Between the end of the 70’s and the beginning of the 80’s,
factory teams from Japan totally ruled the 125 class of the
World Championship Motocross with their incredible and
ultra-special factory bikes, like the fantastic Suzuki RA 125,
wich was the first 125 King rode by guys like Gaston Rahier,
Akira Watanabe, Harry Everts, Eric Geboers and Michele
Rinaldi. Suzuki won the first ten 125 World Championship
Motocross in the history, from 1975 to 1984.
European production is in a quite difficult situation: there are
few money for the factory teams, and the fight against Asiatic
player is very hard, for factory bikes and for productions to.
For 125, Only KTM, Gilera and the incredible little TGM from
Langhirano (Parma) gave good performances at high level,
but surely not in a suffisant way.
In those years, KTM developed hard his 125 MX bike,
and so the production machine is a wonderful bike,
and the factory versions are very good to: in 1979 Mauro
Miele is the first Italian rider to win a World MX GP (CH),
and durin the 1981 season, another italian rider, Giuseppe
Andreani, was in first position on the championship for long
time, before finishing sixth.
For 1982 austrian technician thought to a something of totally
new, wich could be not only the works bike to win World
Championship races, but basically the prototype of the
production 125 bike for the future.
The KTM 125 MX-Werkesmachine (wich is something like
“Official Works” in german) built for Beppe Andreani and for
the 1982 season, is something of different from the other
factory bikes, and the big differences are from the engine:
This little block has in fact the possibility of change the
scavenging system, passing from a rotating valve to a
reed-valve (on the carter pump) in something like two hours
of work by factory mechanichs...
