2010 Aprilia SX - RX 125
 
It was inevitable that the innovative
SXV and RXV would extend their influence to other
members of the Aprilia range sooner or later. The
world-beating styling, performance and technology
of these fantastic machines has engendered a family
of eye-catching and modern off-road motorcycles. The
SX 125 and RX 125 are the latest off-road machines
from Aprilia. Specialist and refined, they are the
obvious choice for young riders who want to stand
out right from the very start.
The SX and RX are both built to deliver total rider
satisfaction. Though the technology is basically the
same, it has been adapted to match the different specialities.
The SX and RX share the same body, frame, engine and
suspensions but have very different characters for
very different passions.
With its 17” wheels and sports tyres, the SX
is the obvious candidate for the prize of the meanest
125 over mixed routes. Nippy and lightweight, the
SX delivers real ‘big bike’ performance
without exceeding the power restrictions imposed by
law. Its refined, sprightly engine never lets you
down.
The RX and the SX 125 also share a clear Aprilia family
look, obviously inspired by their bigger sisters,
machines that have established a whole new trend in
off-road design.
Styling
Aprilia was the first manufacturer to introduce dramatic
innovations to the designs of essential enduro and
motard motorcycles. In the same way in which the RXV
and SXV have become style icons in their own right,
the SX and RX are destined to leave their mark on
young off-road riders.
As with all off road motorcycles worthy of respect,
the SX and RX are built for maximum functionality
and efficient riding and control. Their styling leaves
no room for pointless frills and gadgets. The unmistakably
pure lines of the SX and RX are simply unique among
off-roaders.
Engine
The single cylinder unit that powers these Aprilia
125 cc motorcycles is a state-of-the-art two stroke
engine. It is a classic example of how race-developed
technology can deliver extremely low emissions as
well as top performance. On the RX 125 and SX 125,
Aprilia has succeeded in perfecting its two stroke
design to bring it in line with the strict new Euro
3 standard without any loss of performance or riding
satisfaction. This sparkling single cylinder engine
easily develops the maximum permitted power for its
class, with all the lightness and zippy acceleration
typical of a high performance two stroke.
This engine has already established a place for itself
in the hearts of 125 fans, thanks to its many advanced
characteristics, including liquid cooling, and a balancer
shaft. The cylinder has a nickel silicon carbide (Nikasil)
liner for an ultra-reliable, extended life. Lubrication
is provided by a separate mixer system.
Brakes and Suspension
Active safety on the Aprilia RX and SX is ensured
by advanced suspension and a braking system that sets
new standards for stopping power and progressive action.
The front brakes feature a 260 mm disc and two-piston
floating caliper while the back brake incorporates
a 220 mm disc and another floating piston.
The robust, steel, double cradle frame is coupled
to an over-sized suspension system. At the front is
a mighty, 40 mm upside down telescopic fork offering
wheel travel of 260 mm.
At the back, a long steel swingarm delivers maximum
traction and a rear wheel travel of 270 mm.
Wheels
Specialist motorcycles like the RX and SX demand
top level components, especially wheels, the strength
and lightness of which are so important to handling.
The Aprilia RX and SX are equipped with prestigious
spoked wheels with new black anodised rims. Just like
top sports motards, the SX boasts lightweight 17 inch,
wide profile wheels and generous sports tyres, 110/70-17”
and 150/60-17” for maximum grip under all conditions.
Instruments
To confirm its determination to build advanced motorcycles
that are versatile and practical in everyday use,
Aprilia has equipped the RX and SX with sophisticated
digital instruments just like those on the bigger
SXV and RXV.
Once again Aprilia motorcycles are going to feature
in the dreams of young riders.
