Max Biaggi’s World Superbike colours are to be
offered on a trio of lower capacity bikes including the RS50, RS125 and SR50
scooter for 2010 Aprilia has announced.
The Aprilia Alitalia WSB Racing Team livery has coloured a number of
successes for Biaggi in 2010 and now teen wannabes can mimic the Italian’s
style.
The 200bhp RSV4 Biaggi replica announced in 2010 was the first to bring the
distinctive livery from the racetrack to the street, and these three new
models will broaden the appeal.
Aprilia RS 125 owes much more than its graphics to the race world - it is a
genuine race replica for budding young riders, encapsulating all the
technical expertise of the Noale based marque in the one-eighth litre class.
Over the years, RS 125 has earned a reputation as a benchmark for 2-stroke
sports motorcycles which continues to receive public and critical acclaim in
the most important European markets and is still today the bike of choice
for riders competing in Sport Production races. Confirming this remarkable
success, in 2009, the Aprilia RS 125 was voted Bike of the Year in its
category by the magazine "Motociclismo" and nominated Best 125 of 2009 by
the specialised magazine "In Moto" following a referendum held among the
readers of 12 specialised publications representing 12 European nations.
Aprilia RS 125 boasts class beating componentry and mechanicals, such as the
powerful and reliable single cylinder two stroke engine which, over the
years, has earned a reputation of being unbeatable in terms of both
performance in the race track and reliability on the road.
The compact, ultralight RS 125 is a concentrated package of sophisticated
technology: the frame and swingarm are both derived from Moto GP experience
and made from ultra-stiff aluminium. An upside down front fork, the front
brake with radial calliper with four, horizontally opposed pistons and the
wheels with split spokes are testimony to the bike's overtly racing
character. Other unique features for the RS 125 include an analogue/digital
instrument panel complete with multifunctional computer, a forged steering
yoke and an oval racing silencer with riveted end caps.

The mean, cutting edge look of the new RS 125 tells you that this is a
professional racing machine. The styling of the RS, like that of all Aprilia
sports bikes, is the result of painstaking aerodynamic research.
The fairing, for example, was perfected by extensive wind tunnel testing, to
guarantee great wind protection and minimum drag for maximum racetrack
efficiency. The fairing, windshield and tail not only look mean and
aggressive, but allow the RS 125 to reach a blistering top speed,
eliminating all turbulence around the rider and allowing man and machine to
become one.
The latest generation twin halogen headlight also adds to the mean look of
the new RS 125, and delivers a high power light beam for enhanced visibility
and safety at night. The sleek tail looks exactly like the tail of a GP
racer. Thanks to the effort put into the design of the RS 125’s tail, not
even the passenger seat disturbs the bike’s impeccable lines.
The crossed spoke wheels are not only lighter and more stylish, but safer
and more reliable too.
The powerful but reliable, single cylinder, two stroke, Rotax-Aprilia engine
needs no introduction. Over the years it has won a reputation for being
unbeatable on the track and dependable on the road.
Still today, this engine boasts technical solutions that are
state-of-the-art for two strokes, including a crankcase reed valve intake,
liquid cooling, an anti-vibration balancer shaft, and an automatic mixing
system. The RS 125’s engine has been constantly updated over the years to
keep in line with the latest emission control legislation without penalising
performance. A catalytic converter and precision carburation has won
Aprilia’s single cylinder two stroke homologation to Euro 3 standards. And
the amazing thing is that this has been achieved without losing out on
performance: the Aprilia RS 125 engine remains the reference point for all
125 cc powerplants.
Without a doubt, the most advanced single component on the RS 125 is its
frame. Developed from Aprilia’s vast experience in GP 125 racing, the RS 125
frame is made from cast aluminium alloy with cross-ribbing reinforcement.
Despite its extremely light weight, this advanced structure achieves amazing
torsional rigidity, setting the standards for Aprilia’s competitors.
The box section, aluminium alloy swingarm has the highest torsional rigidity
of all production 125 cc swingarms. Differential side members enable the
exhaust to follow a path that maximises engine performance and enables more
acute angles of lean to be achieved on bends without risking dangerous
contact with the asphalt.
The suspension too plays a fundamental role in ensuring not only the RS 125’s
performance, but its safety and comfort too. The RS 125 can rely on an
upside-down fork that has been optimised for maximum performance on the
racetrack while also delivering a more satisfying ride on public roads.
The rear suspension features rising rate linkages based on Aprilia’s 125 GP
racing technology, for excellent traction and superb comfort even over
uneven road surfaces. The hydraulic monoshock that provides the damping for
the swingarm is also adjustable in spring preload.
Like any self-respecting supersport motorcycle, the RS 125 has to have the
best when it comes to components. The braking system is the best available,
and designed for maximum efficiency under competitive riding conditions. The
front brake is a genuine state-of-the-art, high performance system with a
radial caliper and four opposed pistons. In addition to the 320 mm front
disc, the system also incorporates a radial master cylinder and aeronautical
hoses for maximum precision and unrivalled braking power. The rear disc is
220 mm in diameter and is also equipped with metal braided hoses for
perfectly balanced, high performance braking.
The Aprilia RS 125 is packed with prestige components. Compact and
impressively light in weight, the instruments include an analog rev counter
and a multifunctional digital display with an on-board computer that can be
operated from the handlebars. The speedometer, rev counter, coolant
temperature gauge and exclusive racing chronometer put you in total control.
The on-board computer even has provision for interfacing with the optical
finishing systems used on racetracks.
"As you accelerate the Single seems to gain momentum in protest. But as the
rpms progressively increase, the engine begins to spool up quicker. That
glorious 2-stroke “braappp” matches engine speed and as soon as the
crankshaft spins to that magic 10,000 rpm, the engine springs to life and
finally rewards its riders with some decent acceleration." – motorcycle-usa
"If you are of normal size and keep the little engine singing in its sweet
spot, she has plenty of juice to see triple-digit speeds and embarrass
riders on liter-bikes in the tight stuff. Top speed attained at MSR Houston
was an indicated 108mph on the longest straight and still pulling;" –

"The Aprilia RS125 is probably one of the best handling bikes on the planet.
Its able chassis can easily cope with double the power. The Aprilia RS125’s
brakes are astonishing, particularly so on the 2006-onwards motorcycles,
which boast a sexy radial caliper up front, and the forks are beefy 40mm
items for greater control." – MCN
The Aprilia RS 125 can mark the beginning of a beautiful friendship between
young riders and supersport bikes in general as the small two-stroke blast
has all it takes to make one fall in love with quick acceleration and sharp
handling, all in a user-friendly manner
