Aprilia RS125

The compact and lightweight dashboard provides all the functions of a realaprilia rs125 white 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.

Aprillia RS50 Aggressive and Irresistible looks

aprillia rs 50 white

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 youJempol ke atas. 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.

The performance of the RS 50 is kept constantly under control just like that of a racing machine. The instrumentation includes a rev counter, odometer, trip counter, a racing chronometer with a 20 lap memory, and a service indicator.

The RS 50’s aluminium double beam frame features an extruded profile and
internal reinforcement to deliver unrivalled control in bends and amazingly agile direction changes.

The swingarm is a double member, extruded aluminium unit with reinforcement truss and a hydraulic monoshock.

With an ultra-modern two-stroke engine, racing frame and suspension, advanced brakes and racetrack wheels, the RS 50 offers you unrivalled
performance, control and safety. Its ergonomic controls, fuel tank and seat are designed to fit your body; its fairing offers all-round wind protection; its footrests provide the ultimate in support. Only Aprilia can give you so much, plus the prestige of a legendary name.

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.

The RS 50’s radial front brake is powerful and smooth to guarantee maximum active safety.

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.

From 10,000 rpm, the final 2500 rpm in each gear is a heady cocktail of speed, noise and violence mixed with a surreal dream-like sense of tranquillity. Keep the motor spinning hard through the gears along Monza's two big straights, head jammed under the new bigger screen and it's as if you're floating - an incredible feeling. It's only the digital speedo's numbers flickering furiously upwards like a stopwatch and Monza's lush green trees whizzing by you that give you any true sense of speed.

That said, due to the limitations of Monza's straights, the biggest number I saw was 288 km/h (179 mph) before having to brake for (and almost missing, as I was watching the speedo for too long) the tight, first-gear chicane at the end of the start/finish straight.

But what is certain is that the MV engine is a diamond of a thing and its spread of power from low revs to the 13,000-rpm redline impressive. But it does have a few rough edges. The fuelling at low rpm isn't great, and trying to accelerate smoothly out of the first-gear chicane, especially on a damp track in our first session on the bike was a tricky, jerky affair. The gearbox is quite harsh and slow, too, causing crashing through the gears and missing them completely if you're too quick with the lever. On some down changes false neutrals appeared, one notable time braking from sixth to third at the end of the fast straight that leads to the fast Parabolica corner - an early morning eye-opener if there ever was one.

I rode three different R312s and some had better or worse fuelling and gearboxes than others. Some testers had the same problems as me and some didn't - let's hope the set-up of the production models will be more consistent.

Going through corners has always been one of the F4's trump cards. All these MVs have a thoroughbred racebike-feel to them. They're cramped, stiffly sprung and are definitely more suited to the track as they're uncomfortable to ride at slow speeds, but they do get better and better the harder you push them. At a track they're really in their element, as that fastest lap at Masterbike on the F4 1000R proves.

But here at Monza all was not well with the R312 simply because of the way it had been set-up. During our first session the suspension was softened right off and the pressures in the Pirelli Super Corsa tires dropped to cope with the cold, damp track. On these settings the MV gave me a fair amount of confidence to go quickly. But for our second session on a dry track the settings were the left the same and the MV wobbled and weaved in the high-speed corners and needed a Herculean effort to steer through the chicanes - it was like riding on flat tires, which in effect is what I was almost doing.
