QUICKSPIN I 2023 KTM 300 XC

MY WOODS
WEAPON
I was sort of familiar with the 300
already. I rode a few laps on the
300 SX version a few months
back and knew the XC trim would
make it the perfect bike for this
race. A bigger tank, 18-inch rear
wheel, softer suspension, and
cross-country mapping highlight
the off-road XC. The main high-
light, however, is fueling, which
is now handled by an all-new
electronic fuel injection system,
which replaces the former Trans-
fer Port injection (TPI) system. The
new design uses a 39mm Keihin
throttle body with injectors and a
TPS sensor to improve engine idle
and fuel-air mixture. What you'll
probably notice most, however, is
having to premix your gas with oil
again. Oil injection is a thing of the
past, at least for the XC models.
The more trail-focused XC-W
(enduro) models still use the TPI
system, but we expect that to
change down the road.
The '23 300 XC also features
a new electronic exhaust con-
trol (aka power-valve), which
replaces the former centrifugal
ball-ramp mechanism.
The WP Xact fork is updated,
but the rear WP Xact shock is
new from the ground up.
