Featured Listing – 1981 Bimota KB2 Laser !

Update 2.10.2022: This bike has SOLD! Congratulations to buyer and seller! -dc

Like its then-young designers and builders, the Bimota KB2 could delay worries of certification and conformance and focus on its chosen goals – such as 500 TT competition.  Duncan at Garage Assassins presents a very rare and special KB2.

1981 Bimota KB2 for sale asking $25,500

One look at the trellis frame surrounding Kawasaki’s 550 cc engine will let you know it’s designed for sports.  It cradles the air cooled mill from the sides, allowing easy access to the carbs and cams, and builds up to support the beefy headstock from below.  Ceriani forks have the axle centered in the fork leg.  Nor any compromises at the back of the chassis, with the drive sprocket just behind the swingarm pivot, so there’s no change in chain tension with suspension travel.  Thanks to bespoke headers and 33mm Mikuni slides, power is increased to 65 hp from the GPz550.  Wheel sizes are a racer’s 16-inch, likewise the full fairing which encloses the 4-into-1 collector.  Tank and seat fairings streamline low, with cutouts in the tank for fuel shutoff.

Having completed some preparation, Duncan from Garage Assassins has this KB2 on consignment at their suburban Seattle shop.  Pictures show the exotic details and techniques that made Bimota’s reputation.  Duncan shares these notes on the KB2:

1981 Bimota KB2 7,946 original km.
VIN# KB8200014 One of 177 units built.
Unrestored example of this special 1981 Bimota KB2, yes 7,946 original kms.
Serious buyers only please. $25,500.00 US funds.

This has been part of a private collection for over 20 years, properly stored and maintained.  Said to be Massimo Tamburinis personal favorite of Bimota designs before he departed for Cagiva,  This 1981 Bimota KB2 Laser is the marriage of a super stiff, hand built Italian frame and a Kawasaki  GPZ550 powerplant. Just 177 of these were built. Factory gold Campagnolo Magnesium wheels in 16 inch. Brembo brakes, Marzocchi forks, the bike is light and nimble, very comfortable seating position, feels very short and compact.

Bimota started as a boutique company that outsourced engine-building to Japan to concentrate on bleeding-edge, flex-free frames. No expense was spared on parts, and as a result these bikes went for a hefty $12k in their day. Other factory mods include M1R Marzocchi forks and Brembo four pot calipers.

All the KB models had Kawasaki powerplants, the model signifying the second with Kawasaki power. Its factory rating was around 65 horsepower, but you should get a decent bit more with the upgraded pistons, camshaft and carburetor. At only 375 pounds dry, this one was said to smoke the 60 pound heavier donor Kawis in the twisties. You can see the upgraded Mikuni flat carb peeking out behind the bodywork here. This bike has been in a proper Man Cave stored dry, No Fuel in it. We have recently gone through carburetion, fresh fluids changed in motor/gear box. Complete chassis nut/bolt, body work off for inspection and set up. This bike is ready for a new owner to ride or put on display. It starts immediately, makes beautiful noise. All original, nothing weird, completely correct. Never raced,
never down, never abused. This bike is ready, to be safe we would recommend new tires as these are old, not cracked but old and hard.

Would that Bimota have been able to stay young and continue shipping chassis kits, perhaps the partnership would’ve continued longer, and racing success might not have been so intermittent.  The company grew and made cycles based on all major Japanese models, then began a great success with Ducati drivetrains, and even tried their own engines.  Models like the Tesi reinforced their leading edge designs and manufacturing chops.  But early on the stripped-down sportbikes let the chassis design shine, like this KB2.

Innovative – 1983 Bimota KB2 Laser S

One of the final Tamburini designs before he departed for Cagiva, the 2nd Kawasaki-powered Bimota delivers the company paradigm of chassis design and lighter weight using state-of-the-art powerplants.  Perhaps named for the laser the chassis fabricator wished he had when assembling the 44 frame members, which cradle the 543cc air-cooled Kawasaki inline four.  Because the engine is relatively narrow, the red frame holds both sides of the motor and allows the swingarm to pivot at the chain drive sprocket, keeping chain tension constant despite suspension movement.  Another innovation is the use of 16 inch wheels front and rear, reducing gyroscopic forces and turning in a little easier.

Originally introduced with a 500cc engine, the “S” has the 550, delivering 65hp at 10,500 rpm.  A wet clutch is in the engine cases, and drives a 6-speed transmission.  Big 280mm disk brakes in front, with 210mm disk at the rear.  40mm front forks and rear monoshock are adjustable for preload and damping.  The full fairing is punctuated by small air openings and rounded edges, and uses flush fasteners.  Very neat cockpit has Brembo clip-ons and a full-featured instrument cluster courtesy of Kawasaki.

Seeming un-restored and very nice shape, this KB2 shows only a couple of nicks in the seat fairing.  Bimotas of any age are very rare, but the Kawasaki driveline can be comforting.  This example resides in England but is offered by a eBay dealer from Italy.

From the eBay auction:

Said to be Massimo Tamburinis personal favourite Bimota design and not without good reason with an excellent power to weight ratio and build quality second to none, due to its very high cost when new Bimota only managed to build and sell 177 of them so they very rarely reach the market this being the first we’ve ever seen in the shop, it’s an excellent un restored example with just under 14000 recorded KM’s believed to be genuine having had the same owner for the past 21 years.

This KB2 is a very neat design, very innovative, only 8,000 miles, appearing quite clean and original.  More of a TT than an envelope-pushing superbike, a rideable exotic ready for a look…

Laser Focus: 1982 Bimota Laser TT KB2

For Sale: 1982 Bimota Laser TT KB2

There are those that claim the NR750 oval piston Honda is the holy grail of collectable sportbikes. Still others point to Ducati superbikes (D16RR and 750SS, new and old), rare gray-market import bikes (insert two stroke of dreams here) or one-off manufacturers who have since come and gone from the scene (Britton, perhaps?). Whatever the stuff of your dreams, these early Bimotas must surely be near the top of the list.

The concept behind Bimota is simple: provide the customer with the finest, flex-free frame that engineering can design, bolt up the best components that money can buy, wrap it in hand-laid fiberglass that only an Italian designer could create, and stuff it full of reliable, Japanese power. And if this sounds like a recipe for a parts bike / kit bike experience, that is exactly how Bimota started life. Customers were shipped frame kits, suspension components and bodywork, the customer then supplied a donor bike from which to pilfer engine/trans/running gear, and then the customer put it all together.

This kit bike concept allowed Bimota to enter the motorcycle market without the pressures of becoming a full-fledged manufacturer. It also means that all early Bimotas such as this KB2 are hand-built and as indivudual as the customers who built them. This adds to the mystique, the rarity, and ultimately the desireability of these bikes. It certainly helped that any Bimota would flat out smoke contemporary Japanese hardware of the day – despite using the same powerplant. The level of handling was on another plane entirely.

From the seller:
Up for auction is a 1982 Bimota KB2 Laser TT. This is a very clean unrestored original motorcycle that I am selling for my Dad who is selling his collection.

The Vin# is 00134. The odometer shows 1,473 Kilometers (915 Miles).

The condition of the bike is fantastic and My dad is the second owner

For those readers who don’t know what a KB2, is, allow me to educate. The second major series of Bimotas to be powered by a Kawasaki engine (K=Kawasaki, B=Bimota, 2=Series of KB bikes), the Laser accepted the engine and running gear from a Kawasaki GPz550. Thus, the KB2 is one of the smallest bikes created by the Rimini firm. It is difficult to obtain accurate numbers, but production quantities for the KB2 were relatively small (some sources indicate only 177 units total). And while these bikes do come up for auction occasionally, it is a pretty rare occurrence – and pricey to boot.

This bike looks to be in exceptional condition, absolutely clean and without obvious damage. The listed mileage is low (less than 1,000 miles), although you cannot always trust the odometer in this case as this was one of the pieces pilfered from the donor bike when the kit was assembled. If you are serious about the bike, best to contact the seller and confirm.

A KB2 in average condition is a $15,000 purchase any day of the week. Exemplary bikes, like the one pictured here, are much more into the $20,000 territory. This auction started at .99 (!), and is currently sitting around $4k with reserve not yet met. For your opportunity to own this gem – or just to drool over more of the pictures as provided by the seller – . And while you’re at it, tell ’em you found it on RSBFS!
