A dual-A-arm front-suspension system
is found on the DRR DRX 90 LTD. It
and the Can-Am DS90X are the only
two minis with this feature. It provides
better cornering and, in this case, 5. 5
inches of travel.
Rath Racing supplies parts to some of
the best ATV racers in the world, and
you can get them for the DRR minis as
well. This footpeg/heel guard/nerf bar
combo replaces standard plastic floorboards that come stock.
A non-slip, ribbed seat cover comes
standard and looks and works great.
A single-shock swingarm and standard chain drive get power to the ground on the
DRR. Wheel travel is 5. 5 inches, and the LTD model uses Carlisle (ITP Holeshot)
tires. Duros come on the stock machine.
In the ATV national and most regional series, 90cc quads are put in a class for kids
ages 9–12 to race. Our rider, Justin Lundin, was a bit small for his age and fit perfectly.
ence between this and most other
minis is the clutch setup.
DRR tunes the clutch as to not
engage until halfway up in the rpm
range. So you have to stab the throttle
and wait for the revs to build, then
it starts moving forward. Since the
clutch engages so late, the motor is
already making a lot more horsepower than it is at lower revs. This launch-es the quad off starting lines fast and
out of corners even quicker. On the
downside, it makes the machine a
little tougher to control in slow, rough
situations. Again, this quad is aimed
more for an experienced rider, and
the clutch can be tuned for a different
powerband feel if needed.
When we are on a tacky track, the
quad hooked up and shot from turn
to turn quick. The low-end grunt was
there too. You do have to wait for the
engine to rev and take off; it would
dig out of the corner hard even at
high revs. In those turns, the 90 would
carve if you gently arched the han-
dlebars or would slide the rear end
if you flicked them. It was cool to see
the kids flick the bars and let the quad
fishtail out of the corners. But if they
held the bars straight, the quad would
track perfect all the way to the next
turn and over the next jump.
Speaking of jumps, the DRX 90 takes
them like a big quad. With 5. 5 inches
