Who says you can’t have independent rear suspension in a sport quad? Not Polaris.
POLARIS OUTLAW 525 IRS
For a time, Polaris and KTM were
joined at the hip, and in that period
the Polaris Outlaws were powered
by KTM engines. The motors were
the older design, with single overhead cams and carburetors. But one
model in particular was truly special. The Outlaw 525 IRS proved that
independent rear suspension was a
workable concept for a cross-country
quad. Others tried it, but only Polaris
made it really work.
WHY IT’S SO GOOD
Independent suspension was only
part of the story. The Polaris had the
same incredibly powerful motor that
KTM used in its own straight-axle
525XC. It was a beast and would leave
a Raptor 700 in the dust. Between
the plush suspension, great power,
reverse and high-quality parts, the
Polaris 525 IRS was capable of winning the Baja 1000 right out of the box.
As far as we know, no one ever tried.
HOW IT CAN BE BETTER
The Polaris is another one of those
machines where most modifications
were probably dis-improvements.
The exception was the airbox, which
was very restrictive. For this reason,
the KTM with the same motor was
considerably faster. Modification was
fairly easy. Actually, the biggest complaint was the styling. The Polaris was
one funky-looking quad.
If you want a 525 IRS, you had better
make it a hobby. Check the classified
ads every morning. Eventually, you
will come up with one, and chances
are the price will be good. It’s enough
of a cult quad that many owners won’t
know what they have.
