Master’s Thesis: 1992 Bimota Tesi for Sale

Throughout the history of the motorcycle, there have been many attempts to develop a superior suspension system, and the hub-center steered Tesi or "Thesis" was Bimota's attempt to radically alter the sportbike landscape and do something completely new, a shocking move for such a tiny company. The ubiquitous telescopic forks have a number of disadvantages, chief among them geometry changes caused by "dive" under braking: the fork tubes compress, steepening the steering. This can theoretically be used to your advantage, but the "stiction" or friction between the sets of sliding tubes certainly can't. But so far, telescopic forks have proved the best compromise and engineers clearly understand their limits, so they persist as the most common way to suspend the front end of a motorcycle.

The only manufacturer to really buck that trend recently, at least in significant volume, has been BMW. But their Telelever front end is being used less and less, owing to a different concern: radiator placement, since the front "A-arm" of the Telelever system takes up the space where one would normally reside. Bimota got around this issue by using an "Omega" frame that allowed the front swingarm pivot to be very low to the ground,  so a pair of radiators could sit easily above. The frame gets its name from the two Ω-shaped machined aluminum side plates that sandwich Ducati's liquid-cooled v-twin. Originally a stock 851 motor, it was eventually stroked to 904cc after the first batch of bikes was built.

Unfortunately, the Tesi's steering linkage was complicated and expensive to produce, and any improper adjustment or slop in those joints caused steering feel to suffer, something that seems to be an issue with alternative front ends in general. BMW's Telelever front is famously stable on the brakes, but has often been criticized for a lack of front-end feel, although a set of Öhlins shocks at both ends supposedly improves things. The Tesi had the same reputation: it was wild and exotic, and test riders could brake deeply into corners with confidence, but the bike lacked a bit of feel, even when everything was working as designed. Which took some doing, given the relatively complex system connecting the clip-on bars to the front wheel.

The other issue with the Tesi is a bit more theoretical: a swingarm front end should be much easier on front tires than a bike with a telescopic fork , allowing the Tesi to run a much softer compound tire without experiencing the same wear. But manufacturers design their tires to work with telescopic forks, so one hypothetical advantage is lost there as well, unless systems like this become more common.

But the biggest issue with the Tesi was its high cost: for practical purposes, it was just a Ducati 851 with cool bodywork. All that engineering had very little impact on performance, making it more of a stylish statement of intent than an actual improvement. The Tesi name is very apt: the original bike literally was a graduate thesis project, and was built around a Kawasaki GPz 550 engine. Bimota's prototype was built around a V4 Honda, but that proved to be too wide, so the production model went to the narrow and powerful Ducati v-twin.

From the original eBay listing: 1992 Bimota Tesi for Sale

We had hoped to hold onto this gem for a few more years and wait until the worldwide Bimota market has improved and collectors and enthusiasts alike have come to realize how rare and exceptional some of these bikes and specifically the Tesi really is. Sadly health related problems and financial issues force us to take this step now and sell his rare and unusual motorcycle, hopefully to a likeminded enthusiast.

So there is no misunderstanding, please be so kind to have your finances in order and be able to pay for this motorcycle when the auction is finished, however high or low the final value amount may be. An immediate $500 deposit is expected from the winning bidder upon winning this auction, the remaining outstanding amount due upon pickup or prior to leaving our possession no later than 14 days from end of auction. Please prepare for this request by having your paypal account balance reflect the needed amount beforehand and be ready to complete purchase of the bike in a timely manner. Thanks so much for understanding.....

There will be a flat fee charged to have this motorcycle crated professionally and shipped fully insured to any location, worldwide. Of course: If you prefer to pick this motorcycle up in person, or have it picked up by any professional service or freight forwarder of your choice at our location here in Basel, in Switzerland, the entire packing and shipping fee will be waved.

Please look at the shipping details for more information. All else is explained in the description below in detail.

NOS motorcycle, never ridden, never run and properly prepared for long term storage on a pedestal when new in 1992. Specifically ordered and delivered from the factory in this condition. Original in every way as it was in 1992.

Pictured with and without bodywork mounted to show that the exceptional condition throughout is not just skin-deep.

All 3 cast iron Brembo rotors still have the yellow zink plating on the rotor-surfaces to protect the rotors from oxidation while sitting. This coating wears off on the first mile ridden and when the first contact of the rotor with the brake pads occurs.

Hydraulic system, cooling system and the original battery have never been filled with any fluids. The engine is filled with a light oil to preserve internals, seals and bearings. This motorcycle was kept in a climate controlled environment without UV light exposure its entire life, so there has been no deterioration of any rubber pieces nor any age related discoloration of any other parts

This Bimota comes with the original owners manual, warranty booklet, copies of the parts manual and workshop manual and 2 sets of the complete and original Tesi 1D toolkit. This Tesi also comes with both the mph dashboard and the km/h dashboard, both were ordered with the bike in 1992. The original early Bimota Tesi rear stand is also included with the bike

Please only bid if you are serious in your intent to purchase this motorcycle at the end of the 7 day bidding period. Obviously any taxes or duties the buyer has to pay upon importing this vehicle into the country of their choice is solely the responsibility of said buyer

This motorcycle is over 25 years old and hence is fully legal to import into most countries including the USA (EPA and DOT excemptions apply to vehicles over 25 years of age) as of last year!

The bike is currently located in Switzerland, but I'd guess anyone buying this is looking to collect and display, not actually ride this Tesi: it's a museum-piece, but what a museum-piece! Happily, the seller has provided plenty of pics of the bike for us to drool over, since most of us won't be owning or riding one of these anytime soon: less than 200 of the 1D model seen here were built before the updated SR version was introduced. Even better, the bike is shown sans the fully-enclosed fairing that really only allows hints of the weirdness within to peek out, something rectified on the minimalist styling of the current bike.

Bitcoin level Bimota: Zero miles 1992 Bimota Tesi 1D in Switzerland

Here is a time capsule, a zero miles/NOS Bimota Tesi 1D SR that has never had fluids installed.  The 1st generation Bimota Tesi is already a bit of unobtanium and something every collector considers so this one is certainly one to take notice of...plus the color scheme is perfect for the holidays.

1992 Bimota Tesi 1D with zero miles in Switzerland

Thinking back on the late 1990's, it seems safe to say that the manufacturer that best embodied the period ethos of "throw-it-against-the-wall-and-see-what-sticks" was Bimota.   Part of that was due to its small nature/lack of multi-layered governance and part of it was also probably due to it being an Italian firm where a certain level of fla.ir is expected.  Regardless, Bimota was willing to bring unproven concepts all the way to market and while some of these never delivered as promised (cough-VDue-cough), the Tesi series actually did what it promised.

The Tesi promise was improved handling via a new suspension feature; hub-centered steering.  The Bimota hub centered suspension setup transferred braking force into the frame, not up into the headstock area like on a conventional bike.  Without the impact of braking on the forks, the front end was significantly more stable which made handling feather quick and rock stable.

NOTE:  A good write up about the concept of hub-centered steering and Tesi can be found here.

>

At the launch of the Tesi 1D Bimota said the plan was to build 300 but the actual production numbers are a bit vague.   According to sources I found, over 400 were produced between its launch and end in 1994 and this number is said to have included about 50 produced with 400cc for Japan as well as some "Final Edition" and SR models which came with a 904cc 851 motor (the seller indicates this is one of the SR editions).

Mounted in Bimota's beautiful "Omega" frame the 904cc Ducati powerplant worked with the hub-center handling improvements to deliver a bike incredibly nimble for its size.  So why didn't the the Tesi and it's hub-centered design become the future of motorcycling?  The main factor was probably price.  When introduced the Tesi was offered at the eye-popping price of $40,000 USD which made it the most expensive motorcycle on the market.   Also, the complexity of the bike scared away some owners, especially after reports surfaced that the futuristic electrics and digital dash board could suddenly shut down or give wrong readings.

>

Now lets look at this particular Tesi 1D.  According to the seller, the bike has essentially been a display piece since production.  Below is a summary of what the seller has to say:

  • Never ridden, never run, properly prepared for long term 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 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.
  • 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 three 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.
  • Comes with all the original ownership documents, customs forms, 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 the fairing) and two original Weber Marelli P7 ECU computers, one chip'd for regular street use and the other fully open P7 ECU chipped for race use performance, are also included.
  • Multiple other original spares come with this bike. Of course the red Bimota cover is present and in its correct Bimota bag.

Note:  The seller also provides additional photos via an online photo album here.

Now for the real question - is this bike worth the current asking price of $150,000 USD?   Yes, you read that number right - $150,000 USD.   That's almost 4 times the original asking price which is a level of increase I don't think we have ever seen on RSBFS before.  To be honest, when I saw that asking price I thought this was possibly a test listing by the seller but after communication with them, this is in fact the actual Buy-It-Now asking price.  Since in most cases sellers expect offers with 10-15% of the BIN price, its seems safe to say this one is going to cost 6 figures US for any interested parties.

So is a zero miles 1D SR Tesi worth that much?  Personally I don't think so but the 1D and 2D series of the Tesi come up for sale so rarely I don't know what the current value is.   I do think the current ask price means it won't go to an investment oriented collector but it could draw interest from the zero miles/"crate-bike" crowd.   I guess we can only wait and see...but it would sure be a nice way to start the new year with it in your living room.

Collectable Thesis: 1992 Bimota Tesi 1D

For Sale: 1992 Bimota Tesi 1D

The weather forecast for St. Louis, MO is 59 degrees F with no chance of rain. Why is this important? Simply because in that fine city, with reasonable riding weather even on the last day of the year, there sits a Bimota Tesi 1D with only 350 miles on it - just waiting for its next care taker. The question is, will that next owner be a collector or a rider?

We have posted bikes from this particular seller before, and should I ever make it east of the Rockies I will make a point to drop by in person and oogle the well-presented machinery. As we see in the pictures - and as vouched for by RSBFS readers in the know - this dealer of high-end collectable motorcycles is the real deal. And in this case, the collectable in question is one of the iconic models in Bimota's history: the swingarm front suspension Tesi.

There have been several Tesi 1D models on the market lately. Most recently CA collector Chris Dolan placed two up for auction. You can see them HERE and HERE. Both bikes were looking to fetch north of $20k, and I would expect something similar with this particular example, if not higher.

From the seller:
1991 Bimota Tesi
Super nice
everything works
Mint condition
owners manual toolkit and workshop manual included.

350 original miles.
Nice!

With only 350 miles on the clock would you be willing to ride this beauty? I know that the common thinking is with mileage so low this is probably a bike someone will park rather than risk adding miles to. I really admire that kind of restraint, as I don't think I would ever have that kind of control.

This auction is live right now and the bidding has started at a moderate pace. From the opening ask of $500, this bike has risen to just under $4k - which is far, far below the going rate. There is a reserve in place as well, so it will be interesting to see if bidding will reach that mark. For more information and pictures, click the link and jump over to the auction. Don't forget to tell us what you think about this one!

Who Needs Forks? 1992 Bimota Tesi 1D

Who Needs Forks?  1992 Bimota Tesi 1D

Well, here is another one for the engineering geeks in all of us.  If you've followed RSBFS for a little while you may have noticed Tesi's appear for sale on a  regular basis.  Kind of surprising for such a limited production run bike.  One other thing I've noticed is they rarely are for sale from private parties.  I'm not saying there is a conspiracy, just kind of strange.

Now this little lady is for sale from a private seller.  The auction states, " Only 375 miles showing, not sure if original".  That statement along with other auctions I've seen from the seller makes me believe these are bikes that are being bought at auction and resold.  From seeing enough Bimota listing I know Bimota owners know every last mile on their bikes.  There is nothing wrong with buying an auctioned bike but I think they should be advertised as so.  I would venture to guess a bike being auctioned  may not be as nicely cared for as most.  They could just be turning bikes as well but I do not believe they are from a private collection.

This Tesi has a sick tach/speedo unit (it does not register past 2000rpm) and is apparently missing a radiator fan.  Hmmmmmm.  Are early Tesi's known for electrical woes?

The stock Marzoochi suspension front and rear has been replaced with Ohlins units.  Nice upgrade.  I have my doubts about the mileage on this bike but it sure does look low mile from the lack of grime underneath.  Maybe I'm wrong.

Yuck, what is that?  It's on both sides.  Is it melted rubber from someones boots?

The paint sure looks to be in low mile condition.

The seat doesn't look to be in low mile condition.  The  seller says it is from a kitty;  the kind with claws.

If you want a Tesi, this is why you want it.  The sellers' last Tesi sold for just over $20,000 and was a similar bike.  For that kind of coin I think I'd ask a few more questions about the bikes history.  I'm really torn on the condition of the bike.  In some photos it looks mint and then in others it looks so, so and then the electrical bugs make me wonder.  What do you guys think?  Be sure to check out the auction as the seller does have a couple of videos posted of the bike.

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!

Funny Front End? 1995 Bimota Tesi 1Dsr

For Sale: 1995 Bimota Tesi 1Dsr

Nobody has consistently astounded the motorcycle world quite like Bimota. The small boutique builder based in Rimini, Italy continues to impress with a flair for artful style and technical innovation. This is as true today as it was back in 1991, when the first Tesi 1D was introduced to the world. Today's bike, a stunning 1995 Tesi 1D-SR model, looks as radical today as it did back then.

The original Tesi 1D was powered by a Ducati 851 engine - a watershed powerplant from Ducati, with desmoquattro four valve heads, fuel injection and liquid cooling. The Tesi 1D-SR was powered by a 904cc evolution of that motor; the bigger bore creating even more motive power and torque. Am I the only one that sees a little Ducati Paso in that bodywork?

From the seller:
Up for auction is a 1995 Bimota Tesi 1D SR. This is a very clean motorcycle that I am selling for my Dad who is selling his collection. My dad is the second owner. The bike has 115 miles on the odometer. This was a special order through the Bimota distributor and only 2 were ordered this way. It has the latest chasis but the older body style. The condition of the bike is fantastic and it does come with a free and clear title.

With hub center steering, digital instrumentation, top-shelf Brembo stoppers, fantastic enclosed bodywork, trick composite three-spoke wheels, proven Ducati v-twin power, and the exclusivity of a limited production work of art, the Bimota Tesi 1D-SR is a true collector target.

This particular bike has travelled only 115 miles in its pampered lifetime. The seller claims this is a custom order direct from Bimota, one of only two models with this frame/engine bodywork combination. I don't know how to verify this (perhaps some of you RSBFS Bimota experts can chime in here), but the VIN number supplied ends in a very, very low 002.

This bike comes from the same unbelievable collection that brought us the KB2, DB1, DB4, as well as assorted rare and desireable Ducatis (green frame 750ss, 750 Sport, 900ss). Most have been very low mile bikes, some no miles at all. This one has travelled enough that you know it works, but not so much for it to incur damage and wear.

As for pricing, these bikes are rare enough to make an estimate difficult at best. It is immaculate, desireable, exclusive and titled. The auction is currently in the $10k range, with reserve not met. This one will definitely eclipse the $20k mark before it is done, but it remains to be seen how high the reserve is set. To check out more pictures of this amazing motorcycle, click the link and . Good Luck!
