KTM250sX f FACTORY EDITION
Even though the KTM’s horsepower is
still located mostly at high revs, it gets
there much more willingly.
So, what’s the bottom line on the weight loss? The new
bike checks in at 222 pounds without fuel on the fabulously accurate Dirt Bike scale. That places it in a three-way tie
for lightest in class, with the Honda and Yamaha logging
identical numbers. And, those bikes don’t have electric
FASTER AND FASTER
KTM already had the fastest bike in the class. The
horsepower was a product of rpm; the bike didn’t really
start going crazy until the revs reached critical mass.
Unfortunately, most riders don’t operate in that zone. In
the middle of the powerband the bike wasn’t anything
special, and that tended to make the motorcycle less
appealing to novice and intermediate riders. As delivered, the Factory Edition has a little more of everything. It
makes more power down low, has more in the middle and
makes even more on top. It’s still the fastest 250F you can
buy, only more so. A much more significant improvement
comes in accessibility. You can get up to the power much
easier because the motor revs more freely. It responds
more readily to a quick hit on the clutch lever.
You can choose from among three ignition maps. A
handlebar switch lets you choose between two of them on
the fly. Position number one is always the standard map.
even something you dream up on your own, providing you
have KTM’s programing software. Much to our surprise,
almost all our test riders liked the aggressive position
best. It seemed to make the bike much faster everywhere,
with no penalty in rideability. It isn’t a subtle change; you
know exactly which map you’ve selected. KTM engineers
say that the difference is hard to document on a dyno.
This is probably because dyno runs are generally made
with the bike wide open. The aggressive map makes the
bike respond more quickly to partial throttle openings. It
also seemed to make the powerband wider. It’s a no-loss
The silencer is shorter and mounted farther forward for
more centralized mass.
