2018 KAWASAKI KX250F
(1) Engine changes have resulted in
improved power and torque through-
out the rev range.
( 2) Up front are revised Showa
48mm Separate Function Forks (SFF)
with works-style internal construction
and one coil spring in the right leg.
For 2018 revised settings contribute to
greater precision over braking bumps
and through corners.
( 3) The 2018 Uni-Trak rear suspension’s Showa shock features revised
settings. These 2018 changes contribute to improved ride feel, traction and
( 4) There is a new throttle body and
fuel-injector angle for increased torque
throughout the rpm range.
( 5) A new fuel pump features
increased output pressure for better
( 6) The intake boot has been recon-figured. The intake path has been
revised with a shorter intake funnel
and redesigned duct.
( 7) The 2018 KX250F engine gets
a new intake camshaft, advanced
valve timing, new cylinder head with
revised intake tract and a piston with
a new compression ratio ( 13.4:1).
( 8) The exhaust header is longer,
with a larger tubing diameter to
increase torque and power output
while retaining the resonance chamber. Riders should feel more power
from low-to-high rpm with increased
( 9) The dual-injector fuel-injection
system of the KX250F uses one injector downstream of the throttle body
with a second injector stream located close to the airbox. The downstream injector is used to help ensure
smooth, instant response and features
a finer atomization with more holes
in the injector itself. The downstream
injector creates that stronger low-to-midrange power and quick throttle
response, while the upstream injector
is charged with providing top-end
