RACE-WINNING AGILITY
The RS 125’s sophisticated and lightweight frame is developed
from the superb racing frames of Aprilia’s amazing 125 GP bikes.
Made from polished aluminium alloy, it guarantees extremely high
torsional rigidity, and delivers maximum control and agility under
racing conditions.
GP SWINGARM
One of the most prestige components
on the new RS 125 is its die-cast
aluminium alloy swingarm. In addition
to guaranteeing the highest degree of
torsional rigidity of any production 125,
the swingarm’s special design also lets
you lean further than ever on the track
without touching the asphalt.
ADVANCED AERODYNAMICS
With its aggressive, penetrating and exciting design, the RS
125 instantly expresses all your desires for victory. Its sleek
lines are the result of the latest aerodynamic developments
and extensive wind-tunnel testing. The RS 125 offers unrivalled
protection against turbulence. In fact, everything about it, from
its nose fairing with latest generation twin headlights to its
mean-looking and streamlined tail with integrated seat and
powerful rear lights is designed to offer minimal resistance to
the air.
POWER AND RELIABILITY
The famous liquid cooled, single cylinder, two-
stroke engine that drives the RS 125 sets the
standard for 125 cc powerplants. Derived from
Aprilia’s vast competition experience, it is reliable
on the road and powerful on the track, thanks to
refined technical solutions like reed valve induction
in the crankcase and an anti-vibration countershaft.
And of course it is homologated to Euro 3 standards
for maximum performance plus respect for the
environment.
RACING INSTRUMENTATION
The compact and lightweight dashboard provides all the functions of a real racing unit. It includes an analogue
rev counter and a multi-functional digital display with handlebar controls to access tachometer, trip counter,
battery voltage meter, clock and 20 lap timer, coolant temperature gauge and fuel reserve indicator. The unit also
incorporates provision for interfacing with a racetrack finish line timing system.
COMFORT AND SAFETY
The upside down fork and rear suspension with rising rate linkages guarantee the highest levels of handling,
safety and comfort, both in everyday traffic and on the racetrack. Even the brakes represent the best the market
currently has to offer. The radial front caliper is a four piston unit and is coupled with a metal braided brake hose
and a 320 mm floating disc. The rear brake also combines with a 220 mm disc and metal braided brake hose.
The result is precise, balanced and powerful ‘GP’ style braking.
RACING WHEELS
The ‘Y’ spoke alloy wheels have six spokes at the front and five at the rear. These low weight, high strength
wheels are fitted with tubeless radial tyres for unrivalled agility and superb road-holding under all conditions.

THE MOTORCYCLE OF TOMORROW’S CHAMPIONS. If you’ve always dreamed of
lining up on a GP starting grid, and leading the field on a true supersport, then the RS
50 is the bike for you. Its technical solutions come directly from the pits of the MotoGP
World Championship. In fact, everything about the RS 50 is derived from the Aprilia’s
2008 World Champion 125 and 250 GP bikes. Its sleek, aggressive and irresistible looks,
for example, are designed for maximum aerodynamic penetration. So stand out from the
crowd on the RS 50: the bike of tomorrow’s champions.
RADIAL CALIPER
The RS 50’s radial front brake is powerful
and smooth to guarantee maximum active
safety.
RACING EXHAUST
The under-seat exhaust ensures perfect
balance and makes a major contribution
to the bike’s exceptional, aerodynamic
form. The system is manufactured using
racing technology to ensure maximum
power output.
LIGHTWEIGHT WHEELS
The ‘Y’ spoke wheels feature the same
design as those fitted to Aprilia’s GP
bikes. Lightweight and balanced for
stability in bends, these wheels are
specially designed for use with the latest
generation of radial tyres.
