In 1974 and 1975 Guido Valli used this Gori to become Italian Hillclimb Champion. The machine had a 123.6 cc (54 x 54 mm) Sachs engine. Running on a 13.1 compression ratio it produced 24.8 bhp at 11,600 rpm and was capable of 185 km/h (115 mph). Other technical details included 34 mm Bing carburettor, six-speed gearbox, Marzocchi suspension, 170 mm Fontana double-sided 2LS front brake, Motoplat electronic ignition and full cradle duplex frame.
A production version was offered for sale to private customers in 1975 and 1976.
In 1975 Gori introduced the 125 cc Sport Valli Replica, derived from the very successful Gori road racing machine. This used the same (very slightly detuned) six-speed Sachs engine, but had a full fairing, twin front discs, cast alloy wheels and sharp styling. Although barely road legal it was at the time the quickest 125cc street bike in Italy, with a claimed maximum of 92 mph.
By 1980 the Gori concern was concentrating practically all its efforts on off-road machinery, either motocross or enduro, using Hiro engines. Typical was the 125 RG. Its impressive specification included: a six-speed gearbox; Sachs Hydracross rear shock absorbers; Dell'Orto PHF30 carburettor with fully sealed air filter; 35 mm competition forks with rubber gaiters; Metzeler tyres; Magura levers; and unbreakable plastic for the mudguards, tank and side panels. All in all, it was a high class off-road racer with lights.
