When you’re up to your skidplate in mud,
the last thing you need is
a gearbox designed to win Daytona.
^A/e’ve got a gearbox that has beaten Day-
tona, six years in a row, but we’d no more send
you into the boonies with that gearbox than
we’d send you into Baja with a Ferrari. All the
things that make our close ratio five-speed a
jewel on a racing bike make it a roving dis-
aster on a dirt bike.
So for our Enduros® we’ve put together a su-
per boondock beater—a wide ratio five-speed
that puts the power where you need it.
The difference is this:
Racing machines do most of their travel-
ing at relatively high speeds, so they’re
geared for top speed. In the dirt, the
going is much slower and tougher.
You need a gearbox which gives low
end performance. Ours does.
You could solve it by putting a
larger rear sprocket on the bike.
But that would effectively lower all
the ratios and leave you with a
pretty slow top gear.
That’s why we spread our ratios
out. Our Enduro low gear is a stump
puller that’ll take you right up
a wall if you can get the
traction. Top gear, on the
other hand, is right where it ought to be for
covering a lot of flat ground in a hurry. Second,
third and fourth sort of split the difference. You
can see what we mean from the diagram here.
This way, when you’re up to your skidplate in
mud and hoping for a lot of torque, you’ve got
it. And when there’s nothing but open field in
front of you, you can fly like the wind. It’s a
crucial difference, but one that a lot of other
dirt bikes seem to have missed. You’ll find
this type gearbox on all the Yamaha
Enduros, including the 125 AT1-C
shown here. The AT1-C has a lot
of other differences, too. Like high
performance Enduro forks that can
take a 10-foot plunge without put-
ting an abrupt end to the day’s
riding. Five-port power to
make the most out of every
cc in the engine. Dustfree,
waterproof brakes, separate
instruments and a lot of
other niceties that all add
up to one thing: a better machine.
