Q: IS THE 2016 YAMAHA YZ250X BETTER THAN
THE 2015 YZ250X?
A: Of course it is, because there has never been a
YZ250X before. Well, that’s not entirely true. Yamaha made
a WR250 two-stroke from 1989 to 1996. It had many of the
traits of the 2016 YZ250X. Why did they stop making the
WR250? The WR250 was heavy and less powerful than the
YZ250, so many racers opted to convert a YZ250 into an
offroad bike by putting on an 18-inch rear wheel, bigger
tank and flywheel weight. When KTM threw all of its effort
into building its EX and XC offroad models, with countless
models in every displacement, the WR250 went out of
fashion. Last year, Yamaha began to fight back against the
KTM juggernaut by releasing the 2015 YZ250FX four-stroke.
This year the Blue Cru has added the YZ250X two-stroke
and YZ450FX four-stroke.
Q: HOW MUCH DOES THE YAMAHA YZ250X
A: The 2016 YZ250X is $100 more than the YZ250,
$9 less than the KTM 250SX and $1100 less than a KTM
250XC. The suggested retail price is $7390.
Q: WHY IS MXA TESTING AN OFFROAD BIKE?
A: Two reasons: (1) We love two-strokes. ( 2) The
Yamaha YZ250X can be ridden in the desert, woods,
enduros and on trails. And, as the MXA wrecking crew
hoped to prove, it can be raced in motocross as well.
Q: WHY NOT JUST CONVERT A YZ250 TO AN
OFFROAD MODEL LIKE RACERS HAVE BEEN
DOING FOR YEARS?
A: You could, but for riders who focus more on offroad
riding than motocross, Yamaha added enough offroad parts
to make the YZ250X lean and mean. That includes softer
suspension, a wide-ratio transmission, kickstand and 18-inch
Q: HOW DOES THE 2016 YZ250X DIFFER FROM
ITS YZ250 BROTHER?
A: Although the basic platform is all YZ250, there
were quite a few changes to make the YZ250X more
(1) Cylinder head and cylinder. The head volume was
increased by 2.1cc from 21.5cc to 23.6cc. This added volume reduced the compression ratio from 8.9:1 to 7.9:1. The
exhaust port height was raised 0.5mm, and the power valve
shape was updated to match the exhaust port height.
( 2) Pipe. The YZ250X expansion chamber is totally new
but not completely different. Essentially, it is designed to
