The acronyms of the two-wheeledThe lexicon of all motorcyclists

this feature applies braking force to both wheels when the rider uses the brake lever (front) or the brake pedal (rear). The Electronically Linked Braking System (ELB) offers greater responsiveness and more balanced braking at front and rear. The system offers more interconnection when the rider applies harder braking, and reduces or eliminates interconnection for light, low-speed braking.

when interconnected, if you operate only the front brake lever, the system also applies an amount of braking to the rear. If you only depress the brake pedal, the system will also apply a quantity of braking to the left front caliper. The interconnected Electronic Braking System is cornering enhanced (C-ELB) and takes into account the angle of inclination of the motorcycle, or lateral acceleration on a Trike model. C-ELB modifies the distribution of braking pressure between the front and rear brakes when braking in corners, to improve the bike's ability to maintain the rider's intended trajectory.

The cornering-optimized traction control system (C-TCS) prevents excessive rear-wheel spin during acceleration, whether traveling in a straight line or around a curve, particularly on low-grip surfaces such as wet or unpaved roads. It boosts rider confidence by adapting to changes in traction and cornering angle. Offering two modes—Standard for dry surfaces and Rain for wet surfaces—it has been standard equipment on Harley-Davidson LiveWire™ and CVO™ models since 2020. It has also been available as an option on most touring models since that same year.

Honda's Combined Brake System (CBS) is a combined braking system designed to improve stability and safety by automatically distributing braking force between the front and rear wheels.

Unlike conventional systems where each brake operates independently, the CBS activates both brakes simultaneously when a single lever or pedal is operated. Honda offers two types of CBS. The first, called Dual Combined Brakes (DCB), is primarily intended for large-displacement sport bikes. When the front brake is applied via the right-hand lever, part of the braking force is transferred to the rear, and vice versa. This technology provides more stable deceleration and limits changes in vehicle behavior, particularly at high speeds. The second type, known simply as the combination brake, is mainly found on scooters and small motorcycles, simplifying braking, particularly in urban environments.

This system is suitable for a wide range of drivers, from beginners to the most experienced. By optimizing the distribution of braking force, CBS on Honda motorcycles improves vehicle stability and reduces the risk of wheel lock-up, particularly on slippery surfaces such as rain or gravel. What's more, it helps reduce braking distances, enhancing rider and passenger safety. Last but not least, by limiting uneven tire wear, CBS helps extend tire life.

CNC (Computer Numerical Control) technology plays a key role in the motorcycle industry by enabling the production of custom parts with extreme precision. Using pre-programmed software, the “numerically controlled machine tool” controls the movement to produce components that fit perfectly, both for aesthetic and functional reasons.

Motorcycles can be equipped with CNC-machined parts. This process ensures a better fit for riders’ needs, offering unique parts that are lighter, stronger, and optimized for performance. Whether for improving style, comfort, or aerodynamics, CNC machining opens up vast possibilities for customizing and optimizing motorcycles.

Yamaha's D-Mode allows riders to choose from several engine maps, optimizing performance according to riding conditions. This technology enhances the motorcycle's versatility, adapting equally well to urban riding and demanding terrain. Yamaha's D-Mode includes several riding modes, some of which are customizable depending on the motorcycle model.

Drive Mode often works in conjunction with other electronic assistance systems, such as traction control (TCS) and ABS, for a safer and more optimized ride. Some Yamaha models also allow for even more fine-tuned settings, providing precise control over throttle response and power delivery.

Among its benefits, D-Mode improves safety by reducing the risk of loss of traction and provides riding comfort through instant adaptation to conditions. It can also influence fuel consumption, allowing for more economical riding depending on the mode selected.

BMW Dynamic Chassis Adaption allows the semi-active chassis to offer two different riding positions.

The first features a flat steering angle, which optimizes riding stability thanks to optimized chassis geometry.
The second riding position offers a firmer damping setting, a higher spring rate, and a higher ride height. Raising the rear more than the front results in a steeper ride height, a lower steering angle, and reduced trail, making the motorcycle easier to steer and handle.

In addition, DCA incorporates all the features already known from DSA: spring rate adjustment, automatic load compensation, and two customizable damping modes.

inspired by the automotive world, the gearbox is in fact made up of two half-boxes (and therefore two clutches), each handling a different ratio: one for even gears, the other for odd gears. This means that when one gear is engaged, the gears directly below and above it are already engaged in the other half. When a gear is shifted, all that remains is for the two clutches to work in reverse. With the gears already pre-engaged, shifting is quick and easy, with no jerking or loss of revs.

The Ducati Data Analyzer (DDA) is an advanced tool designed to thoroughly analyze the performance of a Ducati on the track, catering to both motorcycle enthusiasts and professional riders. It collects a wide range of data to help optimize the bike’s settings and improve overall performance.

Among its key features, the DDA records and compares lap times, helping riders track their progress and identify areas for improvement. It also captures split times at strategic points on the track, providing a detailed analysis of critical sections. The tool provides speed data, measuring maximum and average speeds to better understand performance on different sections of the track. It also analyzes acceleration and braking to evaluate the effectiveness of maneuvers. Finally, it incorporates data on track conditions, such as temperature and humidity, providing essential context to refine the analysis.

The DDA allows drivers to download and analyze their data on a PC via a high-speed USB port, offering a detailed graphical visualization of performance.

The Ducati Data Analyzer (DDA) collects and analyzes essential data to evaluate the performance of a Ducati motorcycle on the track. The DDA+ GPS takes this concept even further by integrating a GPS module—a satellite-based positioning system—that allows it to record the precise racing line on the track.

With this feature, riders can view their racing lines, compare different trajectories, and analyze how their choices affect overall performance. The GPS thus adds a geospatial dimension, providing a more comprehensive analysis of riding style and track lines for those who want to maximize their potential.

BMW's Dynamic Damping Control (DDC) is a suspension management system for motorcycles that automatically adjusts the stiffness of the shock absorbers based on riding conditions and riding style. It offers several riding modes, such as “Comfort,” “Normal,” and “Sport,” allowing riders to customize their experience.

DDC works in coordination with other safety systems, such as ABS and DTC traction control, to ensure synchronized operation. Using sensors, it reacts in real time to changes in terrain, thereby improving safety and control. Unlike its predecessor, the ESA II, the DDC uses dynamic mapping to optimize shock absorber settings, offering precise and customizable adjustments.

While riding, the DDC continuously analyzes data and adapts damping based on riding maneuvers—such as acceleration, braking, or cornering—ensuring greater stability and enhanced comfort. This system enhances driving dynamics and contributes to the joy of riding, offering an enriched experience on two wheels.

DES (Ducati Electronic Suspension) is an electronic suspension system developed by Ducati that operates using sensors and advanced electronic control. DES adjusts damping and preload settings in real time to optimize comfort, stability, and performance. Various preset configurations are available, allowing riders to customize the settings to their preferences.

The benefits of DES:

• Automatic adjustment: adjusts the suspension based on the selected riding mode (Sport, Touring, Urban, etc.).
• Improved handling: optimizes the suspension to enhance traction and stability, particularly when cornering and braking.
• Enhanced comfort: effectively absorbs road irregularities, reducing the impacts felt by the rider.

DES also complements models equipped with the Skyhook system (DSS Evo), which further refines dynamic suspension control.

Diamond Like Carbon" coating is a chemical surface treatment to create an amorphous carbon coating with properties close to natural diamond. This gives the fork tubes their characteristic glossy black color.

DLC protects against scratches and stone chips. The fork glides much better, without "sticking", which improves suspension sensitivity and comfort. Much harder than hardened steel or hard chrome, DLC also has the advantage of being inert, non-oxidizing and highly resistant to acids and salts.

The Ducati Multimedia System (DMS) is an advanced connectivity system that allows you to connect a smartphone, a Ducati GPS, and Bluetooth headphones for a more intuitive and immersive riding experience. With this technology, the rider can make and receive calls, listen to music, and follow GPS directions directly from the motorcycle’s TFT screen.

The system integrates with the handlebar controls, allowing riders to easily manage features without taking their hands offthe handlebars, thereby enhancing safety and riding comfort, even on long trips. Compatible with several Ducati models—from the Panigale to the Multistrada and the Diavel—the DMS ensures seamless and intuitive connectivity, transforming the riding experience into a connected and optimized interaction.

DOHC (Double Overhead Camshaft), or DACT (Double Overhead Camshaft), is a valve train system used in most engines. It is characterized by the presence of two overhead camshafts, one dedicated to the intake valves and the other to the exhaust valves.

This design allows for better control of valve timing, promoting improved gas flow, more efficient combustion, and higher engine speeds. DOHC is often paired with a four-valve-per-cylinder configuration, optimizing engine efficiency and power.

This system is widely used on sport bikes, roadsters, and high-end models from brands such as Ducati, Honda, Yamaha, Kawasaki, and Suzuki, where engine performance and responsiveness are essential.

Ducati Power Launch (DPL) is a standing-start assist system designed to optimize acceleration by electronically regulating engine power and controlling the torque delivered to the rear wheel. This system limits excessive wheel spin and prevents the front wheel from lifting too abruptly, ensuring a fast and controlled start, allowing the rider to focus solely on releasing the clutch.

The DPL typically offers several levels of intervention, allowing the rider to adjust the assistance based on traction conditions and riding style. It is particularly useful on sport bikes and high-performance models, where it improves the consistency and effectiveness of race starts.

The Ducati Quick Shift (DQS) is an electronic shifter that allows the rider to shift up or down without using the clutch or closing the throttle. Inspired by technologies used in racing, it speeds up gear changes, thereby optimizing acceleration and improving riding comfort by reducing the rider’s effort.

This system has been standard on most Ducati models since 2011, delivering a more dynamic and high-performance riding experience on both the road and the track.

Daytime Running Lights (DRL) are LED lights designed to improve the visibility of motorcycles during the day, thereby enhancing rider safety. They can replace the requirement to turn on low beams, which is mandatory for all motorized two-wheelers. However, because they are not bright enough, they are not suitable for use at night.

The Ducati Riding Mode (DRM) is a riding mode selection system that allows you to adapt the motorcycle’s behavior to road conditions and the rider’s preferences. Ducati offers several modes, such as "Sport," "Touring," "Rain," and "Race," each of which automatically adjusts key settings such as traction control (DTC), ABS, and throttle response. Riders can also customize these settings using various levels of intervention, providing an optimized riding experience whether for daily use, sport riding, or track riding.

Introduced with the Panigale V4, Ducati Slide Control (DSC) is an electronic riding aid developed in collaboration with Ducati Corse to control rear-wheel slide during acceleration out of corners.

Using Bosch’s six-axis inertial measurement unit (6D IMU), the system calculates the motorcycle’s side-slip angle in real time. As soon as the side slip exceeds the level set by the rider, the control unit instantly reduces engine torque by adjusting the Ride-by-Wire throttle opening, ignition timing, and fuel cut-off. Unlike traction control (DTC), which manages wheel spin along the wheel’s axis, DSC specifically manages lateral slippage. It thus allows for spectacular yet controlled drifts, without the risk of sudden loss of traction or a highside. Adjustable to two levels (Level 1 prioritizes pure performance with more pronounced slippage), this system allows you to optimize exit speed with complete confidence.

The Ducati Skyhook Suspension (DSS) is a semi-active suspension system designed to stabilize the motorcycle's ride height regardless of road conditions. Its name refers to the “celestial hook” theory, an engineering concept that imagines the chassis suspended from a fixed point in the sky in order to remain perfectly still.

To bring this idea to life, the system uses several acceleration sensors mounted on the suspended (frame) and unsuspended (wheels) components, combined with data from the inertial measurement unit (IMU) and braking or acceleration inputs. By continuously monitoring these parameters, the control unit adjusts the compression and rebound damping of the Sachs components in a matter of milliseconds via electronic valves. The DSS thus significantly reduces nose dive during braking and wheelie during acceleration, improving comfort and stability.

Available in the DSS EVO version on the Multistrada lineup, the system also adjusts preload and automatically adapts to the selected Riding Modes (Sport, Touring, Urban, Enduro), while allowing riders to adjust the load (rider alone, with a passenger, or with luggage) to provide an optimal balance between sporty performance and long-distance comfort.

Dynamic Traction Control (DTC) is an advanced traction control system from BMW that electronically adjusts the vehicle’s power output to optimize traction and stability. It reduces wheel spin on low-grip surfaces (steep terrain, mud, snow, etc.), while allowing a certain degree of drift for a more sporty driving experience. Unlike a conventional traction control system, it balances performance and safety by maintaining active traction control, even in demanding conditions.

Ducati Traction Control (DTC) is an electronic traction control system designed to optimize traction during acceleration while preventing loss of rear-wheel grip.

Originally developed in Superbike racing and later introduced as standard equipment on the 1098 R, the system has evolved significantly thanks to the integration of six-axis inertial measurement units (IMUs). In its modern versions (DTC EVO), the control unit does more than simply compare the rotational speeds of the front and rear wheels: it also takes into account the motorcycle’s lean angle, roll, and drift dynamics. Using predictive algorithms, the DTC continuously assesses the permissible level of wheel slip based on the rider’s selected setting (typically adjustable across 8 levels). As soon as critical slippage is detected, the system adjusts engine torque by first regulating throttle valve opening via Ride-by-Wire, then adjusting ignition timing and cutting off fuel injection. This precise control prevents sudden jolts, ensuring smooth acceleration and maximum stability when exiting a turn.

Now standard across the entire lineup (Panigale, Streetfighter, Multistrada, Monster), DTC allows riders to safely harness the engine’s full potential, both on the track and on the road.

Dual-CBS is an advanced evolution of the Combined Brake System (CBS) developed by Honda to optimize braking performance while improving the motorcycle's control and stability. Unlike a conventional braking system, Dual-CBS—as a “combined” or linked braking system—applies the front and rear brakes simultaneously, regardless of which control is used.

One of its main advantages is its ability to stabilize the motorcycle during braking. When the rear brake is applied, braking force is also applied to the front, but in a gradual and controlled manner, thereby limiting nose-dive and improving the motorcycle’s grip on the road. In addition, the risk of wheel lockup is significantly reduced thanks to optimized brake force distribution and ABS intervention when necessary.

First introduced on the Honda CBR1000F in 1993, Dual-CBS was designed to maximize safety by delaying wheel lockup, which preserves vehicle control and significantly reduces stopping distances. By providing better stability and a smoother braking feel, this system not only improves safety but also enhances the riding experience.

The Ducati Vehicle Observer (DVO) is a predictive algorithm developed by Ducati Corse, derived directly from MotoGP and Superbike racing prototypes.

Unlike conventional electronic aids, which react only after detecting a slide or wheelie, the DVO models the motorcycle’s overall dynamics in real time. By combining data from the inertial measurement unit (IMU) and dozens of sensors, this virtual twin estimates physical quantities that cannot be measured directly, such as the vertical forces acting on the tires, the actual level of traction, or the maximum torque tolerated by the chassis.

This high-precision data feeds control systems—such as traction control (DTC), wheelie control (DWC), and launch control (DPL)—enabling them to intervene proactively. Instead of abruptly correcting a drift, the electronics continuously refine their response thresholds, ensuring optimal acceleration and predictable handling. First introduced on the Panigale V4 before being adopted by the Streetfighter and Multistrada lineups, DVO pushes the boundaries of riding performance.

Ducati Wheelie Control (DWC) is an electronic system designed to manage and control wheelies in order to optimize acceleration while ensuring the motorcycle’s stability and safety. It uses the IMU (inertial measurement unit) to analyze changes in lean angle and the rate at which the front wheel lifts in real time. If the lean angle exceeds a preset threshold, the system adjusts engine torque and power delivery to maintain optimal balance. Some models also factor in the lean angle in their calculations, allowing for more precise adaptation based on riding conditions.
