Aprilia RS4 50 Replica
New colours for the smaller sports SBK Aprilia, complete with '33 'Marco Melandri decals. The price unchanged from the base version
After having
announced a
month ago the
new RS4 50
Replica, Aprilia
has come a 'full circle'
of its sport models
dedicated to youth
with the confirmation of 125 cc
variant - faithfully
inspired by the
Aprilia RSV4
SBK 2014 with
which Marco Melandri and
Sylvain Guintoli
defending the colors
of Aprilia
in World Superbike.
As for the engines,
the single-cylinder
50 cc of
the 50 Replica RS4
is a two-stroke
liquid-cooled motor
with valve induction, separate
lubrication mixing and
a six-speed gearbox.
The RS4
125 Replica
is driven by a
single cylinder 125
cc, 4-stroke,
4-valve, electronic
injection and
liquid cooled, with
distribution to
double overhead camshaft
(DOHC).
Extensive aerodynamic studies have minimised surface areas without compromising wind protection, and the fairings showcase the superlative mechanicals of the Aprilia RS4 50 and Aprilia RS4 125 rather than conceal them. As a result, the frame and engine are not hidden away but proudly flaunted as fundamental elements of the design of Aprilia's new small supersports models. With the triple headlight, the Aprilia RS4 bikes have a decidedly aggressive look that lends a unique character to the entire front end. The LED taillight merges stunningly into the ultra-compact tail fairing and offers excellent luminosity. The fairing, product of extensive wind tunnel testing and race experience, offers excellent wind protection together with superb aerodynamic efficiency. And as well as contributing to the extremely aggressive looks of the bike, the top fairing and tail fairing also maximise performance in terms of speed. On Aprilia RS4 125, one additional detail underscores the level of sophistication of the bike: the exhaust, which is unmistakably inspired by competition machines, is completely integrated within the lower part of the fairing. A solution that is not just visually effective, but which also contributes significantly to the dynamics of the bike by helping to centralise masses. With the new RS4 50 and RS4 125, Aprilia confirms its global leadership in the small capacity sports and young-targeted bike segment, creating models that exceed the expectations of even the most discerning rider.
The sophisticated chassis architecture of
the Aprilia RS4 50 and RS4 125 is complemented by state of the
art engines. The single cylinder 50 cc unit developed by Aprilia
for the RS4 50 is a water cooled two-stroke with reed valve
induction. The lubrication uses a separate mixing system with a
variable capacity volumetric pump. The six speed gearbox lets
the rider make full use of the performance of this class beating
engine.
With a six speed gearbox allowing the rider to make full use of the power available in all conditions, the Aprilia RS4 125 offers unbeatable performance in its class not just in terms of absolute power at high engine speeds, but also in terms of usable power band, minimised vibration and outstanding mechanical reliability.
