Specifications: 436 cc SOHC single, five speeds.

The 450-cc Mark 3 model was introduced in 1969, following the new wide-case 250/350-cc a year earlier. The 450-cc frame had an extra gusset along the top tube like Spaggiari’s racer, including a wider chain and sprocket and slightly longer Marzocchi forks. All 450s had a new type of Dell’Orto square-slide VHB 29 carburettor, and the bullet silencer was replaced by the cut-off Silentium type, which could be long or short. The bike on offer appears to be in sound condition and is finished in its original red and black, with some re-finishing to the paint. This model was produced for the Municipal Police and is known as “Vigili Urbani.” Its reduced 8.4-to-one compression ratio, solo seat and valanced front mudguard are all factory correct.
