Aprilia RS 457 2026 — Specifications

When discussing Aprilia in a bikers' café, the names that always come up are the same: RSV4, Tuono, those four-cylinder powerhouses that make racers salivate and insurers tremble. Yet, Noale has always known how to build something else. The Tuareg, the Dorsoduro, the Shiver, the Caponord, a collection of machines that prove the Italian manufacturer is not just about extremes. And since 2023, there’s the RS 457, a sportbike designed for the A2 license, which is now pushing forward with a GP Replica version seeking to capitalize on the brand's racing heritage.

The Aprilia RS 457 is based on a 457 cc inline twin-cylinder engine with a 270-degree crankshaft, a configuration that gives it a more lively character than a classic 180-degree twin, without the sometimes unpleasant irregularity of a V-twin. Power is capped at 47 horsepower at 9,400 rpm, the legal maximum for the A2 category, with a torque of 44.1 Nm available from 6,700 rpm. The total weight is 175 kg, which places it in a reasonable range compared to a Kawasaki Z400 or a Honda CBR500R. The announced top speed is around 180 km/h; no one will contest that on an open road. What’s more striking is the chassis architecture: a double-spar aluminum perimeter frame, where almost all the competition settles for welded steel tubes. This is a significant argument when discussing Aprilia RS 457 reviews, and purists will appreciate it.

The GP Replica version attempts to ride the tradition of racing liveries that Aprilia has cultivated since the 125 AF1 Reggiani in 1987. The principle is honest, the execution a little less convincing. The paint scheme derived from the RS-GP looks too much like the "Racing Stripes" decoration already offered as standard on the RS 457. The differences exist: a black frame and swingarm, sponsor decals, a seat cover included as standard, but it takes a trained eye to spot them at first glance. It’s not a fatal criticism; it’s simply a commercial reality: the GP Replica sells a dream to those who are willing to believe in it. The Aprilia RS 457 accessories added to this version are more concrete; an up-and-down quickshifter and more aggressive brake pads complement the already correct braking provided by the four-piston Bybre caliper on a 320 mm front disc. Replacing this caliper with a Brembo would have been more spectacular, but also much more expensive.

The onboard electronics deserve attention, because this is where the Aprilia RS 457 A2 justifies its price positioning at €7,500. Three riding modes, traction control, switchable rear ABS, anti-wheelie, a five-inch color TFT screen: we are far from the spartan stripping sometimes inflicted on entry-level machines under the pretext that they are aimed at beginners. The seat height at 800 mm remains accessible for an average build, the 13-liter tank ensures correct range, and the 41 mm inverted fork with its 120 mm of travel offers a healthy base for progression. It’s not a track bike in the sense that a Ninja 400 track-day-ready could be, but it’s a machine that doesn’t limit the rider’s progression.

The target audience for the Aprilia RS 457 2025-2026 is clear: the young A2 rider who refuses to be saddled with a second-rate machine, or the returning license holder looking for a compact sportbike without breaking the bank. For this profile, the RS 457 GP Replica ticks almost all the boxes. The livery being too close to the standard version remains its most obvious weakness. Everything else, the mechanics, the chassis, the electronics, confirms that Aprilia also knows how to build accessible machines with seriousness.
