Whether your ride an Aprilia, Ducati, Suzuki, Yamaha, Honda, Kawasaki bike
you should know that our frame sliders and other sportbike protection accessories
are meticulously designed and manufactured to
provide the optimal
balance of extra protection for your motorcycle's frame and bodywork
while not transmitting excessive forces to your frame or engine
mounts.
The choice of
frame slider material was chosen to best withstand impact, abrasion and to
scrub off
speed
in the event of a lowside.
Our frame slider designs allows impact forces to be transmitted to the stronger
area of the frame instead of the vulnerable bodywork. Other frame slider
manufacturers may use fittings or brackets that are cast from aluminum or
recycled aluminum
scraps that have a looser and therefore weaker grain structure. All our frame
slider brackets and fittings are machined from high grade billet aluminum.
This is considerably stronger than those made from 'cast' aluminum
or aluminum scrap.
All our frame sliders and other sportbike
protection accessories feature machined aluminum inserts
which ensure the strongest possible
contact
between the frame slider, bolt
and frame of your motorcycle. Additionally all our frame sliders come
with high quality
components like replacement galvanized 12.9 grade hardened steel socket
head cap screws, 304 grade stainless steel washers and aircraft
grade lock
nuts(where applicable).
All these features you are not going to find on products from other cheaper brands.
Our components were carefully chosen
so as to construct a system consisting of a series of staged
sacrificial items
during the event of a lowside or slide. No system is
fool proof but a lot of work and thought had gone into our
designs to try and provide our customers the best value
for their money.
Fasteners
We use mostly 12.9 grade (176,000 psi tensile strength) hardened steel socket
head cap screws for our slider to frame attachments. Most socket head cap
screws of this type are supplied for use as flywheel or connecting rod bolts. Our
choice of bolts for this mounting configuration is so that they will bend
instead of snapping when subjected to excessive stresses. They are almost
always supplied in black finish but we take the extra step of having them
plated for better corrosion resistance. This may affect their exact thread
tolerances in some cases. Another thing we've been asked this a lot: "Why
socket heads instead of standard hex headed bolts?" The answer is simple.
A bolt fits into a hole in the slider. To tighten that bolt you will need
a hex drive or a socket drive. If you use a socket because it's a hex head
bolt, the hole in the slider needs to be bigger to accommodate the size of
the socket,
requiring
the slider
puck to either be bigger overall, or thinner walled. Hex drives are smaller
profiled and therefore need a much smaller hole in the slider for the drive
to be inserted. Socket head bolts are also much harder to come by, especially
in metric and non-standard pitch configurations. They are considerably more
expensive, but we feel that they are a worthwhile expense. We do not use
hex head screws, only socket heads and they are all either electroplated
or stainless steel. Never black oxide coated.
We also use stainless steel socket head cap screws for attaching sliders to brackets
(in street no cut model frame sliders kits). Usually they are of Grade A2 (304)
stainless steel with a tensile strength of about 101,000 psi. This type of fastener
was chosen as they are meant to snap off on excessive impact before transferring
that excessive force to the brackets which would amplify the forces to the mounting
points on the frame.
Washers: We only use 304 grade stainless
steel in all our slider kits to reduce metal to metal corrosion
and binding.
Frame Slider
Material
Motovation Accessories uses a proprietary
High Molecular Density (HMD) formulation
of nylon. This nylon is impregnated during the extrusion process
with UV inhibitors to resist destabilization of the molecular
matrix
and discoloration
during
prolonged UV
exposure. This formulation is also molybdenum disulfide infused
to give it the same lubricating properties as Delrin. This
formulation is 75%
more
resistant
to abrasion
than Delrin
and
exhibits a
reduced
propensity
to "chunk
off" or "break off" during
extended abrasive events and it's 'slickness' reduces it 'grabby-ness'
during slides that may cause your bike to tumble and cause more
damage.
What about Delrin or ABS? Many frame slider manufacturers
use them because it much softer, much cheaper and easier
to machine,
i.e.
the
material
flakes off readily in
a lathe and is much easier
on the tools. The reason why Delrin is easier to work with therefore
makes it a much less suitable choice than our selection for frame
slider
material. Notice in the pictures on the left that our material
shows stringy edges at the point of abrasion. Delrin does not
do this. It chunks and breaks off on impact much more readily.
Furthermore, Delrin is not UV stabilized and will discolor or
grey in sunlight which will further downgrade it's structural
strength.
