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.
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.
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 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.
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.
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.
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.
