Aprilia RSV4: Biaggi Superbike Replica

Biaggi Superbike

For those ready to take that next step in racing, the Italians at Aprilia just released the RSV4 Biaggi Replica, a true "race-ready bike into which the knowledge, technology and research capability of the Noale Racing Division are condensed."

And what could be a better time, considering Aprilia is riding the success of Max Biaggi’s double World Superbike win at Monza this weekend, his second double since Portimao. The RSV4 Biaggi Replica is the sister machine to Biaggi’s actual Superbike, and features 200 hp, this track version producing 20 hp more than the street version, and weighing around 386 dry.

Gigi Dall’Igna, technical and sport manager of Aprilia Racing, says "With the RSV4 Biaggi Replica we offer the sports enthusiast a motorcycle which is as close as you can get to the RSV4 that Max rides on the track in World Superbike. In this project, which was developed in parallel to our re-entry into SBK, we poured out all of our knowledge and years of experience on tracks all over the world. This is the bike which came out of it, conceived and developed within Aprilia Racing to offer unique sensations to the shrewd user."

The RSV4 Biaggi Replica features a 65-degree V4 with Weber-Marelli throttle bodies, two injectors per cylinder, adjustable height intake ducts and ride-by-wire throttle. The power of V4 is channeled to the track through an extractable six-gear transmission with a multi-disc bath clutch and mechanical anti-skipping system. It also features a 4-2-1 titanium sport exhaust with a single-side silencer in carbon and titanium.

When it comes to chassis, adjustability is key for tailoring a machine to every rider’s unique settings. The Biaggi Replica has an aluminum double rail frame with cast and pressed elements featuring an adjustable headstock position and angle, engine height and swingarm pin height.

As for suspension, found out front are an Ohlins fork with 43mm stanchions and tin-surface treatment, adjustable pre-charge, compression and extension. Out back is an Ohlins TTX36 mono-shock absorber with adjustable in spring pre-charge, offset, compression and extension with dedicated calibration. The suspensions operate via a progressive APS linkage.

Regarding electronics, the Biaggi repli-racer is loaded with the latest technology, including a digital APX on-board computer that uses advanced vehicle management strategies including: TCS traction control, QuickShift assisted shifting, Antibacklash system, engine brake and pit lane speed limiter. All the parameters of these gizmos can be modified with a push of a button on the handlebar or dedicated "Aprilia Racing Palm."

Stopping power is provided by Brembo, with radial attachment single body calipers and sintered pads that operate on 320mm front floating disks. To save weight, the system utilizes a lightened stainless steel braking surface and a flange in aluminum.

Where this power meets the pavement you’ll find radial Pirelli Diablo SBK tires, 120/75 on the front and 190/65 on the rear, wrapped around Marchesini forged magnesium alloy wheel rims with a seven spoke design and "anti slip" treatment.

Regarding looks, the RSV4 Biaggi Replica is available in the Alitalia livery of Biaggi’s machine, or a carbon look, and can be used as an entry level for the SBK class in accordance with FIM regulations.

And as expected, with such elaborate technology comes a hefty price: the RSV4 Biaggi Replica has a base price around $64,000 at the current exchange rate (50,000 Euro).
