The KX250 two-stroke remains
unchanged for 2007. Last year the
motocross industry found itself in a
state of panic upon discovering the
absence of the KX125 in Kawasaki's
lineup. But rest assured, the mighty
eighth-liter machine is still in produc-
tion. Kawasaki did not pull the plug;
U.S. distributors have simply
stopped carrying it. But like last year,
the KX125 is still available in North
America, courtesy of our wild, exot-
ic neighbor to the north (Canada).
So dry those tears, eh?

The 2007 KX250F also has a revised frame, but con-
versely has increased rigidity, designed for more a more
agile ride. Kawi aims at better response off the bottom
via a longer, straighter airbox funnel, and more top end
with a revised piston crown. The 250s new titanium
valves have thicker skirts for increased durability. A new
swingarm, revalved suspension and new springs (front
and rear) balance the stiffer frame.

Kawasaki gave a lot of individual attention to its four-
stroke models this year. Both received refinements
to the engine, frame and suspension, but the
changes are unique to each bike. The only shared
features of the 2007 KX-Fs are a five-speed trans-
mission and color-treated hubs. Modest revisions on
the KX450F focus on improving bottom and
midrange power, but the biggest change for '07 is
the chassis. The new frame has reduced rigidity in
the main spars to allow for more torsional flex. It is
also wider at the ankles and narrower around the
seat for improved ergos. DLC (Diamond Like
Carbon) coating on the fork sliders along with new
seals promise less stiction. Front and rear suspen-
sion revalving, a larger titanium header and revised
ignition timing complete changes to the KX450F.
