SUZUKI RM-Z250 AND 450 YOSHIMURA PERFORMANCE PACKAGE
PRODUCT REVIEW
P72
If weight is a concern for you,
then the high-priced lighter tita-
nium/carbon fiber RS-4 exhaust
system is probably the way to
go - it's about a pound and a half
lighter than the RS-4 steel system
according to Yosh's figures. For
our test bikes, though, we went
with the package with the most
overall value – option two, which
comes with the heavier (though
still lighter than stock) stainless
steel/aluminum system and all
the knick knacks that go along
with it, including full graphics.
Installation is easy (we did it at
the track) and takes less than an
hour to install per bike. Most of
that time is spent on the graphics
kit. That factory look when you're
done, however, is well worth the
effort.
The exhaust system mounts
right up nicely using the stock
bolts. A rubber grommet and an
aluminum spacer are included in
the kit for the narrower-than-stock
muffler. Overall, the Yosh exhaust
system is extremely well built and
looks pure factory. It's a serious
piece of racing equipment.
The muffler comes with an
AMA-approved sound insert that
we chose not to run at the track,
yet the Yosh pipe didn't sound
significantly louder than the stock
Basically, for $600, your new Suzuki
RM-Z450 could look like this if
you opt for one of the Yoshimura
performance-package incentives
from Suzuki.
