SPANNING THE AGES
I’m interested in buying a 2016
Yamaha YZ250X. I race more
motocross than cross-country
races, but think that the X would
be a better bike for me than
the regular YZ250. What are the
biggest problems for the YZ250X
on a motocross track?
The only real problem is the
gearbox. Although first, second
and third gears are well-suited to
the typical track, there is a big
gap between third and fourth
and an even bigger gap between
fourth and fifth.
OLD WHAT’S HIS NAME
Can you tell me the name of the
designer who came up with the idea
of the Husaberg upside-down engine
design? I want to write a paper on
that engine for my engineering class.
Why did it disappear?
Swede Jens Elmwall designed the
engine. It failed because it didn’t
sell, which is the kiss of death for
any controversial idea. The MXA
wrecking crew felt that Jens Elwell’s
centralization of mass ideas were
ruined by the fact that it was in
a bike that weighed 250 pounds.
Better than centralizing mass is
getting rid of it.
NO MORE HARPING
Never a fan of KTM in the past,
I have softened my opinion of
them over the last few years. I was
intrigued when Roger DeCoster
went there and disappointed when
Suzuki lost Ryan Dungey to the
orange brand. But I must say, after
reading the “MXA 450 Shootout” in
the January 2016 issue, my opin-
ion has changed completely. The
paragraph labeled “Why Should the
450SXF Win the Shootout?” was an
eye-opener. It’s hard to badmouth
the bike with the most horsepower,
broadest powerband, lightest weight,
electric starting, hydraulic clutch and
class-leading brakes. I used to harp
on the 4CS forks as the reason I
would never buy one, until I rode my
friend’s ESR-suspended 450SXF. No
more harping. I’m sold.

How old is James Stewart?
James is 30 years old. If you plan
on buying him a present, he already
