Moving around on the YFZ450 is way different,
and the fenders are not as comfortable as the
YFZ450R, and the seat is narrower and stiff,
making for a rougher ride compared to the YFZ450R
with it new t-shape seat. Also,the Pro Taper
handlebars are a nice feature on both machines,
but the adjustable stem mounts is a noticeable
improvement on the YFZ450R. Also on the YFZ
it feels like you are riding on top of the ATV,
whereas on the YFZ450R I felt down lower and
more comfortable and in control.

focused on improving the ergonomics of
the YFZ450R by narrowing the front of
the seat and increasing the width in the
rear of the seat, which creates a t-shape
similar to what you find on the Suzuki
LTR450. The new seat design improves rider
comfort and allows the rider to more easily
move around on the seat. Also, the fender
panels are now flex and provide grip for
improved rider comfort |

| The
key switch of the YFZ450R
ATV has been relocated up by the dash
indicator lights, which elminates the
chance of turn the key off with your knee
while riding as on the YFZ450 |
Turning the key on is a little different on
the two models as well. On theYFZ450R, the key
is relocated on dash up where the neutral light
is on the YFZ450. The new key location also
allows for quicker fender removal with just
four bolts, which makes it more convenient.
Also, the rear fenders have fewer bolts and
there is no need to remove the battery anymore
to get the fenders off on the new YFZ450R as
well. This will make washing up after a muddy
race a breeze!
The engines on the two quads are way different
as well, but without any mods, they felt about
the same. The YFZ still features a FCR style
carb, which a lot of people like, because they
are more familiar with tuning it. However, the
EFI has a noticeably quicker throttle response.
Also nice about EFI is no need to “re-jet”
for minor aftermarket mods or altitude changes.

| The
YFZ450R
engine looks fairly similar to the YFZ450
from the exhaust side, but from the shifter
side, the changes become much more apparent,
and they are significant. The YFZ450R
has an all new titanium 5-valve cylinder
head, crankcases, gear ratios, crankshaft,
to just name a few of the internal changes.
Also, the oil tank and passages have been
relocated. The oil tank is now attached
to the engine for easier maintenance &
quicker engine removal. Also, the starter
has been relocated to the front of the
engine |
I was also able to notice a slight difference
in the gearing. The YFZ450R seems to be geared
a little taller and I think has a higher top
speed. On the YFZ I feel like I am always looking
for another gear.
