QUICKSPIN I 2021 APRILIA RS 660
These electronics are even more advanced than
the RSV4 1100 Factory's and allow the rider to dial
in just the right amount of engine brake to pull the
machine into the apex of the corner. You can go
from almost no engine brake, so you can ride it
like a two-stroke with massive corner entry speed
to full four-stroke. Then you've got the beautiful
Aprilia Traction Control (ATC) system, variable
to eight different levels, so you can hammer the
throttle on corner exits with all the confidence af-
forded to machines in the superbike class. This is
a considerable advantage over any other machine
currently in the Twins Cup category.
Then you've got that engine. What can you say
other than this is simply the new benchmark in the
Twins Cup? With about 85 horsepower at the tire
(depending on the dyno operator), the Aprilia simply
walks away from its competitors and isn't that far
off what a stock, four-cylinder super-
sport machine produces. You've
got five variable engine levels with
the APRC system, but you'll want
to put it into the Challenge mode,
where you get the closest 1-1 con-
nection with the throttle to what
you'll get at the tire.
We're pretty
sure we got all
the colors of the
rainbow here.
Quickshifter is
standard fitment
on the RS 660—a
first for the class.
You'll want some
sturdier rearset
footpegs if you're
going racing,
though.
