An RSV4 with MotoGP levels of aero, including the under wing.

To celebrate 30 years since Aprilia won its first world championship title, Aprilia (or, more appropriately, the racing division) is introducing this, the RSV4 Xtrenta. Encompassing the same basic profile the RSV4 has carried since its birth over a decade ago, the Xtrenta is defined by the level of aerodynamic work the Noale factory has applied from its MotoGP program.

Since aero is the hot topic in MotoGP racing today, let’s start there. The XTrenta sports the huge front wing just below and beside the nose that has become so commonplace lately. Interestingly, Aprilia claims this wing not only creates more downforce for the front wheel but also reduces drag at the same time.

Look a little closer and you’ll see the attention to aero also applies to the rear of the motorcycle, as the RSV4 XTrenta is the first production bike in the world to incorporate the “under wing” onto the swingarm. Racing fans may remember the under wing was actually introduced by Ducati, circa 2019. Despite the numerous raised eyebrows claiming the under wing would provide an unfair (possibly illegal?) aero advantage, Ducati outwardly claimed the wing was used to distribute air to the rear tire to help keep it from overheating. While nobody really bought that excuse, the wings stayed for that year and all the other manufacturers followed suit. Ironically, Ducati (and most of the other teams) no longer uses the under wing anymore.

Coming back to the XTrenta and its aero efficiency, Aprilia says its “aerodynamic load” has now increased 25% while drag has been reduced 4%. That’s impressive. As for the rest of the bodywork, the carbon fiber pieces are produced by PAN Compositi, using the same processes used in making MotoGP fairings.

The RSV4’s intoxicating V4 engine isn’t left alone either. It now reaches a claimed peak of 230 horsepower, due in part to a higher compression ratio, titanium and carbon exhaust from SC Project made specifically for this bike, and a Sprint Filter air filter. A full titanium, MotoGP-style exhaust will be available as an option.

A revised Magneti Marelli control unit handles the electronic calibration, and the transmission gets a titanium sprocket from PBR. Navigating the XTrenta’s electronic suite is done via the JetPrime racing panel, while Spider provides the accessory pegs, bars, and CNC fuel cap.

On the chassis and suspension side, you expect to see nothing but the best components and the RSV4 delivers. Öhlins suspension keeps the bike planted at both ends, but the internals have been modified by Andreani in collaboration with Aprilia MotoGP engineers.

More top-shelf items include the Brembo braking system, consisting of GP4-MS billet monobloc calipers and 330mm T-drive discs up front. The forged magnesium Marchesini M7R GENESI rims fit Pirelli Diablo SBK slick tires in sizes 120/70 and 200/65, with SC-1 compound front and SC-X compound rear. The wheel weight reduction is around 2 kg compared to the standard.

The livery of the new Aprilia RSV4 XTrenta is a very similar one used by Lorenzo Savadori in the Austrian GP and represents a contemporary interpretation of the one Aprilia sported in 1992 in the 125cc MotoGP class, when it won its first World Title.
