Featured Listing: NOS 1992 Bimota Tesi 1D

Sept 9 Update: Due to some issues with eBay UK, the seller has relisted this rare Tesi 1D. Links updated. -MI

From the RSBFS International Desk comes this amazing New Old Stock (NOS) 1992 Bimota Tesi 1D. Created as a thesis for his Mechanical Engineering degree, Bimota Designer Pierluigi Marconi’s hub-steering Bimota TESI 1D was first launched in 1990. The bike was an instant sensation with a swing arm arrangement both front and rear, and an evolution of the DB1's all-enveloping bodywork. The Tesi also utilized Ducati motive power. Today's bike is the rare 904 SR version of the 1D, utilizing a factory-stroked Ducati 888 Superbike mill.

1992 Bimota Tesi 1D 904 SR for sale on eBay

The Tesi - like all Bimota designs - was based around a "function first" ideology. The goal of the strange front end was to isolate the braking forces from other suspension work (such as bumps). The end result is a bike that resists nosediving under hard braking, yet can still be compliant over bumps and road irregularities. The target was no different than what Honda attempted with their TRAC anti-dive front fork; the Tesi front swing arm was simply a different way to achieve it. Ultimately, Honda discovered that a conventional fork that was properly calibrated was more ideal than their TRAC trickery - and Bimota eventually came to the same conclusion. But today, the Tesi continues to conjure evocative imagery and remains a super-exclusive rarity by collector standards.

To find this NEW example (the term "museum quality" loses all luster when compared to this specimen) in this rare configuration available is unheard of - and unlikely to happen again. Coming out of a museum located in Germany, I'll let the seller pick up the tale on this rare find:

From the seller:
This 1992 Bimota Tesi is one of a handfull of bikes left from our collection which we have been dissolving this past year due to continued health related reasons which in turn require us to consolidate all our personal items and to scale back from multiple locations to just one.

Being able to own an original, genuine, brand new, never used Bimota Tesi 1D has got to be special for most serious collectors ; it being a 904SR, the rarest of all 412 Tesi versions ever build should make it an even more desirable and unique affair.

More from the seller:
New motorcycle, never ridden, never run, properly prepared for longterm display. Specifically ordered from the distributor without any fluids when new in 1992. Neither the hydraulic brake system front and rear, nor the cooling system nor the original battery have ever been filled with fluids. All mechanical components inside the engine are most likely still coated with assembly lube from the Ducati factory. The engine is filled with a light-weight oil to preserve internals, it has never been started or run. The 904SR was Bimotas first special version, build in only 20 units and based on the Ducati 888 engine, but with a longer stroke to come up to 904cc. It was the most powerful of all Tesi's in unrestricted tune and several of these 904's were used by very wealthy enthusiasts in racing series in Europe during the 90-ies

More from the seller:
This Bimota Tesi was kept in a climate controlled environment without UV light present, so there has been no deterioration of any rubber pieces and no discoloration of any painted or coated surfaces. Of course there is no oxidation present on any metal surfaces or fasteners. The protective yellow zinc plating on all
3 cast iron Brembo rotor surfaces is still present, the seat foam on the molded solo seat pad and backrest is still uncompressed. The tires mounted were specified to be racing tires when ordered new. Levers, grips, pegs, chain, sprockets as most everything else on this motorcycle are as new as they were in 1992.

More from the seller:
This Bimota comes with all the original ownership documents, the owners manual, the warranty booklet, copies of the parts manual and workshop manual and the original Tesi toolkit in duplicate. The original early Tesi rear stand, the one off custom front stand (for displaying the bike with both tires off the ground) both mph and km/h dash boards (km dash & computer packed up, mph dash with protective white film still underneath mounted in fairing) and two original Weber Marelli P7 ECU computers, one chip'd for regular street use and the other fully open P7 ECU chip'd for race use performance, are also included. Multiple other original spares come with the bike. Of course the red Bimota cover is present and in its correct Bimota bag, but has never been used.

More from the seller:
There are absolutely no guidelines as to what the value of this motorcycle might be in the current international market place. The Bimota Tesi was unique and different when it came onto the market in the early 1990-ies. With only 412 Tesi 1D (all street versions, across all production years, all displacements sans racing bikes and prototypes) build during the 1990-ies it is today probably one of the rarest collectible bikes anyone could own from that or any other period. It was the epitome of italian engineering at the time

Riding a Tesi is said to be far more conventional that it would appear; other than a relatively horrid turning radius, one cannot tell that there is anything different once underway. But I doubt this would be the bike to use to learn of that experience. A motorcycle can only be new once. It can only have zero miles once. If you are in the business of collecting, you look for the very best example you can find. When it comes to a 1D model Tesi, this absolutely has to be the most stunning, original bike we have ever seen. Values are so difficult to ascertain because we very rarely have real sales data for bikes in this condition. The seller has thrown out a rather large number as a starting point, but is open to considered counter offers. There are also a ton of pictures and even more detail on the auction page. Check out this perfect Tesi 1D here; you will not see another like it again. Good Luck!!

Super Rare Italian Beauty: 1991 Bimota Tesi 1D!

For Sale: 1991 Bimota Tesi 1D

Update 10.17.2011: Just a few hours remaining to snag this one. Current bid is $15,200 and looks like reserve has been met. Good luck!

Today's RSBFS Featured Listing is a very rare, and very special bike. Any Tesi will quickly draw the stares of motorcycle enthusiasts, but how about a Tesi 1D prepped by the Bimota factory as a backup bike for AHMRA Battle of the Twins (BOTT) events with rider Dale Quarterly and *hand signed* by none other than Pierluigi Marconi himself?

From the seller:
This is a 1991 Bimota Tesi 1Dsr. It is the most advanced and celebrated bike of the time, being part of a limited series of thirty bikes produced by Bimota of Italy for sale in the US. The information I recieved from the previous owner was that this particular bike was modified for racing by the factory in an attempt to bolster their design theories. It is one of two bikes that was hand assembled and signed by Pierluigi Marconi in 1991 for Bimota's short and unsuccessful attempt at racing in the US. It was to be campaigned by Dale Quarterly in the Battle of the Twins series put on by AHMRA, which was a hot and competitive event during the time. Shortly after, Quarterly quit the effort in disgust when the bike and team could not be made competitive. The bike you see here was the back up bike for those events though it was never raced in anger.

The engine started out as a V-Twin, four valve head, water-cooled, belt driven cams, Ducati 851 that was bored to 906cc's. It has Twin Raymond Roche injectors along with other internal modifications. The stock suspension has been replaced with Ohlins units front and rear. The radiator fan has been removed and along with other items, but other then the stock bodywork, this is how the bike was to be raced. When new in 1991, in it's stock form, the out the door price was $42,000.00! There are about 4500 miles on the bike. The first speedometer expired with 3600 miles showing and the new replacement has about 815 miles on it at this time. A sister bike to this one is today in the Barber Museum in Birmingham, Alabama, though it has been extensively modified.

Created as a thesis for his Mechanical Engineering degree, Designer Pierluigi Marconi’s hub-steering Bimota TESI 1D first hit an unsuspecting world in 1990. The bike was an instant sensation with a swingarm arrangement both front and rear, and an evolution of the DB1's all-enveloping bodywork. Bimota was headed into the future, and with the Tesi 1D they were looking to get there ahead of everybody else!

Stare at this tidy shot of the front suspension for a while. After a bit, you might ask why other manufacturers did not embrace this particular concept. After all, the swingarm front suspension does a nifty job of isolation braking forces and minimizing chassis pitch changes, allowing the suspension to handle bumps in the road. Load paths are fed directly into the chassis and not via spindly tubes like a conventional fork. Stiction is greatly reduced as well. Weighty components are all kept down low, helping lower the overall center of gravity. What's not to like?

As Bimota found out, there are some minor drawbacks to the hub-center approach. First off, there is a severe limit to how far the front wheel can turn, and most bikes similar to this Tesi have terrible turning radii. The removal of the front wheel can be a very involved process, and adjustment of the tie rods and various control arms is critical - making this design more difficult for the average user/wrencher. Ah, but Bimota has always made concessions in favor of the Gods of Speed and Design, as many Bimota owners already know. Quirks and minor maintenance issues come with the territory.

From the seller:
1991 Bimota Tesi 1 D.

Owned since 2005.... Had 750 Miles when I got it. Only 875 miles now showing, not sure if original.

Mileage update: Bike has a just under 4500 miles on it. 3600 orig Speedo that died plus 835, now.

Looks great, Runs strong. Original Paint. New battery , yesterday. Tach seems to be only going up to 2000 RPM . Charging and other electrics seem to be ok. Tach dead on my 92 model, so may be a common ailment. Tags expired in 2007 and has Cali PNO, so no penalties. Bike always stored indoors , and run every couple of months to keep healthy.

Have very large bike collection being thinned down to make more space. See pictures. Numerous pictures to show the good and the bad of it. Overall, a pretty well preserved bike.

The seller, noted So Cal collector Chris Dolan, has offered many pictures and details regarding this particular bike. Some minor scratched are noted and highlighted in the pictures. In addition to the photos and text, there are also a few videos of the bike in question. These are worth watching if only to hear the beautiful sound of that healthy Ducati Desmoquattro!

This auction started out with a $5,000 opening and an $18k BIN. Since that time bidding has begun in earnest and the BIN has been dropped. This bike was purchased at auction in 2005 for $22k according to the text in the ad, so it will be interesting to see where it all ends up. With so few 1D machines in existence - plus the documented factory race team history - this is one Bimota that you don't want to miss. Isn't this why you read RSBFS every day? Be sure and check it out here, and good luck!

Brand new 2008 Bimota 3D Carbonio down under

Brand new 0 miles 2008 Bimota 3D Carbonio for sale in Australia.

I guess we have to stop calling these "rare" as this is the 4th Bimota Tesi 3D that we have listed in a month! Thanks to our reader Leigh for pointing us to this brand new Tesi 3D Carbonio that will be auctioned off in Australia:

This is a "regular" production (as opposed to the limited edition first production series) Tesi 3D in all black "carbonio" or naked carbon colour (if it's 'naked' would it still be called a colour?).  I have written extensively about the Tesi 3D before, so you can read all about it by checking out previous Tesi 3D listings.

There is no additional info provided on this specific Tesi 3D other than model year and mileage, but if you are interested, I would suggest getting in touch with the auction house to find out how to place a bid.  Click HERE to jump to the listing.

Apocalypse now! Bimota Tesi 3D LE (#23 of 29) for sale w/876 miles!

2008 Bimota Tesi 3D Limited Edition - #23 of 29 - w/876 miles for sale with a bargain Buy It Now price of $25,000!

What the heck is going on?  This is the 3rd Bimota Tesi 3D that we've listed (not counting serial #00 listed back in July) for sale in the span of less than a month!  First it was LE #06, then it was #28, and now it's #23 - the world must be coming to an end!

Up for sale is a Bimota Tesi 3D Limited Edition number 23 of 29 produced worldwide.

This bike was carefully broken in and is fully sorted. The 600 mile service was performed by Ken Zeller of Evoluzione Cyclesports. This bike is completely stock and in "as new" condition, no disappointments. Retail price was over $40K.

From the Bimota website:

Bimota have now sold the 29 limited edition version of last years Tesi 3D. In 2008 Bimota are offering a more "standard" version of the Tesi 3D. There is no such thing as a standard Bimota, but the new Tesi 3D will cost 3,000 Euro less featuring less carbon fibre and Bimota's own CNC machined brake and clutch levers. Bimota themselves think these are just as good as the Accossato items on the pricier limited edition. The fluid reservoirs are now standard items rather than CNC machined units. The powertrain is the Ducati air-cooled 1100cc L-twin. Choose between an all blacked out carbon version or the white and red. All at around 26,000 Euro.

This bike is one of the more desirable Limited Editions with the extra carbon fiber, CNC reservoirs and wet clutch.

The bike is located in Thousand Oaks, California.

Regular readers of RSBFS will need no further introduction to the Tesi 3D, but to those untrained in the art of hub center steering, here's a very brief intro to why there's a swingarm hanging out in front instead of a pair of telescopic forks: regular forks are inherently flawed in their design in that they have to handle braking, suspension, and steering forces all at the same time, resulting in issues such as fork compression (and hence reduced suspension travel) during braking, causing a change in steering geometry and affecting stability of the bike during cornering.

Hub center steering designs separates braking, suspension, and steering functions, all but eliminating brake dive (or front suspension compression) and geometry change during braking, allowing the front suspension to remain "active" during braking and cornering, greatly increasing stability.

The Tesi 3D is the 3rd hub center steered bike from Bimota (after the 1990 Tesi 1D and the 2004 Tesi 2D), with the punchy Ducati air-cooled 1100DS engine pushing a welterweight 370 lb. It won't trouble any supersports on the track, but in the real world riding on the roads, it should be plenty fast enough. Here's a previous article on The Kneeslider on the Tesi 3D with some great pics.

So all that technical info sounds great, but what's it like to ride?  Two words: confidence inspiring.  But don't take my word for it - read what these magazine guys have to say about the handling of the Tesi 3D: Cycle World, Motorcycle.com, and Motociclismo.

Now we've addressed the technical / logical side of things - but what about the emotion side?  We all know that purchasing a motorcycle is as much a technical exercise as it is an emotional one, and the Italians - and more specifically Bimota - are the absolute masters at pushing the right buttons - just look at that CNC machined "omega" frame; the machined billet reservoirs sitting oh so pretty on top of the triple clamps; the carbon fiber tie roads and bodywork; even the saddle is exquisitely finished with the words "Tesi 3D" embossed on it. You could park the Tesi 3D in your living room, pour yourself a glass of red wine, and sit there and admire it all day - it's that much of an eye candy.

Just to get your pulse running, here's a great video of a Tesi 3D being flogged around the Tsukuba circuit in Japan:

And here's a Tesi 3D race bike being started (note the roar of those open Zard exhaust @ 0:48):

With the world coming to an end sometime in 2012 according to the Mayan calender, I would not walk, !

Can you tell it’s Friday? 2008 Bimota Tesi 3D Limited Edition #28 of 29!

Bimota Friday is BACK!  And to kick it off we have a 2008 Bimota Tesi 3D Limited Edition - #28 of 29 - with only 60 miles (what?!) on it!

Up for sale is a MINT condition, pretty much brand new,Bimota Tesi3 D Limited Edition number 28 of 29 ever produced. This bikes retail price is over 36K...and good luck finding one of these Limited Edition models for sale...let alone...finding one with only 60 miles on it.  The Bike is located in California.  The buyer is responsible for handling all shipping!

It's not everyday that you come across a Bimota, and even rarer still if it's a Tesi.  Just check out that fabulous engineering on that hub center steered front end.

A quick bit of info on the Tesi: before working for the exclusive Italian marque, ex-Bimota chief engineer Pier Luigi Marconi wrote his Mechanical Engineering degree thesis on the hub-center steering concept.  While at Bimota, Marconi applied his thesis design to create the Tesi 1D (‘Tesi’ meaning ‘Thesis’ in Italian, and ‘D’ indicating that it has a Ducati engine - a Bimota modified 851 motor – inside) – Bimota’s first alternative front end design.

After the Tesi 1D was introduced in 1990, there came the Tesi 1D SR (slightly larger engine displacement than the 1D), the Tesi 1D EF (Edition Final), Tesi 2D, and now the latest incarnation, the Tesi 3D.

The Limited Edition refers to the very first production series of the 3D, the it has carbon tie rods, CNC machined fluid reservoirs on top of the triple clamp, and a wet clutch, as opposed to steel tie rods, plastic fluid reservoirs, and a dry clutch for the later production series.  I am not so sure about the seller's claim of "29 ever produced" as some other countries - such as Japan - also had a limited edition first production series as well.

Personally, I would say the LE is definitely the best looking of all the 3Ds, especially with the machined fluid reservoirs sitting oh-so-pretty on top of the triple clamps (which coincidentally echo the same design on the 1986 Bimota DB1).  The starting bid of $30,000 - while significantly cheaper than MSRP - is still a bit high considering that another similar Tesi 3D LE sold for quite a bit less earlier. Click here to see other Bimota Tesis previously listed.

In any case, the Tesi 3D is definitely the jewel in the current Bimota lineup (yes, more so than the DB7 in my opinion), so if you are lucky enough to be in the market for one, I'd say go for it.  Besides, how many Bimota Tesi 3Ds have you seen lately?  😉

2008 Bimota Tesi 3D serial #0000 – first one in the US!

2008 Bimota Tesi 3D - serial #0000 - with only 1040 miles!

Another post, another Bimota, and another one of my favourites from the marque.  Can you tell I like Bimotas?  And this one is the very special hub center steered Tesi 3D:

If you searched for this brand of motorcycle, you already know what you are looking at.  Unquestionably one of the most exotic and rare motorcycles on the planet.  Owning this bike was a dream for me since the first time I saw one but unfortunately financial circumstances force the sale of my baby. Rather than retype all the manufacturer details, please visit the following bimota website:

http://www.bimotaamerica.com/bikes_t3da.html

2008 Bimota Tesi 3D with 1040 original miles.  This motorcycle is sure to gather a crowd wherever you take her.  Incredibly gorgeous in person and so much detail that you can literally stare at it for hours and find something you never noticed before.  An engineering and machining marvel with a forkless front suspension, trellis rear swingarm, omega aluminum frame, and carbon fiber bodywork.  This bike is powered by a very reliable Ducati 1100cc engine.  This bike has a very comfortable riding position and a great power to weight ratio due to it's light weight.

Another intersting aspect of this particular bike is that the VIN number ends in 000000 meaning it is the first Tesi 3D to hit american shores. This bike was also the actual bike photographed and tested at Miller Motorsports Park by one of the mainstream US motorcycle magazines.  This bike was purchased from an authorized Bimota dealer on an MSO.  I am the first owner.  Clear title in hand and ready to go.

The motorcycle does have a couple of minor flaws that were there when I originally purchased her.  I have attempted to capture these issues in the posted pictures.  The issues are not significant and could be corrected by the new owner.  They were never enough to bother me and were never noticed by anyone of the hundreds of people who have stopped to galk at this bike. These flaws consist of:

- chipped clearcoat in rear fender (clearcoat only, carbon fiber is unaffected)

- chipped/cracked clearcoat area on front fender (again clearcoat only, carbon fiber unaffected)

- small indendations in aluminum rear section of right side of swingarm and scratches in trellis (touched up so very difficult to see) presumably from an inproperly place swing arm stand by the "professionals" at the magazine that tested this bike

- minor dings in upper fairing where hand controls bump into fairing at full lock.  This is a design flaw and cannot be adjusted out of one side.  The marks were present when I bought the bike and I was able to adjust one side to clear but the other cannot and be in a functional position.

Retail on this bike is $36,900.  My reserve is far less than that.  Own this dream bike at a fraction of the original purchase price.  Please feel free to ask questions

The mainstream US motorcycle magazine is none other than Cycle World (Feb 2008 issue) and they did test this bike at Miller Park.  The first production batch (I think 29 for the US market) had a wet clutch, carbon fiber tie rods and CNC machined brake and clutch reservoirs on top of the triples, as opposed a dry clutch, steel tie rods and plastic reservoirs on the later production units.

If you're wondering how that front end works, check out the video of one of Motocorse (Japan importer of Bimota and makers of exquisitely fine motorcycle components) test riders flogging a the 3D round the the Tsukuba circuit:

Watching the 3D overtake slower bikes on the OUTSIDE gives me goosebumps!!  Oh, .
