THE LATEST AND MOST SPECTACULAR EVOLUTION OF A SPORT NAKED DYNASTY
A direct descendant of the RSV4, the seven-time World SBK champion bike and newly crowned champion on the Superstock 1000 FIM Cup, Tuono V4 1100 is adrenaline in its purest state.
The performance of its unrivalled, revamped V4 has been increased to 1100 cc and 175 hp; more efficient to ride thanks to its revamped chassis and the further development of the already exceptional APRC electronics systems package, but at the same time more convenient and even safer for road use.
The more refined Factory version of the Aprilia Tuono V4 1100 comes with par excellence standard equipment unique in its category, borrowed from the king of superbike, the Aprilia RSV4 RF. The suspension section is made up of a trio of Öhlins elements (fork, rear shock absorber and steering damper) characterised by ultra fine tuning possibilities and a base setup that has been calibrated to give the rider maximum performance feedback in sport riding.
The fastest and sportiest naked
The latest and most spectacular evolution of a sport naked dynasty , born in 2002 out of Aprilia's intuition to strip down and fit a handlebar on their flagship superbike (which at the time was the V-twin RSV mille ), thereby combining all the advantages of a chassis par excellence with the fun of sitting up and dynamic riding. The patriarch of the new “supernaked” category was called the Tuono 1000 R, the first ultra high performance naked. Aprilia Tuono has therefore always been a high handlebar superbike, unbeatable on the track and loads of fun on the road.
The know-how acquired in years of victorious competition at top levels and the experience of the Tuono history now allow Aprilia to exceed limits which had previously seemed insurmountable: introducing the Tuono V4 1100 , an exclusive thrill generator and fun in its purest state.
Higher performance than the V4
The primary goal of the changes made to the already extraordinary Aprilia Tuono V4 engine was to increase torque, especially at medium-low revs in order to increase effectiveness and riding pleasure on the road. To achieve this goal the engine capacity was increased to a full 1077 cc thanks to the cylinder bore which was taken from 78 to 81 mm. This increase in displacement also resulted in higher top performance: the power peak went from 170 to 175 HP and places the Tuono V4 1100 range at the top of its segment (already at 8,000 rpm almost 20 HP more than before are available ). This makes the sport naked from Noale excel as a complete weapon for thrills and effectiveness with superlative torque values that dominate on the road and uncompromising top performance to dominate on the track.
The Tuono V4 1100 is the only naked powered by a 65° V4 engine° with unique characteristics. The narrow V architecture made it possible to build an engine with incredibly reduced longitudinal bulk which favours centring the weight and creating a compact chassis . As in previous models, the monobloc crankcase with integrated aluminium cylinder liners ensures maximum rigidity and consistent performance. The upper half of the engine case is now made with shell casting and has been lightened and reinforced; it also now has an optimised ventilation system in order to reduce power loss due to the internal pumping of the crankcase chambers. Also, the crankshaft now has connecting rod pins reduced to 36 mm in diameter with a weight increase of 0.45 Kg, the pistons are new and the Pankl connecting rods are lighter by a total of 400 grams.
The other technical particulars which made this engine so popular have remained unchanged, such as the removable gearbox and the innovative timing system kinematics: the chain camshaft drives only the intake camshaft which in turn drives the exhaust camshaft via a single gear. This solution allows for extremely compact heads especially in the area beneath the frame spars, much narrower than would otherwise be possible. A countershaft dampens vibrations even more than in a 90° V engine.
