Ottimo prodotto, alla pari o forse anche meglio di Abus (li ho entrambi); lo uso sia con la sua catena o da solo come blocca disco e in entrambi i casi esprime un senso di robustezza e compattezza, sicuramente rappresenta un buon deterrente per i ladri di moto. Ovviamente come tutti i dispositivi antifurto presenti sul mercato non può garantire il 100% di sicurezza, dipende dalla capacità e organizzazione dei i ladri che rivolgono l’attenzione alla nostra moto. Personalmente l’ho usato in Italia e anche all’estero, in paesi e zone ad alto rischio di furto, e lucchetto e catena mi hanno salvato la moto in due tentativi di furto. Complimenti a Radikal.

Se ajusta en los discos de freno de la rueda delantera o trasera y se ve muy grueso y pesado con sensación de seguridad. Para un candado de esas características el tamaño es pequeño y fácil de guardar en el cajón. El envió llegó muy rápido.

I bought the RADIKAL after my previous cheap-and-cheerful motorbike disk-lock (also bought on Amazon) snapped in half without even trying. You get what you pay for. The new lock is seriously solid.
