Sulla base della filosofia KTM "Ready to Race", nascono due nuovi ATV dalle prestazioni estreme. XC 450 e 525 sono stati da poco presentati negli Stati Uniti, e saranno commercializzati in Europa non prima dell’estate 2008 I motori, entrambi raffreddati a liquido, saranno rispettivamente di 448 e 510 cc; gli ormai noti propulsori KTM sono stati ovviamente adattati all'uso ATV, in primis per il cambio a 5 marce, dotato di retro. KTM assicura rendimento elevato e manutenzione semplice. I carburatori Keihin FCR-MX 39 mm sono reattivi e di semplice sintonizzazione. Il telaio offre una perfetta centralizzazione delle masse, grazie al motore posto molto in basso. L'impianto frenante è affidato a Magura.
