Aprilia RSV4 R Service Manual (2009)

Aprilia introduced the RSV4 R in 2009 as the more accessible road-going version of its new-generation V4 superbike platform. The move was a major break from the RSV Mille and RSV 1000 R lineage, which had relied on a 60-degree V-twin. Aprilia's official brand history identifies the RSV4 as the company's new flagship superbike introduced to the public in 2009, developed with Aprilia Racing specifically to compete in the World Superbike Championship. Piaggio's EICMA 2009 announcement then presented the RSV4 R as a 180 hp road model derived from the machine Max Biaggi had already raced successfully in World Superbike.

The defining change was the compact 65-degree V4 engine. Factory specifications give 999 cm³ displacement, a 78 × 52.26 mm bore and stroke, 13:1 compression, double overhead camshafts and four valves per cylinder. Electronic injection uses two injectors per cylinder and four motorised 48 mm throttle bodies, with Ride-by-Wire control, selectable mapping and provision for variable-length intake ducts. A mechanically controlled wet multi-plate clutch incorporates anti-judder and slipper functions, while a six-speed cassette-style transmission and 16/40 chain final drive complete a package conceived as a narrow-V4 litre-class superbike rather than an evolution of Aprilia's older V-twin engine layout.

The chassis followed the same clean-sheet approach. An aluminium dual-beam frame made from pressed and cast elements was paired on the R with a fully adjustable 43 mm Showa upside-down fork and a Sachs piggyback rear shock working through Aprilia's progressive APS linkage. Factory dimensions list a 1,420 mm wheelbase, 847 mm saddle height, 120 mm front travel and 130 mm rear wheel travel. Braking uses twin 320 mm floating front discs with radial four-piston monobloc calipers and a 220 mm rear disc. This specification allowed the R to retain the core frame, braking architecture and V4 character of the more exclusive RSV4 project while using a less costly suspension package.

The RSV4 platform immediately became central to Aprilia's racing identity. Max Biaggi took the RSV4's first World Superbike victory at Brno in July 2009, and Aprilia's official history records the 2010 World Superbike riders' and manufacturers' championships as the platform's first major world titles. The road range then evolved rapidly. Piaggio's 2011 RSV4 R APRC release documents the next major step, adding Aprilia Performance Ride Control with traction control, wheelie control, launch control and quick shift while retaining the basic 65-degree V4 and aluminium-frame concept.

This listing corresponds specifically to Service Station Manual 895777, copyrighted 2009, for the RSV4 R. It covers scheduled maintenance, troubleshooting, electrical diagnosis and wiring, engine removal, complete internal V4 overhaul, fuel injection and Ride-by-Wire systems, suspension, chassis, brakes, cooling, bodywork and pre-delivery procedures. The publication contains no model-year application table extending into later years, so catalog applicability remains restricted to 2009. Related documentation is grouped in the Aprilia RSV4 R manual category.
