Cranns Dual-Core Security System:
One Key Triple Protection for Every Ride
Why Do PM70 & PN70 Padlocks Share the Same Dimensions?
At Cranns, we know thieves don’t stop at one lock – and neither should your protection. Our PM70 (M-Core) and PN70 (N-Core) padlocks feature identical dimensions because we offer two complete security ecosystems, each with its own One Key Triple Protection system.
M-Core Series: Maximum Security for Motorcycles
- One key operates: VD14/VD10 (alarm disc lock) or Zero9 (disc lock) + PM70 (padlock)
- 16mm hardened core with 65,000+ combinations – France SRA certified (VD14 and VD10)
- Complete anti-theft solution: Alarm + Disc Lock + Padlock + Chain anchor
N-Core Series: Smart Protection for Scooters & Light Vehicles
- One key controls: VP6/RB6 (alarm disc locks) or Zero6 (disc lock) + PN70 (padlock)
- 12mm streamlined core (same 65,000+ combinations)
- Perfect for tight spaces on Vespa, e-bikes and bicycles
Key Advantages:
- Thieves typically carry tools for one lock type – our systems require defeating multiple mechanisms
- Same-key convenience means no fumbling with multiple keys
- Shared dimensions allow for identical mounting solutions across both security levels
Choose Your Security System:
- For heavy motorcycles: M-Core System (PM70 + VD14/VD10/Zero9)
- For scooters and light vehicles: N-Core System (PN70 + VP6/RB6/Zero6)
