On the heels of its uber exclusive RSV4 X winged wonder, Aprilia announced a naked version with the Tuono V4 X. As with the RSV4 X, the Tuono version is designed only for track use and will be produced in very limited numbers. Only 10 units of the RSV4 X were made, and all were scooped up in a few hours after online orders were opened, but Aprilia hasn’t announced how many Tuono V4 X models will be made. We do have a price: 34,000 euros, or about US$40,473.
The most striking detail about the Tuono V4 X (except, perhaps, the black/red/yellow/lavender/white color scheme inspired by the 2006 RSV 1000 Bol d’Or racebike) is the addition of the carbon winglets on the front fairing, derived from Aprilia’s RS-GP MotoGP racer. Aprilia claims the aerodynamic appendage increases stability at high speeds and during braking or when cranking open the throttle.
Beyond the wings, the Tuono V4 X’s entire fairings are made of carbon fiber. The clutch lever, brake lever guard, crankcase guard, adjustable footpegs and fuel cap all made from billet aluminum. Add some Marchesini forged magnesium rims and an Akrapovič exhaust system, and the overall claimed dry weight is a svelte 366 pounds, a significant reduction from the Tuono V4 1100 Factory’s claimed 407-pound dry weight.
The engine is derived from the same powerplant in the regular Tuono and RSV4 1100 Factory but the upgraded exhaust and air filter (the same high permeability Sprint Filter unit used on the RS-GP) help bump the engine output by about 4 hp to a claimed 221 hp.
