Unlike its detuned competitors, the V4 is nimble, lightning fast and a bonafide technology tour de force. From its signature Aprilia race bike triple headlight fixed top fairing to its exhaust, this stealth streetfighter shows off its World Super Bike (WSBK) bloodlines at every angle. It is not simply the most powerful naked bike available in the market, it has also been engineered and equipped with the most advanced electronics package available anywhere, Aprilia Performance Ride Control (APRC). The Tuono V4 fulfills the dreams of every motorcyclist who has ever wanted a race bike just to go for a coffee run – without sacrificing riding comfort. Combining the potent performance and race-proven technologies of the WSBK Championship winner Aprilia RSV4 with the agility, responsiveness and riding pleasure of Aprilia's original Tuono 1000 R naked concept, the new Tuono V4 is a true game-changer. Engineered to Astound The Tuono V4's compact 65-degree engine doesn't scream its performance potential – it proves it every second on the road. Extremely compact, the V4 engine is as slim as a twin-cylinder and seamlessly integrated in the Tuono's ultra-compact chassis. Now delivering 167.3 peak hp at 11,500 rpm and equally impressive torque of 82 ft. lbs. at 9,500 rpm, the V4's power is expertly modulated by an advanced engine management system, including rev limits of 12,300 rpms in all gears.
