Aprilia has unveiled a new, track-ready version of its hugely successful RSV4 to celebrate 10 years of production; the RSV4 X. As part of the 2019 Aprilia All Stars event at Mugello, Aprilia unveiled a track-only version of its RSV4 sportbike; the 225hp X. has been tailor-made by Aprilia Racing – and if you delve into the bikes technical specification, it’s obvious that it’s serious about its performance on track. The bike is the creation of Aprilia Racing and makes use of a selection of lightweight components, including a carbon fairing, a lightweight fuel tank, a billet aluminium clutch lever, front brake lever guard, engine sump guard, adjustable foot pegs, upper steering plate and Marchesini forged magnesium wheels. All in this extensive weight saving programmer means the bike weighs just 165 kg. The RSV4 X is powered by a hand-built 1100cc V4 engine that’s been breathed on by Aprilia Racing and boasts new intake camshafts, new valve return springs and caps and new convex bucket tappets. The bike comes with a titanium Akrapovic exhaust system, a MotoGP-spec air filter and it receives an ECU map complete with dedicated track settings. It’s also equipped with the ANN (Aprilia No Neutral) system – essentially a gearbox with neutral positioned below first gear that speeds up shifting from first to second and prevents any up-shifting errors. It’s another clever piece of technology derived from Aprilia’s experiences in WSBK and MotoGP. Brembo GP4-MS callipers complete the factory feel. Just ten Aprilia RSV4 X bikes are available, priced at 39,900 Euros. The new RSV4 X can be reserved online during the second half of April.
