MV Agusta 3: It Is What It Was It might like something from the but this all-conquering MV Agusta GP 500 is new from the tires up.

The legacy of MV three-cylinder racebikes and their world championships is not just a fact of numbers: It has been in steel and aluminum and magnesium. and Maurizio Mascheroni and Enrico the men of HRT who made major contributions to the of MV Agusta’s new 675 F3 . have also life to a perfect copy of a motorcycle that ran its last in 1974: the three-cylinder MV Agusta GP

Why, you ask? Why not? was a member of the legendary MV Agusta team back then and has copies of all the original drawings (he is Director of the MV Agusta Museum in Costa).

HRT was able to duplicate the molds for the sand-cast engine, then components using the same and aluminum alloys—as well as the components, of course—to the exact specifications. I didn’t dare ask how big the investment was, let alone the in man-hours.

But passion is a major in motorcycling everywhere, and in this a number of very exclusive came into play, the pride of having played a role in the building of the MV myth to the fact of living near the old MV factory in Cascina Costa. The bike is impeccable in duplicating the down to the mold of the fiberglass and its leather trim, as well as the Ceriani GP fork, Ceriani four-shoe front drum and 18-inch wire wheels. about the only things not 50 years ago are the modern Avon

When Giacomo Agostini saw the he immediately ordered one for himself and it to the Isle of Man for an unforgettable lap of honor—the MV being the bike that so much to making him one of the greatest of the sport.

The original MV Agusta engine started life in based on the sketchy inputs of Domenico Agusta himself. Not an by trade, the Count did possess a enthusiasm that gifted him a number of technical intuitions. One of the brilliant was the idea of developing a GP three-cylinder out of the very successful GP 250

The first edition had individual and heads, with two valves per set at a 91-degree included angle standard of the time) and hairpin springs.

Almost immediately, the potential of design appeared to be limited, so a Count Agusta called for a evolved design. Chief designer Mario Rossi and technical draftsman, young Sironi, had seen this and they already had drawings for a much more advanced head. Induction evolved to valves per cylinder at a 73-degree angle.

In 350cc configuration, the new MV Three was moderately oversquare at 56 by and in its final edition of 1972, it 68 horsepower at 15,000 rpm. By compression was a healthy 11.5:1. was by three Dell’Orto SS30 carburetors, and the 23mm inlet and exhaust valves were set at a included angle.

In the hands of Agostini, the GP 350 Three won World Titles in a row between and 1972.

The same engine was enlarged from 350 to a full and had an even more brilliant at that capacity. It won seven Titles in a row from 1966 to all of them also under bringing the total to 12!.

In 500 the GP engine grew to 62mm by with 11:1 compression and valves set at a 73-degree included In 1972, included valve went to a more conventional 56 using 24mm inlet and exhausts. In this form, the GP 500 reached a maximum output of hp at 13,500 rpm before running its race in 1974.

The HRT engineers adopted those specifications when they life to their replicas. always loved the MV Three than the Four, which he too rough and aggressive. In its technical the GP Three followed what at the were regarded as the golden for extracting maximum power a motorcycle engine: pressed-together con-rods turning on needle roller- or ball-bearings everywhere and distribution.

Magnesium castings used wherever the metallurgy of the allowed.

It still is a lovely engine, compact and light, of course, allowed a compact and racing bike to be built it. In terms of specific output, the new 675 F3 reaches for no less than 192 per liter, with total while the GP 500 made 168 hp/liter at its level of tune.

But, would you dare the terrific scream of the old stormer the ultra-civilized song of the new zapper? You can it here:
