The RSV4 was unveiled on 22 February 2008 at the International Piaggio Group Convention in Milan. Production began that same year. The engine displacing 999.6 cc was a 65-degree V4 configuration, chosen as a departure from the V-twin architecture that had powered Aprilia's previous flagship, the RSV Mille and RSV 1000 R. Aprilia stated that the engine was developed specifically for superbike competition, with factory race specification targeting over 200 horsepower. The street-legal version carried an electronics package called APRC (Aprilia Performance Ride Control), encompassing traction control, engine brake control, wheelie control, and launch control.
From 2021, the engine displacement was increased to 1,099 cc, raising maximum power to 217 hp at 13,200 rpm and peak torque to 125 Nm at 10,500 rpm. The updated RSV4 1100 range includes the standard RSV4 1100 and the RSV4 1100 Factory, the latter adding Smart EC 2.0 electronically managed Öhlins front fork and TTX rear monoshock alongside forged machined aluminium wheels.
In 2009, Aprilia's first full season of World Superbike competition with the RSV4, Max Biaggi reached the podium nine times and claimed a race victory at Brno. The following year, 2010, Biaggi won the Superbike World Championship, giving Aprilia its first title with the V4. He continued racing the RSV4 and delivered a second title for the bike in 2012, ending his career with that championship.
Sylvain Guintoli won the 2014 Superbike World Championship for Aprilia riding the RSV4, adding a third manufacturers' title across the model's racing life. Lorenzo Savadori won the 2015 FIM Superstock 1000 Cup season on the same platform. In the 2012 and 2013 MotoGP seasons, RSV4-derived machinery was used by Aspar Team and Paul Bird Motorsports, with the bikes finishing 11th and 12th in the constructors' standings in their respective years.
The initial range offered the RSV4 Factory as the higher-specification model and a limited RSV4 R edition restricted to 350 units.
For 2016, Aprilia introduced the RR and RF variants to align with revised World Superbike technical regulations that permitted fewer modifications to production machinery. The updated bikes were lighter, more powerful, and carried improved handling and electronics compared to their predecessors.
In 2025, Aprilia Racing launched the RSV4 X-GP, a limited edition of 30 units produced to mark the tenth anniversary of the RS-GP's debut in MotoGP. It uses the 1,099 cc V4 producing 238 hp and 131 Nm of torque, managed by Aprilia's APX Racing electronics platform with gear-by-gear adjustable strategies.
The RSV4 established Aprilia as a consistent championship contender at the highest level of production-based motorcycle racing, a position the brand had not held since the V-twin era. Its V4 engine layout has since influenced broader industry trends in the superbike segment, and the model remains Aprilia's commercial and competitive centrepiece in the 1000 cc class.
