Серед ключових останніх особливостей — вихлоп SC Project, який поєднується з новим карбоновим нижнім обтічником, розробленим спеціально для цієї моделі, а також переднім крилом, також із карбону. А результат? Зниження ваги на вражаючі 3 кг порівняно з класичною Aprilia RS 660. Менша вага означає більше задоволення від їзди!
