Review

The 1977 MV Agusta 900 S Arturo Magni - Cento Valli represented a significant evolution in the MV Agusta lineage, building upon the already respected 750 S. This model, heavily influenced by the tuning expertise of Arturo Magni, aimed to enhance the performance and handling characteristics of the Italian marque. In its era, it found itself competing with other high-performance motorcycles like the Laverda Jota and the Ducati 900SS, all vying for the attention of riders seeking speed and Italian style.

At the heart of the 900 S Cento Valli is an 892.0 ccm (54.43 cubic inches) in-line four, four-stroke engine. This powerplant is capable of producing a maximum power output of 105.0 HP (76.6 kW) at a screaming 10000 RPM. Such power allowed the motorcycle to reach a top speed of 230.0 km/h (142.9 mph). Fuel capacity is a respectable 24.00 litres (6.34 US gallons), enabling reasonable range for spirited rides. The motorcycle's design showcases the engine as a focal point.

The riding experience on the 900 S Cento Valli is defined by its focused sporting intentions. While not overtly track-focused, the ergonomics lean towards a more aggressive posture compared to touring machines of the day. Expect a firm ride and responsive handling, demanding rider input and rewarding skilled operation. Comfort, while not the primary design goal, is adequate for shorter, exciting jaunts through winding roads. The suspension setup communicates road imperfections directly to the rider.

The MV Agusta 900 S Arturo Magni - Cento Valli from 1977 appeals primarily to collectors and enthusiasts who appreciate classic Italian motorcycles with a strong racing heritage. It is a machine for those who value the raw feel and direct connection to the road offered by motorcycles of that era. A mechanically knowledgeable owner is best suited for this machine due to its age and specific maintenance needs. It's a motorcycle that offers a unique experience, steeped in history and character.
