WHAT KIND OF
DOES IT HAVE?
A fully manual six-speed with a
slipper clutch to improve engine
braking control. Chain final drive
is used to the rear wheels only,
and there is no reverse.
IS IT SIMILAR TO A UTV
IN SIZE AND WEIGHT?
It’s similar to some UTVs in some
respects, but it’s definitely its own
animal. It’s 73 inches wide, an inch
wider than the widest sport UTV, Can-Am’s Maverick X3 X rs. The wheelbase
is 81 inches, a bit longer than a RZR
S 1000’s 79-inch wheelbase. Full of
fuel and ready to drive, it weighs just
1200 pounds—that’s more than 300
pounds less than Yamaha’s YXZ1000R!
WHAT KIND OF
SUSPENSION DOES IT HAVE?
It has unequal-length, double-A-arm suspension front and rear
with compression-adjustable Fox
2.0 shocks. The A-arms allow the
camber gain rate to be adjusted to
tune the car’s cornering grip. Dirt
oval tracks don’t have jumps, so
the R1DT’s 6 inches of front and
rear travel are more than adequate.
The short-travel suspension also
enhances the car’s cornering stability
and sharpens steering response.
FEATURES DOES THE
R1DT BRING TO DIRT
Yamaha plans to offer retail financing
for the R1DT, as it does for many of
its other products. Financing for race
cars is a rare thing, so Yamaha hopes
The double-overhead-cam, 16-valve
allow a wide range
of engine tuning
options. Even the
braking is tunable.
The R1DT uses chain drive to the rear wheels only. Chain drive is more efficient than shaft
drive and allows quick gearing changes.
Yamaha’s dirt oval racing concept car puts the
170 -horsepower engine from the four-cylinder
R1 sport street bike in a vehicle that weighs
just 1200 pounds full of fuel and ready to rip.
