The Aprilia Shiver 750 GT comes with the same sophisticated technical package as the Shiver, except for the engine which is a modern 90° V-twin - Euro 3. This engine, the first every mass-produced engine to use the integral Ride By Wire system, made its mark immediately thanks to its dynamic characteristics. Delivering 95 HP, it is not only the most powerful twin in its category; the engine also has a torque curve which comes in right from low revs making the bike competitive even with bikes fitted with bigger engines, as far as pulling power goes.
