With Papers: 1983 Benelli 900 SEI

Kicking this post off with a provocative statement, I’m not sure the world realized what a tremendous talent we had in the form of Alejandro de Tomaso. While the Italian started life out as a racer (having participated in the echelon of F1), De Tomaso rapidly evolved into a business man with an eye for style. He formed his own car company, and was responsible for such hits as the Pantera and the Mangusta, as well as producing a F1 car for Williams. He acquired names and assets from defunct businesses, eventually owning coachbuilding companies such as Vignale and Ghia (later sold to Ford). His holdings extended across automobile and motorcycle boundaries, at one time controlling Innocenti (producing Lambretta scooters and BMC products under license), Maseratti (later sold to Fiat), Moto Guzzi and Benelli. Which brings us to today’s bike, a 1983 Benelli 900 SEI.

1983 Benelli 900 SEI for sale on eBay

Benelli, under the guidance of De Tomaso, was the first motorcycle manufacturer to put a six cylinder bike into production. That was way back in 1973, with the bones of the 750cc machine containing a lot of Honda four cylinder DNA. And while the six banger was never a huge seller – after all it was a bit exotic and very expensive for the time – Benelli continued to refine it and evolve it through the final year, 1989. In between it grew from 750 to 900cc, and gained poise, polish and reliability. Today these are interesting machines from an engineering perspective, but especially from a styling perspective. These are quintessential Italian style and flair.

From the seller:
This is a 1983 Benelli 900 SEI. The vehicle runs great and is mainly used for auto shows.

Superb example of this rare sport bike. Runs great, sounds awesome. Recent full service (receipt for $6300). Updated levers (have originals). Lots of manuals/product documentation regarding the bike is included. Only selling as I now have 6 bikes and need the room.

Today’s example is a 1983 model in 900cc. It has fewer than 12,000 miles on the clocks, and appears to have a fair bit of documentation and various manuals. This is a plus for a brand which no longer exists in the same manner as it did in the past. While Benelli retains an HQ building in Italy, the brand is wholly owned and all bikes are manufactured by the Qianjiang Group in China. Gone are the big sixes, and gone is some of the hand-built exotic nature of these mighty machines. This was truly the pinnacle of classic Benelli, and we are not likely so see the likes of it again. That is what makes today’s bike special. It is available for auction with a starting big of $17,500, and a Buy It Now number of a cool $22k. Those are big numbers, but this bike carries with it some significant history, and intrinsic rarity. Check out all of the details here, and Good Luck!

Featured Listing: 1983 SUZUKI GS750ES

The 1980s: A period of rapid and wild development that set the motorcycling course for the next several decades. It seemed for a time that every innovation was rapidly made defunct by the next quantum leap in engineering – or experimentation. From the end of the 1970s right into the 1990s the world saw massive jumps in suspension tech, chassis engineering, internal combustion enhancements, clutch and transmission improvements, and aerodynamics. Some of the innovations worked and became mainstream. Others were fated to be “one year wonders” as manufacturers rapidly pivoted to something new. In between the extremes some absolutely amazing motorcycles were created. Today’s Feature Listing is one such model: the 1983 Suzuki GS750ES.

Featured Listing: 1983 SUZUKI GS750ES

The Suzuki GS750 first bowed to the world in 1977. At that time it was more of a UJM (Universal Japanese Motorcycle), or what would be better known as a standard motorcycle. This was a response to Honda’s dominant expertise in the inline four game, and at which Suzuki was playing catch up. But catch up they did, steadily evolving the GS750 into an absolute gem of a sport bike; the ’83 ES variant enjoying a 16-valve DOHC head with Suzuki’s trademarked Twin Swirl Combustion Chamber (TSCC), a greatly updated chassis which included the cutting-edge Full Floater single shock setup in the rear, and trick anti-dive forks up front. And rather than the 18/19 inch combo front and rear carried by predecessors, the ES model now carried a 17 incher out back and a GP-inspired 16 inch wheel up front. The smaller front wheel did turn out to be a short-lived fad, but the reduction in rotational weight and gyroscope tendencies helped the smallest and lightest of the GS750 lineage turn and track like no other.

From the seller:
Completely stock, unrestored, unmodified and un-faded
Classic 80’s sport bike style
Two adult owners from new, 3,000 miles believed correct
As close to a showroom-new GS750ES as you’re likely to find
Original tool kits come with bike
Regularly and recently ridden

Price: Mecum Auction Lot F67 April 28 – May 1

Contact: Bob (superhawk65@gmail.com) or visit the Mecum Auction site

The 1983 Suzuki GS750ES was the last of this particular lineup; the economy stalled any further development and unsold units were sold off as 1984 models (unchanged). By 1985 H-D began the Great Tariff War and capacities were dropped to 700cc to avoid additional taxation. That makes this 1983 Suzuki GS750ES the last of its kind, and in about the best shape we’ve seen one of these retro machines. With 70-ish HP on tap and relatively modern components, the GS750ES is a great pick for anyone wanting to pick up some nostalgia – and who also wouldn’t mind riding it around. Suzuki did crank out a large number of the GS750 models (a definite best seller for the Hamamatsu manufacturer), but today few of them survive in this kind of condition.

Today’s Featured Listing will be enjoying the limelight at the Mecum auctions in Las Vegas, April 28 – May 1. With very few miles and sitting in stock, original condition, this bike will certainly catch the eyes of collectors. Interested parties might want to chat with Bob ahead of the auction to learn more. This bike is an incredible time capsule of the pinnacle of the pre-GSXR world, and will certainly be grabbing attention wherever it shows up. Whether you were there and had one, missed out but always wanted one, or just learning about the era now, this 1983 Suzuki GS750ES is worth the effort. Good Luck!!

Desired Duc: 1996 Ducati 900 SS/SP

An affordable way into collecting exotics that you can ride, the Ducati Supersport line is an approachable (and enjoyable) platform on which to begin your journey. Long known for being robust, reliable and a heck of a lot of fun, the Pantah-powered SS models are fairly basic motorcycles that deliver decent performance, great looks and a fantastic soundtrack – without breaking the bank. Today’s example is a 1996 Ducati 900SS SP – the higher spec (and more collectable) of the two seat Supersport models.

1996 Ducati 900 SS/SP for sale on eBay

All Supersports of this era were very, very similar. While introduced with a white frame in 1991, by ’93-’94 all two seater models had a bronze-colored trellis frame, the same 900cc air-cooled, 2-valve Desmo engine with carburetion, a dry clutch and a six speed gearbox. There were a few variations in the line, including full or half fairing, factory carbon bits such as mudguard, adjustable front suspension, aluminum swing arm and wider rear tire. The bikes that had all the options were known as 900SS SP – or Sport Production models – and were affixed with a special headstock plaque indicating such. Think of these as a biposto 900 Superlight, so close are many of the specifications.

From the seller:
Make: Ducati
Model: 900 SS/ SP
Milage: 3562
VIN: ZDM1LC4N4TB021577

For sale is Ducati 900 SS/SP with 3562 miles!!

If not familiar with the SS/SP, some history.
The 1991 Supersports were produced with white chrome molybdenum steel frames and white wheels. The swingarms used needle bearings instead of bushings as in the past. Brakes from the Ducati 851 were used on the Supersport vastly improving braking performance. All new bodywork and a pivoting fuel tank were elegantly shaped.

More from the seller:
The 900 SS/SP (Sport Production) was offered to the North American market only. This model had carbon fiber fenders and clutch cover, sound damping material, adjustable Showa suspension, and an aluminum swingarm.

Displacement: 904.0 ccm
Engine type: V2, Four stroke
Power: 80.0 @ 7000 RPM
Torque: 85.0 Nm @ 6400 RPM
Top Speed 130.5 MPH
Valves per cylinder: 2
Cooling system: Air
Gearbox: 6 Speed
Transmission type final drive: Chain
Dry weight: 410.1 pounds

The bike listed has 3562 miles. Other than a few small issues is in excellent condition (touch up on left mirror, small chip in front fender, paint flaking on left side engine case). bike has been store in a heated room in my collection since purchased. All bodywork and paint is original. No accidents!

Bike will be sold with:
Both sport and regular seat,
Supersport 900 owners manual
(2) keys
Tool kit
Ducati VHS tape

There are few negatives to owning a Supersport. They offer a fair amount of mechanical noise, they vibrate and throb a bit, and the final gearing is very tall making for some interesting clutch work when in traffic. Clutch slave cylinders are usually the first components to fail; replacement is easy and aftermarket options are plentiful. Belt replacement and valve adjustment are probably the biggest deal – the belt change is not difficult on these air cooled motors but the need for shims might make finding a decent Ducati mechanic worthwhile. If you wish to do the work yourself, you will find these are relatively easy bikes to work on. There have been reports of the aluminum swing arm being prone to cracks; this is an area that should be carefully checked.

This very pretty 900SS SP has been housetrained and is looking for a new home. It has some minor mods (Termi cans, the solo tail section, and possibly the brake/clutch lines) but otherwise looks to be stock. It’s nice to see the complete list of what is being offered with the sale, including the original seat. The only real concern I would have is where to find a VHS player to view that Ducati tape! Check out all of the details here, as this is one the Ducati models that will be going up in value in the future. These have been on the cheap side of the market for a long time, but as the well-cared for examples are snapped up, the dwindling stock of good quality bikes will help drive the price curve. Good Luck!!

Long Ranger – 1996 Moto Guzzi Sport 1100

Moto Guzzi advertised the Sport 11oo as the ultimate two cylinder, two valve motorcycling experience, and one could quibble but not truly disagree.  Today’s Goose has some miles, but still looks very good and has a few interesting upgrades.

 

1996 Moto Guzzi Sport 1100 for sale on eBay

Seeming to fit into the general Le Mans form without being so named, the Sport 1100 used Guzzi’s new 1064cc twin with carburetors and electronic ignition.  Power was good at 90 hp, but 70 ft.-lbs. torque at under 6,000 revs made the 5-speed the way to go.  Marzocchi forks were conventional but adjustable, and W-P monoshock supported the shaft drive.  Brakes were the 320mm Brembo offerings, un-linked by popular demand.  Helping the just under 500 lbs. change direction, a 17-inch front wheel was fitted with an 18-inch rear.

Helped by the temperate N.C. weather, this Sport 1100 has the Keihin flat-slide carburetor upgrade, which appears not to use a choke.  Might need to warm up before riding away but the accelerator pump makes for great throttle response.  A carbon Mistral exhaust has replaced the original, and has a no-nonsense sound in the – video – shared by the owner, who also has these comments in the eBay auction:

-I bought this bike in 2012. It has been well maintained and is a blast to ride. – -When I first purchased the bike I sent all the suspension to Cogent Dynamics for maintenance.
-The bike is equipped with Keihin FCR41 carbs.
-The bike runs great and I have never had any issues with it during my ownership it has been a very reliable motorcycle.
-Maintenance has been performed by International motorbikes here in Hickory NC. The owner, Chuck, is a moto guzzi enthusiast and also owns an 1100 sport which he bought new back in the day.
-It is equipped with stainless Mistral exhaust and it sounds fantastic. The bike pulls hard and is a looker.
-I have posted plenty of photos so please look carefully. There is a scratch on the windscreen, you may be able to sand and polish it out or replace it, I just lived with it.
-You will also notice a weld on the exhaust. This repair was there when I bought the bike and it is well done.
-This bike has the impossible to find Heli-bars mounted to the bike. These bars help with wrist fatigue and is a bonus for shorter riders. I can include the original with the sale.

The 1100 turned out to be a winner for Moto Guzzi, and they stayed with it for the new V11 Le Mans in 1998.  Since 2006 though, the company has focused more on the sport cruiser segment, and didn’t import the updated 1200 Sport.  Bids are getting up there but haven’t met the reserve with less than two days to run.  Spring has almost sprung and we’ll be watching !

Bleautiful: 1988 Ducati Paso 750

Welcome to one of the most polarizing models in Ducati history. Perhaps second to only the 749/999 series, the Paso was a little bit like the un-Ducati. With full bodywork resembling more of a a monolithic, monochromatic sport tourer, the Paso took styling in an entirely new direction. Thankfully under the covers the DNA and performance of the F1 Pantah series remained, ensuring lots of lumpy, torquey goodness.

1988 Ducati Paso 750 for sale on eBay

Strip away the Paso’s fully enclosed bodywork (purported to vent away engine heat in a controlled manner) and you would essentially be looking at a Ducati 750 F1 mill with a reversed rear (upright) cylinder head to allow for both barrels to breathe through an automotive-styled carb between the vee. This also simplified the rear exhaust routing somewhat, although the collector is a work of art. The chassis is not quite what you would expect from a company that built round-tube trellis frames for decades, but all covered up in bodywork you would never know the Paso is based on a square tubing cantilever arrangement utilizing the engine as a stressed member. And speaking of bodywork, you may note similarities between the Paso and the Bimota DB1 – after all, they were both the brain child of designer Massimo Tamburini. All in all, the package worked well, yet was a significant departure from the classic lines of pervious Ducatis. The Paso was loved fervently by some, while hated by others.

From the seller:
Excellent example of the Ducati that is credited for saving the brand from disappearing, desinged by Massimo Tamburini, the legend behind Bimota, Ducati and MV Agusta. Paso 750 is powered by 748 cc Desmodue engine, the same Pantah motor from the Ducati 750 F1. Engine starts easy, runs great without overheating or smoking. Originally powered by a Weber carburator which was often the cause of high engine temps especially in traffic, this Paso has been upgraded to a Keihin 39mm flat slide. It currently retains OEM exhaust but an upgrade to an aftermarket system will allow for much better breathing motor.

The heads have been upgraded to M750 which increase the valve adjustment intervals while offering improved valve guides as the originals had a tendency to wear out rather quickly. The cam belts were replaced approximately 3 years ago and the valves were adjusted at the same time. There is around 2600 miles on the oil and filter. All lights and signals as well as the horn work perfect. Even the clock!

The front forks with anti-dive technology were very advanced for their time. Swing arm is lightweight alloy with concentric chain adjuster. This Paso rides on factory original Marvic aluminum wheels, tires have around 3500 miles but still have plenty of thread and perform fine in the canyons.

More from the seller:
Factory blue color is a rare find for a Paso, with some sources claiming only 50 or so were painted in this color. This Paso has been completely refinished by previous owner with correct decals applied and cleared over to prevent them from fading or pealing. Bike looks like new!

Keep in mind this is a 33 year old bike and it will have few quirks and needs. The fuel gauge works but it tends to bounce a bit, especially if the fuel level is at or below half mark. There is a very minor oil leak coming from what appears to be an oil pan gasket. Due to the conversion to Keihin flat slide, the choke has been disconnected.

Sold with a clean California title. Registration is expiring on 3/10/21 and was changed to non-operational to avoid any back fees. The Paso is sold “as is, where is”. In case of shipping, it will be responsibility of the buyer. I will work with the shipper to accomodate their time schedule. Please make arrangements and ask questions before buying.

The Paso offered here is a great combination of updated pricey mechanical components and cosmetic refresh. The motor is a very desireable Pantah mill that is gaining traction with the collectors. It is rare, it is cool and its very fun bike to ride. Overall this motorcycle is an inexpensive entry into vintage Ducati world!

The Paso lineup has yet to see the light of day when it comes to collectors and appreciating values. With 35 years gone since introduction, there are signs that some of that reticence is beginning to change. To find an exceptionally clean and original anything 33 years later makes it more rare than the day it rolled off the showroom floor. And sadly many of these models – after dropping in value – fell into the hands of those who could not (or would not) give them the care and maintenance they deserved.

To be clear, this particular Paso is not strictly a bone-stock example. The seller does a good job outlining the mods made, and the switch from the stock Weber carb is a popular one (Ducati eventually introduced fuel injection in later models), although pictures of the carb throat sans filter make me nervous. The rest of the bike looks used but clean, and readers should note that it has travelled nearly 24,000 miles. Mileage is not an issue with these models provided proper maintenance has been adhered to, but if you are seeking a zero mile bike look elsewhere. There are lots of good photos provided by the seller, so check out all of the details here. On which side of the Paso debate do you fall? Unloved, or unloveable? Let us know in the comments. Good Luck!!

New-ish Old School: 1986 Ducati 750 F1

The Ducati 750 F1 is about as old school cool as you can get. Devoid of any wizardry found on more modern motorcycles, the F1 is a basic bare-knuckle brawler with fancy footwork. To call this a race bike for the street would certainly be accurate, given the underlying DNA came directly from the factory TT1 and TT2 racers. Sporting a similar trellis frame and utilizing a Pantah-era engine punched out to 748cc that were both first utilized in the TT1 racer, the F1 offers a no-nonsense riding experience that is raw and pure.

1986 Ducati 750 F1 for sale on eBay

Both the TT1 and the TT2 racers were effective weapons at such iconic places as the Isle of Man. The F1 followed in those footsteps – such that there were three “special edition” models of the bike named after famous racing circuits such as Montjuich (Spain), Stanta Monica (Italy) and Laguna Seca (United States). With about 70 HP on tap, the F1 was not so much a rocket ship as an adequately fast – but extremely nimble – racing sled. With no anti-lock brakes, no anti-wheelie control, no anti-stall device, no traction control and no quick shifter, this relic is missing everything that helps make racing motorcycles fast today. But what remains is the essence of motorcycling, distilled down to only what needs to be there. Creature comforts? Sorry, not on this bike. If it doesn’t make you faster or the bike lighter, it simply isn’t there. THAT is the beauty of the F1 series, in a nutshell.

From the seller:
Selling one of my 750 F1’s, bike got a new paint job, new belts, overall in great shape. Comes with set of original turn signals and a few more parts. Was last on the street probably 20 years ago when I bought it, see manufacturing date from tires. I had the bike for 3 years and only rode it twice, restored it to what you see and now selling it. Needs new tires and the turn signals which I installed are not connected yet, everything else works and bike starts cold and warm very well. The last 4 pictures show the bike as it looked when I got it, from the original ad when I bought the bike: “Rare 1986 Ducati F1B. Super trap tail pipe, repaired gauge mount, last ridden Donner Pass Hwy 40 hill climb 2000. Fresh oil, new battery, petcock eliminated, runs good. Liquidating collection.”.
More information can also be found at raresportbikesforsale.com when you search for Ducati 750 F1B.
Happy to answer any additional question.

The seller is correct in that we at RSBFS have seen a lot of these F1 machines (and more specialized variants) posted on these pages. In fact, this exact bike graced our pages in its earlier tricolore guise back in 2017. Comments were not kind regarding the butchered paint job, and this seller has done a great job restoring the livery to former glory. Here is a link to find other F1s on RSBFS. Researching older posts offers a great way to learn more about the model, but can also help describe the rough historical value of these models over time. Those serious about a bike such as this F1 would be well advised to do their homework.

This particular example looks pretty good in the pictures. It shows a nicely painted F1 in the standard Italian tricolore scheme. Mileage is low (4,200 claimed), however given that this bike had been raced it is possible that the speedo drive has been disconnected at some point in its life. There appear to be other minor foibles that may need to be sorted here as well. Sharp eyes will also spot some non-stock additions, including modifications to the left-side lowers as well as the tail section. But such is the nature of a 35 year old racer that aspired to be a street bike. There is no claim of “all original, zero miles” here, and the seller has been open about the efforts undertaken to bring this classic back to the status it deserves. Bidders have agreed, with decent traffic and action up to $7,300 at the time of writing. Quite a few watchers are standing by, so expect a lot more bidding once the reserve has been met. Check out all of the details and pics on this auction here. Good Luck!!

Digital Effect – 1999 Ducati 900SS/CR

1999 was the first year for Pierre Terblanche’s re-style of the venerable Supersport, which despite a comprehensive set of upgrades, polarized prospective fans.  This Minne example looks excellent and surprisingly as-delivered.

                  

1999 Ducati 900SS/CR Supersport for sale on eBay

Ducati’s dual-spark 900 was all new, and though the 80 hp was just alright, the spot-on Marelli fuel injection and two plugs per cylinder provided excellent usable power in a wide band.  The charging system was updated, and the air-cooled engine loved the upper-only fairing.  Nicer components with USD Showa forks and adjustable monoshock, and Brembo P4 brakes with four piston calipers.  The gold trellis frame states its case from behind the fairing that, love it or hate it, is designed by one of the best.

Evidently presented by a recovering bike nut, this CR looks excellent with just middling miles at 11,967.  A pair of Giannelli silencers is included, not sure why they were un-mounted.  Two spots of paint damage are shown in detail, but can’t be detected in a wider shot.  The owner posted a cold start – video – and has this to say in the eBay auction:

Amazing original and all stock condition. The bike starts right up with its strong battery, and it pulls strong and clean through the rev range. Shifts are solid and smooth. There are 2 minor cosmetic blemishes that occurred during transport, and the 2 areas are clearing pointed out in 2 of the photos. 1999 introduced fuel injection to the Supersport range of bikes, and this example is the rare half-faired CR model. The bike comes with the set of Giannelli slip-on high mount exhaust that were on the bike when I purchased it. The original exhaust were included in the sale, so I put them on the bike. Bike received full Desmo service 2 years and 1000 miles ago. 4 months ago, a new fuel pump, fuel line and filter installed along with fresh oil and filter.

The new Supersport could’ve been a game changer but the styling changed more minds than the engineering, and the model took the down escalator.  Along the way the powertrain was upped to 800 and 1000cc dual sparks, both also quite rare – but the 900 is a classic Supersport displacement.  No bids yet, but even at the buy-it-now this one will provide the new owner a lot of sport for the money.

Sharp Foreground – 1998 Moto Guzzi V10 Centauro

It’s a good indication when Moto Guzzi applies a “V” to a motorcycle’s model, as all have been classics in their own way.  The V10 Centauro was Guzzi’s muscle bike and this Coachella valley example is beautifully presented by a shop specializing in the brand.

1998 Moto Guzzi V10 Centauro

The Centauro used the Daytona’s four valve 992cc V-twin, and gave it a robust backbone chassis with subframes that supported it front and rear.  Just forward of the air-cooled heads, the cam belt housings are easier seen on the Centauro.  10.5-to-1 compression made 95 hp possible and required an oil cooler in the body color chin scoop.  De rigueur for a Guzzi, power is transmitted by a 5-speed and shaft drive, and WP handles suspension duties.  The bodywork is complex considering there’s not really a fairing, but flows beautifully from headlight to license plate.

Presented by a shop that concentrates on vintage Guzzi’s, this Centauro looks great in black, with grey engine cases and carbon mufflers.  The GT luggage rack / grab handle almost disappears in body color and goes well with the Corbin seat.  Just over 11,000 miles and nice sound in the seller’s – video – which suggests that new tires might be in order.  Comments from the eBay auction:

11K original miles, like new body and frame paint, we just did a tune up and replaced the timing belts.

Current California Non-Op so easy registration.

Great Guzzi for a daily driver, super fast and fun to ride, smooth motor and easy to handle!

Designed by the Marabese design house, Centauro’s have their own owner’s group and were built from 1997-2001, with total production under 2,000 machines.  Reviewers gave everything but the sidestand good marks, though gravity had its usual comment on Guzzi’s hefty build.  Some thought it was Lario’s answer to the Ducati Monster, but with a $20K price tag, even special edition S4’s had a price advantage.  The reserve on this auction should be around half original MSRP, making this Centauro a nice deal for a fan looking for a rare four-valve Goose.
