bike – including the entire motor (which was cleaned with bio-degreaser and toothbrush).
Please feel free to message me with any questions.

If the description doesn't convince you, the pictures will. If you're looking for a pristine version of the ancestor of modern sport bikes, look no further.

Buzz Buzz Buzz: 1984 Yamaha RZ 350

The last street-legal production two stroke sport bike officially imported into all 50 States of the US by a major manufacturer, the RZ350 holds a special place in the heart of motorcycle enthusiasts. It was Yamaha's valiant move to bravely keep the two stroke spirit alive and kicking in the face of tightening emission and noise regulations. It was both a brilliant success and an ultimate failure; a short lived lifespan that stirred hearts as technology passed it by. Enthusiasts who reside outside of the US may wonder at the American fascination with this bike - after all it had been in-market outside of the US for years and would certainly not be considered rare. But unlike grey market imports, this was one model that we could truly call our own. And with bold Yamaha bumble bee graphics and American superstar Kenny Roberts signing the fairing of every one, this one was ours. The RZ350, for all its shortcomings, is a legend.

1984 Yamaha RZ 350 for sale on eBay

If you look at the bloodline, you can see the DNA that evokes the Yamaha RD models that came before. But designed as a modern approach to the "less is more" philosophy, the RZ added liquid cooling to the familiar parallel twin. The two-stroke powerband was (partially) tamed by the introduction of computer controlled power valves, varying the exhaust port height depending upon RPM and throttle settings. Oil injection was standard, eliminating messy mix ratio cups and associated refueling hassles. And there was a secret weapon: hidden in the smart looking exhaust pipes were a complex set of catalytic converters, just like you would find on your car. With the cats (and some air injection), the RZ could sneak into all 50 States of the Union, including the super-picky EPA stronghold of California. Sure, the cans were heavy, they were expensive to replace (i.e. crash damage) and they did not perform nearly as well as expansion chambers and stingers, but they made the bike possible in the US. They were also easily replaced, which is what most everybody did. Immediately.

The RZ350 was intended to compete with the current crop of middleweights; likes of the Kawasaki GPz550, the Suzuki GS550, or even Yamaha's own Seca 550 and FJ600. In that space, the stock RZ was outgunned by the bigger four cylinder four strokes. But the little RZ had agility on its side, and once on the pipe could fare well. But it would never be a great all-'rounder, given the peaky nature of popcorn power. There were many aftermarket and tuner tricks to unleash the beast. Typical tricks of overbores, decking the head to increase compression, and porting were effective. The fact that the Banshee, a Yamaha ATV, utilized the same motor definitely helped with parts availability and knowledge base. But despite the potential, the little RZ was not to be long lived. After a scant two years (and only one in CA), the RZ was pulled from the dealer floors. The party was over, and the used party began. This is where we pick up the story on this bike.

From the seller:
Bought this bike in 2001. Have ridden this bike regularly for 17yrs. Always kept inside. Rebuilt engine because of mileage. I am over 60 yrs old AMI certified motorcycle mechanic for 41yrs. and ride like a grandpa and take care of my things the same way.

- Work Performance rear shock
- Engine Rebuilt 1500 miles ago
- .020 Pro-X pistons,windows cut to match intake
- TDR reeds
- stage 1 porting
- Toomey pipes
- stage 1 dyno jet kit w/2into 1 K&N air filter
- Wiseco Hot Rods crankshaft
- New clutch w/springs
- Full gasket and seal kit
- Race Tech front fork springs
- Chain and sprockets 1500 miles
- New seat cover and battery
- HID headlight
- Powder coated frame
- Bike Dynos out at 59.6 RWH on Dayton Dyno at my shop!
- Spec II Full race fairing
- Fuel tank has no rust, has small quarter size dent and touch up on right front side

Forty Thousand Miles. Let that sink in. Most RZs don't get to that point, having been thrashed, abused, modified, seized and crashed. This particular bike has an amazing number of miles, but looks great. It is clearly no museum collector given the mods, but from a period correct standpoint - hell, from a fun to ride standpoint - this one piqued my interest. The .20 overbore either means the engine had been refreshed once before, or perhaps it was necessary to go that deep due to scratches in the bore. Regardless, that means for bigger pistons and more power. The K&N filter and Toomey pipes are perfect add ons, as is the full Spec II fairing. This bike has been stripped and rebuilt, as evidenced by the powder coated frame. But that just means you are potentially getting a nearly new bike out of the deal.

If you can get past the mileage (40k!) and the non-standard mods, what you are looking at is a great rider. This is a bike that deserves action rather than parking in a museum - although I must admit it looks pretty good. And with a long term owner and a capable wrench (just an assumption, but how many owners out there have their own dyno??), this bike could well be good enough to fill the two-stroke void in your stable. The best part is the price: compared to 90% of what we see on RSBFS, this chainsaw is a veritable bargain. The opening ask started at a reasonable $3k, and bids are flying fast and furious. The Buy It Now price is a mere $4,500, meaning that this bike will likely sell before the auction is over. Check it out here, but better be quick about it. It might already be gone. Good Luck!!
