| Notes:
Suspension:
For XC racing we offer narrower a arms. The stock front shocks
have large bodies and large shafts which cause several problems - if
you get them setup that they are plush - they will blow thru the
travel and bottom on big hits. If you set them up so they dont
bottom - they will ride harsh.
For anyone serious about racing this quad you may want to check
out aftermarket front shocks with smaller bodies and smaller shafts
to give you good bottoming resistance while still maintaining a
plush ride.
The rear suspension linkage has a very high progression ratio
which causes harshness toward the bottom of the stroke. Our Econo
link with take some of the progression out and is an excellent link
for MX racing due to the smaller tires and the different needs for
MX - it is also an excellent link for the trail rider who just wants
to lower the quad and soften it.
For the series racer we offer the Pro Dual Link that give an even
greater progression change then we can achieve with one link and
also offers a better leverage ratio. This link however requires a
shorter shock then stock.

We have been developing many new products for the YFZ
450R for both XC racing, MX racing and for the trail rider.

spending a lot of money.

offers a better progression and leverage ratio curve vs. the Econo
link. If we do your rear shock conversion - we modify your rear
shock to accept this link. Please note: This link will not work
with a stock rear shock that has not been modified by us. It will
only be sold to existing customers who already have our shock
conversion or as part of one of our shock conversions.
Engine
Piston
Kit...............................................................................................................................$225.00
This is a custom made piston from Wiseco that gives good
combustion action without having a high compression ratio - it runs
much cooler then many of the high compression pistons available for
the quad. It is the same piston that the Yamaha's Factory
riders were using in 2010 these riders included Thomas
Brown, Bill Ballance, Donnie Ockerman, and Brandon Sommers, Taylor
Kiser, and Walker Fowler. This
Piston is available in both 95 and 96mm.
Camshafts..............................................................................................................................$425.00
These cams have the most average power of any cams I have tested.
If you racing on the dyno only - dont buy these - they do not have
as much peak power as a few others.
Power Commander
(basic)...................................................................................................$349.95
This comes with a custom modified fuel curve for racing. This
comes programmed for your quad. I need to know what exhaust, with or
without air box lid, what cams, what piston, what type of riding,
what altitude, and what fuel you are running.
Outer Sprocket
Guard..........................................................................................................$49.95
You need to run some kind of chain guide with this to ensure that
the chain does not come of to the inside.
Dual Sprocket
Guard...........................................................................................................$124.95
Please be aware that it is possible to get debris trapped in this
setup causing severe engine damage!!
Rotor
Guard..........................................................................................................................$49.95
Note: The installation of this part is critical to the life of
this part and it will wear out very fast under certain riding
conditions. |
