Limited edition Aprilia RSV4 X Ex3ma – First Look

The Ex3ma is the latest “X” model from Aprilia's Factory Works program, following the RSV4 X, the Tuono X, and most recently, the RSV4 X Trenta in 2022. These limited edition X models all represented the pinnacle of Aprilia’s technology and performance.

Or at least, the pinnacle of what could be made available to the public, behind Aprilia’s MotoGP program. The RSV4 X Ex3ma actually has a direct link to the Aprilia RS-GP 24 bike, incorporating its patented ground-effect aerodynamics. Other sportbikes have incorporated aero elements in recent years, but no production motorcycle has gone as far as the RSV4 X Ex3ma.

Up front, the fairing incorporates a double-winglet design, like many other modern superbikes, but the RSV4 X Ex3ma goes even further with aero elements on the rest of the bike. The swingarm has a scoop-shaped under-wing (commonly referred to as the “spoon”, while the front wheel has further aero elements (Aprilia calls them “cornering wings”) below the brake calipers.

Aprilia claims the winglets at the front of the carbon fiber fairing increase vertical pressure by five-fold on the straights, improving stability and inhibiting wheelies. When leaned over, the design claims triple the downforce, improving grip. The side panels also have a molded shape, with a slight bulge in front of the footpegs. Aprilia says this shape exploits air pressure between the bike and the ground during corners, further enhancing grip.

The Ex3ma comes in a special Perla Nera livery inspired by past Aprilia race bikes, including the RS 250 on which Biaggi captured three world championships from 1994 to 1996.

Beneath the fairing is Aprilia’s 1,099cc 65° V-Four engine, upgraded with a higher compression ratio, a highly permeable Sprint Filter air filter, and augmented by an SC Project exhaust system with titanium headers and twin silencers (styled after the RS 250's exhaust). Aprilia claims a peak output of 230 hp at 13,500 rpm (just short of the 13,900 rpm rev limit) and 97 lb-ft. at 11,000 rpm.

The electronics package is based around Aprila’s APX racing ECU, the latest evolution of the system used in its World Superbike program. The GPS-backed APX system precisely calibrates the power delivery, wheelie control, traction control, and engine braking for each gear. Riders can adjust these parameters on the fly, using a dedicated button, or during setup when connected to a laptop (which comes included with the RSV4 X Ex3ma).
