But it's when you come to looks that the Aprilia SR 50 DITECH breaks the mould. A no compromises sporty look inspired by everything connected with the world of racing - pure passion and thrills crystallise in an aggressive style, able to interpret and satisfy the needs and tastes of such a demanding and fashion conscious public as the very young. And what's more… it's a replica. Here are the new colours paying a tribute to the racing world, realm of the Noale company. They are SBK Replica, MotoGP Replica, Tuono Replica (Magnet Grey) and SportPro (Tulip Red). Four colour variations for a unique range to get about town with the colours of Noriuki Haga's Superbike, the bike brought to world 250 cc championship success by Macio Melandri, the invincible Tuono or the Aprilia's involved in the Sport Production class. Plus the coup de force, the Limited version, identical to the Spiderman Superbike used by Melandri at Mugello.

Going back to the technology, an important characteristic of the SR DITECH is the engine crankcase made from rubber reinforced polypropylene (to reduce vibrations and noise) and glass reinforced polypropylene (to increase rigidity and resistance to abrasion). Lighter and more functional, it guarantees the perfect configuration for this innovative high-technology engine.
The SR 50 DITECH has a generous and reliable "heart" representing the maximum of technology applied to a two-stroke engine. The sophisticated APRILIA DITECH electronic direct injection engine enables never-before-seen performance, consumption and emissions to be obtained.
