Not content with upgrading the roadgoing RSV4 Factory, Aprilia are celebrating a decade of V4 production with an exotic, track-only derivative, the RSV4 X, of which just ten units will be produced.
The 1078cc V4 engine is hand built by Aprilia’s racing division with new Superbike-style intake cams and buckets, MotoGP-type air filter and Akrapovic exhaust with titanium manifolds, boosting peak output by 8bhp to 222bhp. The X-bike also gets an ANN (Aprilia No Neutral) gearbox, with neutral below first, as developed by the race team for faster shifting and reduced upshift errors.
Chassis mods are mainly aimed at reducing weight, including carbon-fibre fairing, plus billet aluminium parts including clutch lever, sump guard and adjustable footrests. Brembo’s GP4-MS brake calipers are operated by a machined-from-solid pump. Forged Marchesini wheels, which hold Pirelli slicks, contribute to the 12kg lower dry weight of 165kg. Electronics are adjusted by a racing-derived push-button panel.
With no race championships for it to enter, the RSV4 X is a truly special track day special. It costs €39,900 (roughly £34,000), which is a fair chunk of change, but not too unreasonable when stacked up against some of the other high end superbikes on the market. Fancy one? They can be ordered online from late April, via www.factoryworks.aprilia.com. Buyers have the option of collecting it from Noale and getting a tour of the race department too.
