Ducati filed a revolutionary electric motorcycle patent in April 2026 that focuses on solving one of the most persistent challenges in electric motorcycle design: excessive width caused by motor and battery packaging. The patent centers on an innovative sensor relocation strategy that allows the electric motor to remain exceptionally narrow while maintaining the precise torque control and performance characteristics that define the Italian manufacturer's riding dynamics.
Revolutionary Sensor Positioning Technology
The core innovation in Ducati's patent involves relocating the motor position sensor from its conventional location on the motor shaft to a gearbox shaft within the transmission system. Electric motors typically rely on position sensors to determine the exact location of the rotor at any given moment, which enables precise torque delivery and efficiency through field-oriented control algorithms. Traditionally, this sensor mounts directly on the motor shaft for maximum accuracy, but this configuration adds significant width to the motor assembly.
Ducati's solution calculates rotor position indirectly by reading sensor data from a downstream gearbox shaft and applying known gear ratios to determine the actual motor position. While this introduces potential inaccuracies from gear lash and mechanical tolerances, the brand appears confident in compensating through advanced software algorithms and precision engineering. This trade-off delivers substantial packaging benefits, allowing the motor housing to remain compact and the overall bike profile to stay slim.
High-Performance Drivetrain Architecture
The patent reveals a transversely mounted electric motor capable of spinning at approximately 18,500 rpm, paired with a multi-stage gear reduction system that delivers power to the rear wheel via a conventional chain final drive. This configuration deliberately mimics traditional internal combustion motorcycle architecture rather than pursuing radical EV-specific layouts. The motor produces maximum power and torque figures comparable to Ducati's MotoE race bike, the V21L, which generates 110 kW (150 hp) and 140 Nm of torque.
| Specification | Ducati Patent Details | Ducati V21L MotoE (Reference) |
|---|---|---|
| Motor Speed | 18,500 rpm maximum | 18,000 rpm maximum |
| Power Output | Estimated 110+ kW | 110 kW (150 hp) |
| Torque | High-performance range | 140 Nm |
| Final Drive | Chain transmission | Chain transmission |
| Voltage Architecture | High-voltage system | 800V system |
Vertical Transmission Stacking Strategy
Beyond sensor relocation, the patent describes a gearbox design that stacks gears across multiple planes rather than spreading them horizontally. This vertical stacking approach builds the transmission taller instead of wider, maintaining the narrow profile essential for motorcycle lean angle and rider ergonomics. Electric motorcycles commonly suffer from excessive width due to battery packs and motor assemblies, which compromises cornering clearance and the natural riding feel that performance motorcycles demand.
The multi-stage gear reduction system allows efficient power management while preserving smooth and controllable delivery characteristics. By maintaining a geared transmission rather than adopting direct-drive or hub motor configurations, Ducati preserves the mechanical feel and responsiveness familiar to riders of conventional sportbikes.
MotoE Racing Heritage Integration
Ducati's patent development directly builds upon knowledge gained from its MotoE World Championship participation, where the company has served as sole supplier since the 2023 season. The V21L race prototype weighs just 225 kg-12 kg below the minimum weight requirements imposed by Dorna and FIM-and achieved top speeds of 275 km/h at circuits like Mugello. The race bike's battery pack contains 1,152 cylindrical 21700-format cells providing 18 kWh capacity at 800V system voltage.
Production of the 23 V21L units for the 2023 MotoE season began in December 2022, with the first test featuring rider Michele Pirro conducted at Misano World Circuit in early 2022. This racing program provided Ducati with critical data on electric powertrain integration, thermal management, and performance optimization that directly informs the street motorcycle patent.
Design Philosophy and Production Timeline
The patent filing in April 2026 reveals Ducati's commitment to applying combustion motorcycle principles-agility, balance, and rider-focused dynamics-to an electric platform rather than pursuing unconventional EV-specific architectures. The company prioritizes mid-mounted motor positioning, geared transmission, chain final drive, and tight chassis packaging identical to its traditional sportbike formula. This philosophy contrasts sharply with many electric motorcycle manufacturers who adopt hub motors, belt drives, or radically different frame geometries.
However, the patent does not confirm imminent production or provide specific launch timelines. Industry observers note that patents address engineering challenges rather than product development schedules, and Ducati's first electric production bike for public roads appears to remain several years away. The company's current electric motorcycle efforts concentrate on the MotoE racing series, with the supply contract extending through the end of the 2026 season.
Technical Advantages and Trade-offs
- Sensor relocation reduces motor width by eliminating shaft-mounted position hardware
- Indirect rotor position calculation enables slimmer motor housing dimensions
- Multi-plane gear stacking maintains narrow profile while preserving reduction ratio efficiency
- Chain final drive preserves conventional sportbike handling characteristics
- High motor RPM (18,500) allows smaller motor size through increased power density
- Potential accuracy limitations from gear lash require advanced compensatory algorithms
- Increased software complexity compared to direct sensor mounting
Packaging Optimization Metrics
Electric motorcycle width presents a critical engineering constraint because excessive lateral dimensions reduce cornering clearance, compromise rider ergonomics, and fundamentally alter the motorcycle's handling characteristics. Ducati's packaging-first approach addresses this by relocating components vertically rather than horizontally, maintaining the slim profile that enables aggressive lean angles during high-performance riding.
The patent drawings indicate a deliberate effort to keep the powertrain's lateral footprint comparable to Ducati's traditional L-twin and V4 combustion engines. This dimensional discipline ensures that riders experience familiar ergonomics and riding positions rather than the wider, more upright stance common to many electric motorcycles.
Field-Oriented Control Implementation
The relocated sensor strategy maintains compatibility with field-oriented control (FOC) techniques, which represent the industry standard for electric motor torque management and efficiency optimization. FOC algorithms require precise real-time knowledge of rotor position to properly align stator magnetic fields with rotor position, maximizing torque production while minimizing energy waste.
By calculating rotor position from gearbox shaft sensors using fixed gear ratios, Ducati's system preserves FOC functionality while eliminating the width penalty of shaft-mounted sensors. The engineering challenge lies in accounting for mechanical variables like gear backlash, bearing play, and drivetrain compliance that introduce position uncertainty between the sensed gearbox shaft and the actual motor rotor.

Why does Ducati's patent relocate the motor position sensor?
Ducati relocates the position sensor from the motor shaft to a gearbox shaft to dramatically reduce the motor's width, allowing the electric motorcycle to maintain a slim profile essential for proper lean angle and ergonomics. The system calculates actual rotor position indirectly using known gear ratios, trading sensor simplicity for crucial packaging advantages.
What motor specifications does the patent reveal?
The patent describes a transversely mounted electric motor capable of spinning at approximately 18,500 rpm, paired with a multi-stage gear reduction system and chain final drive. This configuration closely mirrors the specifications of Ducati's V21L MotoE race bike, which produces 110 kW and reaches 275 km/h.
How does the gearbox design contribute to narrow packaging?
The transmission stacks gears vertically across multiple planes rather than spreading them horizontally, building the gearbox taller instead of wider. This vertical stacking strategy maintains the narrow lateral profile critical for motorcycle handling while preserving efficient power delivery.
