"In 1985, despite the announced retirement of the MBA racing department, Paolo Pileri together with some mechanics developed a new 52 ° V-twin engine. Around that engine, a wooden mannequin was first built, then a prototype with a boxed aluminum frame. Paolo himself, at Misano, set the track record. Shortly thereafter the MBA closed, Pileri saved the bike, then carefully restored by a great enthusiast like Genesio Bevilacqua. Thanks Genesio, for having saved from oblivion this bike and its history."
