Sammy's Linto Aermacchi


Coupling two Aermacchi 250 cylinders; Lino Tonti (financed by the Citroen dealer Umberto Premoli) created the "Linto 500 GP" a race beast, available for private racers, that competed with good results (Gyulay Marzowszky was second next to Giacomo Agostini in 1969 championship) in the World Motorcycle Championship from 1968 to 1970.
The initial design of the engine was for a DOHC with 4 radial valves, but the funds available were not sufficient and, therefore, the solution adopted was to use the cylinders (72 mm bore) and heads with rods and rockers of the Aermacchi Ala d'Oro 250 with a new block. The Linto prototype, still in developement, produced 65 hp at 12.000 rpm.
Thanks to the high power, good torque, and light weight, the Linto was very fast. Keith Turner, for example, won at the Mettet Internationals 1969, where his bike was timed at 160mph on the Mulsane straight (20mph faster than Norton and Matchless), but was very fragile and, when Tonti was hired by Moto Guzzi in 1969, the developement of the bike ended. - Dogwalker

The trellis frame of the Linto was built by the specialist Milanese frame builder Stelio Belletti, with Ceriani suspension and Fontana drum brakes, resulting in a sweet-handling lightweight 142 kg bike . . . . - Mike Hanlon
Along with producing a great deal of power, the engine vibrated so much that it sometimes caused the frame to crack, which is how this bike got it's reputation for being 'fragile'.
