Mammoth Security Heavy Duty Disc Lock With 10Mm Steel Pin

The Mammoth Security Heavy Duty Disc Lock is a motorcycle and scooter lock with a 10 mm hardened steel pin. It secures through the brake disc to immobilise the vehicle when parked.

It is compatible with most motorcycles and scooters that accept a 10 mm pin. The lock is described as resistant to cutting, drilling and tampering, and its bright colour enhances visibility as a theft deterrent. Security devices cannot prevent all theft; the source also notes that locks and chains used with a cover are effective deterrents.
