KFX 450R Project Quad Build - Part One
Front Suspension System & Steering - ::Continued::

Stock
Kawasaki KFX 450R Front A-Arms, Suspension,
& Brakes |
With the machine prepared, removal of the front
tires kicked off the project as the stock meats
were removed, which is a pretty straight forward
operation. With the tires removed, we could flow
through the removal of the stock front end, which
for us starts at the brake lines and draining the
brake fluid as we would be replacing the stock lines
with stainless lines from Streamline Performance
Braking.
With our stock lines drained and removed, it
was time to start disassembling the front end
components, which immediately jumped out as being
different in the way they mount to the chassis.
Although it may appear at a glance a standard
front end, the front end has many differences
over its competitors starting with how the lower
arms mount to the frame. Mounting bolts run through
one arm, chassis and again back through the other
arm, which provides a stronger and more durable
mounting than conventional a-arm mounting.

The stock
KFX 450R brake lines are easily removed
by removing a few bolts and brackets,
which are attached to the frame &
A-Arms
|
The
KFX450R A-Arms are mounted totally different
than any other stock A-Arm with the bolts
going through the frame & connecting
both A-Arms together on each side of the
frame |
There are a few areas on this machine that are
totally modular due to the aluminum construction,
such is the case on the small bracket that secures
the stock front brake lines at their junction
in the center of the frame. On most ATVs this
mount is welded to the frame, however on the KFX
450R it is secured with 2 small bolts and it can
be reattached or left off when using aftermarket
brake lines. Removing the components was straight
forward and work time for disassembly was right
at the one hour mark. I am happy to report that
there were no big surprises during disassembly.
One small tip is that when removing the upper
shock mount bolt, you will need to remove the
headlights or atleast one 8mm bolt so that the
headlight can be lifted slightly to allow the
bolt to clear the headlight housing.

|
To remove
the KFX 450R front shocks, the headlights
need to be removed or the front fenders
to make room for the upper shock bolt
to be removed
|
With
all the front suspension components are
removed, the KFX450 bare aluminum box tube
frame is revealed, which is unlike any other
production Sport ATV |
With the a-arms, shocks and brake lines removed,
it was time to tackle the stock steering stem,
which would be replaced with a +1 Houser Anti-Vibe
unit. This was the first look at how much went
into this machines design and just a sneak peek
at the challenges the manufacture faced when working
with the alloy frame. Standard stem designs utilize
a bearing and retaining clip(Honda) or locking
ring (Yamaha) where as the Kawasaki was a bit
more involved. Two small allen bolts hold a mount
in place and must be removed so the stem can be
lifted from the chassis.
Once the stem is out, you can then access the
larger retaining nut and retain the bearing and
plate for use when reinstalling the aftermarket
stem. With everything required for the replacement
parts removed, we were ready to begin our machines
transformation from its stock state to a more
race ready stance.

Houser
Racing's Slicast A-Arms come retail
packaged, which not only helps protect
the products during shipping, but it also
keeps the parts secure and safe from being
lost before installation, and the steering
stem also was retail packaged
|
The
Elka
Suspension's Elite ATV Front Shocks
were ordered for the project because they
come with both High & Low Speed Compression
adjustment along with rebound & pre-load
adjustability, which is a great combination
for dialing in the shocks |
