The Original ! The Legend ! The Treemezzo !

IMG_0226_800_600_gkThere are a lot of denominations for this example of the wonderful art of italian motorcycles put on the market in 1973, the most common will remain “Treemezzo”. Rather 3 ½the connoisseur will argue and in fact it is mostly the badge on the side cover which remains in mind of the observer. But not only the badge stuck out, when the new 3 ½ models were presented to the public in 1973. Even technically the bike was ahead of the times. The 3 ½ had a 72°-V-twin, for the fist time there was an electronic ignition and a 6-speed gearbox in a series-bike. The Heron combustion chamber and the toothed belt driving the central cam shaft are mentionable. The brilliant constructor was Franco Lambertini. The touring model l 3 ½ T came on the market in 1973, one year later followed the sport version 3 ½ S.The 344 cc engine hat 35 HP in the touring version and even 39 HP in the sport model. The torquey and durable engine was constantly refined, but the main concept remained the same over the years. It was used until 1991 in differing displacement and performance variants, up to a prototype with 478 cc and turbocharging.

But it wasn’ t solely the engine concept which contributed to the creation of the legend 3 ½. Historically the make had reached already much with his known driver Tarquino Provini. From the early Rebello from 1955 they developed the 250 GP Bialbero, on which Tarquinio Provini was extremely fast even in international races from 1961 on. In 1963 he missed the world championship by two points against Jim Redman on a 4-cylinder Honda. With up to 40 HP this is said to be the fastetst 250 cc monocylinder in history.

The 3 ½ doesn’ t only convince by it’ s technical values, also it’ s design is legendary. Appearing in the rear view mirror, it resembles more to a moped than a motorbike, thanks to her slim silhouette. It seems to be much smaller, much more delicate than it’s sound implicates. Also the chassis was always excellent. On small and winding roads it was an easy game with the Treemezzo, to cause sudatoric experiences to drivers of big and obviously stronger bikes.
