Motorcycle specifications ApriliaRS4 125 2013 New generation

with its RSV4 profile, the 125 RS4 is one of the most attractive 1/8th-liter sports bikes on the market. The 2013 version add an extra touch of sportiness, with a sweet racing flavour. For the first time on a production 125, the Aprilia gains a shifter; the rider can now shift gears on the fly, just like in competition. There's also a new SBK replica Biaggi 2012 decal and a new wave-form brake disc, still 300 mm in size. Pirelli Diablo ROsso II are now the original equipment. The price is up by 200 euros.

genesis: Yo. Clearly, this new RS4 is playing it cool and racing, but with cash. This is the 125, the real thing, the RSV4 Replica. And we're not exaggerating. Aprilia's sporty 125 is a true clone of the World Superbike champion. Headlights, fairing, rear mini-strapontin and shortened butt, tank and airbox cover, inverted fork... It's the same. A bike that all youngsters will want to own, and not just them.

compared to the RS 125, whose heart has changed radically, this is a completely different generation. And watch out for shocks - 2-stroke enthusiasts are in for a real treat. The venerable RS 125 firmly defended the bastion of 2-stroke competition, with an engine that wattled hard and crazy performance, enough to disgust a 500. Today, the RS4 is cleaner, consumes less fuel, requires less maintenance, and has a less toxic price tag. Where's the wolf? In the engine. Gone are the ringlinglin , the smoke and the tearing vocals. In there now lives a modern block with fuel injection, double ACT and 4 valves. What does that mean? That means.... Aprilia's new-generation 125 sports bike is powered by a 4-stroke engine. Economy and the environment benefit, and the talent of the group's engine designers should make it fun to use. But no more crazy performance. Like all 4-strokes of this displacement, we're only entitled to the legal maximum of 15 horsepower. It's hard to believe that the most virulent ex-125 on the market (along with the Cagiva Mito) is giving way to a bike with half the power. But don't worry: the mechanics claim to be far more available than most of the mills in the segment, with minimal vibration and reliability to match.

but don't worry, you'll be able to get the most out of your drums with the chassis underneath. First of all, an aluminum perimeter frame with spars incorporating reinforcing ribs. A 41-mm fork in the noggins, inverted for rigidity. Braking is right up there with the 125s: a 4-piston radial caliper on a 300 mm-diameter disc. The racing spirit is present throughout, with an asymmetrical swingarm, an exhaust well tucked underneath to lower the center of gravity and clear the rear end, and digital instrumentation modelled on that of the V4 hypersport. With tires scarcely wider than an iPhone (*), the machine twirls from one bend to the next with the speed of a beep-beep chased by a coyote.
Once you've put it on the stand, the hardest part will be turning down the invitations to ride offered by owners of R1s, CBRs and other hypersports, as many would swear they're looking at an RSV4 1000.
