The bike was in practice Minarelli 125 bicampione World category in 1979 and
1981 with Angel Nieto (only changes the color of a mechanical anti-dive on both
wheels and disc brakes of smaller diameter) following the death
Vittorio Minarelli, founder of the Bolognese, it was decided to give in to
Garelli (with which Minarelli had struck up an agreement for the supply of
engines for an eighth of a liter road) around the racing department, transferred
from Bologna to Sesto San Giovanni.
The Garelli GP debuted at the Grand Prix of Argentina in 1982,
the first race of the season, winning by Nieto.
At the end of the season the Spaniard was again World Champion, while his
teammate Eugenio Lazzarini was second.
The bike remained unchanged even during 1983 and 1984, allowing Nieto to win two
more world titles.
On the occasion of the Austrian GP 1983 made their debut a series of aerodynamic
upgrades studied in the wind tunnel center experience Orbassano FIAT.
For the '85 season, the bike was modified: the monocoque chassis was made of
aluminum instead of steel, changed the angle of the steering head (from 27.5 °
to 26 ° for improved handling), was fitted with a damper
steering and changed the supplier of suspension (until 1984 Marzocchi Fork Italy
after the front and White Power for the two rear shock absorbers).
Another fundamental change was, again in 1985, the change in the management
team, now in the hands of the IMF (Team Italy who had Lazzarini as sports
director and Fausto Gresini and Ezio Gianola as pilots): The motion is now
recognized for the new livery
white stripe tricolor of green-white-red (instead of red and black as in 1982).
Under the new management continued the winning streak Garelli,
with three titles until 1987 (two titles for Gresini and one for Luca Cadalora).
