Founded in 1933, Dell'Orto is one of the most revered names in the motorcycle industry, and a business that has adapted to, indeed led the changes in motorcycle performance in the past three decades.
Widely known for its Injection Systems, its MotoGP experience with its RSV Aprilia throttle bodies and with the Moto3 ECU (Electronic Control Unit), has resulted in the release of a third generation of electronic fuel injection components and systems for motorcycle engines.
The new Monnalisa ECU, which completes the DELLORTO ECU range, has been designed to meet the requirements of the EURO5 and BS6 regulations that will enter into force in the coming years. The latest development includes traction control, start-and-stop and advanced OBD2 on-board diagnostics. DELLORTO ECUs support single and two-cylinder engines, 2- and 4-stroke, with air or liquid cooling.
In 2019, Dell'Orto took up the electrification challenge, taking part in the MotoE project with the supply of the data acquisition system: datalogger, inertial measurement unit, brake sensors, suspension sensors, and TPMS receiver and sensors (tyre temperature and pressure).
Through this new electrical experience, Dell'Orto has recently established a close cooperation with Energica for the development and production of dedicated "Power Units" for EVs of small (power range up to 8/11kW) and medium sizes (power range up to 30kW). The project aims at offering technologically advanced solutions to the major manufacturers operating in the EV 2-wheeler market, "combining the unique know-how of Energica in electric motorisation with Dell'Orto's design skills in injection systems, as well as productionisation skills and distribution networks in Europe, China and India. The agreement foresees the common development and commercialisation of an innovative system based on the combined know-how of the two companies".
Dell'Orto's two mechanical and electronic throttle body lines have been "improved and expanded with innovative solutions. For mechanical throttle bodies, Dell'Orto has developed a compact air by-pass actuator and a 3-in-1 combined sensor that include contactless TPS, temperature and air pressure sensor functions".
The company's electronic throttle bodies are available with "specific solutions for 1 and 4-cylinder engines. Thanks to a new patented design, it is possible to control the main throttle and a secondary throttle with a single actuator; this improves driveability and emissions at low speed".
This year Dell'Orto is also introducing a complete range of sensors: TPS contactless (single and double output), 3-in-1 sensor (TPS, temperature and pressure), a dual map sensor for twin cylinder applications and an innovative contactless gear position sensor.
"A great configuration flexibility allows Dell'Orto fuel pump modules to be a reliable market player. They are available with pre-filter, fine filter, pressure regulator and level sensor and they can be fitted on top or below the fuel tank".
For exhaust valves, Dell'Orto is already producing exhaust gas recirculation valves for cars and now it has developed and industrialised an exhaust valve for motorcycle engines. The valve is able to optimise and enhance the sound of the engine. The exhaust valve is produced in a stainless steel that withstands the high temperatures downstream of the catalysts - required for EURO5.
In addition to electronic ignitions, Dell'Orto is continuing with the development of its patented Electronic Carburation System (ECS) - "perfectly suited for 50 cc mopeds and for engines with small displacements for the Asian market, which has recently obtained the patent in India, the most important market for production volumes in the world.
In a strategic development plan that has been designed in line with the new demands of the world market, Dell'Orto has recently expanded its footprints both in India and China. Dell'Orto has a production site in India, where important production has begun in partnership with the main local producers. It is a highly technological plant, "organised by Italian know-how and expertise and fully compliant with European quality standards. It started in 2006 with the production of mechanical throttle bodies for the local market and of injection systems and for export and has increasingly consolidated its position on the Indian market as one of the leading local players for injection system components.
In February 2018 a joint venture was signed with Varroc to further strengthen the presence of Dell'Orto in India as System Integrator for motorcycle injection systems. Varroc will support Dell'Orto in the production of the new DaVinci and Monnalisa electronic control units.
The company's Chinese market presence is managed by Dell'Orto Shanghai Trading Company. Operating for ten years already, it is the Chinese motorcycle market leader in electronic carburetion systems for EU4 and EU5 homologated mopeds and small displacement motorcycles. Dell'Orto China is a partner for the development of the complete injection system for the upcoming China Stage IV regulations and for the export. In 2017 a joint venture was established for the production of motorcycle fuel modules and Dell'Orto says it has "brought its expertise to quality - gaining the strictest AKLH12 validation tests".
