XTREET SS 401 8V
Too aggressive to be ignored.
Conquer the city as if it were your personal court.

With a supersport design, racing spirit, and a mechanical response as sharp as a tight corner, the Xtreet SS 401 8V combines aggression, technology, and style in a single body. It's the ultimate machine for those seeking a powerful, engaging, and uncompromising driving experience.
You're not just looking at a motorcycle. You're looking at an extension of your soul.
