Over four pounds lighter
than the stock muffler
RIDER AN ALYSIS
The Yoshimura RS-4 slip-
on provides a claimed 6%
increase in peak torque
and horsepower over
stock but that is not the
primary reason we chose
to change out the stock
system. Removing 4.5
pounds of f a 533-pound
motorcycle is also not
something you are likely
to notice, but taking that
weight of f the rear of
the bike couldn't hurt.
The stock Africa Twin
exhaust and large heat
shield looks like a boat
anchor on the back of an
otherwise clean looking
bike and that is the
primary reason we chose
to install the Yoshimura
RS-4 exhaust.
The RS-4 does provide
a little better exhaust
note on the Africa Twin,
even with the optional
quiet insert installed. The
stainless steel, "Works"
finish canister and carbon
end cap look great and
have held up well. We
have put over 2000 miles
on the bike since mount-
ing up the Yosh exhaust
and it still sounds just as
good as the first day we
installed it.
