The compact Mini T disc lock from Oxford might be small but it offers an excellent amount of security and is designed specifically for use with scooters and small motorcycles. Made from strong, durable and reliable alloy steel, the Mini T's 5.5mm locking pin simply slots through one of the drilled holes of the motorcycle brake disc and locks it in place. This will prevent the wheel from being rotated fully, meaning thieves can't simply ride or push your motorcycle away.
