Intro

Aprilia RSV4 X-GP arrives as a headline tribute to Aprilia Racing’s decade in MotoGP. It’s loaded with prototype-grade aero and electronics, and it’s built in extremely limited numbers. Why it matters: the Aprilia RSV4 X-GP channels RS-GP25 know-how into a 238 hp, 165 kg package built for lap times, not license plates, with only 30 units to be made.

MotoGP tech, people-first gains

Aprilia has ported over aero from its RS-GP25 race bike, including leg wings, tail wings, and ground-effect fairings. This design increases stability under braking and adds downforce when leaned over, giving the rider more grip and confidence. Aprilia claims up to 5 times the vertical load on straights and 3 times at cornering vs the production RSV4, so the front stays planted and reduces wheel lift when pushing hard. A carbon seat support from PAN Compositi reduces weight and stiffens the rear, so more feedback when loading the tire on exits – that’s where it shines on a flowing circuit.

Engine and performance headline

Aprilia’s 65° 1,099 cc V4 is reworked to a claimed 238 hp and 131 Nm, paired with an STM dry clutch and SC-Project twin titanium pipes for sharper track responses. The APX racing ECU gives you granular control of traction, engine braking and power per gear – handy when dialing in for different track surfaces or temperatures in a single test day. Tipping the scales at just 165 kg, the RSV4 X-GP’s power-to-weight ratio is truly MotoGP-like. This is a genuine Factory Works experience for privateer riders and collectors.

Chassis, brakes, and tires

Öhlins mechanical suspension (with pressurized fork) meets a double-cradle aluminum frame, so you can fine tune without the complexity of factory electronics. Brembo GP4 MS billet calipers on 330 mm T-Drive rotors with Z04 pads give repeatable race braking, while magnesium Marchesini wheels and WSBK-spec Pirelli slicks (125/70 F, 200/65 R) keep unsprung weight low and grip high – essential for late braking passes. This isn’t just a display piece; it’s a track-only machine built to withstand serious lapping, provided you follow the right maintenance and data plan.

Price, build numbers, and availability

With only 30 units being made, this is Aprilia Racing’s most extreme customer-facing package to date. The list price is €90,000 before taxes, putting it in line with previous X-series bikes. Delivery is through Aprilia Factory Works, build-to-order and race-prep oriented, so it’s a collectible, usable tool for advanced riders and teams.

Closing

For collectors and track addicts the Aprilia RSV4 X-GP is a rare glimpse into RS-GP25 thinking – expensive yes, but purpose-built and hard to ignore if you want to get tenths with factory aero and control.

FAQs

Is the Aprilia RSV4 X-GP road legal?
No – this is a track-only motorcycle delivered via Aprilia Factory Works, focused on racing and private test use rather than registration and homologation.

What makes its aerodynamics different from regular superbikes?
Leg and tail wings plus ground-effect fairings add significant downforce in straights and at lean, claimed at up to 5x vertical load on straights and 3x at cornering versus a standard RSV4, improving stability and grip.
