Template:Infobox Motorcycle The MV Agusta 350 Ipotesi (meaning Hypothesis) was a motorcycle crafted by the Italian company MV Agusta during the years 1975 to 1977. This model was developed by renowned Italian designer Giorgetto Giugiaro and took inspiration from the earlier MV Agusta 350B#350 B Sport Elettronica variant.[1] In total, production included approximately 1,991 units of the "Sport" version[2] alongside 350 examples of the “Turismo” edition.[3]
Background
After the passing of Domenico Agusta in 1971,[4] MV Agusta encountered a rapid downturn in its financial health, largely due to stiff competition from affordable yet high-quality Japanese motorcycles and persistent labor disputes. To regain market traction in the middleweight segment, Giorgetto Giugiaro—who had previously designed the Suzuki RE5—from his firm Italdesign Giugiaro was tasked with creating a fresh and appealing design. The resulting prototype featured bold horizontal lines combined with sharply defined edges.[5] This concept bike was unveiled for the first time at the 1973 Milan EICMA Motorcycle Exhibition.[1]
Features
Evolving from the 350 B series, the 350 cc four-stroke OHV parallel twin incorporated redesigned casings that complemented the bike's overall aesthetic. The sharply contoured cylinder heads aligned with the machine’s linear design, embodying a cutting-edge engineering approach for its time. Power increased from 27 hp (20 kW) at 7,800 rpm to 34 hp at 8,500 rpm.
The frame was newly constructed solely from steel tubing, replacing the previous combination of tubing and sheet steel. The petrol tank, seat, and side panels were all redesigned; notably, the seat integrated the rear mudguard, while the side panels featured slots that echoed the engine’s cooling fins.
For braking, Scarab disc brakes were installed—dual discs upfront and a single disc at the rear. The suspension comprised Ceriani forks, and cast alloy wheels were introduced. This model marked the first Italian production motorcycle to feature three disc brakes alongside alloy wheels.
An optional full fairing was also offered to buyers.
350 Ipotesi GT
The 350 Ipotesi GT, alternatively called the 350 Ipotesi Turismo, was designed as a touring variant. It adopted a more traditional rear seat configuration with a separate rear mudguard and higher-set handlebars. Unlike the sport model’s painted finish, this version featured chrome-plated mudguards and exhaust pipes. The fuel tank was distinctively finished in gold and blue hues.
While it retained twin front disc brakes, a drum brake was used on the rear wheel. Additionally, wire-spoked wheels replaced the alloy ones found on the sportier version.
Hansen & Schneider special models
During the mid-1970s, German MV Agusta importer Hansen & Schneider secured manufacturing rights for MV Agusta motorcycles. They developed two 500 cc variants based on the Ipotesi platform.
- MV Agusta 500 S (1976–77): This model featured an enlarged bore of 75 mm from the original 350 cc engine, resulting in a displacement of 472 cc and delivering 53 hp (39 kW) at 8,900 rpm. It came equipped with larger tires—3.00x18 at the front and 3.50x18 at the rear. A detuned option producing 43 hp (32 kW) at 8,200 rpm was also available.
- MV Agusta 500 SS (1977): Offered as a special-order racing machine, this version had a thoroughly reworked engine with double overhead camshafts, generating 66 hp at 11,100 rpm. Only five units were produced.
