Suzuki set the motocross world on fire when
they introduced their first RM250 a couple of
years ago. The bikes were so good - compared
to everything else around - that the 250cc
support class at the 1975 U .~ . 500cc
Motocross Grand Prix was almost an
all -Suzuki show . The RMl!50 brought
Suzuki out of the dark ages in the
l!50cc motocross division, and pumped
new interest and sales into Suzuki
dealer showrooms.
Now. in 1977. Suzuki has taken the

was the main Suzuki rider then. 1 had

unusual. Now with the racing and
production together they work very
closely. The bike's development since
that time has improved greatly."
'Com pared to the RMl!50B . the
biggest im provem ent on the RMl!50C
is the addition of an air-oil fork , From
hard adobe to soft sand the fork did
its job. The ,9.8 _inches of travel
