2009 Bimota DB7
DB7 – Distinctly Bimota
The DB7 is staged to add new definition the 1000cc Super bike category. The objective in the development of Bimota’s newest Superbike was to create a motorcycle that is light and powerful with superior road manners, while remaining distinctly Bimota in style and attitude. Furthermore, the new Bimota was to be as capable on the track as it is on the street.
With so many Superbike manufacturers, there are also many advanced and extremely capable motorcycles. So for Bimota, simply being fast and race inspired is not enough, a Bimota must offer something more, much more.
The DB7 looks like no other Superbike, never to be mistaken for another brand. With the team colours of red, white and black applied to the carbon fiber body shaped by the pen and hands of designer Enrico Borghesan, the Bimota family DNA is clear to see. This Superbike dares true motorcyclists to get close and indulge in its details. The beauty and drama of the DB7 at a distance is surpassed only by its detail. Each and every assembly, fastener and chassis component is elegantly fashioned and manufactured with care using advanced materials. From billet machined sub-frames, footrests and control levers to the structural carbon fiber tail section and titanium silencer, no compromise was ever considered nor made. The details are simply spectacular.
Light, powerful and only the best
Whether used for road or track, a sport bike’s lightweight represents a big advantage and the DB7 leads the way. The rear section of the bike is crafted from structural carbon fiber, eliminating the need for a sub-frame. The weight-saving advantage of carbon fiber is also exploited for all fairing sections, fenders, chain guards and instrument supports. Further savings come from the titanium silencer, new ultra-light Bimota wheels plus machined aluminium frame plates, controls and chain adjusters. The DB7’s road manners are inspiring and confident thanks to the choice of superior materials, suspension, brakes, frame, wheels and controls. Utilizing the best components from development partners such as Brembo, Marzocchi and ExtremeTech, combined with Bimota’s own ultra-light wheels and frame, thrilling and track-proven performance is ensured.
Bimota chose to power the DB7 with the spectacular World Superbike dominating Ducati Testastretta Evoluzione engine. Ducati, a partner of Bimota from the beginning, has developed the Testastretta into the world’s most powerful production twincylinder, while retaining all the advantages of the L-Twin configuration. It’s a perfect match to the Bimota formula and guarantees excitement with every twist of the throttle.
Handcrafted sport motorcycles are the only thing that Bimota creates, and they are its singular motivation. The DB7 is the manifestation of the pride, dreams and talent of Bimota.
The 1098 Testastretta engine
The Testastretta Evoluzione engine is the pinnacle of Ducati’s development and perfection of the L-Twin engine. World Superbike dominance for the last 15 years is the result of their continual commitment to twin-cylinder technology and the 1098 Testastretta Evoluzione, the most powerful twin-cylinder production engine in history, is a fitting reward to the continued ingenuity of their engineers.
Highly ‘over-square’, the 1098 sports a massive 104mm bore and a short 64.7mm stroke. To optimise the benefits of the new big twin, the completely redesigned cylinder-heads are combined with advanced MotoGP induction technology to produce an incredible 160hp of pure excitement.
The 1098 cylinder-heads feature a reduced angle between intake and exhaust valves, allowing highly efficient, straight intake ducts to feed newly shaped combustion
chambers through large valves (42mm inlet, 34mm exhaust), operated by radical camshafts.
The potential of the new cylinder-heads has been optimised by feeding them with MotoGP developed elliptical throttle bodies. With a 30% increase in air flow over conventional throttle bodies, the new elliptical shape contributes significantly to the power of the DB7.
Impressively, the 1098 is one of the lightest Ducati Superbike engines ever, thanks to the close scrutiny of every component including transmission gears and gear selector drum as well as the oil pump and primary gears.
The DB7 1098 benefits from additional Bimota enhancements including a new fuel injection system has been developed for the DB7 employing Magneti Marelli 12 hole micro fine spray injectors, controlled by an advanced Walbro ECU (engine control unit). The Walbro system is highly flexible in its tuning capacity, a great advantage during development and for racing applications, plus it enjoys the simplicity of diagnostics using a standard windows based PC.
Finally, the 1098 is complemented by a Bimota designed exhaust system. Exhaust header pipes are formed of 52mm stainless steel and route to a catalytic converter mounted under the engine. The exhaust then exits to an efficient right side mounted titanium silencer. Of course, the DB7 responsibly complies with the strict Euro3 emission standards.
The DB7 frame is the most advanced evolution of the Bimota hybrid-trellis design. The composite structure employs mitred and welded thin wall CrMo4 (Chrome Moly) tubing and machined 6082 AC 100 Aluminium Alloy. The classic round tubes of the original trellis design have been replaced for the DB7 with oval section tubes, in a 50mm x 30mm dimension with 1.5mm wall thickness. The trellis section joins the new larger more robust alloy plates, and these work in harmony with the engine as a ‘stressed member’ of the frame group. The result is a substantial 2.3kg reduction in weight, yet with torsionally increased rigidity. What you feel as a rider is confident and consistent road holding and stability.
The new DB7 swingarm is constructed with the same oval tubing and machined aluminium of the frame. With the swingarm pivoting directly in the engine cases and using an advanced GP style rising rate linkage system, rear wheel travel is highly responsive and accurately follows even the most demanding road surfaces. An important feature of the system is the ability to adjust ride height, independent of spring pre-load and other suspension settings, via an eccentric top shock mount. This is a critical feature when perfecting suspension set-up.
Structural carbon fiber
The tail section of the DB7 is crafted in structural carbon fiber, an advanced material and methodology widely used in the aircraft industry. Its use contributes significantly to the DB7’s lightweight and simplicity of form. This superior technical solution eliminates the need for a separate rear sub-frame, and effectively lowers the center of gravity of the bike.
The DB7’s Marzocchi Corse RAC 43 forks are secured with machined aluminium crowns, the lower crown using triple screws. The cartridge type forks, feature nitrite coated sliders for smooth consistent action, and are fully adjustable. Rebound damping offers 32 clicks of adjustment and compression offers 13, with further adjustment for spring preload that is easily accessible externally at the top of each fork. Additionally, each fork leg features an exclusive Bimota machined aluminium caliper mount. With 120mm of precision controlled wheel travel, road holding is accurate and confident both on the track at maximum speed and spirited sport rides on the road.
Rear wheel travel is controlled by the outstanding ExtremeTech 2v4 shock. Specifically developed for the DB7, it is constructed of fully machined aluminium and features separate high and low speed damping adjustments, for both compression and rebound, plus spring preload. As a result, the 2v4 can be accurately tuned for any riding style or track condition.
Monobloc brake calipers
For a motorcycle with the performance of the DB7, superior stopping power is fundamental, so the new Superbike mounts only the best; Brembo Monobloc racing calipers. The M4-34 calipers are machined from a solid block of alloy and the result is a single piece unit that has much higher rigidity and resistance to distortion, for maximum stopping power during extreme braking. Combined with 320mm discs, world championship level braking performance is in the hands of every DB7 rider. Super light-weight wheels
Fitting lighter wheels has always been the racer’s way to improve the handling and track ‘feel’ of a race bike. This normally expensive upgrade, is standard fare for the DB7. Designed in-house and manufactured exclusively for Bimota, the new ten spoke wheels are ultra-light and dramatically reduce the critical moment-of-inertia, contributing greatly to the DB7’s braking performance and ease of direction change. Brake and clutch controls
The DB7 controls follow the quality and performance priority of the entire bike. Bimota has selected the race specification Brembo ‘radial’ pumps for both front brake and clutch actuation. Moreover, the billet machined levers, a Bimota exclusive, offer a wide range of ‘reach’ adjustability, ensuring comfort and control for every rider.
Premium carbon fiber
Look closely at any World Superbike or MotoGP racebike, and you’ll find an all carbon fiber fairing, fenders and tail section, so of course you’ll find the same on the DB7. The aggressive GP inspired body design is finished in the Bimota team colours of red and white over black carbon fiber, and at a glance, the DB7 seems to be in motion even when at rest. In addition, the Bimota sports carbon fiber instrument mounts, chain guards, licence plate bracket, and when combined with the structural carbon fiber rear tail section, titanium exhaust silencer and the billet aluminium used throughout, it’s clear why the sleek and aerodynamic DB7 feels so light and confident on the track.
Ease of use, daytime visibility and accuracy are the fundamental elements of the best instrumentation, and the DB7 delivers just that. A big analogue rev counter, paired to a large LCD screen with multiple digital readouts are essential in design and perfectly placed for quick access to information while underway. The various functions available are retrieved using the two input buttons which are designed for use even with gloved hands.
In addition to the expected displays of time, distance, water temperature and time for service, the DB7 offers further race oriented features. An ‘over-rev’ indicator lamp, also called a ‘shift-light’, is positioned next to the rev-counter and illuminates to warn the rider that maximum rpm has been reached. The instrumentation also offers complete timing and recording of racetrack performance. Actuated by the starter button, up to 20 laps can be recorded and reviewed after your track session. Recorded information includes time elapsed, maximum rpm, and maximum speed achieved for each lap.
Powerful twin vertical poly-ellipsoid projection headlights show the way, while the bright LED turn signals and taillight let the rest of the world know your intentions

At the heart of the new Bimota DB7 is the Ducati 1098 Testastretta Evoluzione engine. Powerful, and light, it makes the kind of power that excites the heart with each twist of the throttle, yet its linear power delivery allows entering and exiting the turns fast a confidently controlled experience.
The DB7 introduces a new hybrid oval tube trellis frame that utilizes lightweight machined plates in its design. The same engineering solution is used in the unique rear swingarm for a package that not only delivers rigidity and predictable handing, but also lends a harmonized technical look to the bike.
The innovative rear suspension links the swingarm directly to the engine and employs an advanced Extreme Tech rear shock developed in cooperation with Bimota. The fully adjustable shock attaches to the SPB (Bimota progressive system) progressive linkage system, for maximum control and traction in the corners. The rear suspension is offset to the right side, allowing space for the rear cylinder exhaust system.
Upper and lower fork crowns are billet machined and mount fully adjustable Marzocchi Corse forks with 43 mm sliders with DLC (diamond like coating) treatment for smooth and predictable reaction to the tarmac.
Wheels, Brakes and Body
The alloy forged wheels are built specifically for Bimota design and are some of the lightest most torsionally rigid produced in the world. The powerful front brakes utilize twin 320 mm discs and radially mounted Brembo four pad four piston callipers. On the back a floating 230mm disc matches to a Brembo 2 piston calliper.
The top fairing is formed of structural carbon fiber and supports the instruments and headlamp, eliminating the need for a separate subframe. The rear tail section is also made of structural carbon fiber and also benefits from the same elimination of a separate subframe. Combined they significantly reduce the overall weight of the bike.
The digital instrument panel combines analog and digital readouts. The unit records 20 lap times, and top speed each lap.
The narrow fuel tank, with a capacity of 26 liters, has been sculpted to be extremely thin between the legs and matches perfectly the seat to maximise rider control and comfort. With a seat height of only 800mm, riders of all heights can enjoy the performance of the DB7.
Combine all of the DB7 innovations and you have a bike that weighs-in at an incredible class leading 170 kgs.
The DB7 bristles with fine CNC machined details including the rear frame plates, engine mounts foot rests, rear swingarm sections, chain adjuster plates and both clutch and front brake levers.
The new DB7 charms the heart by combining characteristic Bimota style cues with uncompromised attention to details and unparalleled fit and finish.
